By using the definition of inverse functions we can see that:
a) g(7) = -10
b)(-10,7) is a point on h(x).
c)(7, -10) is a point on j(x)
How to evaluate the functions?Remember that if two functions f(x) and g(x) are inverses, then:
f(y) = x
g(x) = y
And also g(f(x)) = x = g(f(x)).
Here we know that functions h(x) and j(x) are inverses, and we also know that:
h(-10) = 7
So for the input -10, we have the output 7.
Then, by using the relation written above, we know that for the inverse function we must have:
j(7) = -10
That is the answer for a.
And for b and c the notation is (input, output), then:
(-10, 7) is a point on h.(7, -10)is a point on jThese are the answers of points B and C of the question.

siona bought 10 outfits to wear to church. the shirt has a price of $3.50 and a pair of shorts has a price of $4.00. how many shirts and pairs of shorts did she buy when she spent a total of $36.50?
Answers
Siona bought 7 shirts and 3 pairs of shorts when she spent a total of $36.50. The problem can be solved using a system of equations.
Let's use a system of equations to solve this problem:
Let x be the number of shirts that Siona bought, and y be the number of pairs of shorts that she bought. Then we have:
Equation 1: x + y = 10 (Siona bought 10 outfits in total)
Equation 2: 3.50x + 4.00y = 36.50 (The total cost of the outfits is $36.50)
To solve for x and y, we can use substitution or elimination. Let's use substitution:
From Equation 1, we can solve for x in terms of y:
x = 10 - y
Substitute this expression for x into Equation 2:
3.50(10 - y) + 4.00y = 36.50
Simplify and solve for y:
35 - 3.50y + 4.00y = 36.50
0.50y = 1.50
y = 3
Now we can substitute y = 3 back into Equation 1 to solve for x:
x + 3 = 10
x = 7
Therefore, Siona bought 7 shirts and 3 pairs of shorts when she spent a total of $36.50.

Chang needs to drive 11 miles to work. So far, he has driven 4.7 miles. How many more miles must he drive?
Answers
Answer:
6.3 miles
Step-by-step explanation:
11-4.7 = 6.3 hope this helps
He requires to travel 6.3 miles more to reach work.
Distance is the measure of how far apart two points are. It is a scalar quantity that is typically measured in units such as meters, kilometers, miles, feet, or inches.
Since the total distance required to be traveled by Chang is 11 miles.
Let S = total distance = 11
given distance traveled is 4.7 miles
take this traveled distance of 4.7 miles as x
now let S = x+y
replacing the given values where S = 11, x = 4.7
11= 4.7+y
y=11-4.7
y= 6.3
hence the remaining distance required to be traveled by Chang is 6.3 miles.

the weights of steers in a herd are distributed normally. the standard deviation is 300lbs and the mean steer weight is 1100lbs . find the probability that the weight of a randomly selected steer is between 1279 and 1609lbs
Answers
The probability that the weight of a randomly selected steer is between 1279 and 1609 lbs is 0.2288.
Given that the weights of steers in a herd are distributed normally.
The standard deviation is 300 lbs and the mean steer weight is 1100 lbs.
We are required to find the probability that the weight of a randomly selected steer is between 1279 and 1609 lbs.
Here, it is given that the mean weight of the herd is 1100 lbs and the standard deviation is 300 lbs.
We need to find the probability of the weight of a randomly selected steer between 1279 lbs and 1609 lbs.
It can be written as;
P (1279 ≤ X ≤ 1609)
We can standardize this distribution by subtracting the mean and dividing it by the standard deviation.
The standardized form is given by
Z = (X-μ)/σ
where X is the given value, μ is the mean and σ is the standard deviation.
Substituting the values we get,
for X = 1279
[tex]Z_1[/tex] = (1279 - 1100)/300 = 0.5967 and
for X = 1609
[tex]Z_2[/tex] = (1609 - 1100)/300 = 1.6967
We are required to find the probability of Z between [tex]Z_1[/tex] and [tex]Z_2[/tex].
P([tex]Z_1[/tex] ≤ Z ≤ [tex]Z_2[/tex]) To find this probability,
we use the standard normal distribution table,
We get P(Z ≤ 1.70) = 0.9545 and P(Z ≤ 0.60) = 0.7257
Now, P ([tex]Z_1[/tex] ≤ Z ≤ [tex]Z_2[/tex]) = P(Z ≤ 1.70) - P(Z ≤ 0.60) = 0.9545 - 0.7257 = 0.2288.

