Given:

\sin^{-1}\left(\dfrac{5}{8}\right)=A

To find:

The correct equivalent equation.

Solution:

We have,

\sin^{-1}\left(\dfrac{5}{8}\right)=A

Taking sin on both sides, we get

\sin \sin^{-1}\left(\dfrac{5}{8}\right)=\sin A

\dfrac{5}{8}=\sin A                      [\because \sin (\sin^{-1}\theta )=\theta]

Interchanging the sides, we get

\sin A=\dfrac{5}{8}

Therefore, the correct option is 4.

The following table gives results from two groups of students who took a nonproctored test. Use a 0.01 significance level to tes
Nana76 [90]

Answer:

Original claim is \mu_{1} =\mu_{2}

Opposite claim is \mu_{1} \neq \mu_{2}

Null and alternative hypotheses:

H_{0}:\mu_{1} = \mu_{2}

H_{1} : \mu_{1} \neq \mu_{2}

Significance level: 0.01

Test statistic:

We can use TI-84 calculator to find the test statistic and P-value. The steps are as follows:

Press STAT and the scroll right to TESTS

Scroll down to 2-SampTTest... and scroll to stats.

Enter below information.

\bar{x_{1}}=70.29

Sx1=22.09

n_{1} = 30

\bar{x_{2}}=74.26

Sx2=18.15

n_{2} = 32

\mu_{1} \neq \mu_{2}

Pooled: Yes

Calculate.

The output is in the attachment.

Therefore, the test statistic is:

t=-0.78

P-value: 0.4412

Reject or fail to reject: Fail to reject

Final Conclusion: Since the p-value is greater than the significance level, we, therefore, fail to reject the null hypothesis and conclude that the there is sufficient evidence to support the claim that the samples are from populations with the same mean.

90 POINTS PLEASE HELP

Formula

Volume = A_base * height

Solution

Synthetic Division always changes signs of the divisor. Also you add whereas in long division you subtract.

-2   ||  2   +    9  -  8   - 36

                   -4   -10     36

      ===================

          2       5     -18    0

You can eliminate A and B. You are never left with the same power at the beginning when you do a division.

What you are left with is

A_Base = 2x^2 + 5x - 18

Answer: D
