Ok, so 11:9
11-9 = 2
which means that 124= 2:1
124/2 = 62
so 62:0
now 11 x 62= 682
9 x 62= 558
so the ratio is 682:558
now 682 + 558 = 1,240
There are 1,240 total students in the school. 682 boys and 558 girls
Answer:
Step-by-step explanation:
Okay first I will do is the mean.
73+77+85+84+37+115= 471
Then divid it by how many numbers. so, 6.
471 divided by 6 = 78.5
Mean is 78.5
~~~~~~~~~~
How to find the median
order them least to greatest.
37, 73, 77, 84, 85, 115.
The middle number is 77 and 84.
median: 80.5
mean: 78.5
Answer:
i dont know
Step-by-step explanation:
2v = <-10, 4>
4u = <-24, 4>
-4u = <24, -4>
-4u + 2v = <24, -4> + <-10, 4> = <14, 0>
To find the volume of a rectangular prism, we must multiply the length * width * height.
In this case,
Volume = 3 ft * 2 ft * 1 ft
= 6 ft^3
Because this tank is 2/3 full with water, to find out how much water is in the tank, we must multiply 2/3 by the total volume of the tank (6 ft^3).
2/3 * 6 ft^3 = 4 ft^3
This means that there are 4 cubic feet of water in the tank.
Hope this helps!
