Answer:

904.32

Step-by-step explanation:

To solve a volume of sphere problem with a radius of six, we'll have to use the formula for the volume of a sphere, which is: 4/3 πr^3.  

Step 1: 6 to the power of 3.  This gives you 216.

Step 2: 216 times pi.  This gives you 678.24.

Step 3: 678.24 x 4/3.  In the end, this should give you 904.32.

Identify the relative maximum value of g(x) for the function shown below g(x)=7/x^2+5
Liula [17]
To find t<span>he relative maximum value of the function we need to find where the function has its first derivative equal to 0.

Its first derivative is -7*(2x)/(x^2+5)^2
</span>7*(2x)/(x^2+5)^2 =0 the numerator needs to be eqaul to 0
2x=0
x=0

g(0) = 7/5

The <span>relative maximum value is at the point (0, 7/5).</span>

Determine the sample size needed to construct a 99​% confidence interval to estimate the average GPA for the student population
Volgvan

Answer: n = 14

Step-by-step explanation: margin of error = critical value × σ/√n

Where σ = population standard deviation = 1

n = sample size = ?

We are to construct a 99% confidence interval, hence the level of significance is 1%.

The critical value for 2 tailed test at 1% level of significance is gotten from a standard normal distribution table which is 2.58

Margin of error = 0.7

0.7 = 2.58×1/√n

0.7 = 2.58/√n

By cross multipying

0.7×√n = 2.58

By squaring both sides

0.7^2 × n = 2.58^2

0.49 × n = 6.6564

n = 6.6564/0.49

n = 14
