Answer: I think it would be 40000/160/500
Answer:
x=10 and W=12
Step-by-step explanation:
Let's solve the equations. First we need to understand that the problem can be solved because we have two variables (x, W) and two equations.
Now, we have the following equations:
3x+3W-66 making the equation equal to 0:
3x+3W-66=0 which can be express as:
3x=-3W+66
x=(-3W+66)/3
x=-W+22 (equation 1)
The next equation is:
12x+15W-300 making the equation equal to 0 and then divided by 3:
(12x+15W-300)/3=0 which is:
4x+5W-100=0 (equation 2), using equation 1 we can write:
4(-W+22)+5W-100=0
-4W+88+5W-100=0
W-12=0
W=12
Using W=12 in equation 2 we have:
4x+5W-100=0
4x+5*(12)-100=0
4x+(60)-100=0
4x-40=0
4x=40
x=40/4
x=10
In conclusion the solution for the equations are: x=10 and W=12.

Answer:
The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.
Step-by-step explanation:
The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.
For a normal curve, the mean, median and mode are the same and represents the center of the distribution.
The center of the normal curve below is at the height 63 inches.
Thus, the mean of the distribution of heights of students at a local school is 63 inches.
The standard deviation represents the spread or dispersion of the data.
From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.
So, the standard deviation is 4 inches.
Step-by-step explanation:
Given,
No. of yards required for each quit = 3 7/8
can also be written as = 59/8
so,
yards,
required for 2 quilts = 2 × 59/8 = 14 3/4
required for 3 quilts = 3 × 59/8 = 23 4/8
required for 4 quilts = 4 × 59/8 = 8 1/2
