What is Pythagoras theorem?
The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.
We know that Mrs. Kelley is standing 6 meters in front of Gabrielle, and Leslie is sitting to Gabrielle's right. We are also given that Mrs. Kelley and Leslie are 7 meters apart.
From the diagram, we can see that Mrs. Kelley and Gabrielle form a right triangle with Leslie as the vertex. Using the Pythagorean theorem, we can find the distance between Gabrielle and Leslie:
[tex]d^2 = (7)^2 - (6)^2d^2 = 49 - 36d^2 = 13[/tex]

ay went to an amusement park. The park charges an entrance fee of $10.50 and $4.50 for every ride. Jay spent $46.50 on entrance fees and rides. Which fuction can be used to find the number of rides he went on?
Answer:
The answer is 8
Step-by-step explanation:
Let total number of rides be represented by x
And total amount spent on the ride and entry fees be y
Entry fees of the park = $10.50
Also, Charge for each ride is given to be $4.50
So, The linear function which describes the situation :
y = 10.50 + 4.50x
Now, Its given that Jay spent a total of $46.50 in the park
So, to find total number of rides taken substitute y = 46.50 in the above linear equation.
⇒ 46.50 = 10.50 + 4.50x
⇒ 4.50x = 36
⇒ x ≈ 8
Thus, Number of rides taken = 8
The equation of line A is y = 7x + 12.
Line B is parallel to line A and passes through the point (2, 24).
What would be the solution to the system of equations represented by line A and line B?
A. R=7, y=61
B. The system of equations has an infinite number of real solutions.
C. The system of equations has no real solutions.
D. r=4,y=38
This equation is clearly not true, which means there is no real value of x that satisfies it. Therefore, the system of equations represented by line A and line B has no real solutions, the correct option is C.
Line A has a slope of 7, which means any line parallel to it will also have a slope of 7. Therefore, line B can be represented by the equation y = 7x + b, where b is the y-intercept that we need to find.
We know that line B passes through the point (2, 24), so we can substitute these values into the equation to get:
24 = 7(2) + b
Simplifying the right side gives:
24 = 14 + b
Subtracting 14 from both sides gives:
b = 10
Therefore, the equation of line B is y = 7x + 10.
Now we need to find the point of intersection between line A and line B, which is the solution to the system of equations represented by these two lines. To accomplish this, we can put the two equations equal to one another and find x:
7x + 12 = 7x + 10
Subtracting 7x from both sides gives:
12 = 10

what is the correct expression of the null hypothesis for the alternative hypothesis: the percentage of internet users who use the internet for shopping is greater than .40?
The null hypothesis for the alternative hypothesis "the percentage of internet users who use the internet for shopping is greater than 0.40" can be expressed as:
H0: p ≤ 0.40
Here, H0 represents the null hypothesis and p represents the proportion of internet users who use the internet for shopping.
The null hypothesis states that the percentage of internet users who use the internet for shopping is less than or equal to 40%.
In hypothesis testing, we collect data and analyze it to determine whether we can reject the null hypothesis or not.
If the data provides strong evidence against the null hypothesis, we reject it and accept an alternative hypothesis that suggests there is a significant relationship or difference.
However, if the data is not strong enough to reject the null hypothesis, we fail to reject it, but we cannot conclude that the null hypothesis is true.

An open circle is at 5 and a bold line starts at 5 and is pointing to the right. A number line from negative 3 to 3 in increments of 1. An open circle is at negative 5 and a bold line starts at negative 5 and is pointing to the left.
The correct representations of the inequality –3(2x – 5) < 5(2 – x) are:
-6x + 15 < 10 – 5x and x < 5
What is the inequality equation?
An inequality equation is a mathematical statement that compares two expressions using an inequality symbol such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).
Option 1: x < 5 – This is one of the correct representations. It is obtained by solving the inequality as follows:
-3(2x – 5) < 5(2 – x)
-6x + 15 < 10 – 5x (Distribute on the left and right sides)
-x < -5
x > 5 (Multiply both sides by -1 and reverse the inequality)
Option 2: -6x – 5 < 10 – x – This is not a correct representation. It is obtained by distributing on the left side but incorrectly distributing on the right side.
Option 3: -6x + 15 < 10 – 5x – This is one of the correct representations. It is obtained by distributing on the left and right sides, and then simplifying.
Option 4: x + 6 < 5x – 10 – This is not a correct representation. It is obtained by incorrectly distributing on the right side.
As for the number line representations:
The number line from negative 3 to 3 in increments of 1 with an open circle at 5 and a bold line starting at 5 and pointing to the right represents the solution x < 5, which is correct.
The number line from negative 3 to 3 in increments of 1 with an open circle at negative 5 and a bold line starting at negative 5 and pointing to the left does not represent the correct solution. There is no negative solution to this inequality, so there should not be an open circle or a bold line pointing to the left.

