Answer:
Number of hot dogs sold = 56
Number of hamburgers sold = 52
Step-by-step explanation:
Let
Number of hot dogs sold = x
Number of hamburgers sold = y
We can make equation from given equations:
(Hot dogs were sold for $.50 (fifty cents), and hamburgers were sold for $1 (one dollar). The total money raised by your class was $80. )
(Together you sold 108 hot dogs and hamburgers.)
Now we cam solve these system of equations to find value of x and y

Subtract both equations to get value of x:

We get value of x = 56
Now putting value of x in equation 2 to find value of y

So, we get y = 52
Therefore,
Number of hot dogs sold = x = 56
Number of hamburgers sold = y = 52

Answer:
7.3% percentage of the bearings produced will not be acceptable.
Step-by-step explanation:
Consider the provided information.
Average diameter of the bearings it produces is .500 inches. A bearing is acceptable if its diameter is within .004 inches of this target value.
Let X is the normal random variable which represents the diameter of bearing.
Thus, 0.500-0.004<X<0.500+0.004
0.496<X<0.504
The bearings have normally distributed diameters with mean value .499 inches and standard deviation .002 inches.
Use the Z score formula: 
Therefore



Now use the standard normal table and determine the probability of that a ball bearing will be acceptable.
We need to find the percentage of the bearings produced will not be acceptable.
So subtract it from 1 as shown.
1-0.9270=0.073
Hence, 7.3% percentage of the bearings produced will not be acceptable.
The perimeter of a triangular window is the sum of its side lengths
The side lengths of the window are 33 inches, and 54 inches
<h3>How to determine the side lengths?</h3>
The ratio is given as:
Ratio = 11: 18 : 18
Rewrite as:
Ratio = 11x: 18x : 18x
Express as sum
Sum = 11x + 18x + 18x
Sum = 47x
The perimeter is 141 inches.
So, we have:
47x = 141
Divide both sides by 47
x = 3
Recall that:
Ratio = 11x: 18x : 18x
So, we have:
Ratio = 11*3: 18*3 : 18* 3
Ratio = 33: 54 : 54
Hence, the side lengths of the window are 33 inches, and 54 inches
