Answer:
$450
Step-by-step explanation:
We know that the washer costs $51 more dollars than the dryer.
The washer costs x+51
The dryer costs x
So to simplify this we can do this equation:
2x+51=951
Substitute and simply the equation, and you should get this:
2x=900
x=450
Hope this helps! :)
First, see how much money you have:
10 + 3(5) + 8(1) + 12(0.25) + 5(0.1) + 10(0.05) =
10 + 15 + 8 + 3 + 0.5 + 0.5 =
37
You need to deposit $7 into the safe, since 37 - 7 = 30.
Answer:
Reject the null hypothesis.
Step-by-step explanation:
n1 = 16
n2 = 21
S.V1 = 5.8
S.V2 = 2.4
= 0.05
= Population Variance 1 ≤ Population Variance 2
= Population Variance 1 > Population Variance 2
Test statistic value = 5.8 / 2.4 = 2.417
Degrees of freedom is n - 1
15 and 20
Critical value is 
= 2.2
2.417 > 2.2
we reject the null hypothesis as the critical value is greater than the test statistic.
Answer:
✓ The data for store 1 shows greater variability.
✓ The mean of the data for store 1 is greater than the mean of the data for store 2.
9.65x1012 that is the answer
