Ther will be 40 eights. Hope this helps!
Answer: A. 5%
Step-by-step explanation:
Given : The chance that they will join the graduate program : p=0.10
The total number of students in the class: n = 400
For this binomial situation :

We assume that this is normal distribution.
Let X be the random variable that represents the students will be joining a graduate program.
Z-score : 
For x= 50 , we have

Using the standard normal distribution table , we have

Hence, the value i.e.closest to the probability that at least 50 students will be joining a graduate program = 5%
The require degenerative circle is (x - 5)² + (y - 1)² = 0. Option C is correct.
Given that,
The equation for the degenerative circle is to be determined.
<h3>What is a circle?</h3>
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.
The degenerative circle is a circle whose radius is zero, from the option,
Option C has the equation of the circle with radius zero.
Thus, the required degenerative circle is (x - 5)² + (y - 1)² = 0.

Answer:
$17.12
Step-by-step explanation:
First let's find the normal cost with tax
7/100*19=133/100=$1.33
$19+$1.33=$20.33
Now we find the cost with tax for the Valentine's Day price
7/100*35=$2.45
$35+$2.45=$37.45
Now we subtract the normal cost from the Valentine's Day price
$37.45-$20.33=$17.12
96 pints, because 1 gallon equals 8 pints, so 12 X 8 equals 96.
