Answer:
30 pages a hour
Step-by-step explanation:
1.5 every 3 minutes
there is 60 minuts in an hou you already have 3 so thimes it by 20 to get 60 then times 60 by 1.5
1. 3x - 3y = 9
to find the x or y intercept, multiply the other variable that you are not tryng to find by 0
3x - 3(0) = 9 3(0) - 3y = 9
3x = 9 -3y = 9
3x/3 = 9/3 -3y/-3 = 9/-3
x = 3 y = -3
2. I did the same thing for the rest
x = 6 y = -2
3. x = 2.5 y = -5
4. x = -4 y = -2/3

Step-by-step explanation:
Please find the correct question in the attached file:
The formula for calculating the Confidence interval of proportion:
The number of learners with access to working at home on a computer:
Lower limit =0.48
upper limit = 0.60
The sample std. dev. will be (14 inches) / sqrt(49), or (14 inches) / 7, or 2 inches.
Find the z score for 93.8 inches:
93.8 inches - 91.0 inches 2.8 inches
z = ------------------------------------- = ----------------- = 1.4
2 inches 2 inches
Now find the area under the standard normal curve to the left of z = +1.4.
My calculator returns the following:
normalcdf(-100,1.4) = 0.919. This is the probability that the mean annual precipitation during those 49 years will be less than 93.8 inches.
