Answer:
You can sell at least 40 phones each week.
Step-by-step explanation:
Given that:
Weekly base salary = $150
Earning on each phone = $20
Maximum amount that can be earned each week = $950
Let,
m be the number of phones.
20m + 150 ≤ 950
20m ≤ 950 - 150
20m ≤ 800
Dividing both sides by 20
m ≤ 40
Hence,
You can sell at least 40 phones each week.
Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
Answer:
y=4x+3
Step-by-step explanation:
3 plus 4 is 7, 0 plus 1 is 1, so yeah, same slope and y-intercept is in a spot so the next point on the line is (1,7)
Given the equation :
So, to find d , divide both sides by ( -6 )
So,
Note: when we divide two negative numbers, the result will be a positive number
Well, you have to set up an equation.
You should know that length×width will give you the area.
length=2cm more than x (x+2)
width=5cm less than twice of x (2x-5)
so, the equation is (x+2)×(2x-5)=54
Now, just solve for x.
