Mathematics
1 answer:
natali 33 [55]3 years ago

Answer:

OPtion B

Step by step explanation:

Lets plug in a random value for x.

Lets say 5 is x

-8(-5-5)=(y+1)^2

5-5 = 0

-8(0) = 0

0 = (y+1)^2

Square root of both sides

0 = y+1

subtract one from both sides

-1 = y

that means the x is 5 and the y is -1. Option B illustrates exactly that!

It won't. Both are increasing by 1.5 every year. If you graph that, the lines will be parallel. Parallel lines have no intercept.

Vilka [71]

Answer:

A)σ_M = 1.2634

B) CI = (36.564, 41.516)

C) σ_M = 0.1151

Step-by-step explanation:

A) Formula for standard error is;

σ_M = σ/√n

We are given;

Mean; x¯ = 39.04

Standard deviation; σ = 11.51

Sample size; n = 83

Thus;

Standard error; σ_M = 11.51/√83

σ_M = 1.2634

B) formula for confidence interval is;

CI = x¯ ± z(σ_M)

z is critical value

At 95% Confidence interval, z = 1.96

Thus;

CI = 39.04 ± 1.96(1.2634)

CI = (39.04 + 2.476) and (39.04 - 2.476)

CI = (36.564, 41.516)

C) sample size is now increased to 10000

Thus,standard error is calculated as;

σ_M = 11.51/√10000

σ_M = 0.1151
