So, first you want to have 113 then you are going to want to divide it by pi or 3.14. After that, square it.

Your answer would be 6

Simplify (1/4 ad^3)^2

Dima020 [189]

That "ad^3" bothers me; I'm not sure what you mean here.

I'm going to assume that you have (1/4*a*d^3)^2.

If that's the case, then you have (1/4)^2 * a^2 * d^6 = (1/16)*a^2*d^6.

If this is not what you were hoping for, double check to ensure that you have copied down this problem exactly as it was presented.

Use the factor theorem to determine whether the binomial x + 1 is a factor of the polynomial function ƒ(x) = 2x3 – 9x2 + 13x – 6

Andrews [41]

No, it is not.
If x+1 is a factor, x=-1 would be one of the zeros.
Plug x=-1 in the polynomial to see it is results in a 0:
2(-1)^3-9(-1)^2+13(-1)-6=-30≠0, therefore, x+1 is not a factor.

A researcher analyzed the results of her data from 30 subjects and calculated the variance of scores at 113.00. What is the stan

Alla [95]

Answer:

10.63

Step-by-step explanation:

Data provided in the question

Data = 30 subjects

The Variance of scores = 113.00

The calculation of standard deviation is shown below:-

As we know that

Variance = Standard deviation^2

Therefore,

Standard deviation = $\sqrt{variance}$

= $\sqrt{113}$

= 10.63

Therefore for computing the standard deviation we simply applied the above formula.
