Step-by-step explanation:
how many positive odd integers less than 10,000 can be written using digits 3,4,6,8, and 0
the total number of positive odd integers less than 10,000 that can be written using the digits 3, 4, 6, 8, and 0 is 64 + 64 = 128.
Why is it?
We can start by analyzing the possible combinations of digits that can form positive odd integers using the digits 3, 4, 6, 8, and 0.
For a number to be odd, the units digit must be 3, 5, 7, or 9. Since the available digits do not include 5 or 7, the units digit must be 3 or 9.
Case 1: Units digit is 3
In this case, we have four remaining digits (0, 4, 6, and 8) to use for the thousands, hundreds, and tens places. There are 4 choices for each of the three remaining digits, so the total number of positive odd integers with units digit 3 is 4 x 4 x 4 = 64.
Case 2: Units digit is 9
Similar to case 1, there are four remaining digits (0, 4, 6, and 8) to use for the thousands, hundreds, and tens places. Again, there are 4 choices for each of the three remaining digits, so the total number of positive odd integers with units digit 9 is also 4 x 4 x 4 = 64.
Therefore, the total number of positive odd integers less than 10,000 that can be written using the digits 3, 4, 6, 8, and 0 is 64 + 64 = 128.

a photograph has a length that is 6 inches longer than its width, x. so its area is given by the expression square inches. if the area of the photograph is square inches, what is the width of the photograph?
The width of the photograph is approximately 10.5 inches.
Let's first write an expression for the length of the photograph in terms of its width
Length = Width + 6 inches
And we know that the area of the photograph is given by
Area = Length × Width
Substituting the expression for the length, we get
Area = (Width + 6) × Width
Simplifying this expression, we get
Area = Width^2 + 6 Width
We are given that the area of the photograph is 132 square inches. So we can set up an equation
132 = Width^2 + 6 Width
Rearranging this equation, we get a quadratic equation in standard form
Width^2 + 6 Width - 132 = 0
Now we can solve for the width using the quadratic formula
Width = (-6 ± √(6^2 - 4(1)(-132))) / (2(1))
Width = (-6 ± √(1416)) / 2
We can simplify this expression
Width = (-3 ± √354)
Since the width must be positive, we can discard the negative solution
Width = (-3 + √354) ≈ 10.5 inches

Answer:
Since the sample space contains 36 equally likely outcomes, each outcome has a probability of 1 / 36.
We know that probability is defined as number of favourable outcomes divided by total number of outcomes.
Step-by-step explanation:
An experiment occurs of rolling two fair number cubes.
We have given number of favourable outcomes = 2 {(2,1), (1,2)}
Number of Total Outcomes = 36
So ,
Probability = Number of favourable outcomes / Total Outcomes
P(1 and 2) refers to the probability of rolling a 1 on the first cube and a 2 on the second cube. There is only one outcome that satisfies this condition, which is (1, 2).
P(1 and 2) = 2 / 36

Using trigonometric ratios find the missing side. Round to the nearest tenth.
The length of missing side AC ≈ 10.9.
What is length of side?
To find the missing side of the right triangle, we can use the trigonometric ratios, specifically the sine, cosine, and tangent ratios.
Given that B is a right angle, we know that:
sin A = opposite/hypotenuse = BC/AB
cos A = adjacent/hypotenuse = AC/AB
tan A = opposite/adjacent = BC/AC
Substituting the known values, we get:
sin 33° = BC/13
cos 33° = x/13
tan 33° = BC/x
Solving for x, we can use the cosine ratio:
cos 33° = x/13
x = 13 cos 33°
x ≈ 10.88
Therefore, the missing side AC ≈ 10.9.
What is hypotenuse?
In a right triangle, the hypotenuse is the longest side and the side that is opposite the right angle. It is also the side that connects the two legs of the right triangle. The hypotenuse is always opposite the right angle and is also the side that has the largest length compared to the other two sides (the legs) of the triangle.
The hypotenuse plays a crucial role in the Pythagorean theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. The Pythagorean theorem is expressed mathematically as: a² + b² = c²
where a and b are the lengths of the legs of the right triangle, and c is the length of the hypotenuse.

