Marcus reads in a magazine article that 62% of teenagers prefer Batman over Iron Man. He decides to test this so he takes a simple random sample of 50 people at Wal-Mart on a Sunday afternoon. What is the probability that he finds exactly 40 Batman fans? Round to the nearest thousandth.
Answer:
The probability is 0.003
Step-by-step explanation:
If 62% prefers Batman, the percentage that prefers Iron man will be (100-62)% = 38%
So the probability of finding a teenager that likes batman will be 62/100 = 0.62
The probability of finding a teenager that prefers iron man will be 38/100 = 0.38
Now, we want to find the probability that out of 50 people at Walmart on a Sunday, exactly 40 prefers Batman
We can use the Bernoulli approximation of the binomial theorem ;
let probability of liking Batman be q and that of iron man be q
Thus the approximation will be;
P(X = 40) = 50 C 40 (0.62)^40 (0.38)^10
= 0.003200147531
To the nearest thousandth, this is 0.003

Max and his brother exercise together. Max does half as many sit-ups as his brother does during a workout. If Max's brother does between 100 and 150 sit-ups, which expression describes s, the number of sit-ups that Max does?
A. 0 ≤ s ≤ 50
B. 50 ≤ s≤ 75
C. 100 ≤ s ≤ 150
D. 200 ≤ s ≤ 300
Answer:C is the correct answer,
Step-by-step explanation:
50 ≤ s≤ 75 describes the number of sit-ups that Max does so option (B) will be correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Max does "s" number of sit-ups then max brother will do "2s".
Now,
Given that,
Max's brother does between 100 and 150 sit-ups
So,
100 ≤ 2s ≤ 150
Divide by 2 into both sides
50 ≤ s ≤ 75
Hence " 50 ≤ s≤ 75 describes the number of sit-ups that Max does".

On another training ride, Jana bikes 15 miles in 50 minutes. Explain how you
could find the number of miles she bikes in 1 hour
Answer:
18 miles per hour
Step-by-step explanation:
If you divide 15 (miles) into 50 groups (min) you will get Jana's speed per min and then you can multiply that speed by sixty to her the speed per hour.
The graph shows the linear parent function . Which statement best describes the function?
A. The function is negative when x<0 and also when x>0
B.the function is never negative
C.the function is negative when x>0
D. The function is negative when x<0
Using function concepts, it is found that the correct option is given by:
D. The function is negative when x<0
How the sign of a function is determined?If the graph is above the x-axis, it is positive.If the graph is below the x-axis, it is negative.In this problem, the graph of the function is the red line, and:
For values of x < 0, the function is below the x-axis, hence it is negative.For values of x > 0, the function is above the x-axis, hence it is positive.Thus, option D is correct.

Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?
Step-by-step explanation:
A. For Tavon's gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=145-3.5x------1
for Tavon's second gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=125-3x-------------2
B. equating 1 and 2 we have
145-3.5x=125-3x
solve for x we have
145-125=-3x+3.5x
20=0.5x
divide both sides by x we have
x=20/0.5
x= 40
put x=40 in
y=145-3.5*40------1
y=145-140
y=$5
put x=40 in
y=125-3*40------1
y=125-120
y=$5

Answer:
Made $840 in commissions for the past month.
Step-by-step explanation:
sales = 70 * 150 = 10500
commission = .08 * 10500 = 840
Answer:

What is the value of x? What is the measure of angle 6? Show all of your work and/or explain your answer.
Answer:
1) 5 & 9
5=Corresponding Angle
9=Alternate Exterior Angle
2) 7 & 8
We know 4 is supplementary to 8. Since that is true, 7 & 8 are also.
8=Corresponing angle to 4
7=Verticle angle to 8
3) We know 1 and 3 equal 180
x-20+x+40=180
2x+20=180
2x=180-20
2x=160
x=80
<2=X+20
=80+20
=100
Angle 2 is the same as angles 5 and 6 added together.
We know angle 5 is the same as angle 1 (corresponding angles).
<1=X-20
=80-20
=60
Now that we know <2=100 and <5=60, we can figure out <6
100-60=40
<6=40°
Step-by-step explanation:
1) 5 & 9
5=Corresponding Angle
9=Alternate Exterior Angle
2) 7 & 8
We know 4 is supplementary to 8. Since that is true, 7 & 8 are also.
8=Corresponing angle to 4
7=Verticle angle to 8
3) We know 1 and 3 equal 180
x-20+x+40=180
2x+20=180
2x=180-20
2x=160
x=80
<2=X+20
=80+20
=100
Angle 2 is the same as angles 5 and 6 added together.
We know angle 5 is the same as angle 1 (corresponding angles).
<1=X-20
=80-20
=60
Now that we know <2=100 and <5=60, we can figure out <6
100-60=40

4) After solving a rational equation you must check your solutions in the
original equation. Why? *
To make sure the value does not make the numerator 0.
O
To make sure the value does not make the denominator 1.
O To make sure the value does not make the numerator negative.
To make sure the value does not make the denominator 0.
Answer: D) To make sure the value does not make the denominator 0.
We cannot divide by zero. Something like 1/0 is undefined. So it's important to check all potential solutions to make sure you don't get 0 in the denominator.
