Step-by-step explanation:
A professor of management has heard that seven students in his class of 49 have landed an internship for the summer. Suppose he runs into two of his students in the corridor. a. Find the probability that neither of these students has landed an internship. (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.) b. Find the probability that both of these students have landed an internship. (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)
Answer:
Total = 0.7321 (Approx)
Probability that both got internship = 0.0179 (Approx)
Step-by-step explanation:
1. First student not get internship = (49-7) / 49
First student not get internship = 42 / 49
Second student not get internship = (42-1) / (49-1)
Second student not get internship = 41 / 48
Total = [42 / 49][41 / 48]
Total = 0.7321 (Approx)
2. Probability that both got internship = 7C2/49C2
Probability that both got internship = (7)(6)/(49)(48)
Probability that both got internship = 0.0179 (Approx)
XYZ, Inc. manufactures the same product in two of their plants, a Northern facility and a Southern facility. Customers who purchase from XYZ, Inc. are encouraged to return their products if they are defective. The probability that a customer returns his/her purchased product given that it was manufactured in the Southern facility is 0.15. The Southern facility produces 40% of the products. It has been recorded that 8% of the customers return their product. What is the probability that a product has been manufactured in the Southern facility if it has been returned to XYZ, Inc.
Answer: = 0.75
Step-by-step explanation:
given that;
P ( returned product / southern fac.) = 0.15
probability of being manufactured in Southern facility P(S) = 40% = 0.40
so probability of being manufactured in norther facility P(N) = 0.60
probability of product being returned =P(R) =0.08
therefore P(RnS) = P(S) * P(R|S)
= 0.40 * 0.15
= 0.06
so now the probability that a product has been manufactured in the Southern facility if it has been returned to XYZ
= P(S|R) = P(RnS)/P(R)
= 0.06 /0.08
= 0.75

Answer:
Option (2) and Option (4)
Step-by-step explanation:
From the picture attached,
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
By Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
BC = [tex]\sqrt{(20)^2-(16)^2}[/tex]
= [tex]\sqrt{400-256}[/tex]
= [tex]\sqrt{144}[/tex]
= 12
Now, Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}=\frac{\text{AB}}{\text{AC}}[/tex]
= [tex]\frac{16}{20}[/tex]
Cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}=\frac{\text{BC}}{\text{AC}}[/tex]
= [tex]\frac{12}{20}[/tex]
tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{\text{AB}}{\text{BC}}[/tex]
= [tex]\frac{16}{12}[/tex]
Therefore, Option (2) and Option (4) are the correct options.
The equation that should be used is option 2 and option 4.
Calculation of the equation:Since
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
So here we apply the Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
So,
[tex]BC = \sqrt{(20)^2 - (16)^22}\\\\ = \sqrt{400 - 256}\\\\ = \sqrt{144}[/tex]
= 12
Now
Sin θ = 16\20
Cos θ = 12\20
tan θ = 16 \12
hence, The equation that should be used is option 2 and option 4.

A group of veterinarians at a major veterinary hospital was interested in investigating a possible link between enteroliths (stones that form in the colon of horses) and diet. They decided to conduct a survey of the feeding practices for horses admitted to the veterinary hospital. To obtain a random sample of the 5000 horses that had been admitted to the hospital over the last 10 years, the veterinarians sequentially assigned numbers (starting with 0001) to the horses, in order of admittance. They then picked a random starting point and decided to sample every hundredth horse to get a random sample of 50 horses. This procedure corresponds to:
Answer:
Systematic Sampling
Step-by-step explanation:
The procedure corresponds to systematic sampling because Systematic sampling is a method of probability sampling whereby sample members from a larger population are selected in order of a random starting point but in a fixed, periodic interval.
Now, in the question we are told that they picked a random starting point and decided to sample every hundredth horse to get a random sample of 50 horses. Since random starting point in corresponds to Systematic Sampling.
Another reason why it's a systematic sampling is because they sampled every hundredth horse and therefore not all the samples were considered.

