Answer:
The probability that it will rain in all 3 cities on that day
P(V∪ C∪S) = 0.93 = 93%
Step-by-step explanation:
Let 'V' be the event of rain in Vancouver
Given that the probability of rain in Vancouver
P( V) = 20% = 0.20
P( V⁻) = 1- P( V) = 1 - 0.20 =0.80
Let 'C' be the event of rain in Calgary
Given that the probability of rain in Calgary
P( C) = 65% = 0.65
P( C⁻) = 1- P( C) = 1 - 0.65 =0.35
Let 'S' be the event of rain in Saskatoon
Given that the probability of rain in Saskatoon
P( S) = 75% = 0.75
P( S⁻) = 1- P( S) = 1 - 0.75 =0.25
First we will prove that the probability that it will not rain in all 3 cities on that day
P( V⁻ ∩ C⁻ ∩ S⁻ ) = P( V⁻) P( C⁻) P(S⁻)
= 0.80 × 0.35 × 0.25
= 0.07
The probability that it will rain in all 3 cities on that day
P(V∪ C∪S) = 1-(P( V⁻ ∩ C⁻ ∩ S⁻ )
= 1 - 0.07
= 0.93

Joseph is reading a 32 page book he read 6 pages in 15 minutes if he continues to read at the same rate how long will it take him to read the entire book
Answer:
80 minutesssssss
Answer:
(edit) your answer is 80 min
Step-by-step explanation:
first we can set this up as a proportion.
so it would be 15 over 6 and your other side would be x over 32
so when u cross multiple your equation would be 6x = 480
then you divide both sides by 6 and when you divide 480 by 6 u will get 80
A traveler flies from Charlotte, North Caroline to Los Angeles, California. At the same time, another traveler flies from Lost Angeles to Charlotte. The air speed of each plane is the same. The ground speed of the first plane is 550 mi/ hour and the ground speed of the second plane is 495 mi/hr. What is the air speed? What is the wind speed? Step 1: Write a system of equations Step 2: Choose a method to solve the system BE GOOD IN THE ANSWER
Answer:
Air speed of planes is 522.5 mi/hr,Wind speed is 27.5 mi/hr.----------------------------------
Let the air speed of the planes be s and the speed of the wind be w.
The two equations are:
550 - w = s495 + w = sAdd up the two equations, it will eliminate w and we'll solve it for s:
550 + 495 = s + s1045 = 2ss = 1045/2s = 522.5The air speed of planes is 522.5 mi/hr.
Find the wind speed:
550 - w = 522.5w = 550 - 522.5w = 27.5The wind speed is 27.5 mi/hr.

The area of a circle is 4π cm². What is the circumference, in centimeters? Express your answer in terms of π pie
Answer:
The formula for the area of a circle is:
A = πr^2
where A is the area and r is the radius.
In this case, we are given that the area is 4π cm². Solving for the radius, we get:
4π = πr^2
r^2 = 4
r = 2
So the radius of the circle is 2 cm.
The formula for the circumference of a circle is:
C = 2πr
Plugging in the value for the radius, we get:
C = 2π(2) = 4π
Therefore, the circumference of the circle is 4π cm.

