Answer:

Option C

Step-by-step explanation:

Add all grades together:

79 + 80 + 92 + 92 + 81 + 100 + 88 + 98 + 71 + 100 + 91 + 90 = 1062

Divide the total by the number of grades in the set:

1062/12 = 88.5

The average of the grades is 88.5%, therefore Option C should be the correct answer.

7/11 converted to a decimal rounded up 2 places
astraxan [27]

Answer:

0.636

Step-by-step explanation:

First off, we'll interpret the fraction bar to mean "divided by." This means that 7/11 is the same as 7 divided by 11.

Second, you have requested to see 2 decimal places in your answer, so we'll write the 7 as 7.00 instead (a 7 with 2 zeros after the decimal point).

Now, we'll just do what the fraction bar says: divide 7.00 by 11:

And that's about it! 7/11 written as a decimal to 3 decimal places is 0.636.

olga55 [171]

Answer:

y=10x-170

Step-by-step explanation:

This problem can be modeled by a linear function, where we have two points (37°C, 200) and (32°C, 150).

Notice that the temperature is the independent variable, because the heartbeat of the cat won't change the temperature, it works in the opposite way.

First, let's find the constant ratio of change.

m=\frac{150-200}{32-37}=\frac{-50}{-5}=10

This means the hearbeat of the car changes 10 pulses per minute each 1 celsius degree.

Now, we use the point slope formula to find the equation

y-y_{1} =m(x-x_{1} )\\y-150=10(x-32)\\y=10x-320+150\\y=10x-170

Theerefore, the function that represents this situation is

y=10x-170

Where x represents temperature and y represents hearbeats.
