Answer:

f(- 2) = 2

Step-by-step explanation:

To evaluate f(- 2), substitute x = - 2 into f(x)

f(- 2) = 3(- 2)² + 5(- 2) = (3 × 4) - 10 = 12 - 10 = 2

Answer:

2

Step-by-step explanation:

f(x) = 3x^2 + 5x

f(-2) = 3(-2)^2 + 5(-2)

f(-2) = 3(4) + 5(-2)

f(-2) = 12 + -10

f(-2) = 2

the average of the five number was 6.8. If the first four numbers were 4.3, 5.2, 7, and 6.8, What was the fifth number?
Nikolay [14]
Let x be the fifth number
\frac{4.3 + 5.2 + 7 + 6.8 + x}{5} = 6.8
⇔ \frac{23.3 + x}{5} = 6.8
⇔ 23.3 + x = 34
⇔ x = 10.7

Zoe is doing a survey to find the time her classmates spend playing video games. She asks the following question:
Vladimir [108]
The data she would collect would be grouping people depending on how much video games they played. 

This however, is not a statistical question. Instead, she should set for example: 1-3 hrs per week, 4-6 hrs, etc. People play different amounts of hours, and so you cannot set a specific number, it must be a "range-of-numbers".

Also the question itself is kinda judging and comparative

so overall, umm... this question isn't really good

hope this helps :D

We have to find how many burgers can be made:

We have to divide 3.5 pound by 0.25 pound

i.e,

⇒14 quarter pounds burger can be made.

Therefore, 14 quarter pound burgers can George make out of 3 1/2 pounds of ground beef
