Answer:
-365
Step-by-step explanation:
-3x+7(-6-50)
- -3(-9)+7(-6-50)
- 27+7(-6-50)
- 27-42-350
- -15-350
- =-365
Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.
Step-by-step explanation:
Definitions:
- Null hypothesis
is a statement describing population parameters according to the objective of the study. It takes "≤,≥,=" signs.
- Alternative hypothesis
is a statement opposite to the null hypothesis elaborating population parameters according to the objective of the study. It takes ">, <, ≠" signs.
Given: The diameter of a spindle in a small motor is supposed to be 5.8 millimeters.
If the spindle is either too small or too large, the motor will not work properly. so, Mean diameter ≠ 5.8 to work correctly.
i.e. 
So, 
The required null and alternative hypotheses:
H0: Mean= 5 and Ha: Mean is not equal to 5.
First you multiply 2.20 and 2.5 which gives you 5.5, then you multiply 2.20 and 1.2 which gives you 2.64, after the multiplying, you add your totals (5.5 + 2.64) and that equals 8.14. So he spent a total of $8.14 on apples.
HL is the radius which is half of the diameter....lso 24/2 = 12
r = 1/2(121) is the answer for this one since radius is 1/2 of the diameter
Answer:
p ≤ 10
Step-by-step explanation:
3/5 * p ≤ 6
Multiply each side by 5/3
5/3 *3/5 * p ≤ 6* 5/3
p ≤ 10
