Answer:
its righties b
Step-by-step explanation:
P varies inversely with the
square of Q. When Q is 8, P is 9.
Find the value of P when Q is 3.
The required value of P would be 64 for the given linear relationship.
What is the linear relationship?A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
Given that P varies inversely with the square of Q
P = k/Q²
As per the question, if Q is 8 and P is 9,
So 9 = k/8²
⇒ 9 = k/64
Apply cross-multiplication operation,
⇒ k = 576
If Q is 3, then
⇒ P = 576/3²
⇒ P = 576/9
Apply division operation, and we get
⇒ P = 64
Thus, the required value of P would be 64.

Your neighbor has a bag with 5 oranges and 7 apples in it. You will be receiving two pieces of fruit from your neighbor. What is the probability, in percent, that you will receive 2 apples, assuming she removes them from the bag in random order
Answer:
31.82% probability that you will receive 2 apples.
Step-by-step explanation:
The fruits are removed from the bag, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
5 + 7 = 12 total fruits, which means that [tex]N = 12[/tex]
7 apples, which means that [tex]k = 7[/tex]
You receive 2 fruits, which means that [tex]n = 2[/tex]
What is the probability, in percent, that you will receive 2 apples, assuming she removes them from the bag in random order?
This is, as a proportion, P(X = 2). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,12,2,7) = \frac{C_{7,2}*C_{5,0}}{C_{12,2}} = 0.3182[/tex]
0.3182*100% = 31.82%
31.82% probability that you will receive 2 apples.

Obtain an estimate for the following computation by rounding the numbers so that the resulting arithmetic can easily be performed by hand or in your head. Then, use a calculator to perform the computation. How reasonable is your estimate when compared to the actual answer? 359+558 Round the two numbers to the nearest ten. An estimate of the sum is:______. The actual sum is How reasonable is your estimate when compared to the actual answer? A. Not reasonable. The estimate seems too low compared to the actual answer B. Reasonable. The estimate seems a little tower compared to the actual answer. C Reasonable. The estimate sooms a little higher compared to the actual answer. D. Not reasonable. The estimate seems too high compared to the actual answer
Answer: C. Reasonable. The estimate sooms a little higher compared to the actual answer
Step-by-step explanation:
The actual answer to 359+558 is 917. On the other hand, 359 to the nearest ten is 360 while 558 to the nearest ten is 560. The addition of the numbers will be: = 360 + 560 = 920
The estimated answer is 920 while the actual number is 917. Therefore, the estimate is reasonable as the estimate sooms a little higher compared to the actual answer.

When Shaquana commutes to work, the amount of time it takes her to arrive is normally distributed with a mean of 22 minutes and a standard deviation of 3 minutes. Using the empirical rule, determine the interval that represents the middle 95% of her commute times.
Answer:
16,28
Step-by-step explanation:
The requried interval that represents the middle 95% of Shaquana's commute times is (16, 28) minutes
What is an empirical rule?The empirical rule, also known as the three-sigma rule, is a statistical concept that provides a quick estimate of the spread of a normal distribution.
Since Shaquana's commute times are normally distributed with a mean of 22 minutes and a standard deviation of 3 minutes, we can use this information to find the interval that represents the middle 95% of her commute times.
To do this, we need to find the range of values that is two standard deviations away from the mean in either direction.
Lower limit = Mean - 2SD = 22 - 23 = 16 minutes
Upper limit = Mean + 2SD = 22 + 23 = 28 minutes
Therefore, the interval that represents the middle 95% of Shaquana's commute times is (16, 28) minutes. This means that we expect Shaquana's commute time to be between 16 and 28 minutes, with 95% confidence.

In order to evaluate 7 sec(θ) dθ, multiply the integrand by sec(θ) + tan(θ) sec(θ) + tan(θ) . 7 sec(θ) dθ = 7 sec(θ) sec(θ) + tan(θ) sec(θ
Answer:
[tex]\int {7 \sec(\theta) } \, d\theta = 7\ln(\sec(\theta) + \tan(\theta)) + c[/tex]
Step-by-step explanation:
The question is not properly formatted. However, the integral of [tex]\int {7 \sec(\theta) } \, d\theta[/tex] is as follows:
[tex]\int {7 \sec(\theta) } \, d\theta[/tex]
Remove constant 7 out of the integrand
[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\sec(\theta) } \, d\theta[/tex]
Multiply by 1
[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\sec(\theta) * 1} \, d\theta[/tex]
Express 1 as: [tex]\frac{\sec(\theta) + \tan(\theta) }{\sec(\theta) + \tan(\theta)}[/tex]
[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\sec(\theta) * \frac{\sec(\theta) + \tan(\theta) }{\sec(\theta) + \tan(\theta)}} \, d\theta[/tex]
Expand
[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\frac{\sec^2(\theta) + \sec(\theta)\tan(\theta) }{\sec(\theta) + \tan(\theta)}} \, d\theta[/tex]
Let
[tex]u = \sec(\theta) + \tan(\theta)[/tex]
Differentiate
[tex]\frac{du}{d\theta} = \sec(\theta)\tan(\theta) + sec^2(\theta)[/tex]
Make [tex]d\theta[/tex] the subject
[tex]d\theta = \frac{du}{\sec(\theta)\tan(\theta) + sec^2(\theta)}[/tex]
So, we have:
[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\frac{\sec^2(\theta) + \sec(\theta)\tan(\theta) }{u}} \,* \frac{du}{\sec(\theta)\tan(\theta) + sec^2(\theta)}[/tex]
Cancel out [tex]\sec(\theta)\tan(\theta) + sec^2(\theta)[/tex]
[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\frac{1}{u}} \,du}}[/tex]
Integrate
[tex]\int {7 \sec(\theta) } \, d\theta = 7\ln(u) + c[/tex]
Recall that: [tex]u = \sec(\theta) + \tan(\theta)[/tex]
[tex]\int {7 \sec(\theta) } \, d\theta = 7\ln(\sec(\theta) + \tan(\theta)) + c[/tex]

