Answer:
4/75
Step-by-step explanation:
you will get 5 and 1/3 percent equals (5 + 1/3) / 100 which is equal to 5/100 + (1/3) / 100 which is equal to 5/100 + 1/300. place both fractions under a common denominator. you will get 5/100 + 1/300 = 15/300 + 1/300 = 16/300. simplify the fraction to get 16/300 = 8/150 = 4/75
Answer:
Step-by-step explanation:
Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H0: p1 - p2=0
Ha: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575
See the attached photo for the calculations for this test
Slope = (y2 - y1)/(x2 - x1) = (-1 - 4)/(4 - (-3)) = -5/(4 + 3) = -5/7
Answer:
Length of 6 feet
Width of 2 feet
The estimate of the perimeter of the countertop is 16 feet.
Step-by-step explanation:
Rectangle:
A rectangle has two dimensions: The length(l) and the width(w). The perimeter of a rectange is:
P = 2(l + w).
In this question:
Length: 5.75 feet
Width: 2.47 feet.
Round the length and width to the nearest whole number .
5.75 is closer to 6(0.25) than to 5(0.75). So the length is 6 feet.
2.47 is closer to 2(0.47) than to 3(0.53). So the width is 2 feet.
Then estimate the perimeter of the countertop
P = 2(l + w) = 2(6 + 2) = 16
The estimate of the perimeter of the countertop is 16 feet.
