Answer:
One-sample Z-test
Step-by-step explanation:
As the sample size is greater than 30, assuming the data is a simple random sample, and that the data has a normal distribution, the sociologist should conduct a one-sample z-test to calculate the p-value.
4(x-3)-2+2x=5(3x-7)-9x
4x-12-r+2x=5(3x-7)-9
4x-12-r+2x=15x-35-9x
6x-12-r=15x-35-9x
6x-12-r=6x-35
add 12 to -35 which equals -23.
add 6x+6x it cancels out to 0.
-r=-23
to make r positive just add it -23
since 23 is already negative it would become a positive because a negative + negative= positive
answer: r=23
M< 1 = 128, m< 2 = 26, and m< 3 = 26.
Answer:
B.)21.4
Explanation
A(-4, 3), B(0,2), C(2,4) and D(0,-3)
AB = √(1²+4²) = √17 =4.12
BC = √(2²+2²) = √8 = 2.83
CD = √(2²+7²) = √53 = 7.28
AD = √(4²+6²) = √52 =7.21
Perimeter = 4.12+2.83+7.28+7.21 = 21.44
To the nearest tenth the answer is 21.4.