hey found that 27 occurred in the Spring, 39 in the Summer, 31 in the Fall, and 53 in the Winter. Can it be concluded at the 0.05 level of significance that car accidents are not equally distributed throughout the year
This question is incomplete, the complete question is;
A Driver's Ed program is curious if the time of year has an impact on numer of car accidents in the U.S.
They assume that weather may have a significant impact on the ability of drivers to control their vehicles. They take a random sample of 150 car accidents and record the seasons each occurred in. They found that 27 occurred in the Spring, 39 in the Summer, 31 in the Fall, and 53 in the Winter. Can it be concluded at the 0.05 level of significance that car accidents are not equally distributed throughout the year
a) Yes, because the p-value = 0.0145
b) No, because the p-value = 0.0145
c) Yes, because the p-value = 0.0291
d) No, because the p-value = 0.0291
Answer:
p-value = 0.0145
Since p-value ( 0.0145 ) is less than Significance level ∝ ( 0.05 ),
We reject Null hypothesis.
Hence, There is sufficient evidence to conclude that car accidents are NOT equally distributed through out the year.
[ Option a) Yes, because the p-value = 0.0145 ] is the correct answer.
Step-by-step explanation:
Given the data in the question;
number of car accident = 150
Observed Frequencies O are;
Spring = 27
Summer = 39
Fall = 31
Winter = 53
Significance level ∝ = 0.05
Hypothesis
Null hypothesis H₀ : The car accidents are equally distributed through out the year
Alternative hypothesis H₀ : The car accidents are NOT equally distributed through out the year
Now, Expected Frequency E will be;
Spring = 150/4 = 37.5
Summer = 150/4 = 37.5
Fall = 150/4 = 37.5
Winter = 150/4 = 37.5
Test Statistics;
[tex]X^2_{stat^[/tex] = ∑[ ( O-E )² / E ]
so
[tex]X^2_{stat^[/tex] = [ ( 27-37.5 )² / 37.5 ] + [ ( 39-37.5 )² / 37.5 ] + [ ( 31-37.5 )² / 37.5 ] + [ ( 53-37.5 )² / 37.5 ]
[tex]X^2_{stat^[/tex] = 2.94 + 0.06 + 1.1267 + 6.4067
[tex]X^2_{stat^[/tex] = 2.94 + 0.06 + 1.1267 + 6.4067
[tex]X^2_{stat^[/tex] = 10.5334
Degree of Freedom DF = n-1 = 4 -1 = 3
Now,
p-value = P( [tex]X^2[/tex] - [tex]X^2_{stat^[/tex] ) = P( [tex]X^2[/tex] - 10.5334 ) = 0.0145
p-value = 0.0145
Since p-value ( 0.0145 ) is less than Significance level ∝ ( 0.05 ),
We reject Null hypothesis.
Hence, There is sufficient evidence to conclude that car accidents are NOT equally distributed through out the year.
[ Option a) Yes, because the p-value = 0.0145 ] is the correct answer.

Answer:
244 tiles
Step-by-step explanation:
These "border" problems can be a little tricky.
The tiles are 1 ft square, so an integer number of them fit along each of the sides. The 40-ft side will take 40 tiles for its border, and the 80-ft side will take 80 tiles.
The total number of tiles along each of the four sides is ...
40 + 80 + 40 + 80 = 240 . . . tiles
However, there is also a tile in each of the corners. There are 4 of those, so the total number of tiles surrounding the pool is ...
240 +4 = 244 tiles
__
Alternate solution
For a border of width w, the outside area of the pool plus the border is ...
A = LW = (80 +2w)(40 +2w) = 80·40 +240w +4w²
The area of the pool is ...
A = LW = (80)(40) = 80·40
Subtracting the area of the pool from the total area including the border gives ...
border area = (80·40 +240w +4w²) -(80·40) = 240w +4w²
We know the width of the border is 1 foot, so w=1 and the border area is ...
border area = 240·1 +4·1² = 244 . . . . square feet
Each tile is 1 square foot, so 244 tiles are needed for the border.
_____
It can help to draw yourself a diagram. It can also help to make a small model using blocks, Scrabble tiles, Legos, jigsaw puzzle pieces, squares cut from paper, or even coins (pennies). Anything that will give you an idea of how to count the tiles required to make a border can be helpful.
