Which statement is true? P(age between 25 and 35 years|hemoglobin level between 9 and 11) P(age between 25 and 35 years)
P(hemoglobin level between 9 and 11|age between 25 and 35 years) = P (hemoglobin level between 9 and 11)
P(hemoglobin level between 9 and 11|age between 25 and 35 years) = P(age between 25 and 35 years)
P(age between 25 and 35 years|hemoglobin level between 9 and 11) = P(hemoglobin level between 9 and 11|age between 25 and 35 years)
P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..

1. Elena bought 320 tropical fish for a museum display. She bought 7 times as many triggerfish as parrotfish. How many of each type of fish did she buy?Which is a system of equations to model the problem if x represents the number of parrotfish Elena bought and y represents the number of triggerfish she bought?

A. x + 7y = 320
y = 7x

B. x + y = 7
y = 320x

C. x + y = 320
y = 7x

D. x−y=320
y = 7x

2. Nancy bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as angelfish.

3. Michael and Kathryn bowl together and their combined total score for one game was 425 points. Michael’s score was 70 less than twice Kathryn’s. What were their scores?

Which is a system of equations to model the problem if x represents Kathryn’s score and y represents Michael’s score?

A. x + y = 70
y = 2x – 425

B. x + y = 425
y = 2x – 70

C. x – y = 425
y = 2x – 70

D. x + y = 425
y = 2x + 70

How many nickels are there?

A. 12

B. 18

C. 49

D. 55

Answers

Answer:

Step-by-step explanation:

If im wrong, please correct me in the comments.

Answer:

5. D, Let d represent the number of dimes and n represent the number of nickel. We have been given that a collection of coins has 67 coins in all. This means that total number of nickels and dimes is 67. We can represent this information in an equation as:

Since we know that a dime is worth $0.10, so d dimes will be worth 0.10d.

A nickel is worth $0.05, so n nickels will be worth 0.05n. We are also told that the collection is worth $6.10. We can represent this information in an equation as:

We will use substitution method to solve system of linear equations. From equation (1) we will get, upon substituting in equation (2) we will get, Let us divide both sides of our equation by .
