Answer:
0.05x+0.25y=8.75; the y intercept represents that if she found 0 nickels she must have found 35 quarters.
Step-by-step explanation:
1. Solve for y:
0.25y= 8.75-0.05x (subtract 0.05x on both sides)
y= (8.75-0.05x)/0.25 (divide by 0.25 on both sides)
2. Since the y intercept can be found when x equals 0, plug in 0 for x into the equation.
y=(8.75-0.05(0))/0.25
y= 8.75/0.25
y=35
The right answer for the question that is being asked and shown above is that: "D.) There is likely an association between the categorical variables because the relative frequencies are both close to 0.50." Given that a relative frequencies of 0.48 and 0.52, there will be an association between the categorical variables.<span>

Answer:
The measure of the exterior angle is 92 degrees
Step-by-step explanation:
Problem 16)
we know that
An exterior angle of a triangle is equal to the sum of the opposite interior angles
so
In this problem
solve for x
Find the measure of the exterior angle
Let's denote students in D = in the drama club , S<span> = in a sports team </span>
<span>P(D) = 85/330 </span>
<span>P(S) = 200/330 </span>
<span>
P(D and S) = 60/300 </span>
<span>
P(D or S) = P(D) + P(S) - P(D and S) </span><span>= 85/330 + 200/330 - 60/330 = 15/22 </span>
<span>
P(neither D nor S) = 1- 15/22 </span><span>= 7/22</span>
