Find the mean of the integers 5, -15, 7, -13, 1
A mean is an arithmetic average of a set of observations. The mean of the integers 5, -15, 7, -13, 1 is -3.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
The mean of the given integers can be written as,
Mean = Sum of observations/Number of observations
= [5 + (-15) + 7 + (-13) + 1]/5
= (5 - 15 + 7 - 13 + 1) / 5
= -15/5
= -3
Hence, the mean of the integers 5, -15, 7, -13, 1 is -3.

The rectangle below has an area of x^2-144 square meters and a length of x+12 meters. What expression represents the width of the rectangle?
The expression for the width of the rectangle is W = ( x - 12 )
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
We can use the formula for the area of a rectangle to find an expression for its width:
Area = length × width
The length of the rectangle is given as x + 12 meters, and the area is given as x² - 144 square meters.
We can substitute these values into the formula and solve for the width:
x² - 144 = (x + 12) × width
To solve for the width, we can divide both sides of the equation by x + 12:
width , W = (x² - 144) / (x + 12)
W = ( x + 12 ) ( x - 12 ) / ( x + 12 )
W = ( x - 12 )
Hence , the expression that represents the width of the rectangle is given by W = (x² - 144) / (x + 12) = ( x - 12 )

A recipe for banana bread requires 3 cups of bananas for every 1 1/2 cups of sugar used. At this rate, how many cups of sugar should be used if 2 cups of bananas are used
Answer:
4 cups of sugar will be added with 2 cups of banana in the banana recipe.
Step-by-step explanation:
A recipe for banana bread requires 3 cups of banana and [tex]1\frac{1}{2}[/tex] cups of sugar.
To calculate the cups of sugar used with 2 cups of bananas we will use unitary method.
∵ [tex]\frac{3}{2}[/tex] cups of sugar is used with amount of banana = 3 cups
∴ 1 cup of sugar will be used with banana = [tex]\frac{3}{\frac{3}{2}}[/tex]
∴ 2 cups of sugar will be used with banana = [tex]\frac{2\times 3}{\frac{3}{2} }[/tex] = [tex]6\times \frac{2}{3}[/tex]
= 4 cups
Therefore, 4 cups of sugar will be added with 2 cups of banana in the banana recipe.

Use the partial quotient strategy to solve 74 ➗ 3
To solve 74 ÷ 3 using the partial quotient strategy, you repeatedly subtract multiples of 3 from 74 until you reach a number less than 3. The final quotient is 24 with a remainder of 2.
Explanation:To solve 74 ÷ 3 using the partial quotient strategy, you repeatedly subtract multiples of 3 from 74 until you reach a number less than 3. Here are the steps:
Start with 74 and divide it by 3. The quotient is 0.Multiply 0 by 3 to get 0, and subtract it from 74 to get 74.Add 1 to the quotient, which becomes 1.Multiply 1 by 3 to get 3, and subtract it from 74 to get 71.Add 1 to the quotient, which becomes 2.Multiply 2 by 3 to get 6, and subtract it from 71 to get 65.Continue this process until you reach a number less than 3.

To find a baseball pitcher's earned run average (ERA), you can use the formula Ei = 9r, in which E represents ERA, i represents the number of innings pitched, and r represents the number of earned runs allowed. Solve the equation for E. What is a pitcher's ERA if he allows 25 earned runs in 54 innings pitched? If necessary, round your answer to the nearest hundredth. The equation for E is E = . If a pitcher allows 25 earned runs in 54 innings, then the ERA = .
Answer: ERA = 4.17
Step-by-step explanation:
1. First, you need to identify the data you get from the sentence.
Earned runs: 25 (r)
Innings pitched: 54 (i)
Earned runs average: ? (ERA/E)
2. Replace your data in the formula.
Ei = 9r
E(54) = 9(25)
3. Solve the operations.
E(54) = 225
4. Now we use the transposing method to find E (ERA). 54 is
multiplying E, so it's going to move to the other side of the
equation dividing like this.
E(54) = 225 ⇒ E = 225/54
5. Calculate the result for E.
E = 4.1666666667
6. Finally, we round our answer.
E = 4.17
So, the earned runs average (ERA) is 4.17.
