$1\%=\frac{1}{100}\\\\ 40.15\%\cdot 23=40.15 \cdot \frac{1}{100}\cdot 23=\frac{923.45}{100}=9.2345$

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~

This is actually a pretty easy question... all we have to do is 23 * 0.4015

We know that %40.15 = 0.4015, because 40.15/100 = 0.4015...

So 23 * 0.4015 = 9.2345

Decompose 3p-1/p^2-1 into partial fractions.

allsm [11]

Answer: $\frac{2}{p+1}+\frac{1}{p-1}$

Step-by-step explanation:

Decompose the denominator.

$p^2-1=(p+1)(p-1)$

So, 3 has to be multiplied by p-1 and p+1 has to be multiplied by 1.

For what value of the variable will the expression 8b−27 be equal to the following:<br> 5

qaws [65]

Answer:

We need to find the value of b to make 8b - 27 be equal to 5, so:

8b - 27 = 5

We solve the equation:

8b = 5 + 27

8b = 32

We divide both sides by 8:

b = 32/8 = 4

So now, we know that b=4, and we can verify:

8*4 - 27 = 5

32 - 27 = 5 TRUE

Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college. You survey 10

neonofarm [45]

Answer: 1.460

Step-by-step explanation:

Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.

Let $\mu$ represents the population mean .

Then, the set of hypothesis will be:-

$H_0: \mu=15$

$H_a:\mu\neq15$

We assume that this is normal distribution.

Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.

Sample mean : $\overliene{x}=16.2\ lbs$

Standard deviation : $\sigma=2.6$

The test statistic for population mean for small sample is given by :-

$t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

$t=\dfrac{16.2-15}{\dfrac{2.6}{\sqrt{10}}}=1.45951276623\approx1.460$

Hence , the value of test statistic = 1.460
