Answer:
Step-by-step explanation:
Given : Casey was at the surface of a swimming pool and recorded the following two measurements, in feet, on a number line: −8, which represents the depth of water in the swimming pool +7, which represents the height of the slide at the pool
To Find : What does 0 represent in this situation?
Describe the height of the slide in relation to 0 in the situation
Casey held a pole in the swimming pool. The bottom of the pole was at a depth of 2 feet. How should Casey mark the level of the bottom of the pole on the number line
Solution
0 represent in this situation - Top surface of Swimming pool - Surface matching with ground
height of the slide in relation to 0 in the situation = 7 feet
pole was at a depth of 2 feet = - 2
2x=$5.00
x=$2.50
3x=$7.50
x=$2.50
15x=
15(2.50)=$37.50
hope this helps!
Step-by-step explanation:
the base is 5unit and the height is 9unit
Answer:
We are given:
Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.
Since the alternative hypothesis has less than sign, therefore the given hypothesis is left-tailed
What parameter is being tested?
The parameter used is 
, which denotes the population mean.
Please note:
The type is test determined based on the alternative hypothesis.
If the alternative hypothesis has 
sign, it means the hypothesis test is two-tailed
If the alternative hypothesis has 
sign, it means the hypothesis test is right-tailed
If the alternative hypothesis has 
sign, it means the hypothesis test is left-tailed
Y=4 is going to be the answer.
