You need to use a ruler to measure each side of the shapes, then use the formula for area or perimeter to solve.
The gym teacher is 90% confident that the mean number of pushups the students can do in one minute is between 24.1 to 28.5
<h3>
Confidence interval</h3>
The confidence interval is given by:
Confidence interval = mean ± margin of error.
Given that the interval is 24.1 to 28.5, hence:
The gym teacher is 90% confident that the mean number of pushups the students can do in one minute is between 24.1 to 28.5
The length of the interval would increase if the confidence level were increased to 99%.

Answer:
Solar flux that incident on it is given as
S = 160 W/m/m
Now we know that the area of solar panels is given as
A = 10 m^2
So total solar power received by solar panels is given as
Power Received = (Solar flux) \times (Area)PowerReceived=(Solarflux)×(Area)
P = S\times AP=S×A
now here we have
P = 160 \times 10P=160×10
P = 1600 WP=1600W
now we know that efficiency of the solar panels is 20%
so total output power will be
efficiency = \frac{P_{out}}{P_{in}}efficiency=
P

P
out
0.20 = \frac{P_{out}}{1600}0.20=
1600
P

P_{out} = 320 WP

=320W
