${ \red{ \bold{option \: (d)}}} \: { \green{ \tt{ {2}^{8p} = {2}^{5p + 3}}}}$

Step-by-step explanation:

I said option (d) is correct. Because, the answer of 2^8 is 256 i.e.,

${ \green{ \bold{ {2}^{8} }}} = { \green{ \tt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2}}}$

${ \green{ \bold{ {2}^{8} }}} = { \green{ \tt{256}}}$

The value of 16^2 = 256.

Also, the answer of 2^5 is 32. i.e.,

${ \green{ \bold{ {2}^{5} }}} = { \green{ \tt{2 \times 2 \times 2 \times 2 \times 2}}}$

${ \green{ \bold{ {2}^{5} }}} = { \green{ \tt{32}}}$

A states division of motor vehicles claims that 60% of teens pass their drivers test on the first attempt. an investigative repo

____ [38]

Answer: There is convincing evidence at the the significance level that the DMV's claim is incorrect.

Step-by-step explanation:

Since we have given that

Hypothesis:

$H_0:p=0.6\\\\H_a:p\neq 0.6$

Probability of teens pass their drivers test on the first attempt = 60% = 0.60

Number of teens = 125

Number of them passed the tests on their first try = 86

$\hat{p}=\dfrac{86}{125}=0.688$

So, the value of test statistic would be

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.688-0.60}{\sqrt{\dfrac{0.6\times 0.4}{125}}}\\\\z=\dfrac{0.088}{0.0438}\\\\z=2.009\\\\z\approx 2.01$

At α = 0.05% level of significance, critical value = 1.645

Since 1.645 < 2.01

So, we will reject the null hypothesis.

Hence, there is convincing evidence at the the significance level that the DMV's claim is incorrect.

The y-intercept is the value of y when x is equal to zero. From the equation,

y = 500 + 50x

the y-intercept is calculated by:

y = 500 + 50(0) = 500

Therefore, the correct answer is option B. The y-intercept is 500; it represents the one-time campaign fee.

The function y=f(x) is graphed below. What is the average rate of change of the function f(x) on the interval -3 ≤ x ≤ 6

victus00 [196]

Answer:

Average ROC = 0

Step-by-step explanation:

Average ROC : (f(b) - f(a)) / (b - a) ... slope = (y'-y) / (x'-x)

a = -3 f(a) = 10 ... x=-3, y=10

b = 6 f(b) = 10 ... x'=6, y'=10

Average ROC = (10 - 10) / (6 - -3) = 0 / 9 = 0
