Answer:
Y-Intercept is always gonna be on the Y axis.
5x + 9x + 26 = 180
14x = 180 - 26
14x = 154
x = 154 / 14
x = 11
answer
B. 11
Answer:
a: 105.2 < µ < 112.8
b: 104.872 < µ < 113.128
c: 105.841 < µ < 112.159
d: No, because n < 30
Step-by-step explanation:
For a - c, see attached photos for work. There are 2 formulas to use. The steps for constructing any confidence interval are the same, you will just use different numbers in the formula depending on what data is given to you.
d: With large sample sizes, the data often resembles normally distributed data, so we can still construct confidence intervals from the data.
So angles in a triangle add up to 180
Angle B is 50 and angle E is 90
90+50=140
180-140=40°(angle A)
Now the other triangle
Angle C is 62 and angle E is 90
90+62=152
180-152=28
40-28=12
hope this helped but I can't help with the second one
