This is in slope-intercept form, y=mx+b. m is the slope (b is the intercept). So the slope here is 8.
50(3/4) is 37.5
35 is less than 37.5, and if 35 states approve the amendment, the constitution will not be amended.
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.
Answer:
x = -5 or x = -12
Step-by-step explanation:
x^2+17x+72=12
Subtract 12 from both sides.
x^2+17x+72-12 = 12-12
x^2+17x+60=0
Then factor the left side of the equation
(x+5)(x+12) = 0
Then set the factors equal to 0
(x+5)=0 or (x+12)=0
Therefore x=-5 or -12
Answer:
19
Step-by-step explanation:
20 subtract 1 equals 19