When women were finally allowed to become pilots of fighter jets, engineers needed to redesign the ejection seats because they had been originally designed for men only. The ejection seats were designed for men weighing between 140 lb and 201 lb. Weights of women are now normally distributed with a mean of 162 and a standard deviation of 46 lb . Complete parts (a) through (c) below.
Answer:
(a) What percentage of women would not be able to use the original ejection seats designed for men?
To answer this question, we need to find the percentage of women whose weight is outside the range of 140 lb to 201 lb, which is the weight range for which the original ejection seats were designed. We can do this by standardizing the weight distribution of women using the formula:
z = (x - μ) / σ
where z is the standard score, x is the weight of a woman, μ is the mean weight of women, and σ is the standard deviation of the weight of women.
Substituting the given values, we get:
z = (140 - 162) / 46 = -0.478
z = (201 - 162) / 46 = 0.848
Using a standard normal table or a calculator, we can find that the percentage of women whose weight is below 140 lb (corresponding to a z-score of -0.478) is 31.45%. Similarly, the percentage of women whose weight is above 201 lb (corresponding to a z-score of 0.848) is 19.34%. Therefore, the percentage of women who would not be able to use the original ejection seats designed for men is:
31.45% + 19.34% = 50.79%
(b) What weight range would accommodate 99.7% of the female pilots?
To find the weight range that would accommodate 99.7% of the female pilots, we need to find the z-scores that correspond to the 0.15% and 99.85% percentiles of the standard normal distribution. Using a standard normal table or a calculator, we can find that these z-scores are approximately -2.97 and 2.97, respectively.
Substituting these z-scores into the standardization formula, we get:
-2.97 = (x - 162) / 46
x = 63.88 lb
and
2.97 = (x - 162) / 46
x = 260.12 lb
Therefore, the weight range that would accommodate 99.7% of the female pilots is approximately 63.88 lb to 260.12 lb.
(c) What percentage of women would need ejection seats redesigned for them?
To find the percentage of women who would need ejection seats redesigned for them, we need to find the percentage of women whose weight is outside the weight range that would accommodate 99.7% of the female pilots. Using the values from part (b), we can see that the weight range that would accommodate 99.7% of the female pilots is approximately 63.88 lb to 260.12 lb. Therefore, the percentage of women who would need ejection seats redesigned for them is:
100% - 99.7% = 0.3%

find the answer (2√x) × (3³√x)
Answer:
6x^(3/2)
Step-by-step explanation:
To simplify the expression (2√x) × (3³√x), we can first use the properties of exponents to rewrite the cube root as a fractional exponent:
3³√x = x^(1/3)^3 = x^(1)
Using this, we can rewrite the expression as:
(2√x) × (3³√x) = 2x^(1/2) × 3x^(1)
To multiply these two terms, we can add the exponents since the bases are the same:
2x^(1/2) × 3x^(1) = 6x^(1/2 + 1) = 6x^(3/2)
Therefore, the simplified expression is 6x^(3/2).

A bag contains 6 red marbles, 4 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the exact probability that all three marbles drawn will be green?
the exact probability of drawing three green marbles from the bag is 0.0735 or approximately 7.35%.
To find the probability of drawing three green marbles from the bag, we need to use the formula for calculating the probability of multiple independent events. The probability of multiple independent events occurring together is the product of the individual probabilities of each event.
Let's first calculate the probability of drawing a green marble on the first draw. We have a total of 6 + 4 + 7 = 17 marbles in the bag, and 7 of them are green. So the probability of drawing a green marble on the first draw is:
P(green on first draw) = 7/17
After we draw a green marble on the first draw, we have 16 marbles left in the bag, including 6 red marbles and 4 blue marbles. Since we don't replace the marble after we draw it, the probability of drawing a green marble on the second draw is:
P(green on second draw) = 6/16
Finally, after we draw a green marble on the second draw, we have 15 marbles left in the bag, including 5 green marbles. So the probability of drawing a green marble on the third draw is:
P(green on third draw) = 5/15
To find the probability of drawing three green marbles in a row, we need to multiply these probabilities:
P(three green marbles) = P(green on first draw) x P(green on second draw) x P(green on third draw)
P(three green marbles) = (7/17) x (6/16) x (5/15)
Simplifying this expression, we get:
P(three green marbles) = (7 x 6 x 5) / (17 x 16 x 15)
P(three green marbles) = 0.0735
Therefore, the exact probability of drawing three green marbles from the bag is 0.0735 or approximately 7.35%.

