Answer: 8.9
Step-by-step explanation:
To find the hypotenuse, use the formula [tex]a^2 + b^2 = c^2[/tex]
The two "legs" are a and b (it doesn't matter which leg is a and which leg is b), but the most important thing is that the hypotenuse is c.
So, we now know that we have to solve for c. To solve for c, substitute the values shown in the image for a and b.
[tex]a^2 + b^2 = c^2[/tex]
[tex]8^2+4^2=c^2[/tex]
[tex]16 + 64 = c^2[/tex]
[tex]80 = c^2[/tex]
[tex]\sqrt{80}[/tex] = c
Use a calculator, and after rounding, you get 8.9

A triangle has vertices of (-3,3),(-3,2), and (1,-2). What are the coordinates after dilating from the origin by a scale factor of 1/2?
Answer:
The coordinates after a dilating the triangle by a factor of 1/2 would be (-1.5, 1.5), (-1.5, 1) and (0.5, -1), respectively.
Step-by-step explanation:
Since we are dilating from the origin of the graph, (0, 0), all we need to do is multiply each vertex by the given scale factor.

The area of a rectangle is 91 square inches. If the length of the rectangle is 1 less than twice its width, write an equation that could be used to find the width, w, of the rectangle.
Answer:
(2w^2) + (-1w) + (-91)
Step-by-step explanation:
The equation that can be used to find the width, w, of the rectangle with the given area is: 2w² - w - 91 = 0.
What is the Area of a Rectangle?Area pf a rectangle = length × width
Given the following:
Area of rectangle = 91 in.²Width = wLength of the rectangle = 2w - 1Equation for finding w, using the area formula, would be:
(2w - 1)(w) = 91
2w² - w - 91 = 0
Therefore, the equation that can be used to find the width, w, of the rectangle with the given area is: 2w² - w - 91 = 0.

Answer:
[tex]Area = 3846.5cm^2[/tex]
Step-by-step explanation:
Given
[tex]d = 35cm[/tex]
[tex]\pi = 3.14[/tex]
Required
The area of the ball
A soccer [tex]ball[/tex]has the shape of a [tex]sphere[/tex]. So, the area is:
[tex]Area = 4\pi(\frac{d}{2})^2[/tex]
So, we have:
[tex]Area = 4 * 3.14 * (\frac{35}{2})^2[/tex]
[tex]Area = 4 * 3.14 * (17.5)^2[/tex]
Using a calculator, we have:
[tex]Area = 3846.5cm^2[/tex]

Assume that 24.5% of people have sleepwalked. Assume that in a random sample of 1478 adults, 369 have sleepwalked. a. Assuming that the rate of 24.5% is correct, find the probability that 369 or more of the 1478 adults have sleepwalked.
b. Is that result of 369 or more significantly high? c. What does the result suggest about the rate of 24.5%?
Answer:
a) 0.3483 = 34.83% probability that 369 or more of the 1478 adults have sleepwalked.
b) 369 < 403.4, which means that 369 is less than 2.5 standard deviations above the mean, and thus, a result of 369 is not significantly high.
c) Since the sample result is not significant, it suggests that the rate of 24.5% is a good estimate for the percentage of people that have sleepwalked.
Step-by-step explanation:
We use the normal approximation to the binomial to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
A result is considered significantly high if it is more than 2.5 standard deviations above the mean.
Normal probability distribution
Problems of normally distributed distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].
Assume that 24.5% of people have sleepwalked.
This means that [tex]p = 0.245[/tex]
Sample of 1478 adults:
This means that [tex]n = 1478[/tex]
Mean and standard deviation:
[tex]\mu = 1478*0.245 = 362.11[/tex]
[tex]\sigma = \sqrt{1478*0.245*0.755} = 16.5346[/tex]
a. Assuming that the rate of 24.5% is correct, find the probability that 369 or more of the 1478 adults have sleepwalked.
Using continuity correction, this is [tex]P(X \geq 369 - 0.5) = P(X \geq 368.5)[/tex], which is 1 subtracted by the p-value of Z when X = 368.5.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{368.5 - 362.11}{16.5346}[/tex]
[tex]Z = 0.39[/tex]
[tex]Z = 0.39[/tex] has a p-value of 0.6517
1 - 0.6517 = 0.3483
0.3483 = 34.83% probability that 369 or more of the 1478 adults have sleepwalked.
b. Is that result of 369 or more significantly high?
362.11 + 2.5*16.5346 = 403.4
369 < 403.4, which means that 369 is less than 2.5 standard deviations above the mean, and thus, a result of 369 is not significantly high.
c. What does the result suggest about the rate of 24.5%?
Since the sample result is not significant, it suggests that the rate of 24.5% is a good estimate for the percentage of people that have sleepwalked.

A pitcher contains 2 liters of liquid. Jin pours 368 milliliters of this liquid into a test tube.
How much liquid is left in the pitcher?
Enter your answer in the box.
Answer:
1,632 liters of liquid remain in the pitcher.
Step-by-step explanation:
Given that a pitcher contains 2 liters of liquid, and Jin pours 368 milliliters of this liquid into a test tube, to determine how much liquid is left in the pitcher the following calculation must be performed:
368 milliliters = 0.368 liters
2 - 0.368 = X
1.632 = X
Therefore, 1,632 liters of liquid remain in the pitcher.
