Answer:
D-70.81
Step-by-step explanation:
I did the math, this should be correct.
Good luck!
(a) since we are given that f(8) = 9, the inverse of 9 is simply 8. Therefore, f^-1(9) = 8.
(b) Again, f is the inverse of f^-1, therefore, you simply switch numbers, and you get that f(-3) = -7.
Y = 3bx - 7x
y = x(3b - 7)
Divide each side by 3b - 7 (assume that it is not zero).

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!!!
Answer:
Apply BODMAS
Step-by-step explanation:
PLEASE FIND THE PICTURE BELLOW
SOLUTION STEPS
(4⋅2−10x−24)(2x+3)
Multiply 4 and 2 to get 8.
(8−10x−24)(2x+3)
Subtract 24 from 8 to get −16.
(−16−10x)(2x+3)
Apply the distributive property by multiplying each term of −16−10x by each term of 2x+3.
−32x−48−20x
2
−30x
Combine −32x and −30x to get −62x.
−62x−48−20x
2
