Answer:
The answer is
2.451
Step-by-step explanation:
52% oppose making all US colleges free
Total population n = 600
X = 342 people who supports taxpayer funded free college
P = 0.52
N = 600
P^ = x/n
= 342/600
= 0.57
Test statistic
Z = ^p-p/√p(1-p)/n
Z= 0.57-0.52/√0.52(1-0.52)/600
Z = 0.05/√0.000416
Z = 0.05/0.020496
Z = 2.451 or 2.45
That is the value of the test statistic.
Answer:
The scale factor is -1/4.
Step-by-step explanation:
Answer:
Step-by-step explanation:
r=12
circumference of arc = theta/360*2πr=3π given
Pi cancels
theta/360*2*12=3
theta*6/90=3
theta*3/45=3
3 cancels,45 to the other side
theta=45 degrees
This should do it :)
Answer: y = 5(x - 3)² - 2
<u>Step-by-step explanation:</u>
Vertex form: y = a(x - h)² + k <em>where (h,k) is the vertex and "a" is the vertical stretch</em>
Given (h, k) = (3, -2) and (x, y) = (2, 3), we can find the a-value.
3 = a(2 - 3)² - 2
3 = a(1) - 2
<u>+2</u> <u> +2 </u>
5 = a
Next, input the vertex and the a-value into the vertex equation.
y = 5(x - 3)² - 2
Answer:
167.64
Step-by-step explanation:
- To evaluate the tax add on, divide 149.99 by 8.5 which divided and rounded is 17.65
- add 17.65 and 149.99
