Answer:
Option C is correct.
The test statistic for this question is -3.13
Step-by-step explanation:
To compute the z-test statistic, the formula is given as
z = (x - μ₀)/σₓ
x = p = sample proportion of the 500 college students sampled, that favor reducing the deficit using only spending cuts with no tax increase = (75/500) = 0.15
μ₀ = p₀ = the proportion to be compared against, that is, the proportion of Americans that favor reducing the U.S. budget deficit by using spending cuts only, with no tax increases = 20% = 0.20
σₓ = standard error of the sample proportion = √[p(1-p)/n]
p = 0.15
n = Sample size = 500
σₓ = √[0.15×0.85/500] = 0.01597
z = (0.15 - 0.20) ÷ 0.01597
z = -3.13

Answer:
The answer would be: D. (1,2) and (2,-1)
Answer:
h=1.27 in.
Step-by-step explanation:
V=πr^2h
Plugin the values and solve
36=π(3)^2h
36/9π=h
h=1.27323954
Answer:
Step-by-step explanation:
Are the sides consistent with the Pythagorean Theorem?
6² + 8² ≟ 9²
36 + 64 ≠ 81, so it is not a right triangle.
Answer:
Equation of line through () having undefined slope is given by
where α =90°
Now ,it is given that line passes through (97, 93)
So , equation of line is
→ = tan 90°
As, tan 90°=1/0
→ (x-97)×1= (y-73)×0
→ x-97 =0
→ x=97 , which is the required equation of line.
