Answer:

140  

Step-by-step explanation:

The table is:

<u>                |Sample 1      | Sample 2</u>

catfish     | 3                 | 5

bass         | 9                 | 9

trout         | 8                 | 6

all fish      | 20               | 20

The average number of trouts is (8 + 6)/2 = 7

The average number of the total amount of fish is 20

So, there are 7 trouts within 20 fish. To find the expected number of trouts in a population of 400 fish, we have to solve the next proportion:

7 trouts / 20 fish = x trouts / 400 fish

x = 7*400/20

x = 140 trouts

Consider the graph of the equation y = 5. Which statements are true? Check all that apply.
levacccp [35]

Answer:

The graph of y=5 is a horizontal line. The point (-4, 5) lies on the lines.

Step-by-step explanation:

This is horizontal because 5 on the y axis is always going to stay the same. For any x value, the y value is 5. Therefore, (-4, 5) is part of that line.

Tyson brought a bag of coins into the bank to be counted. The bag contained only nickels and
podryga [215]

There will be 130 nickels and 90 dimes. 100 nickels is 5 dollars. 90 dimes are 9 dollars. And then there will be 30 left. 30 dimes isn’t 1.50$ bur 30 nickels is 1.50$ so you add the 30 to the nickels and it’ll be exactly 15.50$.

2. It’s time for Ronda to start repaying her student loans, which are amortized over the next 10 years. Her first month’s paymen
grigory [225]

Based on the amount that she paid in the first month, the amount Ronda will pay for the next month is<u> $396.</u>

When a loan is amortized, it means that one can pay it off by paying the same amount every period until they would have paid off both the loan and the associated interest.

The amortized amount contains:

  • A portion going towards the principal(debt )
  • A portion going towards the interest accumulated.

In conclusion, as the amount is the same every time, Ronda will have to pay the same amount of $396 the next month.
