In the 2009 NFL regular season, quarterback Philip Rivers of the San Diego Chargers had an average of 266 passing yards per game with a standard deviation of 79 yards. Between which two values do you expect the middle 68% of his performance to be?
Your answer
A. 108 and 424
B. 29 and 503
C. 187 and 345
D. 0 and 582
Answer:
C. 187 and 345
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 266 yards per game, standard deviation of 79 yards.
Between which two values do you expect the middle 68% of his performance to be?
By the Empirical Rule, within 1 standard deviation of the mean. So between 266 - 79 = 187 yards and 266 + 79 = 345 yards. The correct answer is given by option C.
Suppose that P dollars in principal is invested in an account earning 2.1% interest compounded continuously. At the end of 2 yr, the amount in the account has earned $193.03 in interest.
A) Find the original principal.
B) Using the the original principal from part (a) and the model A = Pe", determine the time required for the investment to reach $6000.
Answer:
See explanation
Step-by-step explanation:
Recall that
Amount = Principal + Interest
The formula is;
A = P(1 + r)^n
Where;
P= principal, n = time and r = rate
Hence;
P + I = P(1 + r)^n
P + 193.03 = P(1.021)^2
P + 193.03 = 1.04P
P - 1.04P = - 193.03
-0.04 P = - 193.03
P = 193.03/0.04
P = $ 4825.75
B) When A = $6000, n=?
From;
A= P(1 + r)^n
6000 = 4825.75 (1.021)^n
6000/4825.75 = (1.021)^n
1.24 = (1.021)^n
Taking logarithm of both sides;
log 1.24 = n log 1.021
n = log 1.24/log 1.021
n = 0.0934/0.009
n = 10 years

Let O be a quadrant I angle with cos(0) ✓11/7 Find sin(20).
Answer:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(\theta)=\frac{\sqrt{11}}{7}[/tex]
Where θ is in QI.
And we want to determine sin(2θ).
First, note that since θ is in QI, all trig ratios will be positive.
Next, recall that cosine is the ratio of the adjacent side to the hypotenuse. Therefore, the adjacent side a = √(11) and the hypotenuse c = 7.
Then by the Pythagorean Theorem, the opposite side to θ is:
[tex]b=\sqrt{(7)^2-(\sqrt{11})^2}=\sqrt{49-11}=\sqrt{38}[/tex]
So, with respect to θ, the adjacent side is √(11), the opposite side is √(38), and the hypotenuse is 7.
We can rewrite as expression as:
[tex]\sin(2\theta)=2\sin(\theta)\cos(\theta)[/tex]
Using the above information, substitute. Remember that all ratios will be positive:
[tex]\displaystyle =2\Big(\frac{\sqrt{38}}{7}\Big)\Big(\frac{\sqrt{11}}{7}\Big)[/tex]
Simplify. Therefore:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]

Aaron is designing a party game in which he needs exactly 24 possible outcomes. Which sets of actions can he use to have a statistically fair
game?
Answer:
Counting from the top:
fist option
fourth option
fifth option.
Step-by-step explanation:
Any set that has a multiplicative outcome, such that the total number of outcomes is 24.
Remember that if we have a combination of two events, one with N outcomes and the other with M outcomes, the total number of outcomes is:
M*N
This is the main thing we need to see.
Let's analyze each option:
1) flip a coin (2 outcomes)
flip a coin again (2 outcomes)
roll a 6 sided dice ( 6 outcomes)
total number of outcomes:
2*2*6 = 24
2) Selecting a number from 1 to 16 (16 outcomes) and rolling a dice of 8 sides (8 outcomes).
The total number of outcomes is:
8*16 = 128
We wanted only 24.
3) Selecting a number from the set {1, 3, 5, 7, 9} (5 outcomes)
flip a coin (2 outcomes)
flip the coin again (2 outcomes)
total number of outcomes:
2*2*5 = 20
We wanted 24, we can discard this.
4) Spin the thing (3 outcomes)
roll an 8-sided dice (8 outcomes)
Total number of outcomes:
8*3 = 24
This is a correct option.
5) Select a card from A to D (4 outcomes)
Roll the thing (6 outcomes)
total number of outcomes:
6*4 = 24
This is a correct option.
6) Select a card from A to N {14 options}
Roll the thing once (10 outcomes)
Total number of outcomes:
14*10 = 140
We wanted 24, so we can discard this option.
Then the correct options are:
first one, fourth one, and fifth one.

