Answer:
The absolute value is always positive no matter if there's a negative.
Step-by-step explanation:
Notice, the volume of the area to be gravelled is just length*width*height.
the length is 2miles, there are 63360 inches in a mile so (2*63360) inches then.
the width is 35 feet, there are 12 inches in a foot, so (12 * 35) inches then.
the height is just 3 inches.
so the volume is (2*63360)(12*35)(3), or 159667200 inches.
now
how many yd³ is there in 159667200 in³?
Answer:
Largest angle is 84
Step-by-step explanation:
Let the smallest angle be x, ATQ, x+x+x+36=180, 3x+36=180, x=48
Mean = (5+6+4+6+4)/5 = 25/5 = 5
answer
mean = 5
The confidence interval for the mean usage of water is (18.7,20.5).
Given population standard deviation of 2.4, mean of 19.5 gallons per day and confidence interval of 98%.
We have to find the confidence interval for the mean usage of water.
To find out the confidence interval we have to first find margin of error.
μ=19.5
σ=2.4
α=0.98
α/2=0.49
We have to find the z value for the p value 0.49 which is z=2.33
Margin of error=z*μ/
=2.33*19.5/
=0.82
lower level=mean -m
=19.5-0.82
=18.68
after rounding upto 1 decimal
=18.7
upper mean = mean+m
=19.5+0.82
=20.52
Hence the confidence interval for the usage of water is (18.7,20.52).
