THE ANSWER IS 4pi


The volume of a sphere is calculated using the formula 4pi r^3/3=32pi/3. Solve for r and get r=2. Then plug into the formula for finding the area of a circle A=r^2pi so you get 4pi.

The first step in the process for factoring the trinomial x2-3x - 40
Alexxx [7]
We need two numbers that when multiplied will give you -40 and when added will give you -3:
(x+5) (x-8) this is your answer. And you want to know the process Here it goes. And attached is a chart I made you so you can visually see what this process is telling you:
1) identify a,b, and c in the trinomial ax^2 + bx+c (in your case it's 1x^2-3x-40= x^2-3x-40)
2) write down all factor pairs of c (numbers that multiplied produce -40)
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials

Use the following prompt to answer the next 6 questions. Suppose we want to test the color distribution claim on the M&M’s w
vitfil [10]

Answer:

The claim on the M&M’s website is not true.

Step-by-step explanation:

A Chi-square test for goodness of fit will be used in this case.

The hypothesis can be defined as:

<em>H</em>₀: The observed frequencies are same as the expected frequencies.

<em>Hₐ</em>: The observed frequencies are not same as the expected frequencies.

The test statistic is given as follows:

\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}

Here,

O_{i} = Observed frequencies

E_{i}=N\times p_{i} = Expected frequency.

The chi-square test statistic value is, 14.433.

The degrees of freedom is:

df = <em>k</em> - 1 = 6 - 1 = 5

Compute the <em>p</em>-value as follows:

p-value=P(\chi^{2}_{k-1} >14.433) =P(\chi^{2}_{5} >14.433) =0.013

*Use a Chi-square table.

The significance level is, <em>α</em> = 0.05.

p-value = 0.013 < <em>α</em> = 0.05.

So, the null hypothesis will be rejected at 5% significance level.

Thus, concluding that the claim on the M&M’s website is not true.