How are translations and reflections represented as a function?
will give brainly and everything
Answer:
Step-by-step explanation:
A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f (−x) and results in the curve being "reflected" across the y-axis. You can see that the reflections are presented in the terms of a function.
As for translations, the function would just increase or decrease based on the translations.
In translation the graph of function moves certain distance and in reflection the graph of function reflected along the axis of reflection.
What is translation?"It is a transformation in which the graph of function is moved from one location to another location without changing its size, shape or orientation."
What is reflection?"It is a transformation in which the graph of function is reflected along the line of reflection."
What is function?"It defines a relation between input and output values"
Consider a function f(x).
Translations in function f(x):
1) When function f(x) is transformed to f(x) + k, it means function f(x) is translated vertically up by 'k' units.
2) When function f(x) is transformed to f(x) - k, it means function f(x) is translated vertically down by 'k' units.
3) When function f(x) is transformed to f(x + k), it means function f(x) is translated horizontally left by 'k' units.
4) When function f(x) is transformed to f(x - k), it means function f(x) is translated horizontally right by 'k' units.
Now consider reflections in function f(x):
1) When function f(x) is transformed to -f(x) , it means function f(x) is reflected over X-axis.
2) When function f(x) is transformed to f(-x) , it means function f(x) is reflected over Y-axis.
Therefore, in translation the graph of function moves certain distance and in reflection the graph of function reflected along the axis of reflection.

a rectangle has a height of 5 inches and a area of 35 squared inches what is the length of the base of the rectangle?
Please explain, I dont understand
Answer:
7 inches
Step-by-step explanation:
Now the area of a rectangle equals to length by width or in this scenario, height by base.
Therefore, we take a look at what we already have.
We got 5 inches for height and 35 squared inches as the area.
h= 5 inches a=35squared inches b=?
*Therefore, 5 x b =35
Through substitution this becomes:
*35/5= b
*Therefore b=7 inches

The U Gym provides weight resistance through adjustments of incline. The minimum weight resistance is 8% of the weight of the person using the U Gym. Find the minimum weight resistance possible for a 240-pound man.
The minimum weight resistance possible for a 240-pound man is
pounds.
(Type a whole number or a decimal.)
Answer:
The minimum weight resistance possible for a 240-pound man is 19.2 pounds.
Step-by-step explanation:
Since the U Gym provides weight resistance through adjustments of incline, and the minimum weight resistance is 8% of the weight of the person using the U Gym, to find the minimum weight resistance possible for a 240-pound man the following calculation:
240 x 8/100 = X
1,920 / 100 = X
19.2 = X
Thus, the minimum weight resistance possible for a 240-pound man is 19.2 pounds.

A hotel restaurant has a 75% customer approval rating for its service. The restaurant has a 60% customer approval rating for its service and its food. What is the probability that a restaurant customer approves of the food if he or she approves of the service?
The probability that a restaurant customer approves of the food given that they already approved of the service is 0.8, or 80%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Let's use Bayes' theorem to solve this problem.
= P(approves of food | approves of service)
By Bayes' theorem, we can express this probability in terms of the probabilities of approving of the service and the food separately:
P(approves of food | approves of service) = P(approves of service and food) / P(approves of service)
We know that the overall customer approval rating for the service is 75%, so:
P(approves of service) = 0.75
We also know that the customer approval rating for both the service and the food is 60%, so:
P(approves of service and food) = 0.60
Substituting these values into the formula, we get:
P(approves of food | approves of service) = 0.60 / 0.75
P(approves of food | approves of service) = 0.8
Therefore, the probability that a restaurant customer approves of the food given that they already approved of the service is 0.8, or 80%.

Answer:
48m²
Explanation:
since 3cm represents 4m, the width of the dining hall would be 4m. its length on the drawing is 9cm, which is 3 times of 3cm, so we can also multiply 4m by 3 to find the real length of the dining hall. this would give us 12m.
3cm : 4m
(multiply both by 3)
9cm : 12m
now, we can calculate the area of the dining hall using the equation 12m × 4m = 48m².
i hope this helps! :D
