A plane flew at a constant speed and traveled
762
762762 miles in
5
55 hours.
How many miles would the plane travel in
3
33 hours at the same speed?
Answers
Therefore, at the same constant speed, the plane would travel approximately 507,406.89 miles in 3.33 hours.
To determine the number of miles the plane would travel in 3.33 hours at the same constant speed, we can use a proportion based on the given information.
The plane traveled 762,762 miles in 5 hours. We can set up the proportion:
762,762 miles / 5 hours = x miles / 3.33 hours
To solve for x (the number of miles traveled in 3.33 hours), we cross-multiply and divide:
(762,762 miles) * (3.33 hours) = (5 hours) * x miles
2,537,034.46 miles = 5x miles
Dividing both sides of the equation by 5:
2,537,034.46 miles / 5 = x miles
x ≈ 507,406.89 miles

Answers
The spider walked 23.6 inches farther on her return walk.
To calculate this, we can use the Pythagorean theorem to find the length of the diagonal from the top back right corner to the front left corner.
a² + b² = c²where a = 8 inches (height), b = 15 inches (length), and c is the length of the diagonal.
c² = 8² + 15²
c² = 64 + 225
c² = 289
c = √(289)
c = 17
So, the length of the diagonal is 17 inches. The spider walks down this diagonal to get to the front left corner, so she walks 17 inches on her return walk. However, she also walked along the bottom of the box for a distance of 6 inches.
Therefore, the spider walked 17 + 6 = 23 inches farther on her return walk. Rounded to the nearest tenth of an inch, the answer is 23.6 inches.

(n 2
) and P N 3
(n 3
). (d) What are the chances that none of the three random variables are equal to 1 ?
Answers
(a) The two-dimensional joint PMF P(N1, N2)(n1, n2) is:
P(N1 = 1, N2 = n2) = (1/n2) * (1/3)P(N1 = 2, N2 = n2) = (1/n2) * (1/3)P(N1 = 3, N2 = n2) = (1/n2) * (1/3)(b) The three-dimensional joint PDF P(N1, N2, N3)(n1, n2, n3) is:
P(N1 = 1, N2 = n2, N3 = n3) = (1/n2) * (1/n2) * (1/3)P(N1 = 2, N2 = n2, N3 = n3) = (1/n2) * (1/n2) * (1/3)P(N1 = 3, N2 = n2, N3 = n3) = (1/n2) * (1/n2) * (1/3)(c) The marginal PDFs P(N2)(n2) and P(N3)(n3) are both equal to 1/n2.
(d) The chances that none of the three random variables are equal to 1 is (1/3) * (1 - 1/n2).
In probability theory, the two-dimensional joint distribution or joint probability distribution refers to the probability distribution of two random variables considered together. It describes the probabilities of different combinations or pairs of outcomes for the two variables.
(a) To find the joint PMF P(N1, N2)(n1, n2), we need to determine the probability of the specific values of N1 and N2 occurring.
Given that N1 = n1, the random variable N2 is equally likely to take on any integer from 1 to n1. Therefore, the probability of N2 = n2, given N1 = n1, is:
P(N2 = n2 | N1 = n1) = 1 / n1
Since N1 can take on values {1, 2, 3} and N2 can take on values {1, 2, ..., n1}, we have:
P(N1 = 1, N2 = n2) = P(N2 = n2 | N1 = 1) * P(N1 = 1) = (1/n2) * (1/3)
P(N1 = 2, N2 = n2) = P(N2 = n2 | N1 = 2) * P(N1 = 2) = (1/n2) * (1/3)
P(N1 = 3, N2 = n2) = P(N2 = n2 | N1 = 3) * P(N1 = 3) = (1/n2) * (1/3)
(b) To find the three-dimensional joint PDF P(N1, N2, N3)(n1, n2, n3), we extend the above probabilities to include the third random variable N3.
Given that N2 = n2, the random variable N3 is equally likely to take on any integer from 1 to n2. Therefore, the probability of N3 = n3, given N2 = n2, is:
P(N3 = n3 | N2 = n2) = 1 / n2
Since N1 can take on values {1, 2, 3}, N2 can take on values {1, 2, ..., n1}, and N3 can take on values {1, 2, ..., n2}, we have:
P(N1 = 1, N2 = n2, N3 = n3) = P(N3 = n3 | N2 = n2) * P(N2 = n2 | N1 = 1) * P(N1 = 1) = (1/n2) * (1/n2) * (1/3)
P(N1 = 2, N2 = n2, N3 = n3) = P(N3 = n3 | N2 = n2) * P(N2 = n2 | N1 = 2) * P(N1 = 2) = (1/n2) * (1/n2) * (1/3)
P(N1 = 3, N2 = n2, N3 = n3) = P(N3 = n3 | N2 = n2) * P(N2 = n2 | N1 = 3) * P(N1 = 3) = (1/n2) * (1/n2) * (1/3)
(c) The marginal PDF P(N2)(n2) can be obtained by summing the joint probabilities over all possible values of N1:
P(N2 = n2) = P(N1 = 1, N2 = n2) + P(N1 = 2, N2 = n2) + P(N1 = 3, N2 = n2)
= (1/n2) * (1/3) + (1/n2) * (1/3) + (1/n2) * (1/3)
= (1/n2)
Similarly, the marginal PDF P(N3)(n3) can be obtained by summing the joint probabilities over all possible values of N1 and N2:
P(N3 = n3) = P(N1 = 1, N2 = 1, N3 = n3) + P(N1 = 1, N2 = 2, N3 = n3) + ... + P(N1 = 3, N2 = n2, N3 = n3)
= (1/n2) * (1/n2) * (1/3) + (1/n2) * (1/n2) * (1/3) + ... + (1/n2) * (1/n2) * (1/3)
= (1/n2)² * (1/3) * n2
= (1/3)
(d) The chance that none of the three random variables are equal to 1 can be found by summing the joint probabilities where N1, N2, and N3 are not equal to 1:
P(N1 ≠ 1, N2 ≠ 1, N3 ≠ 1) = P(N1 = 2, N2 = 2, N3 = 2) + P(N1 = 2, N2 = 2, N3 = 3) + ... + P(N1 = 3, N2 = n2, N3 = n2)
From the joint PDF in part (b), we can see that all probabilities where N1, N2, and N3 are not equal to 1 have the form (1/n2) * (1/n2) * (1/3).
Therefore, the chances that none of the three random variables are equal to 1 is:
P(N1 ≠ 1, N2 ≠ 1, N3 ≠ 1) = (1/n2) * (1/n2) * (1/3) + (1/n2) * (1/n2) * (1/3) + ... + (1/n2) * (1/n2) * (1/3)
= (1/n2)² * (1/3) * (n2 - 1)
= (1/3) * (1 - 1/n2)

