Hunter-Best [27]

8 / 2 = 45 / x....8 servings to 2 cups = 45 servings to x cups
cross multiply
(8)(x) = (2)(45)
8x = 90
x = 90/8
x = 11 1/4 (or 11.25) cups of flour are needed <==

Everything is in the picture please help asap.

NARA [144]

Answer:

$f(x)=x^2$

Step-by-step explanation:

All three functions in the figure are parabolic and thus share the parent function $y=x^2$ . They are horizontally dilated by some constant (unless they aren't) and can all be represented with $y=\pm ax^2$ , where $a$ is some constant.

Plug in point the line passes through to find that constant. For $f(x)$ , we can see the function clearly passes through (2,4):

$4=a\cdot 2^2,\\4=4a,\\a=1$

Therefore, the function of $f(x)$ is $f(x)=1x^2=\boxed{x^2}$

The heights of adult males in the United States are approximately normally distributed. The mean height is 70 inches (5 feet 10

steposvetlana [31]

Using the normal distribution, it is found that the probability is 0.16.

<h3>Normal Probability Distribution</h3>

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It 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, which is the percentile of X.

In this problem, the mean and the standard deviation are given by, respectively, $\mu = 70, \sigma = 3$ .

The proportion of students between 45 and 67 inches is the p-value of Z when <u>X = 67 subtracted by the p-value of Z when X = 45</u>, hence:

X = 67:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{67 - 70}{3}$

Z = -1

Z = -1 has a p-value of 0.16.

X = 45:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{45 - 70}{3}$

Z = -8.3

Z = -8.3 has a p-value of 0.

0.16 - 0 = 0.16

The probability is 0.16.
