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
Hope this Helps!!!
Therefore, the answer is 1) y = 2x - 6
Number of red cars = x
Number of white cars = y
x + y = 75
y + 3 = 2x
x + y = 75
y = 75 - x
(75 - x) + 3 = 2x
78 = 3x
26 = x
y + 3 = 2(26)
y + 3 = 52
y = 49
There are 49 white cars.
Solve for x by simplifying both sides of the equation then isolate the variable your answer is x=10.
Answer:
2. (3/6)/4 = 1/8
3. (1/3)/(1/4) = 4/3
Step-by-step explanation:
To solve these expressions, simply solve them by multiplying the reciprocal of the bottom number times the fraction in the numerator:
2. (3/6)/4
3/6 x 1/4
3/24
1/8
3. (1/3)/(1/4)
1/3 x 4
4/3
