When finding the volume of this shape, there would practically be a formula that we would have to use, in order to solve this on how we are suppose to do.

We know that the radius would then be 4, and therefore, we would just plug this in into the formula which would be illustrated below.

$\boxed{V= \frac{4}{3} \pi r^3}$

All we would have to do, is to plug the number 4 into the proper location in the formula.

In a decimal form, your correct answer would then be 268.08.

By as we can see above, we would have to convert the decimal form, into a fraction form, and this would be shown below.

$\left[\begin{array}{ccc}\boxed{3*8=24-8=256/3}\end{array}\right]$

Your correct answer should be (option a)

. One sample has M = 18 and a second sample has M = 14. If the pooled variance for the two samples is 16, what is the value of C

dalvyx [7]

Answer:

Cohen's d : 1.00

Step-by-step explanation:

We know that M₁ = 18, and M₂ = 14. Given that the pooled variance for the these two samples are 16, S²Pooled = 16, and therefore S - pooled = 4.

The formula to solve for the value of Cohen's d is as follows,

d = M₁ - M₂ / S - pooled,

d = 18 - 14 / 4 = 4 / 4 = 1

Therefore the value of Cohen's d = 1

What is the constant of variation for the quadratic variation? x 2 3 4 5 6 y 32 72 128 200 288

cluponka [151]

We use different models for different types of variation. For example, linear variation is associated with the formula y=ax, or the more familiar y=mx+b (the equation of a straight line). Cubic variation: y=a*x^3. In the present case we're discussing quadratic variation; perhaps that will ring a bell with you, reminding you that y=ax^2+bx+c is the general quadratic function. Now in y our math problem, we're told that this is a case of quadratic variation. Use the model y=a*x^2. For example, we know that if x=2, y =32. Mind substituting those two values into y=a*x^2 and solving for y? Then you could re-write y=a*x^2 substituting this value for a. Then check thisd value by substituting x=3, y=72, and see whether the resulting equation is true or not. If it is, your a value is correct. But overall I got 16!

When we evaluate a logarithm, we are finding the exponent, or power x, that the base b, needs to be raised so that it equals the argument m. The power is also known as the exponent.

$5^2 = 25 \to \log_5(25) = 2$
