Answer:
a. (4, 26)
b. The number of people jogging in 2004 was 26 million.
c. 43 million
Step-by-step explanation:
To complete the ordered pair, use the given first value of the pair as the value of the variable in the equation. Evaluate the equation to find the second value of the ordered pair:
<h3>a.</h3>
y = x +22
y = 4 +22 = 26
The ordered pair is (4, 26).
__
<h3>b.</h3>
The ordered pair tells you (years after 2000, number of joggers in millions). That means the ordered pair (4, 26) tells you <em>4 years after 2000, there were 26 million joggers</em>.
__
<h3>c.</h3>
21 years after 2000, the value of x is 21, so the value of y is ...
y = 21 +22 = 43
There will be 43 million joggers in 2021.
Melissa and her younger sister are 5 meters apart.
<u>Step-by-step explanation</u>:
They form a right triangle,
- Height = her older brother 12 meters directly ahead of her .
- Base = her younger sister directly to her right.
- Hypotenuse = Melissa's brother and sister are 13 meters apart.
From the Pythagorean Triplets (5,12,13) :
The shortest side is the base of the right triangle.
Therefore, Base = 5 meters.
Melissa and her younger sister are 5 meters apart.
<h3>Answer:</h3>
d) 2.4
<h3>Explanation:</h3>
The mean is ...
... (12 +14 +10 +8 +16)/5 = 60/5 = 12
The deviations from 12 are ...
... {0, 2, -2, -4, 4}
The mean of the absolute values of these is ...
... (0 +2 +2 +4 +4)/5 = 12/5 = 2.4 . . . MAD
