After solving an equation in Point Slope Form, you're directly given the slope intercept form which is y=mx +b
Find the median of this data
21+23+60+60+50+54+54+59+26+15+43+15=480/ 12 = 40
Now the median should be 50 so take 50 - 40 = 10
The missing number from the data is 10
I'll do the first three problems to get you started
=====================================================
Problem 40
Plug in x = 0 to find the y intercept
x+y = 5
0+y = 5
y = 5 is the y intercept
Plug in y = 0 to find the x intercept
x+y = 5
x+0 = 5
x = 5 is the x intercept
------------
<h3>Answer: The x intercept is 5. The y intercept is 5.</h3>
=====================================================
Problem 41
Use the same idea here as well
Plug in x = 0 to get
x-y = 5
0-y = 5
-y = 5
y = -5 is the y intercept
Now plug in y = 0 to solve for x
x-y = 5
x-0 = 5
x = 5 is the x intercept
------------
<h3>Answer: The x intercept is 5. The y intercept is -5.</h3>
=====================================================
Problem 42
Plug in x = 0 and solve for y
3x+4y = 12
3(0)+4y = 12
0+4y = 12
4y = 12
y = 12/4
y = 3 is the y intercept
Plug in y = 0 and solve for x
3x+4y = 12
3x+4(0) = 12
3x+0 = 12
3x = 12
x = 12/3
x = 4 is the x intercept
------------
<h3>Answer: The x intercept is 4. The y intercept is 3.</h3>
Answer:
(11, 0)
Step-by-step explanation:
to find the y intercept, set y to 0.
60x + 55y = 660
60x + 55 * 0 = 660
60x = 660
60x/60 = 660/60
x = 11
y intercept is (11, 0)
Answer:
The best estimate of the proportion of adults who say that the law goes easy on celebrities is 0.7435.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
In this question:
CI is between 0.645 and 0.842. So the best estimate of the proportion is:
(0.645+0.842)/2 = 0.7435
The best estimate of the proportion of adults who say that the law goes easy on celebrities is 0.7435.
