Answer:
Submit Answer
attempt 2 out of 2
Answer:
8
Step-by-step explanation:
It appears your table includes points (4, 9) and (7, 33). The average rate of change on the interval is the slope of the line between these two points:
m = (y2 -y1)/(x2 -x1)
m = (33 -9)/(7 -4) = 24/3 = 8
The average rate of change is 8.

40% of athletes have tattoos and get into fights with other athletes. 50% of athletes get into fights with other athletes. What is the probability that an athlete that is getting into a fight has a tattoo
The probability that an athlete that is getting into a fight has a tattoo is 0.80
Let the events be represented as:
Event A : get into a fightEvent B: has a tattooSo, the probabilities are given as:
[tex]P(A\ n\ B) = 40\%[/tex]
[tex]P(A) = 50\%[/tex]
The probability that an athlete that is getting into a fight has a tattoo is represented as: P(B | A)
So, we have:
[tex]P(B | A) = \frac{P(A\ n\ B)}{P(A)}[/tex]
Substitute known values
[tex]P(B | A) = \frac{40\%}{50\%}[/tex]
Cancel out the percentages
[tex]P(B | A) = \frac{40}{50}[/tex]
Divide 40 by 50
[tex]P(B | A) = 0.80[/tex]
Hence, the probability that an athlete that is getting into a fight has a tattoo is 0.80

Find NMC triangle's perimeter if BO:BK=1:3 and ABC triangle's perimeter is 96
Answer:
80
Step-by-step explanation:
If we assume the triangles are similar and are isosceles, and that BK is an altitude, then we can work the problem.
Triangle OKN will be similar to triangle BKA, so ...
AN : AK = BO : BK = 1 : 3
Then ...
AN : AK : KC = 1 : 3 : 3
In terms of ratio units, ...
AN = 1
AC = 3+3 = 6
NC = 6-1 = 5
This means NC : AC = 5 : 6. The triangle perimeters will have the same ratio.
perimeter(NMC) = 5/6·perimeter(ABC) = 5/6·96
perimeter(NMC) = 80
Find the area of the region bounded by the graphs of the equations [tex]y=2x-x^2, y=0.[/tex] Provide a sketch. Show the work!
[tex]\\ \sf\longmapsto y=2x-x^2[/tex]
y=0[tex]\\ \sf\longmapsto 2x-x^2=0[/tex]
[tex]\\ \sf\longmapsto x^2-2x=0[/tex]
[tex]\\ \sf\longmapsto x(x-2)=0[/tex]
[tex]\\ \sf\longmapsto x=0,2[/tex]
⇒ y=2x−x2
y=0⇒ 2x - x² = 0
⇒ x² - 2x = 0
⇒ x ( x - 2 ) = 0
⇒ x = 0, 2

5. (5 points) Write the first 5 terms of the sequence if a1 = 9 and an-1 +n
Answer:
9,4,-1,-6,-11
Step-by-step explanation:
When n = 1: a(1+1) =a(1) +1
a(2) = -9 +1
a(2) = -8
When n = 2: a(2+1) =a(2) + 2
a(3) = -8 + 2
a(3) = -6
When n = 3: a(3+1) = -6 + 3
a(4) = -3

ABCD is a parallelogram. Determine the length of BE.
Answer:
BE = 102 units
Step-by-step explanation:
The diagonals of a parallelogram bisect each other , so
DE = EB , that is
- 8x + 14 = 3 - 9x (add 9x to both sides )
x + 14 = 3 ( subtract 14 from both sides )
x = - 11
Then
BE = 3 - 9x = 3 - 9(- 11) = 3 + 99 = 102 units

Convert 39/4 into a mixed number.
Answer: The answer is 9 3/4.
Step-by-step explanation: When converting an improper fraction to a mixed number, the first step to take is figure out how many times the denominator goes into the numerator. The number 4 goes into 39
9 times(4 x 9 = 36). The remainder 3 becomes the numerator of the denominator 4, therefore 39/4 converted to a mixed number is 9 3/4.
