Answer:
The 90% CI for p is (0.53, 0.83)
Step-by-step explanation:
We have to develop a 90% confidence interval for the proportion of all students at the college that have met with a counselor to develop an educational plan.
We have a sample of size 25, where the sample proportion is:
The critical value of z for a 90% CI is z=1.645.
The margin of error is then:
Then, the lower and upper bound of the confidence interval are:
The 90% CI for p is (0.53, 0.83)
Answer:
D and yes
Step-by-step explanation:
+ 1 = -3 If we multiply both sides of the equation by 4 will will get the second equation
(4) + (4) 1 = (4) -3
x + 4 = -12 We solve this for x by subtracting 4 from both sides.
x = -16
Plug -7 into both equations and you will see that it is a solution
+ 1 = -3
+ 1 = -3
-4 + 1 = -3
-3 = -3
x + 4 = =12
-16 + 4 = -12
-12 - -12
Answer:
y = -3x + 6

Step-by-step explanation:
Answer:
Area = 42 in^2
Step-by-step explanation:
here's your solution
=> divide above picture in two parts
=> rectangle and traingle
=> area of rectangle = length* width
=> area of rectangle = (5*6)in.
=> area of rectangle = 30 in^2
=> now, area of traingle = 1/2*base *height
=> area of traingle = 1/2*4*6
=> area of traingle = 12 in^2
=> area of figure = 30 in^2 + 12 in^2
=> Area = 42 in^2
hope it helps
