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.

Leader is a stockbroker 14% commission each week last week she said $7200 worth of stocks how much did she make last week interm
Feliz [49]

Answer:

$1,008 weekly,  $52,416 annually

Step-by-step explanation:

14% of $7200 is 7200 multiplied by .14 (% is decimal multiplied by 100)

.14 of 7200 = 1008

Since you specified the year, I'm going to assume that you need the annual salary based on the weekly salary that she gets from commissions.

$1008 per week, 52 weeks in a year

52 * 1008 = $52416, her commission in 2011

PLEASE HELP<br> Solve. x^2+9x+2=0
Nataliya [291]

Answer:

x = (1/2) (-9 ± √73)

Step-by-step explanation:

Using completing the square method

x²+9x+2=0

x²+9x = -2   (complete the square by adding (9/2)² to both sides)

x²+9x + (9/2)² = -2 + (9/2)²

( x + (9/2) )² = -2+ (9/2)²

( x + (9/2) )² = -2+ (81/4)

( x + (9/2) )² = 73/4

x + (9/2)  = ± √(73/4)

x + (9/2)  = ± √(73) / 2

x = -(9/2) ± √(73) / 2  (factorize out (1/2) )

x = (1/2) (-9 ± √73)
