Complete Question
Super Bowl XLVI was played between the New York Giants and the New England Patriots in Indianapolis. Due to a decade-long rivalry between the Patriots and the city’s own team, the Colts, most Indianapolis residents were rooting heartily for the Giants. Suppose that 90% of Indianapolis residents wanted the Giants to beat the Patriots. What is the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI?
Answer:
The value is [tex]P(X < 0.95) = 0.95224[/tex]
Step-by-step explanation:
From the question we are told that
The proportion that wants Giants to win p = 0.90
The sample size is n = 100
Generally the mean of this sampling distribution is
[tex]\mu_{x} = 0.90[/tex]
Generally the standard deviation is
[tex]\sigma = \sqrt{\frac{p(1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{ 0.90 (1- 0.90)}{100} }[/tex]
=> [tex]\sigma = 0.03[/tex]
Generally the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI is mathematically represented as
[tex]P(X < 0.95) = P(\frac{ X - \mu_{x}}{\sigma} < \frac{0.95 -0.90}{0.03} )[/tex]
[tex] \frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 0.95) = P(Z < 1.667 )[/tex]
=> [tex]P(X < 0.95) = 0.95224[/tex]

Jimmy is buying balloons and party hats for his little sister’s birthday party. The party store charges $1.50 for each bag of balloons and $6.00 for each package of hats. Which of the following equations could be used to determine different combinations of b bags of balloons and h packages of party hats that he could buy for a total of $24 ?
Answer:
4 bags of balloons and 3 bags of party hats
Step-by-step explanation:
1.50 x 4= 6
6 x 3= 18
6+18=24
The equation that could be used to determine different combinations will be 4b + 3h.
Based on the information given, the party store charges $1.50 for each bag of balloons and $6.00 for each package of hats.
Therefore, the equation that fits the explanation will be: 4b + 3h.
= 4b + 3h.
= 4(1.50) + 3(6)
= 6 + 18
= 24.
Therefore, the equation is 4b + 3h.

Find the measures of the labeled angles.
(x+92) =5xº
Answer:
X=23
Step-by-step explanation:
First you write the problem without the parenthesis so it's more easier to work out.
Second you need to do is change what is at the end of the problem all the way to beginning of the problem and also change the sign which should look something like this, x=5x-92.
Then you collect like terms which is ( 5x and x)
and sense x is 1 you subtract it and it would give you this -4x=-92. Divide both sides by 4 which would give you 23.

Set up an equation that models this statement.
Show, by solving the equation, that this equation will always be true for any three consecutive integers.
Answer:
By using Carl Gauss's clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.

Point A is rotated 90 degrees counterclockwise around point C to form the image A'. Select three true statements based on the given information.
Answer:
When we rotate a point A, around point C, the distance between the points is invariant.
This means that if A' es the image of the rotated point, then A' must lie in a circle centered in C with radius AC.
Then the correct statements are:
A' lies on a circle centered at point C with radius AC
This is by definition.
m∠ACA' = 90°
This is because A is rotated 90° around C to form the image A', then the measure must be 90°.
AC = A'C
As we already defined, the distance between the rotated point and the center of rotation is invariant, then the distance between A and C must be the same as the distance between A' and C.
Answer:
AC = A'C
A' lies on a circle centered at point C with radius AC
m∠ACA' = 90°
Step-by-step explanation:
When we rotate a point A, around point C, the distance between the points is invariant.
This means that if A' es the image of the rotated point, then A' must lie in a circle centered in C with radius AC.
As we already defined, the distance between the rotated point and the center of rotation is invariant, then the distance between A and C must be the same as the distance between A' and C.

Answer:
128calories/cup
256calories
Step-by-step explanation:
Given parameters:
Amount of calories = 96calories
Number of cups = [tex]\frac{3}{4}[/tex]cups
Unknown:
Unit rate(calories per cup) = ?
Number of calories in 2 cups = ?
Solution:
A. To find the unit rate;
Unit rate = [tex]\frac{amount of calories}{number of cups}[/tex]
Insert the parameters and solve;
Unit rate = [tex]\frac{96}{\frac{3}{4} }[/tex]
Unit rate = 96 x [tex]\frac{4}{3}[/tex] = 128calories/cup
B. Number of calories in 2 cups;
Amount of calories = unit rate x number of cups
Amount of calories = 128calories/cup x 2cups
Amount of calories = 256calories
