The factors of m2 + 12m + 35

Answers

Answer:

(m + 7)(m + 5)

Step-by-step explanation:

Factor, find factors of m² & 35 that, when combined, will give 12m:

m² + 12m + 35

m                 7

m                 5

(m + 7)(m + 5) is your answer.

Check: Use the FOIL method to check.

(m)(m) = m²

(m)(5) = 5m

(7)(m) = 7m

(7)(5) = 35

Combine like terms:

m² + (5m + 7m) + 35 = m² + 12m + 35 √.

Answer:

(m+7) and (m+5)

At one gas station, gas costs $2.75 per gallon. Write an equation that relates the total cost, C , to the number of gallons of gas purchased, g.

Answers

Answer:

C = 2.75g

Step-by-step explanation:

The total cost of the gas purchased is the product of the price per gallon and the number of gallons.

Hope this helps. :)

Final answer:

The equation that relates the total cost (C) to the number of gallons of gas (g) is C = 2.75g. This equation indicates that to find the total cost, you multiply the number of gallons by $2.75.

Explanation:

The question is asking for an equation that relates the total cost (C) to the number of gallons of gas purchased (g). Since the cost of gas is $2.75 per gallon, you multiply the number of gallons by $2.75 to find the total cost. Therefore, the equation that represents this relationship is C = 2.75g.

This equation states that the total cost (C) is equal to the cost per gallon ($2.75) multiplied by the number of gallons of gas (g). For instance, if you buy 10 gallons of gas, you would plug in 10 for g in the equation like this: C = 2.75 * 10, which will give you $27.50.

13. Mr. Smith teaches history and math classes. He has 25 students in both classes combined. He has 17 students in the math class and 15 students in the history class. Is it possible that 12 stu- dents are enrolled in both his history and his math classes?!

Answers

Answer:

  no

Step-by-step explanation:

If m, h, b represent the numbers of students in Mr. Smith's math, history, and both classes, then we have ...

  m + b = 17

  h + b = 15

  m + b + h = 25

Adding the first two equations and subtracting the third gives ...

  (m+b) +(h+b) -(m+b+h) = (17) +(15) -(25)

  b = 7 . . . . . . simplify

The number enrolled in both of Mr. Smith's classes is 7, not 12.

_____

Here, m and h represent the number of students enrolled in only one of Mr. Smith's classes, math or history, respectively.

From the records of a health-insurance companies in Pennsylvania, it is known that 58% of the accounts include dental coverage. A researcher would like to take a random sample of 500 accounts to review. Find the standard deviation of the sample proportion in this situation. Give your answer to 4 decimal places. For help on how to input a numeric answer, please see "Instructions for inputting a numeric response."

Answers

Answer: 0.0221

Step-by-step explanation:

We know that the formula to find the standard deviation of the sample proportion is :

\sigma_p=\sqrt{(p(1-p))/(n)}

, where p = proportion of success.

n= sample size.

As per given , we have

p=0.58

n= 500

Then, the standard deviation of the sample proportion in this situation would be :

\sigma_p=\sqrt{(0.58(1-0.58))/(500)}\n\n=\sqrt{(0.2436)/(500)}\n\n=√(0.0004872)\n\n\approx0.0221

Hence, the standard deviation of the sample proportion in this situation is 0.0221 .
