Answer:
p = 16
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
24p = 384 ( divide both sides by 24 )
p = 16
Answer:
Stop the line of production since the sample mean (56.96) is outside the confidence interval [ = ( 56.98, 57.05 )]
Step-by-step explanation:
Given that;
95% confidence interval for these parts is 56.98 to 57.05
= ( 56.98, 57.05 )
Sample mean = 56.96
We know that;
If the sample mean is within the confidence interval then, our decision is to keep the line operating as it is inside the confidence interval.
But if the sample mean is not within the confidence interval them, our decision is to stop the line of production as it is outside the confidence interval.
Now since our mean sample (56.96) does not lie between with the 95% confidence interval = ( 56.98, 57.05 ).
Therefore, Stop the line of production since the sample mean (56.96) is outside the confidence interval [ = ( 56.98, 57.05 )]
The first step in solving this problem is to compute for the
area of the rectangular wall. The formula in computing the area of a rectangle
is:
A = LW
Substituting the given measurements in the problem to the
formula:
A = 13 (12)
A = 156
Therefore, the area of the wall is 156 square feet. To compute
the wallpaper cost of the wall, you have to multiply the cost per square foot
to the total area.
$8 per square foot x 156 square feet = $1,248
Therefore, the wallpaper cost for the wall is $1,248
Answer: 60 inches
Step-by-step explanation:
Let x be the height of son in the beginning of the year.
If the height is increased 110% at the end of the year , then his height in the end of the year = 110% of x
[since 110%=1.1]
Since, his height at the end of the year = 66 inches
Hence, the height of Mrs. Peters son in the beginning of the year is 60 inches.
