540 divided by 12 = y
Answer:
First picture: 60
Second picture:
Step-by-step explanation:
The first step for the first picture is to find the area of the triangle on top. In order to do that, we have to use the equation: (W*L*1/2)
(3*4*1/2)=6
Then, we multiply the above equation by the Height. Which makes the equation become 60.
The first step for the second picture is the same. We first find the area of the triangle on top.
(12*9*1/2)=54
Then we multiply the height by our above answer.
(54*20)=1,080
The other measurements that were there aren't needed. So, next time, completely ignore them!
Hope you have a good day/night! Good luck!
Answer:
You have to add up all the numbers then divide them by 3 and you will get your answer:
91+95=186 186+88=274
274÷3=91.333333333 etc.
then you add 90 to 27540
274+90=364
and because there are 4 tests you divide 364 by 4
364÷4=91
Your Answer-91
sorry answer is late!
No, any one of the 10 mayflies in the group live for 1 full day.
The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations and their mean.
The life spans of 10 adult mayflies have a mean of 4 hours and a MAD of 2 hours.
Fill in the table below with possible values for the life spans. You can use the same values more than once.
Mean = 4 hours.
Mean absolute deviation = 2 hours.
Assume that the life spans of each fish is 4 hours;
Then mean = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4/10
= 40/10
= 4 hours.
No fish can live for a full day.
Hence, No, any one of the 10 mayflies in the group live for 1 full day.

Step-by-step answer:
Assuming MAD stands for mean absolute deviation (2 hours), then the total absolute deviation from the mean (4 hours) is 10*2=20 hours.
If one of the flies live for 1 full day, the absolute deviation is 24-4=20 hours. This automatically requires the other flies live exactly 4 hours to have the MAD equal to 20 hours.
However, the above arrangement does not give a mean of 4 hours, but a mean of (24+9*4)/10=6 hours. This means that it is not possible to have a fly living for a full day.
Step-by-step explanation:
To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius. To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.
