Given:
40 people
box plot data:
minimum age : 20
Q1: 28
Median: 34
Q3: 42
maximum age: 48
Q1 represents 25% of the data set.
40 x 25% = 10
There are 10 people who are aged 28 and below.
1st quartile is equal to 25% of the data set, the median is equal to 50% of the data set, 3rd quartile is equal to 75% of the data set.
Given
We have to set the restraint
because a square root is non-negative, and thus it can't equal a negative number. With this in mind, we can square both sides:
The solutions to this equation are 7 and -2. Recalling that we can only accept solutions greater than or equal to -1, 7 is a feasible solution, while -2 is extraneous.
Similarly, we have
So, we have to impose
Squaring both sides, we have
The solutions to this equation are 5 and 10. Since we only accept solutions greater than or equal to 7, 10 is a feasible solution, while 5 is extraneous.
Answer:
Same
Step-by-step explanation:
x=2 y=2
x=3 y=3
x=4 y=4
x=5 y=5
and then graph it
Answer:
y=-3.5x+9
Step-by-step explanation:
the slope is determined by the y1-y2/x2-x1 which is equaled to -5-2/4-2 which is equaled to -7/2 which is -3 1/2 which is your m value in y=mx+b and you graph to get your b value (y-intercept) which is 9
Answer: 2
Step-by-step explanation:
Vertical asymptotes can be solved by setting the denominator equal to zero.
x(x+1) = 0
Solve for 0 now by setting both x and x+1 equal to zero
x = 0
x + 1 = 0
x = -1
Because there are two factors in the denominator, the answer would be two.
The graph of that function has 2 vertical asymptotes (one at x=0 and the other at x=-1)
