Find the perimeter of this shape

1 answer:

Margaret [11]3 years ago

4 0

The answer is 257.08m. Explanation: you know that one side of the square in the middle is 50m. This is the same as the diameter of one of the half circles on each side. The perimeter of a circle is the formula C=2(pi)r, where r is the radius. Dividing 50 by two will get you the size of the radius, then just plug it into the equation to find the perimeter of both rounded sides (a full circle). The two circular sides equal 157.08m, so then you just need to add the flat sides, which are both 50m since they’re congruent. 157.08m + 50m + 50m = 257.08m, so the perimeter of the shape is 257.08m.

A commonly used IQ test is scaled to have a mean of 100 and a standard deviation 15. A school counselor was curious about the av

Licemer1 [7]

Answer: (103.74,112.06)

Step-by-step explanation:

The confidence interval for population mean is given by :_

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size : n= 50

Sample mean : $\overline{x}=107.9$

Standard deviation : $\sigma=15$

Significance level : $\alpha: 1-0.95=0.5$

Critical value : $z_{\alpha/2}=1.96$

Then the 95% confidence interval for the student IQ in the school will be :-

$107.9\pm (1.96)\dfrac{15}{\sqrt{50}}\\\\\approx107.9\pm0.075\\\\=(107.9-4.16,107.9+4.16)=(103.74,112.06)$

Hence, the 95% confidence interval for the student IQ in the school= (103.74,112.06)

What is the surface area of the breadbox

kozerog [31]

Answer:

Step-by-step explanation:

surface area of two sides=2[(8×8)+π×8²/4]

=2[64+16π]

=128+32π

surface area of curved surface=2πrh/4

surface along length=base (16×16)+2×(16×8)+2×π×8/4 ×16

=256+256+64π

=512+64π

Total surface area=128+32π+512+64π

=640+96π

≈640+302

≈942 in²
