Answer:

28%

Step-by-step explanation:

So I am assuming the numbers are the number of students.

So 64 + 28+ 52 +56 = 200 students

Assuming the 56 outside the diagram are NOT attending either college.

so 56/200 =28%

How do you solve an absolute value equation?

Mkey [24]

The distance between two real numbers $x,y$ is the absolute value of their difference, $|x-y|$ . So the statement "all $x$ that are 1/4 away from -6" is captured in the equation

$|x-(-6)|=\dfrac14$

$|x+6|=\dfrac14$

To solve, you can use the definition of absolute value: if $x$ is not negative, then $|x|=x$ ; otherwise, $|x|=-x$ .

So there are two cases to consider:

1. Suppose $x+6\ge0$ . Then $|x+6|=x+6$ , and the equation reduces to

$x+6=\dfrac14\implies x=-\dfrac{23}4$

2. Suppose $x+6$ . Then $|x+6|=-(x+6)=-x-6$ and

$-x-6=\dfrac14\implies x=-\dfrac{25}4$

$-6=-\dfrac{24}4$ , so the two solutions we found are correct because both $-\dfrac{23}4$ and $-\dfrac{25}4$ are indeed 1/4 away from -6.

- - -

For the question regarding inequality, you know that the absolute value must return a non-negative number. In other words, there is no $x$ such that $|x|$ .

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,
$P(X=x)=nC_xp^x(1-)^{n-x} [\tex] To find the probability that 3 out of the 5 Senators will support the tax proposal is [tex] P(X= 3)=5C_3(0.25)^3(1-0.25)^{5-3}\\ =0.08789$