christina's pizza sells pizza by the slice for lunch. today, they sold 76 slices, including 20 slices of pepperoni pizza. what is the experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza?
Answers
The experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza is approximately 0.263
The experimental probability is found by dividing the number of times the desired outcome occurred by the total number of trials. In this case, the desired outcome is selling a slice of pepperoni pizza as the first slice tomorrow.
Since we only know the number of slices sold today, we don't have any specific information about the number of slices that will be sold tomorrow. However, we can assume that the same types of pizzas will be sold tomorrow, and the probability of selling a slice of pepperoni pizza tomorrow will be the same as the proportion of pepperoni slices sold today.
So, the experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza is
Experimental probability = Number of pepperoni slices sold today / Total number of slices sold today
Experimental probability = 20 / 76
Experimental probability = 0.263

Answers
Architects often create scale models before the actual building is constructed. if a scale model has a length of 24 inches and a width of 36 in., 2:3 the dimensions are geometrically similar to the model buildings
Geometrically similar to the model buildings are those whose ratio of corresponding dimensions are the same as those of the model.
The ratio of the dimensions of the scale model is:
length:width = 24:36 = 2:3
There are two ratios to compare in a building with dimensions L and W:
length : width = L:W and
width : length = W:L
The ratio of the dimensions of a building must be in proportion to the ratio of the dimensions of the scale model for geometric similarity.
Since the dimensions of the model are 2:3, the dimensions of the building must also be in a 2:3 ratio.
Therefore, we have: L : W = 2:3
L = (2/3)W
The ratio of the length to the width of the building is 2:3.

find n 3ft area=33 sq ft
Answers
The dimensions of the rectangle are 6 ft by 5.5 ft, and n = 6.
What is the area of the rectangle?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
We know that the area of a rectangle is given by:
Area = Length x Width
Since the problem does not specify the shape of the rectangle, we cannot assume that it is a square. Therefore, we need to find two numbers whose product is 33.
The factors of 33 are 1, 3, 11, and 33. None of these factors is equal to 3, so we cannot simply multiply 3 by a factor of 33 to get the length of the rectangle. Therefore, we need to use a different approach.
One way to find two numbers whose product is 33 is to start with the square root of 33 and round up and down to the nearest integer. The two resulting integers will be close to the factors of 33 and will multiply to give 33.
The square root of 33 is approximately 5.74. Rounding up and down to the nearest integer gives:
Length = 6 ft
Width = 33 ÷ 6 = 5.5 ft (approximately)
The product of these two numbers is:
6 ft x 5.5 ft ≈ 33 sq ft
Therefore, the dimensions of the rectangle are 6 ft by 5.5 ft, and n = 6.

26. In the given figure, OP || RS. ZPQR = 60° and QRS = 130°. Then what is the measure of ZOPQ? S P 60% R 130⁰
Answers
Answer: The answer is 60.
Step-by-step explanation:
Using the fact that OP || RS, we know that∠RWV = 180° − 130° 1. ∠RWV = 50° We know that,∠PWQ = ∠RWV = 50° (Since, opposite angles of intersecting lines are equal) Also, for line OP∠OQP + θ = 180° θ = 180° − ∠OPQ = 180° − 110° 2. θ = 70°
Answer:
The measure of ∠OPQ is 110°.
Step-by-step explanation:
Draw a line parallel to OP from point Q. Label a point on the line T. (See attached diagram).
Angles SRQ and TQR are alternate interior angles, and so according to the Alternate Interior Angles Theorem, they are congruent.
⇒ m∠TQR = m∠SRQ = 130°
Given m∠PQR = 60° and m∠TQR = 130° then:
⇒ m∠TQP + m∠PQR = m∠TQR
⇒ m∠TQP + 60° = 130°
⇒ m∠TQP = 70°
Angles OPQ and TQP are same-side interior angles, and so according to the Same-side Interior Angles Theorem, they are supplementary (sum to 180°).
⇒ m∠OPQ + m∠TQP = 180°
⇒ m∠OPQ + 70° = 180°
⇒ m∠OPQ = 110°
Therefore, the measure of ∠OPQ is 110°.

