Answer:
A 23 of people who prefer plan 1 are from the 35-45 age group and 42% of people from the 46-55 age group prefer plan 2.
Step-by-step explanation:
add everyone who prefers plan 1 = 60
age 36-45 / total of plan 1 = 14/60 = .23 or 23%
add everyone in age group 46-55 = 50
in age group 46-55 and prefers plan 2 = 21 / 50 = 0.42 or 42%
Answer:
The p-value of the test is 0.2.
Step-by-step explanation:
Using the alternative hypothesis that µ ≠ 531, Amy found a t-test statistic of 1.311.
Alternative hypothesis means that e have a two-tailed hypothesis test.
Sample 30 citizens. Amy found a t-test statistic of 1.311.What is the p-value of the test statistic?
Thus, we have a two-tailed test with 30 - 1 = 29 degrees of freedom and t = 1.311. So, using a t-distribution calculator, the p-value of the test is 0.2.

198 cubic meters
7300-5500=1800 needs to come from salespeople. To make at least 7300, the salespeople need to make at least 1800, which means:
300 x number of people >= 1800
Number of people >= 6
C is correct
The midpoint of a line segment divides the line segment into equal halves.
- The value of x is 4
- The value of VM and MW is 15
- The value of VW is 30
Point M is the midpoint of line segment VW.
So, we have:
Substitute known values
Collect like terms
Evaluate like terms
Hence, the value of x is 4
The expression for VM is:
So, we have:
Hence, the value of VM and MW is 15
The length of VW is the sum of both lengths.
So, we have:
Hence, the value of VW is 30