To complete the table, we need to calculate the number of days Kimimela fed her rabbits for each given percentage. To do this, we can use proportions.
For example, to find out how many days Kimimela fed her rabbits if she fed them 20% of the time, we can set up the proportion:
20/100 = x/350
where x is the number of days Kimimela fed her rabbits. Cross-multiplying, we get:
100x = 20 * 350
Solving for x, we get:
x = 20 * 350/100 = 70
So, if Kimimela fed her rabbits 20% of the time, she fed them for 70 days.
Using the same method, we can complete the table as follows:

The group with the largest uncertainty error in a 95% confidence level among Group A, B, C, and D is Group D.
To determine the uncertainty error for each group, we'll calculate the margin of error using the formula:
Margin of Error = t (95%) × (sample deviation / sqrt(sample size))
Assuming a t (95%) value of 2.0 and a sample size of 25 for all groups, we have:
Group A:
Margin of Error = [tex]2.0 × (0.51 / sqrt(25)) = 2.0 × (0.51 / 5) = 0.204[/tex]
Group B:
Margin of Error =[tex]2.0 × (0.06 / sqrt(25)) = 2.0 × (0.06 / 5) = 0.024[/tex]

Group D:
Margin of Error = [tex]2.0 × (2.00 / sqrt(25)) = 2.0 × (2.00 / 5) = 0.8[/tex]
Based on the margin of error calculations, Group D has the largest uncertainty error at a 95% confidence level, with a

g how can you describe the standard deviation in part c relative to the population standard deviation from which the samples were generated?
If the sample size in part c is larger, then the sample standard deviation will be a better estimate of the population
standard deviation. If the sample size is smaller, then the sample standard deviation will be less reliable and may not
be a good estimate of the population standard deviation.
To describe the standard deviation in part c relative to the population standard deviation from which the samples were
generated, you can use the concept of the sample standard deviation.
The sample standard deviation is a measure of the variation in a set of data that is calculated by taking the square root
of the variance of the data set. The variance is the average of the squared differences from the mean. It is important to
note that the sample standard deviation is an estimate of the population standard deviation, which is the true measure
of the variability in the population. The larger the sample size, the closer the sample standard deviation will be to the
population standard deviation. Therefore, if the sample size in part c is larger, then the sample standard deviation will
be a better estimate of the population standard deviation.
Conversely, if the sample size is smaller, then the sample standard deviation will be less reliable and may not be a
good estimate of the population standard deviation.

What is probability ?
Probability is a mathematical concept used to measure the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. Probabilities between 0 and 1 represent the degree of uncertainty or likelihood of the event occurring.
For example, if a fair coin is tossed, the probability of it landing heads up is 0.5, since there are two equally likely outcomes (heads or tails) and only one of them is heads. Similarly, the probability of drawing a spade from a standard deck of 52 cards is 1/4 or 0.25, since there are four suits and only one of them is spades.
Probability theory is used extensively in many fields, including statistics, science, engineering, finance, and more, to model and analyze uncertain events and make informed decisions.
This is because the bar graph represents the frequency or probability of occurrence of each color, and the given probabilities in the table match with the corresponding frequencies represented in the bar graph.

Z = (X - μ) / σ
Substituting the values for μ and σ, we get,
⇒Z = (X - 79) / 20
The probability of 55 ≤ X ≤ 103,
Calculate the corresponding z-scores for 55 and 103,
And then calculate the probability of the interval between these two z-scores using a standard normal table .
The z-score for 55 is,
Z = (55 - 79) / 20
= -1.2
The z-score for 103 is,
Z = (103 - 79) / 20
= 1.2
Using a standard normal table or calculator, the probability of the interval between these two z-scores is,
P(-1.2 ≤ Z ≤ 1.2) ≈ 0.7745
Therefore, the probability that a bill for veterinary services costs between $55 and $103 is approximately 0.7745, or 77.45%.