the 98.4% confidence interval for snapdragons grown in compost is (20.91, 38.43). what is the margin of error of this confidence interval?
Answers
The margin of error of the 98.4% confidence interval for snapdragons is 3.71.
The midpoint of the range is calculated by adding the upper and lower bounds and then dividing by two. So, the sample mean is `(20.91 + 38.43) / 2 = 29.67`.
The margin of error is calculated by multiplying the critical value of z* (1.96 for a 98.4% confidence level) by the standard error of the mean. The formula for calculating the margin of error is:
`Margin of error z*(standard deviation/√n`).
The formula is `range/4 = 1.96 * standard deviation/√n`.Now, solve for the standard deviation:
`standard deviation = (range/4) * √n / 1.96`
Substituting the values: `(38.43 - 20.91)/4 = 1.96 * standard deviation/√n`
Simplifying the equation: `4.26 = (1.96*standard deviation)/√n`
Squaring both sides: `4.26^2 = 3.8416 = (1.96^2 * standard deviation^2)/n`
Substituting the value of the standard deviation: `3.8416 = (1.96^2 * ((38.43 - 20.91)/4)^2) / n`
Solving for n: `n = ((1.96^2 * ((38.43 - 20.91)/4)^2) / 3.8416) = 31.54`
Now that we know the sample size, we can calculate the standard error of the mean:
`standard error = standard deviation/√n = ((38.43 - 20.91)/4)/√31.54 = 1.89`.
The margin of error is `1.96 * 1.89 = 3.71`.
The 98.4% confidence interval for snapdragons grown in compost is (20.91, 38.43). The margin of error of this confidence interval is 3.71.

tickets for a raffle cost 5. there were 833 tickets sold. one ticket will be randomly selected as the winner, and that person wins 1400 and also the person is given back the cost of the ticket. for someone who buys a ticket, what is the expected value (the mean of the distribution)?
Answers
The expected value (the mean of the distribution) for someone who buys a ticket can be calculated by adding up the total amount of money in the raffle and then dividing that by the number of tickets sold, which in this case in $6.68.
In this scenario, a ticket costs $5. The prize for winning the raffle is $1400 plus the cost of the ticket, which is $5.
The total value of the raffle is equal to the sum of the prize and the total amount of money raised from the tickets. The amount raised from the tickets is the number of tickets sold multiplied by the cost of the ticket.
Therefore, the total value of the raffle is equal to: $1400 + ($5 × 833) = $1400 + $4165 = $5565
The expected value of a ticket is the total value of the raffle divided by the number of tickets sold.
Therefore, the expected value of a ticket is:$5565 / 833 = $6.68
Therefore, the expected value (the mean of the distribution) for someone who buys a ticket is $6.68.

what is the approximate probability that the actual proportion requiring aid will exceed that value? (round your answer to four decimal places.)
Answers
The approximate probability that the actual proportion requiring aid will exceed 0.08 is 0.5 (or 50%) rounded to four decimal places.
Given: The number of members in town = 400
The number of members requiring aid = 32
The proportion of members requiring aid = (number of members requiring aid) / (total number of members) = 32 / 400 = 0.08
To find the approximate probability that the actual proportion requiring aid will exceed this value, we need to assume a distribution for the proportion of members requiring aid. Assuming a normal distribution, we can use the Central Limit Theorem to approximate the sampling distribution of the sample proportion.
The standard error of the sample proportion is given by:
SE = √[p(1-p)/n]
where p is the population proportion and n is the sample size.
Substituting the values, we get:
SE = sqrt [(0.08 × 0.92) / 32] = 0.043
To find the probability that the actual proportion requiring aid will exceed 0.08, we can standardize the distribution using the z-score formula:
z = (x - p) / SE
where x is the value of the proportion we are interested in, p is the population proportion, and SE is the standard error of the sample proportion.
Substituting the values, we get:
z = (0.08 - 0.08) / 0.043 = 0
The probability that the actual proportion requiring aid will exceed 0.08 is equal to the probability of observing a z-score greater than 0, which is 0.5 (or 50%).

