Answer:

The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.

Solution:

Number of hours after 5 a.m.: x

At 10 a.m.→x=10-5→x=5

​ yˆ=−0.37(5)^2+6.15(5)+52.3

yˆ=−0.37(25)+30.75+52.3

yˆ=−9.25+30.75+52.3

yˆ=73.8

Answer: The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.

10/3+7)<br><br><br> i need help anyone got the answer ?
brilliants [131]

Answer:

Step-by-step explanation:

\frac{10}{3}+7 or \frac{10}{3+7}

If it is the former then first we will divide 10 by 3.

You get 3.333333

From there you will add 7 to that. You get 10.333333

If it is the latter then the answer is 1.

I know this because, you will first want to add 3 and 7. You get, 10.

Then you divide 10 by 10. Now you get 1.

Thus, the answer is 1.