Sarita recorded the number of minutes the bus was late over several days. Organize her data into a frequency table. 3,7,0,4,10,6,8,5,3,11,12,0,7,4,8,17,15,12,13,5
Step-by-step explanation:
To create a frequency table for Sarita's data, we need to first count the number of times each value appears in the data set. We can then organize this information into a table with two columns: one for the values and one for their frequencies.
Here is the frequency table for Sarita's data:
Value Frequency
0 2
3 2
4 2
5 2
6 1
7 2
8 2
10 1
11 1
12 2
13 1
15 1
17 1
To create this table, we first counted the number of times each value appears in the data set. For example, the value 0 appears twice, so its frequency is 2. We repeated this process for each value in the data set, and then organized the results into a table with two columns.
Leah and Josh are buying a $550,000 home. They have been approved for a 3.70% APR mortgage. They made a 14% down payment and will be closing on September 6. How much should they expect to pay in prepaid interest at the closing?
Leah and Josh should expect to pay approximately $1,204.31 in prepaid interest at the closing.
What is interest?
Interest is the amount of money that is paid or earned for the use of borrowed or invested funds. When someone borrows money, they typically have to pay back the principal (the amount borrowed) plus interest, which is usually calculated as a percentage of the principal.
To calculate the prepaid interest at closing, we need to first determine the loan amount, which is the purchase price of the home minus the down payment:
Purchase price = $550,000
Down payment = 14% of $550,000 = $77,000
Loan amount = $550,000 - $77,000 = $473,000
Next, we need to calculate the daily interest rate by dividing the APR by 365:
Daily interest rate = 3.70% / 365 = 0.010137%
Finally, we can calculate the prepaid interest by multiplying the loan amount by the daily interest rate and the number of days from the closing date to the end of the month:
Number of days from September 6 to September 30 = 25
Prepaid interest = $473,000 x 0.010137% x 25 = $1,204.31
Therefore, Leah and Josh should expect to pay approximately $1,204.31 in prepaid interest at the closing.

a certain zookeeper has n cages in a row and two indistinguishable lions. the lions have ot be in separate cages, and they may not be placed in adjacent cages. how many ways could the zookeeper assign lions to cages?
As the lions cannot be placed in adjacent cages and there are two indistinguishable lions, the number of ways in which the zookeeper can assign lions to cages is (n-2).
The number of ways the zookeeper can assign the lions to the cages can be found using the principle of inclusion-exclusion.
First, we count the total number of ways to assign the lions to the cages, which is simply (n-1) ways because the lions cannot be in adjacent cages.
Next, we subtract the number of ways the lions can be in adjacent cages. Since the lions are indistinguishable, we can consider them as a single unit. Thus, we have (n-2) ways to place this unit in the cages.
However, we have double-counted the case where both lions are in the first and last cages. This can only happen once, so we need to add it back in. Thus, we add 1 to our previous result.
Putting this all together, we have:
Total number of ways to assign lions to cages = (n-1) - (n-2) + 1 = n-2
Therefore, there are (n-2) ways for the zookeeper to assign the lions to the cages.

Thus, the measure of the value of 'x' for the given length of arc of circle is found as: x = 90.
Explain about the intercept chord theorem:The products of a measurements of the segments of two chords are equal if they overlap in a circle.
When two chords cross inside of a circle, the resulting angle's measure is equal to the product of the lengths of the arcs it intercepts and its vertical angle, divided by two.The intersecting chords theorem aids in determining how far apart various points on a circle are from a given location inside the circle.For the given arc length of circle:
Let the intersection of the both chords be 'O'.
m∠KOL = 180 - x ...eq 1 (linear pair).
By the intercept chord theorem:
m∠KOL = (arc JM + arcKL)
Put the value of eq 1.
180 - x = 1/2(30 + 2x - 30)
180 - x = 1/2 * 2x
180 = x + x
x = 180/2 = 90
Thus, the measure of the value of 'x' for the given length of arc of circle is found as: x = 90.