The least likely event from given events is Option B: A randomly selected student who is freshmen owns a skateboard.
The event whose occurence is minimum is least likely event.
Suppose there are finite elementary events in sample space of considered experiment and all are equally likely.
Then, we want to find the probability of an event E.
Then, its probability is given as
P(E) = Number of favourable cases/ Number of total cases = n(E)/n(S)
where favorable cases are the elementary events who belong to E, and total cases are size of sample space.
For two events A and B, by chain rule, we have:
P(A∩B) = P(B)P(A|B) = P(A)P(A|B)
How to find the conditional probability:
Suppose that there are two events A and B. Then suppose the conditional probability are:
P(A|B) = probability of occurrence of A given B has already occurred.
P(B|A) = probability of occurrence of B given A has already occurred.
We can then use the chain rule to find them, or Bayes theorem also helps in finding these probabilities.
We are given the table of joint relative frequency:
We take events as A, A' and B and B'
Important probabilities which will be used are evaluated as:
P(A) = n(A)/n(S) = 150/1200 = 1/8
P(B) = n(B)/n(S) = 250/1200 = 5/24
P(A') = 1 - P(A) = 7/8
P(B') = 1 - P(B) = 1 - 5/24 = 19/24
P(A∩B) = n(A∩B) / n(S) = 40/1200 = 1/30
P(A'∩B') = n(A'∩B') / n(S) = 840/1200 = 7/10
P(A'∩B) = n(A'∩B) / n(S) = 210/1200 = 7/40
Evaluating probabilities of choices given, we get:
Case 1: E = A random selected student who owns skateboard is freshmen
P(E) = ?
P(E) = P(B|A) = P(A∩B) / P(A) = 1/30 ÷ 1/8 = 4/15
Case 2: E = A random selected student who is freshmen owns skateboard:
P(E) = P(A|B) = P(A∩B) / P(B) = 1/30 ÷ 5/24 = 4/25
Case 3: E = A random selected student who doesn't owns skateboard is freshmen
P(E) = P(B|A') = P(A'∩B) / P(A') = 7/40 ÷ 19/24 = 21/95
Case 4: E = A randomly selected student who doesn't owns skateboard is not freshmen
P(E) = P(B'|A') = P(A'∩B') / P(A') = 7/10 ÷ 19/24 = 84/95
So, the least probability is for second case.

After we planted flowers in 2/5 of our garden, 24m squared remained unplanted. How many square meters is this garden in total? if the total area of the garden is 1 the proportion of the remaining area is?
Answers
Thus, total garden area calculated in square meters is found to be 40 sq. m.
Explain about the one-variable linear equation?If the degree n in the equation is equal to 1, then a linear equation only contains ONE variable. The highest exponent a single variable can have is referred to as the equation's degree. Any arbitrary variable, such as x, y, or z, may be used as long as the linear equation is homogeneous.
Given data:
Let x be the total area of land.
Area of planted flowers : 2/5 x
Remaining area = 24 sq. m.
Thus,
Total area = Area of planted flowers + Remaining area
x = 2/5 x + 24
x - 2/5 x = 24
(5 -2)/5 x = 24
3x/5 = 24
x = 24*5 / 3
x = 8*5
x = 40
Thus, total area of the garden calculated in square meters is found to be 40 sq. m.

i need help i cant figure out math
Answers
Answer:
See below.
Step-by-step explanation:
to find the change in temperature from 2:00 PM to 10:00 PM, you need to subtract the final temperature from the initial temperature. In other words,
Change in temperature = Final temperature - Initial temperature
In your problem, the final temperature is -9°F and the initial temperature is 18°F. Therefore,
Change in temperature = -9°F - 18°F
Change in temperature = -27°F
So, the change in temperature from 2:00 PM to 10:00 PM is -27°F.

Answers
The relative frequency for the event "spin a 2" is 1/5.
What is the relative frequency?Relative frequency measures how often a value appears relative to the sum of the total values.
In order to determine the relative frequency of spinning a 2, divide the frequency of spinning a two by the total number of trials.
Division is the process of determining the quotient of two or more numbers. It entails grouping a number into equal parts using another number. The sign that is used to represent division is ÷.
Relative frequency = number of times a two was spun / total number of trials
= 10 / 50 = 1/5
