Answer:
Zero of the function;
f(x) = 0 at x = -1.333
Discontinuity;
x = 1
Step-by-step explanation:
To determine the zero of the function;
we simply graph the function as shown in the attachment below.
From the attachment, we can deduce that f(x) = 0 at x = -1.333
To determine the discontinuity or the undefined points of the function, we simply equate the denominator to 0 and solve for x;
x - 1 =0
x = 1
The function is therefore not defined at the point where x =1
For 12 number of shirts would the cost be the same
<u>Solution:</u>
Given, Some students want to rider shirts with their school logo.
Let the number of shirts taken be "n"
One company charges $9.65 per shirt plus a setup fee of $43.
⇒ Total cost = 9.65n + 43
Another company charges $8.40 per shirt plus a $58 setup fee.
⇒ Total cost = 8.4n + 58
We have to find for what number of shirts would the cost be the same?
So, we have to equate both the total costs
Hence, students has to take 12 shirts for the cost to be same
Part A:
Given that in a sample of 400 registered voters, 204 were democrats, i.e. n = 400, <span>
</span>The 95% confidence interval for the proportion of registered democrats voters in the population is given by:
Part B:
Given that t<span>here
are 169 million registered voters in the US, the interval for
the number of registered democrats in the population is given by
[0.461(169,000,000), 0.559(169,000,000)] = (77,909,000, 94,471,000)

Answer:
376.8
Step-by-step explanation:
There are a lot of moving parts. We need to find the area of the bottom of the circle the center and the top circle.
The top and the bottom will be the same.
The area of a circle:
a =
a = 3.14()
a = 3.14(25)
a =78.5
The center: Think of this as a label on soup can. If you tear the label off it would be a rectangle. To find the area we would multiply the height of the can by the circumference of the circle. They tell us the height is 7 and we can calculate the circumference.
C = d The d is the diameter it is 2 of the radiuses.
C = 10
C = 3.14(10)
C = 31.4
Now we multiply 31.4 and 7 together to find the area of the center of the cylinder.
(31.4)(7) = 219.8
The total area:
top 78.5
center 219.8
bottom 78.5
Total 376.8
C0 x=10. you set the two equal to each other and solve.
