The mean is equal for Group A and Group B.
<h2>Given </h2>
Two groups of students were asked how far they lived from their school.
The table shows the distances in miles:
Group A (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2
Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8
<h3>What is mean?</h3>
The mean of any data set or observation is equal to the sum of all the observations and divided by the number of observations.
The formula used to calculate the mean is;
The mean of group A is;
The mean of group B is;
Hence, the mean is equal for Group A and Group B.

Answer:
b = -24
Step-by-step explanation:
25+(11/12)b=3
Subtract 25 from each side
25-25+(11/12)b=3-25
11/12 b = -22
Multiply each side by 12/11 to isolate b
12/11* 11/12 b = -22*12/11
b = -2*12
b = -24
Answer:
D. $0, $20, $90
Step-by-step explanation:
If X represents the amount you win, then possible outcomes for X are $0, $20, and $90.
Answer:
P = 
Step-by-step explanation:
Q = 3P + 2 ( subtract 2 from both sides )
Q - 2 = 3P ( isolate P by dividing both sides by 3 )
= P
Answer:
£10
Step-by-step explanation:
There may be a far easier way to do this, but this is how I did it and still came up with the correct solution.
-Assuming they buy at least 15 bags, they will get a 20% discount.
-20% discount would mean they only pay 80% of the original price. 80%=.80
-let x represent number of bean bags
£50 per bean bag multiplied by sale price .80, plus cost of coffee machine £370 must be equal to or less than £1300.
(50x)(.80) + 370 = 1300
Simplify:
40x + 370 =1300
Subtract 370 from both sides
40x = 930
Divide both sides by 40
X=93/4
Simplify fraction
23 1/4
=23.25
But since they cant buy .25 (quarter) of a bean bag, we reduce* to nearest whole number. We can not increase* to nearest whole number as this would exceed their budget.
23 bean bags. They can buy 23 bean bags at £40 each + coffee machine for £370.
£40(23) + £370 = £1290
£1300-£1290=£10
I hope this helps!
