Harold collected data on the daily high temperature in two cities over a period of one week.
Misha Larkins [42]

Answer:

Correct choices are 1 and 4

Step-by-step explanation:

As per data given we have:

  • Median temperature is 75°F and 88°F
  • And the range from the median is 5° for both cities

This gives us lowest temperatures of:

  • 75° -5° = 70° and 88° - 5°= 83° respectively

And high temperatures are:

  • 75° + 5° = 80° and 88° + 5° = 93°

<u>Answer choices based on above details:</u>

  • Choice 1 - correct
  • Choice 2 - incorrect. Correct answer is 93°
  • Choice 3 - incorrect. Correct answer is 93° - 70° = 23°
  • Choice 4 - correct

Round 8,764 to the nearest hundred
Zigmanuir [339]

Answer: 8,800

Step-by-step explanation:

Since the hundredth place is 764 we will round up to 800

which will give you 8,800!

Tip: Rounding the number up only takes place if the last two digits in the number are 50 or above.

If not, Round down if the last two digits in the number are 49 or below.

IF the last digits are 00 no rounding takes place.

The variables A, B, and C represent polynomials where A=x^2, B=3x+2, and C=x-3. What is AB-C^2 in simplest form?
yuradex [85]

Answer:

AB-C^2 = 3x^3 + x^2 + 9

Step-by-step explanation:

Hi

AB = (x^2)*(3x+2)= 3x^3 + 2x^2

C^2= (x-3)^2 = x^2 - 9

So

AB-C^2 = 3x^3 + 2x^2 - x^2 + 9 = 3x^3 + x^2 + 9
