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
I am thinking of a positive integer that is 3 less than 3 times another number. The product of my number and the other number is 90.
a. Write an equation to represent this situation.
b. What is my number?
Answer:
your numnber is 15
Step-by-step explanation:
3x-3=n
nx=90
nx=90
(3x-3)x=90
3x^2-3x=90
x=6
3x-3=n
3(6)-3=n
18-3=n
15=n
6> z(10-z)
Which number is a solution of the inequality?
Answer:
6 > z(10 - z)
6 > 10z - z^2
z^2 - 10z^2 + 6 < 0
z > 9.36, z < 0.64
Therefore, option (0) is the correct answer.

What goes in each drop down menu?
Answer:
x = 95 y = 137 z = 128
Step-by-step explanation:
z = 180 - 52 = 128 z plus 52 have to be equal to 180
Angle coincident of x is equal to 180 - (45 + 50) = 85
x = 180 - 85 = 95
Angle coincident of y is equal to 180 - (85 + 52) = 43
y = 180 - 43 = 137

Answer:
a. y=30(20)+800
y=1400
b. 700
Step-by-step explanation:
Answer: Answers are in the steps, please read carefully.
Step-by-step explanation:
A. Since each of the twenty people paid $30 each and an $800 was raised, then the expression will be multiplying 20 by 30 and adding it to 800. To find the value of the expression, multiply 20 by 30 then add it to find the result.
Expression: 20(30) + 800
Value of Expression: 600 + 800 = 1400
B. If the money is being split equally among two organizations, then is the same as diving the money by 2 to find how much each organization received.

What are the solutions to the quadratic equation 3(x − 4)2 = 75?
x = −9 and x = 1
x = −5 and x = 5
x = −4 and x = 4
x = −1 and x = 9
Answer:
x=-1 and x=9
Step-by-step explanation:
[tex]3(x-4)^{2} =75[/tex]
[tex](x-4)^{2} =\frac{75}{3}[/tex]
[tex](x-4)^{2}[/tex]=[tex]25[/tex]
[tex](x-4)(x-4)[/tex]=[tex]25[/tex]
[tex]x^{2} -4x-4x+16[/tex]=[tex]25[/tex]
[tex]x^{2} -8x+16[/tex]=[tex]25[/tex]
[tex]x^{2} -8x+16-25=0[/tex]
[tex]x^{2} -8x-9=0[/tex]
[tex](x-9)(x+1)=0[/tex]
[tex]x-9=0\\x=0+9\\x=9[/tex] [tex]x+1=0\\x=0-1\\x=-1[/tex]
therefore x=9 and x=-1

Horizontal lines e and f are intersected by lines a and b. At the intersection of lines a and e, the uppercase left angle is 75 degrees. At the intersection of lines b and e, the uppercase right angle is 115 degrees. At the intersection of lines a and f, the bottom right angle is 75 degrees.
Which lines are parallel? Justify your answer.
Lines a and b are parallel because their alternate exterior angles are congruent.
Lines a and b are parallel because their same side exterior angles are supplementary.
Lines e and f are parallel because their alternate exterior angles are congruent.
Lines e and f are parallel because their same side exterior angles are congruent.
Lines e and f are parallel because their alternate exterior angle is congruent. Option C is correct.
Find the diagram attached;
The point where two lines meet is known as an angle.
From the given diagram, we can see that the angle of 75 degrees is at the top left corner is similar to the 75 degrees down right.Hence we can conclude that lines e and f are parallel because their alternate exterior angle is congruent.Learn more here: https://brainly.com/question/11397920

Write in exponential form 2/3 * 2/3*p*p please help
Answer: [tex]\left(\frac{2}{3}p\right)^2[/tex]
======================================
Explanation:
The expression [tex]\frac{2}{3}*\frac{2}{3}*p*p[/tex] is the same as [tex]\frac{2}{3}*p*\frac{2}{3}*p[/tex]
This is because we can multiply in any order.
If we let [tex]x = \frac{2}{3}*p[/tex], then [tex]\frac{2}{3}*p*\frac{2}{3}*p = x*x = x^2 = \left(\frac{2}{3}p\right)^2[/tex]
