<span>The sash needs to be 184.912 cm. to equal 72.8 in.</span>
Answer:
Step-by-step explanation:
The larger the sample size, the lower the standard deviation. The standard deviation shows how the data is spread from the mean. Therefore, benefit of increasing the sample size when trying to estimate the mean from a sample average are
a. A reduction in the bias of the estimate.
b. A reduction in the variability of the estimate.
The width of confidence interval is determined by the margin of error
Margin of error = z × s/√n
A smaller standard deviation and increased size would result to a narrower confidence interval. Therefore, increasing the sample size does not result to an increase in the width of the resulting confidence interval.
-7x+14>-3x-6
Add 3x to both sides
-7x+14+3x>-3x-6+3x
-4x+14>-6
Subtract 14 from both sides
-4x+14-14>-6-14
-4x>-20
Divide both sides by -4
-4x/4>-20/-4
x<5

Answer:
<em>x∈ -10,4</em>
Step-by-step explanation:
x+3<7, x+3≥0: -(x+3)<7, x+3<0- separate the inequality into 2 possible cases
x<4, x≥-3; x>-10, x<-3- solve the inequalities
x∈ [-3,4}; x∈ {-10,-3}- find the intersection
x∈{-10,4}- Find the union
