Answer:
150.8
Step-by-step explanation:
I helped lol.
Have a nice day! :-)
I can't write the symbol, but it would be X<30 and the <would have a horizontal line under it so that it would mean x is less than or equal to 30
Ur graph.....u have a line that has a y int of -2....it has a slope of 3....it has a solid line...so there is no equal sign...it is shaded above the line, so it is greater then.....y > = 3x - 2
u have another line that has a y int of 2....it has a slope of -1/2....it has a solid line...so there is an equal sign in the problem...it is shaded below the line...so it is less then....
y < = -1/2x + 2
1/2x + y < = 2...multiply by 2
x + 2y < = 4
so ur answer is : y > = 3x - 2 and x + 2y < = 4...the 2nd one
Given:
Sample proportion = 85% = 0.85.
Confidence level (CL) = 90%.
Confidence interval (CI)
We want the confidence interval to be 5% or 0.05. Therefore
Because this number is less than 1, a default sample size of 30 (for the normal distribution) is recommended.
Answer: 30
Answer:
D
Step-by-step explanation:
|C|<|D|
So C≠D
