Answer:
Confidence interval = 48±4
Step-by-step explanation:
Given:
Mean X = 48
Standard deviation sd = 14.1
Computation:
Z table value of 90% = 1.645
Total number n = 33
Computation:
Margin of error M.E = Z[sd/√n]
Margin of error M.E = 4 approx.
Confidence interval = 48±4
I believe that the answer to this question would be 2(12a + b^3). Wait for someone else for clarification. :)
Do you have the problem for the linear equations
40 feet long but i not positive i will returned in one second
First write down the formula which is: y=mx+b
M is the slope and B is the y-intercept
The slope is rise/run, so if your slope is 2 then, 2 is your rise and 1 is your run
In order to find the y intercept you have to plot the points given in your question and and move your rise down and moving the run to the left until you find your y-intercept
Once you find the y-intercept, just plug in your slope and y-intercept
