The outlier  is 20

it affect the mean because

1)32 +40+34+ 31 +20+ 36 +40+31=264

2) 264 divided by 8= 33

so it gives you an odd number

The spinner at the right is divided into eight equal parts. Find the theoretical probability of
finlep [7]

Answer:

\frac{3}{4} probability of landing on a number greater than 2 on the spinner.

Step-by-step explanation:

A theoretical probability is given by the number of desired outcomes divided by the number of total outcomes.

In this question:

8 possible outcomes(all numbers from 1 to 8).

6 desired outcomes(3, 4, 5, 6, 7 and 8, that is, all the numbers greater than 2). So

p = \frac{6}{8} = \frac{3}{4}

\frac{3}{4} probability of landing on a number greater than 2 on the spinner.

Simplify the expression (2x − 9)(x + 6)
kenny6666 [7]

<u>Answer:  </u>

Simplified form of given expression (2x – 9 )( x + 6 )  is 2 \mathrm{x}^{2}+3 \mathrm{x}-54

<u> Solution: </u>

We need to simplify following expression.

(2x – 9) ( x + 6)  

For sake of simplicity lets first assume 2x – 9 = A

So expression becomes A(x+6)

= Ax + A6

Now replace A by 2x – 9

= (2x – 9 ) x + (2x – 9 ) 6

=2 \mathrm{x}^{2}-9 \mathrm{x}+12 \mathrm{x}-54

On simplification, we get

=2 \mathrm{x}^{2}+3 \mathrm{x}-54

Hence simplified form of given expression (2x – 9 )( x + 6 )  is = 2 \mathrm{x}^{2}+3 \mathrm{x}-54

Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week
Yuri [45]

Answer:


Step-by-step explanation:

This is what i get what i understand from your question .

Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week


So ,

$7 =per hr

X= unknown hrs

$35= goal


7 x =35


Divide both sides by 7 to get x alone representing hrs.


X= 35/7

X= 5


So 5 hrs per week to make 35 a week.


5×7=35

35=35
