Which function's graph is shown below?

STALIN [3.7K]

Answer:

A. y = cos x

Step-by-step explanation:

The function that we see graphed has the point (0,1), this means whichever trig function f(x) it represents f(0) = 1.

Now, only the cosine function has the property that cos(0) = 1, thus choice A is the correct answer.

Reil [10]

Answer:

Each vehicle received $\frac{3}{20}$ of the total capacity of the storage tank

Step-by-step explanation:

we know that

To find out what part of the total capacity of the storage tank that each vehicle received, divide three fourths by five

$\frac{(3/4)}{5}=\frac{3}{20}$

therefore

Each vehicle received $\frac{3}{20}$ of the total capacity of the storage tank

On a test with a population mean of 75 and standard deviation equal to 16, if the scores are normally distributed, what percenta

sashaice [31]

Answer:

Percentage of scores that fall between 70 and 80 = 24.34%

Step-by-step explanation:

We are given a test with a population mean of 75 and standard deviation equal to 16.

Let X = Percentage of scores

Since, X ~ N( $\mu,\sigma^{2}$ )

The z probability is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1) where, $\mu$ = 75 and $\sigma$ = 16

So, P(70 < X < 80) = P(X < 80) - P(X <= 70)

P(X < 80) = P( $\frac{X-\mu}{\sigma}$ < $\frac{80-75}{16}$ ) = P(Z < 0.31) = 0.62172

P(X <= 70) = P( $\frac{X-\mu}{\sigma}$ < $\frac{70-75}{16}$ ) = P(Z < -0.31) = 1 - P(Z <= 0.31)

= 1 - 0.62172 = 0.37828

Therefore, P(70 < X < 80) = 0.62172 - 0.37828 = 0.24344 or 24.34%

Soloha48 [4]

You have to find an equivalent denominator. The two fractions are 1/12 and 6/8. I'll show you some work.

6/8 ; 12/16 ; 18/24

1/12 ; 2/24

Now that we know the denominator is 24, we can simplify 18/24.

18/24 ; 9/12

Your answer should be 9/12. Hope this helps! :)
