Your slope is -2 for every 5 and your y intercept is 2
Answer:
95% Confidence interval for y
= (-9.804, -5.979)
Lower limit = -9.804
Upper limit = -5.979
Step-by-step explanation:
^y= 2.097x - 0.552
x = -3.5
Standard error = 0.976
Mathematically,
Confidence Interval = (Mean) ± (Margin of error)
Mean = 2.097x - 0.552 = (2.097×-3.5) - 0.552 = - 7.8915
(note that x=-3.5)
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error of the mean)
Critical value for 95% confidence interval = 1.960
Standard Error of the mean = 0.976
95% Confidence Interval = (Mean) ± [(Critical value) × (standard Error of the mean)]
CI = -7.8915 ± (1.960 × 0.976)
CI = -7.8915 ± 1.91296
95% CI = (-9.80446, -5.97854)
95% Confidence interval for y
= (-9.804, -5.979)

Answer:

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
the mean increase and median decreases
In similar figures the statement is written in such a way so that corresponding sides and equal angles are placed at same place .
The given similarity statement can be written as KLMN ~ PQRS
The question is asking us to find the angle which corresponds to <N
In the statement N occurs at the last place in the letter KLMN so we will look at the same place in the letter PQRS,
The letter S occupies the same place as N
So we say <N corresponds to <S
The first option is right
