The final margin of an NFL football game is approximately normally distributed, with a mean equal to the gambling point spread and a standard deviation of 14 points. Recall the great 2008 Super Bowl in which the Giants upset the Patriots. The Patriots had been favored by 12 points. What does that fact imply about the Giants' initial (i.e., pre-game) chances of winning
Answer:
The Giants had 0.1949 = 19.49% probability of winning initially.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean equal to the gambling point spread and a standard deviation of 14 points. The Patriots had been favored by 12 points.
This means that [tex]\mu = 12, \sigma = 14[/tex]
What does that fact imply about the Giants' initial (i.e., pre-game) chances of winning
P(X > 0): Probability of Patriots winning.
P(X < 0): Probability of Giants winning.
So we want to find P(X < 0), which is the pvalue of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - 12}{14}[/tex]
[tex]Z = -0.86[/tex]
[tex]Z = -0.86[/tex] has a pvalue of 0.1949
The Giants had 0.1949 = 19.49% probability of winning initially.
Oatmeal is made by mixing 15 cups of hot water to 6 cups of oats.
9514 1404 393
Answer:
2/5 cups oats per cup water2.5 cups water per cup oatsStep-by-step explanation:
The denominator of the fraction is the unit you want 1 of.
(6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)
= (2/5 cups oats)/(1 cup water)
1 cup of water would need 2/5 cups of oats.
__
Obviously, the other ratio is the reciprocal of this.
(1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)
1 cup of oats would need 2.5 cups of water

In the year 2005, there were 100 rabbits in a particular region. Since then, the population has increased by 3.4% per year. Write an expression that represents the rabbit population in the year 2025, and solve it.
Answer:
Step-by-step explanation:
Your answer
Ok, lets do it systematically.
2005– 100 rabbits
3.4 % per year increasement.
So every year it increase 0.034 *100 = 3.4 per year
Total 2025-2005= 20 years
So expression is : 0.034*100*year(20)
Answer is : 3.4*20 = 68. So, in 2025, total rabbits will be 168

Answer:
A) -4
Step-by-step explanation:
There are two ways of solving this:
1.) Plugging in the answer choices
Since the equation needs to be equal to or less than 1 (this is due to the less than or equal to sign: ≤)
You will then set the equation: -2x-6 ≤ 1
You will then take each answer choice and plug it into the original equation.
Plug in -4: -2(-4)-6 ≤ 1 this will result in 2 ≤ 1
Plug in -3: -2(-3)-6 ≤ 1 this will result in 0 ≤ 1
Plug in -2: -2(-2)-6 ≤ 1 this will result in -2 ≤ 1
Plug in -1: -2(-1)-6 ≤ 1 this will result in -4≤ 1
The only one that is not true is when you plug in x=-4 into the equation -2x-6. This results in the equation being equal to 2. 2 is not less than 1, making the equation false.
Method 2: Solving the inequality
You can essentially solve for x like a normal inequality.
Instead of solving for -2x-6 = 1, we are doing -2x-6 ≤ 1.
First: Add 6 to the right side
-2x ≤ 1+6 --->>>> 2x ≤ 7
Second: Divid both sides by -2
***Note: When you divivde by a negative when solving an inequality, you must switch the sign. ***
x ≥ -3.5 (hence the sign swtiches from ≤ to ≥ since we divided by a negative value in the equation)
x ≥ -3.5 states that any number greater or equal to -3.5 will work. -4 is less than -3.5, thus it will not satisfy the inequality.
use long division to rewrite the expression in an equivalent form as q(x) + r(x)/b(x) , where q(x) is the quotient, r(x) is the x^3 - 2x^2 - 4/ (x-3)
Answer:
that looks hard good luck
Answer:
x^2 + x + 3 + 5/(x - 3)
Step-by-step explanation:
x - 3) x^3 - 2x^2 + 0x - 4( x^2 + x + 3
x^3 - 3x^2
x^2 + 0x
x^2 - 3x
3x - 4
3x - 9
5
So the answer is x^2 + x + 3 + 5/(x - 3)
7/8 Of the distance between two cities is 147 miles. How far apart are the two cities?
Answer:
168
Step-by-step explanation:
First, find the unit rate (the amount it increases with every 1/8)
147 ÷ 7 = 21
Next, multiply that by the denominator (8)
21 x 8 = 168
The answer is 168
Answer:
1/168

Data was collected on the amount of food (in grams) served at two restaurants and the price paid for the meal. The regression line for the data appears on the first plot. The second plot shows the regression analysis conducted when the data is analyzed separately for each of the two restaurants. Which of the following statements best describes the relationship between the variables?
a. The correlation between amount of food served and price is very strong within each restaurant, but seems weak when both restaurants are combined.
b. The correlation between amount of food served and price is strong.
c. The correlation between amount of food served and price is weak within each restaurant, but seems strong when both restaurants are combined.
d. The correlation between amount of food served and price is weak.
Answer:
Option A, The correlation between amount of food served and price is very strong within each restaurant, but seems weak when both restaurants are combined.
Step-by-step explanation:
The graphs for this question are provided in the attachment
Solution -
Graph I - the data points in the graph I do not follow any best fit curve or trendline. This indicates that data is not correlated.
Graph -II In graph II, apart from few outliners majority of data points lie on the best fist curve or the trendline.
Hence, the relation between the two variables i.e food served and price is strong.
Option A fits well for our answer hence it is the correct answer
A movie theater charges $12.00 for adults and $4.50 for children under the age of ten. A group of adults and children went to the movies and spent $75.00 on 10 tickets. How many adults and how many children went to the move?
Answer:
4 Adults and 6 Children went to the movies.
Step-by-step explanation:
(Children) $4.50 x 6 = $27.00
(Adults) $12.00 x 4 = $48.00
$48.00 + $27.00 = $75.00

A statue of George Washington is also in Druids a 15 m away from the statue and places a mirror 12 m from the statue (3 m from her feet)she can see the top of the statue in the mirror. The girl's height is How tall is the statue(draw a diagram and solve)
Answer:

Let 'x' represent the height of the statue.
1 ft = 0.3048 m
5.5 ft = 5.5*0.3048 m
Using the similar triangles we can write:
x : 3 = 12 : (5.5*0.3048)
x = 21.47 m
The statue is 21.47 meters tall

How are rational exponents and radicals related? Summarize how to rewrite a rational power as a radical term using an example of your own.
Answer:
Hi
Step-by-step explanation:
Rational exponent are exponents written in the form of a fraction.
A rational power can be rewritten as a radical in the following way: the bottom of the rational exponent is the root, while the top of the rational exponent is the new exponent on the radical.
Example: X^(1/2)= √X
If this figure is dilated by a scale factor of 3, what would the new coordinates be?
Answer:
J (-3,3), G (0,3), H (4,9), I (3,3)
Step-by-step explanation:
When your dilating a figuring it either gets larger or smaller. Since this is a positive number, and it is not a fraction then the figure is getting larger. Now you multiply each of the original coordinates by 3 to get the dilated coordinates.