a) 2 new printers
b) 11 min
Step-by-step explanation:
Given:
5 old printers take 30 min to produce a batch of comic books
4 new printers take 18 min to produce a batch of comic books
.
a) First, we need to find how long does one old and new printer take to produce a batch of comic books:
.
Since 5 old printers take 30 min to do the job, one printer would take 5 times more than this (5 printers work together and they do the job faster than one, that's why we have to multiply):
.
1 old printer does the job in:
5 × 30 = 150 min
1 new printer does the job in:
4 × 18 = 72 min
.
Since one old printer does the job in 150 min, 6 old printers would do this job 6 times faster (that's why we divide):
6 old printers would take:
150 / 6 = 25 min
2 new printers would take:
72 / 2 = 36 min
.
25 < 36
That means, 2 new printers would do this job faster
.
b) In order to find how much less time would this take, we have to subtract:

4.44 a company produces a computer battery that it claims last for 8 hours on a single charge with a standard deviation of 20 minutes. a random sampling of seven batteries are tested and found to have a sample standard deviation of 29 minutes. what is the chi-squared value and the predicted level of significance as represented by the test?
In order to determine the chi-squared value and the predicted level of significance as represented by the test, we need to conduct a hypothesis test. We will use the chi-squared test for a population variance. The null hypothesis is that the population variance is equal to 20 minutes squared (the square of the standard deviation), and the alternative hypothesis is that the population variance is greater than 20 minutes squared.
Therefore, the chi-squared value is calculated as:χ2 = (n - 1) × s2 / σ20where n is the sample size, s is the sample standard deviation, and σ0 is the hypothesized population standard deviation. Substituting the values given in the question, we get:χ2 = (7 - 1) × 29² / 20²= 21.19.
The degrees of freedom for this test are df = n - 1 = 6.Using a chi-squared distribution table with 6 degrees of freedom, we can find the predicted level of significance. For a chi-squared value of 21.19 and 6 degrees of freedom, the level of significance is less than 0.005. Therefore, we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the population variance is greater than 20 minutes squared.

For instance, the trinomial x2+6x+9 is a perfect square trinomial since it factors into (x+3)². The square of x is represented by the first term, x², and the square of 3 by the last term, 9. Its result 2(x)(3) is twice as long as the middle term 6x.
Y has a coefficient of -20. A fraction of -20 is -10.
-10 is squared to give 100.
As a result, we can add and take 100 to finish the square.
It is necessary to add and subtract the square of the y-half coefficient's in order to finish the square for y²–20y.
y²-20y+100-100
=(y-10)²-100

researchers observed 50 random people brush their teeth and recorded the number of seconds each person spent brushing. from the sample, they found a mean time of 41.5 seconds. further, their calculations revealed that this estimate is within a margin of error of 2.45 from the true average time that all people spend brushing their teeth. write the interval estimate that will estimate the true average time that people spend brushing their teeth. write your answer using inequality notation:
Answer:
The interval estimate is:
41.5 - 2.45 ≤ true average time ≤ 41.5 + 2.45
or
38.05 ≤ true average time ≤ 44.95
Inequality notation:
[38.05, 44.95]
The interval estimate that will estimate the true average time that people spend brushing their teeth is [39.05, 43.95] seconds.
Given that the mean time spent brushing teeth from the sample is 41.5 seconds, and the margin of error is 2.45 seconds, we can construct a confidence interval estimate using the formula:
(sample mean) ± (margin of error)
Substituting the given values, we get:
41.5 ± 2.45
Simplifying, we get:
[39.05, 43.95]
Therefore, we can be 95% confident that the true average time that all people spend brushing their teeth falls within this interval.

The distance from the park to Anita's house is 5 blocks, which is
5 blocks × 100 yards/block = 500 yards.
Answer:
A. 500 yards
Step-by-step explanation:
1 block = 100 yards
one leg: 4*100= 400 yards
second leg: 3*100= 300 yards
hypotenuse:
pythagorean theorem
hypotenuse ^2 = (one leg)^2 + (second leg)^2
hypotenuse ^2= (400)^2 + (300)^2
hypotenuse ^2 = 160,000 + 90,000
hypotenuse = sqrt(250,000)
hypotenuse = 500 yards
find the value of x.
Answer:
x = 55°
Step-by-step explanation:
Inscribed Angle Theorem says that the angle inside the circle is equal to 0.5 times the measurement of the arc it span. For example, the 70° spans 140° of the arc.
Create two equations to solve for x and r.
x = 0.5r
2r + 2(70) = 360
2r + 140 = 360
2r = 220
r = 110
x = 0.5 * 110
x = 55°