The error Hector made is that he placed Puppy 3 at -3.4 instead of at -0.75, which aligns with option A.
From the given options, it appears that the error Hector made is represented by option A: He placed Puppy 3 at -3.4 instead of at -0.75.
To determine this, let's examine the given information about the placements of the puppies on the number line:
Puppy 1: Between 15 and 16
Puppy 2: Between 3 and 3.5
Puppy 3: At -3.4
Puppy 4: Between -6 and -5.5
Puppy 5: To the left of 0
Looking at these placements, we can see that options B, C, and D do not correspond to the given information. Hector correctly placed Puppy 5 to the left of 0, and Puppy 1 between 15 and 16.
However, option A states that Hector placed Puppy 3 at -3.4 instead of at -0.75. This suggests an error in Hector's placement because -0.75 is the correct placement for Puppy 3, not -3.4.
Therefore, the error Hector made is that he placed Puppy 3 at -3.4 instead of at -0.75, which aligns with option A.

Answers
The denominator in the earnings per share formula is number of common shares outstanding.
What is the denominator used in the computation of earnings per share?
The weighted average of the outstanding shares of common stock serves as the numerator of the earnings per share. The "per share" part necessitates further computation when the number of common shares changes in the middle of the year. The weighting of the per share part depends on how long each share number has been in circulation.How are basic earnings per share determined?
Basic EPS is calculated by dividing net income by the weighted average of the common shares outstanding for the relevant period. Preferred dividends should be removed from the net income because they are not available to common stockholders. Net income can also be broken down into "continuing operations" P&L and "total P&L".Learn more about Basic EPS

which exponential equation is equivalent to this logarithmic equation?log2x=24
Answers
Reason:
The log equation \(\log_{b} (y) = x\) is equivalent to the exponential equation \(y = b^x\)
For each equation, the 'b' is the base. Logs are useful to isolate the exponent, and they have other applications as well.
So this is why \(\log_2(x) = 24\) turns into \(2^{24} = x\)

Final Conclusion : which implies that population proportion is different from

There is enough evidence to support to the claim that selection of people is biased against allowing this ethnicity to sit on the grand jury.
We have problem of proportion and we have to apply hypothesis testing in it .
We claim that the selection is biased against allowing this ethnicity to sit on the grand jury. This means that proportion of people of enthic selected for jeury in a way below from proportion that eligible for jury .
Null and Alternative hypothesis are
Hₒ: π= 0.79
Hₐ : π> 0.79
The significance level is 0.01
The sample we will use is total of 876 people that were selected for grand jury duty (n= 876). 42% of them were entnicity for which we are testing , so sample proportion is p= 0.42
The standard error is
σₚ= s√ (π(1-π)/n)= √ 0.79 (1-0.79)/ 876 = √0.00019 = 0.0137~ 0.014
Then we can calculate Z – value
Z = (p-π+0.5/n)/ σₚ =( 0.42 – 0.79 + 0.5/876 )/ 0.014 = - 0.03964/0.014 = - 26.387
P-value for this test statistic is 0
P-value (z<-26.38)= 0
P-value = 0 < 0.01
As we see that P-value is less lower then significance level . This sample result is unpredictable. The null hypothesis is rejected which implies that population proportion is different from π= 0.79
This sample proportion can not be product of chance.

a car traveling at 3030 feet per second decelerates at 2020 feet per second per second. how long does it take for the car to come to a complete stop?
Answers
Therefore, it will take the car 1.5 seconds to come to a complete stop.
To determine the time it will take for the car to come to a complete stop, you can use the formula:
vf = vi + at, where
vf = final velocity,
vi = initial velocity,
a = acceleration
t = time
To use this formula, first, you need to determine the initial velocity and the final velocity.
Since the car is coming to a complete stop, the final velocity will be 0.
Therefore:
vf = 0The initial velocity is given as 30 feet per second.
vi = 30 feet per second
You also know that the car is decelerating at a rate of 20 feet per second per second.
Therefore:
a = -20 feet per second per second
Note that acceleration is negative because it is a deceleration.
Substituting the known values into the formula, you have:0 = 30 - 20tt = 30/20t = 1.5 seconds
Therefore, it will take the car 1.5 seconds to come to a complete stop.
