To find the mean, add up at the numbers and divide by the number of numbers in the set (6)
9 + 4 + 7 + 3 + 10 + 9 =
9 + 11 + 12 + 10
20 + 22
42
42 / 6 = 7
the mean is 7.
Answer:
Well your using absolute value and everything in absolute value is positive so you get rid of the negative.
Step-by-step explanation:
So you distribute the negative into the absolute value equation . And it leaves you with
|-1+5a|=29 now you can solve
your subtract your -1 from both sides bc you are solving for a
that gives you
5a=30 then you divide 5 divided by 30 is what 6 so that’s your answer
a=6
Answer:
THE THIRD ONE
Step-by-step explanation:
That diagram can be split into a right angled triangle of base 7 and of height 4 + 5.2 + 2 = 11.2, and a square of length of 5.2 So the are of the total shape is the area of the right angled triangle + the area of the square.
=

Answer:
C.
Step-by-step explanation:
We are given that
In I year, number of participants=88
In V year, number of participants=115
We have to find the equation of the trend line that can be generated by using the data from years 1 and 5.
Rate of change of participants =
Rate of change of participants,m=6.75
Point-slope form:
Where m=Rate of change of participants per year

By using the formula
Substitute the values then we get




Hence, option C is true.