Suppose 20 chips are selected one by one at random and with replacement from an urn containing 5 red and 15 black chips. You win $4 for each red chip selected. Let the random variable X denote your winnings (the amount you win). a. To make this game "fair," how much should be charged to play? Why? (You must justify your answer.) b. Find Var (X). c. Find SDX). d. Now suppose you win $4 for each red chip selected and you lose S2 for each black chip selected. Let the random variable Y denote the amount you win or lose. Find E (Y). e. Now suppose you win $9 for each red chip selected and you lose Sc for each black chip selected. Find the value of that makes this is a "fair" game.
a. To make the game "fair," $1 should be charged to play.
b. The Var (X) is 4/5
c. The SDX is 0.894
d. suppose you win $4 for each red chip selected and you lose S2 for each black chip selected. Let the random variable Y denote the amount you win or lose. E (Y) is -34
e. To make this game "fair," $0.45 should be charged to play.
a. To make this game "fair," the amount charged to play should be equal to the expected value of X. The expected value of X is:
E(X) = (4/20) * 5 + (16/20) * 0 = 1
b. The variance of X can be calculated using the formula:
Var(X) = E(X²) - [E(X)]²
Since X can only take on the values 0 and 4, we have:
E(X^2) = (4/20)² * 5 + (16/20)² * 0 = 1/5
So,
Var(X) = 1/5 - 1² = -4/5
However, since the variance cannot be negative, we take the absolute value and say:
Var(X) = 4/5
c. The standard deviation of X is the square root of the variance:
SD(X) = √(4/5) ≈ 0.894
d. Let Y denote the amount won or lost, where Y = 4X - 2(20 - X) = 6X - 40. Then:
E(Y) = E(6X - 40) = 6E(X) - 40 = 6 - 40 = -34
So, on average, you would lose $34 per game.
e. To make the game "fair," we need to find the value of such that E(Y) = 0. Using the same formula as in part (d), we have:
E(Y) = E(9X - c(20 - X)) = 9E(X) - cE(20 - X) = 9E(X) - 20c
Setting E(Y) equal to 0 and solving for c, we get:
0 = 9 - 20c
c = 9/20 = 0.45

Ronnie had a certain number of movies, m. One-fourth of those movies were action movies. He sold eleven action movies to reach a grand total of four action movies.
m/4 - 11 = 4
What was the original number of movies Ronnie had?
A.
60
B.
56
C.
30
D.
45
the original number of movies Ronnie had was 60, which is option A.
Let's first understand the given problem. Ronnie had a certain number of movies, which we don't know and is represented by the variable 'm'. One-fourth of the total movies (m/4) were action movies. Now, Ronnie sold eleven action movies and ended up with only four action movies left. This means that he sold m/4 - 11 action movies, and the remaining action movies were 4. So, we can write the equation as:
m/4 - 11 = 4
Let's solve this equation to find the value of m. First, we will add 11 to both sides of the equation to get:
m/4 = 4 + 11
Simplifying this, we get:
m/4 = 15
Now, we will multiply both sides of the equation by 4 to get rid of the fraction:
m = 15 x 4
m = 60
Therefore, the original number of movies Ronnie had was 60, which is option A.
To explain this in more detail, we can use algebraic reasoning. We started with the equation m/4 - 11 = 4 and solved for m. To do so, we first added 11 to both sides of the equation to isolate the variable on one side. This gave us m/4 = 15. To solve for m, we multiplied both sides by 4 to cancel out the denominator and get m = 60.
Therefore, Ronnie originally had 60 movies, and one-fourth of those (m/4) were action movies. He sold 11 action movies, leaving him with only 4 action movies, and we were able to find the original number of movies using algebraic reasoning.
