Answer:
πr2h
Step-by-step explanation:
Answer:
Proportion = 0.6 or 60 %
Step-by-step explanation:
Given:
- The obtained 95% confidence interval of a sample of adults rooting for North High:
(0.52 , 0.68)
- Sample size n = 150
Find:
What proportion of the 150 adults in the survey said they were rooting for North High School?
Solution:
The proportion of adults rooting for North high corresponds to the mean value of interval, as follows:
Proportion = ( 0.52 + 0.68 ) / 2
Proportion = 0.6 or 60 %
Answer: k=143
Step-by-step explanation:
Let's start with the standard form of a linear equation: y = mx + b, where m ios the slope and b is trhe y-intercept (the value of y when x=0). We know the slope, so:
y = -15x + b
We can find the y-intercept, b, by using the one given point (6,-7) in the equation and solve for b:
y = -15x + b
-7 = -15(6) + b
-7 = -90+b
b = 83
The equation is y = -15x + 83
Use the x value of (-4,k) to find y, which will be k.
y = -15x + 83
y = -15(-4) + 83
y = 60 + 93
y = 143
k is 143
