Answer:
Perimeter = 70ft
Step-by-step explanation:
Area of a rectangle is:
area = (length * width)
150 = a * b
a = 6b
a = length
b = width
then:
150 = 6b*b
150 = 6b²
b² = 150/6
b² = 25
√b² = √25
b = 5ft
a = 6b
a = 6*5
a = 30ft
then:
perimeter of a rectangle is:
p = 2(a+b)
p = 2(30 + 5)
p = 2*35
p = 70ft
Answer:
A. Reject H0 because the P-value is less than or equal to α.
Step-by-step explanation:
Decision:
If the pvalue of the test is less than the significance level, we reject the null hypothesis H0.
Otherwise, we fail to reject the null hypothesis H0.
In this question:
Significance level: 0.01
P-value: 0.0087
0.0087 < 0.01, so we reject H0.
The correct answer is given by option A.
Answer:
yyhyh
Step-by-step explanation:
Try graphing it to help, but since it's not a slanted line (because the y-values are the same), you just do x1-x2:
-3 - -7 = 4
