Distribute 5g to all of the terms in parentheses:

5g \times -3g^2h = -15g^3h
5g \times -7g = -35g^2
5g \times 9 = 45g

-15g^3h - 35g^2 + 45g

The answer is A.

Identify whether each question is a statistical question and the reason why or why not.
madam [21]

1. The question about the weight of the football team players is statistical because it requires data collection to answer it and the data is variable.

2. The question about the height of Ben's mother is <u>non-statistical</u> because it does not require data collection to answer and the data is not variable, since it is one data point.

<h3>What is a statistical question?</h3>

A statistical question can be answered by collecting data and for which data will vary.

Questions answered with a single data point are <u>not statistical</u> because there is no data variability to answer them.

A statistical question can be determined by the following criteria:

  • Provides useful data about a group of people.
  • Many people can answer it.
  • There will be many different answers.
  • The data collected explains a situation or reality.

Thus, the question about the weight of the players asks a statistical question, unlike the height of Ben's mother.

At a regional soccer​ tournament, tickets for two adults and seven students cost ​$60. Tickets for three adults and eleven stude
den301095 [7]

Answer:

The price of an adult ticket is $9 and the price of a student ticket is $6

Step-by-step explanation:

Create a system of equations where x is the price of an adult ticket and y is the price of a student ticket:

2x + 7y = 60

3x + 11y = 93

Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2, to cancel out the x terms:

6x + 21y = 180

-6x - 22y = -186

Add them together:

-y = -6

y = 6

Then, plug in 6 as y into one of the equations to solve for x:

2x + 7y = 60

2x + 7(6) = 60

2x + 42 = 60

2x = 18

x = 9

So, the price of an adult ticket is $9 and the price of a student ticket is $6
