Answer:
-2
Step-by-step explanation:
g(2) = 5*2-7 = 3
f(g(2)) = f(3) = 3^2 - 3*3 - 2
= 9-9-2
= -2
Step-by-step explanation:
Given n = 4
2n = 2* 4= 8
n + 2 = 4 + 2 = 6
3(n + 4) = 3( 4 + 4) = 3 * 8 = 24

What is the third quartile of this data set 20,21,24,25,28,29,35,37,39,42,44
dezoksy [38]
Answer:
The third quartile would be <u>39</u>.
Step-by-step explanation:
• Since the numbers are already in order, the next step would be to find the median:
- The <u>median</u> is the middle number; found by ordering all data points and picking out the one in the middle.
• The <u>first quartile</u>, is denoted as Q1 and is the middle number that falls between the smallest value of the data set and the median.
- The first quartile would be 24.
• The <u>third quartile</u>, is denoted as Q3 and is the median of the upper half of the data set.
- The third quartile would be 39.

Answer:
the first one
Step-by-step explanation:
check which graph passes through the point (2,4)
let l = lance, and a = alex.
so: l + a = 70
and l = 4a
Putting the value for l in the first equation:
4a +a = 70
5a = 70
a = 14.
So Alex has 14 pencils. And Lance has (70-14) 56 pencils.
And if each child gets half of Alex' pencils, then each child will have 7 pencils.