Use the table below to match the slopes to the lines.
Answer: Check out the filled out chart below.
Row 1: 1/4, 1/4, -4
Row 2: -2, -2, 1/2
Row 3: 3, 3, -1/3
=========================================
Explanation:
Parallel lines have equal slopes. So if the original line has slope 1/4, then any parallel line will also have slope 1/4. The only thing different is the y intercept.
Perpendicular slopes multiply to -1 assuming neither line is vertical. For row 1, the perpendicular slope is -4 which multiplies with the original slope 1/4 to get -1.
Put another way, the perpendicular slope is the negative reciprocal of the original slope. For row 2, the perpendicular slope is 1/2 because we flip the fraction and the sign for the original slope -2 = -2/1

One month also rented 5 movies and 3 video games for a total of $31 the next month he rented 7 movies and 9 video games for a total of $71 find the rental cost for each movie and each video game
Answer:
V = 5.75, M = 0.45
Step-by-step explanation:
5M + 3V = 31
7M + 9V = 71
5M = 31 - 3V
M = (31 - 3V) / 5
7((31 - 3V) / 5) + 9V = 71
(217 - 21V)/5 + 9V = 71
43.4 - 4.2V + 9V = 71
4.8V = 27.6
V = 5.75
5M + 3(5.75) = 31
5M = 2.25
M = 0.45

Assume a normal distribution and that the average phone call in a certain town lasted 7 min, with a standard deviation of 1 min. What percentage of the calls lasted less than 6 min?
Answer:
16%
Step-by-step explanation:
First, find the z-score.
z = (x − μ) / σ
z = (6 − 7) / 1
z = -1
Use a chart, a calculator, or the empirical rule to find the probability.
Using the empirical rule:
P(Z < -1) = 0.5 − 0.34
P(Z < -1) = 0.16
The percentage is 16%
How do I calculate a percentage between two numbers?To calculate the share between two numbers, divide one variety by way of the opposite and multiply the end result by way of one hundred, e.g. (30 / 75) * 100. This indicates what percent the first number is of the second one, in the example - 30 is 40% of 75.
In mathematics, a percent is more than a few or a ratio expressed as a fragment of 100. It is regularly denoted using the percentage signal, "%", although the abbreviations "pct.", "pct" and from time to time "pc" also are used. A percentage is a dimensionless number; it has no unit of size.
First, discover the z-rating.
z = (x − μ) / σ
z = (6 − 7) / 1
z = -1
Use a chart, a calculator, or the empirical rule to discover the chance.
using the empirical rule:
P(Z < -1) = 0.5 − zero.34
P(Z < -1) = 0.16

C)The digit 5 in the number 357 represents 100 times as much as it represents in the number 465.
D)The digit 5 in the number 357 represents the same amount as it represents in the number 465.
Answer:
Option B.
Step-by-step explanation:
In this problem, we need to compare digit 5 in the number 357 with the digit 5 in the number 465.
In 357, 5 is on the tens place while in 465 5 is in the ones place.
Place value of 5 in 357 is 50 and in 465 is 5 only.
For comparison, divide 50 by 5. So,
50/5 = 10
It means that the digit 5 in the number 357 represents 10 times as much as it represents in the number 465.

In 1 hr, a plane can travel 390 mi into the wind and 470 mi with the wind. Find the wind speed and the rate of the plane in still air.
The wind speed is mph.
The rate of the plane in still air
mph
Let w be the wind speed and p the plane's speed in still air.
Flying against the wind, the plane has velocity
p - w = 390 mi/h
and flying with it, it has
p + w = 470 mi/h
Add the two equations together to eliminate w and solve for p :
(p - w) + (p + w) = 390 mi/h + 470 mi/h
2p = 860 mi/h
p = 430 mi/h
Subtract them to eliminate p and solve for w :
(p - w) - (p + w) = 390 mi/h - 470 mi/h
-2w = -80 mi/h
w = 40 mi/h

Write a paragraph proof to prove the statement
Answer:
We are given that the sum of the measures of angles A and B is equal to the sum of the measures of angles B and C. The measure of angle B is equal to itself by the reflexive property, so you can subtract that measure from both sides of the equation. Now the measure of angle A equals the measure of angle C. By the symmetric property, this means the measure of angle C equals the measure of angle A.

Find the value of x.
Answer:
x = 5
Step-by-step explanation:
When two straight lines intersect, four angles are formed. The angles that are directly opposite of each other are equal. Since the angles are equal set the values equal to each other and solve for x.
5x - 5 = 2x + 10
5x - 5 - 2x = 2x + 10 - 2x
3x - 5 = 10
3x - 5 + 5 = 10 + 5
3x = 15
3x/3 = 15/3
x = 5
