Answer:

A = 78.5 in ^2

Step-by-step explanation:

Area of a circle = pi * r^2

The radius is d/2

r= 10/2

r =5

A = pi * r^2

Substitute r=5

A = pi *(5)^2

A = 25 pi

We know that pi is approximated by 3.14

A = 25 (3.14)

A = 78.5 in ^2

A state senator believes that 25% of all senators on the finance committee will strongly support the tax proposal she wishes to

sp2606 [1]

$P(X=x)= nC_xp^x(1-p)^{n-x}$ Number of Senators be n=5
Probability that the Senators will strongly support the tax proposal be $p=\frac{25}{100}=0.25$
Let X be the number of Senators will strongly support the tax proposal.
Using Binomial Distribution,
$P(X=x)=nC_xP^x(1-p)^{n-x}$
Now Plug in the values of n and p,
$P(X=x)=nC_xp^x(1-)^{n-x} [\tex] To find the probability that 3 out of the 5 Senators will support the tax proposal is [tex] P(X= 3)=5C_3(0.25)^3(1-0.25)^{5-3}\\ =0.08789$
