For this one I'm going to assume that 4 7a means 4 * 7a...
(8 + 7a) + 4 * 7a =
8 + 7a + 28a =
8 + 35a
If I read it wrong and 4 7a is actually 47a then...
(8 + 7a) + 47a =
8 + 54a =
2(4 + 27a)

Answer:
The probability that 13 of them were very confident their major would lead to a good job is 1.08%.
Step-by-step explanation:
Given : A 2017 poll found that 56% of college students were very confident that their major will lead to a good job. If 15 college students are chosen at random.
To find : What's the probability that 13 of them were very confident their major would lead to a good job?
Solution :
Applying Binomial distribution,
Here, p is the success p=56%=0.56
q is the failure
n is the number of selection n=15
The probability that 13 of them were very confident their major would lead to a good job i.e. x=13
Substitute the values,
The probability that 13 of them were very confident their major would lead to a good job is 1.08%.
The easiest way to graph a line is in slope-intercept form. y=mx%2Bb
x-y=4
-y=-x%2B4
multiply by -1 because y must be positive
y=x-4
your slope of the line is 1
y-intercept is -4
The graph would look like:
Answer:
(x-5)^2 + (y+4)^2 =64
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-5)^2 + (y- -4)^2 = 8^2
(x-5)^2 + (y+4)^2 =64
