100% - 7% - 30% = 63% of people are on the sand
Answer:
Chantal and Trisha will have both traveled 105 miles in 20 minutes.
Step-by-step explanation:
is distance in miles, 
is time in hours.
The two equations are:
Set them equal to each other and solve for x:
Plug that back into the equations to confirm this gives the same :
The temperature was in the range of 10-13 on 7 of the days.
Give it the weight of the middle of the range = 11.5 for 7 times = 80.5
The temperature was in the range of 14-17 on 9 of the days.
Give it the weight of the middle of the range = 15.5 for 9 times = 139.5
The temperature was in the range of 18-21 on 16 of the days.
Give it the weight of the middle of the range = 19.5 for 16 times = 312
The temperature was in the range of 22-25 on 22 of the days.
Give it the weight of the middle of the range = 23.5 for 22 times = 517
The temperature was in the range of 26-29 on 6 of the days.
Give it the weight of the middle of the range = 27.5 for 6 times = 165
Total weight for all ranges = (80.5 + 139.5 + 312 + 517 + 165) = 1,214
Total number of days = 60
Estimated mean temperature = (1,214) / (60) = <u>20.23°C </u>

Answer with explanation:</h2>
We know that in statistics, the Type II error happens when the null hypothesis is false but fails to get rejected.
Given : The null hypothesis, 
, is: researchers claim that 65% of college students will graduate with debt.
Then , Type II error in this scenario will be when the researcher claim 65% of college students will graduate with debt is false but fails to be rejected.
Answer:
$2.34
Step-by-step explanation:
2.75 (the number of pounds) * 0.85 (price per pound) = 2.3375, or approximately 2.34.