3 of 25 After running a coiled tubing unit for 81 minutes, Tom has 9,153 feet of coiled tubing in the well. After running the unit another 10 minutes, he has 10,283 feet of tubing in the well. His call sheet shows he needs a total of 15,728 feet of tubing in the well. How many more feet of coiled tubing does he need to run into the well? feet 4 of 25 Brendan is running coiled tubing in the wellbore at a rate of 99.4 feet a minute. At the end of 8 minutes he has 795.2 feet of coiled tubing inside the wellbore. After 2 more minutes he has run an additional 198.8 feet into the wellbore. How many feet of coiled tubing did Brendan run in the wellbore altogether? 5 of 25 Coiled tubing is being run into a 22,000 foot wellbore at 69.9 feet per minute. It will take a little more than 5 hours to reach the bottom of the well. After the first four hours, how deep, in feet, is the coiled tubing? feet
3) The extra number of feet of coiled tubing Tom needs to run into the well is: 5445 ft
4) The total length of coiled tubing Brendan ran in the wellbore is: 994 ft
5) The distance that the coiled tubing has reached after the first four hours is: a depth of 16,776 feet in the well.
How to solve Algebra Word Problems?3) Initial amount of coiled tubing he had after 81 minutes = 9,153 feet
Amount of tubing after another 10 minutes = 10,283 feet
The total tubing required = 15,728 feet.
The extra number of feet of coiled tubing Tom needs to run into the well is: Needed tubing length - Current tubing length
15,728 feet - 10,283 feet = 5,445 feet
4) Speed at which Brendan is running coiled tubing = 99.4 feet per minute.
Coiled tubing inside the wellbore after 8 minutes is: 795.2 feet
Coiled tubing inside the wellbore after 2 more minutes is: 198.8 feet
The total length of coiled tubing Brendan ran in the wellbore is:
Total length = Initial length + Additional length
Total length = 795.2 feet + 198.8 feet
Total Length = 994 feet
5) Rate at which coiled tubing is being run into a 22,000-foot wellbore = 69.9 feet per minute. After the first four hours, we need to determine how deep the coiled tubing has reached.
A time of 4 hours is same as 240 minutes
Thus, the distance covered in the first four hours is:
Distance = Rate * Time
Distance = 69.9 feet/minute * 240 minutes
Distance = 16,776 feet

Pre-paid calling cards are billed in 1-minute increments, rounded down to the nearest minute. MTCC charges 4¢ per minute with a 1-minute billing increment. For long distance calls there is a 50¢ charge and is twice the price. What is the total cost, in dollars, of a long distance phone call that is 32.4 minutes long?
The total cost of a long-distance phone call that is 32.4 minutes long is $1.32.
To calculate the cost, we need to consider two components: the per-minute charge and the additional long-distance charge. The per-minute charge is 4¢ per minute, and since the billing increment is 1 minute, we round down the call duration to the nearest minute, which in this case is 32 minutes. Therefore, the cost for the per-minute charge is 32 minutes × 4¢/minute = $1.28.
In addition to the per-minute charge, there is a flat long-distance charge of 50¢, which is twice the per-minute charge. So, the long-distance charge is $1.28 × 2 = $2.56.
Adding the per-minute charge and the long-distance charge, we get $1.28 + $0.50 = $1.78.
Therefore, the total cost of the long-distance phone call that is 32.4 minutes long is $1.78.

Consider the multiple linear regression Y = B0 + B1 X + B2 Z + B3 W + u, where X is a variable of interest and Z and W are control variables, and where all coefficients are not equal to 0. Suppose
that E[XIWI and EIZWI are constant values. Would the coefficient estimates for B1 and B2 from an alternative regression with Y as the
dependent variable and X and Z as independent variables suffer from omitted variable bias?
The alternative regression with Y as the dependent variable and X and Z as independent variables would suffer from omitted variable bias.
Omitted variable bias is the bias that occurs when a regression model omits one or more relevant variables.
The bias resulting from the omitted variable will influence the coefficients of the other variables in the regression equation.
As a result, the omitted variable bias is the difference between the real coefficients of the variables and the coefficients produced by the regression equation.
The effect of omitted variables on the coefficients is that the coefficients become biased and lose their efficiency.
Therefore, the coefficient estimates for B1 and B2 from an alternative regression with Y as the dependent variable and X and Z as independent variables would suffer from omitted variable bias.
In other words, the missing variable W will have an impact on both X and Z, causing the coefficients of the independent variables to be biased in the alternative regression with Y as the dependent variable and X and Z as independent variables.
As a result, the coefficients in the regression equation will be flawed, and the model will have a significant impact on the data and results produced.
Thus, the alternative regression with Y as the dependent variable and X and Z as independent variables would suffer from omitted variable bias.

what is the image point of (8,-7) after a translation right 1 unit and up 4 units?
Answer:
It is (9,-3) because x increased by 1 unit and y increased by 4 units.
Answer:
\((9,-3)\)
Step-by-step explanation:
\((8,-7)\)
If it moves right, add the value to the x-coordinate. If it moves left, subtract the value from the x-coordinate. In this case, because the point was translated 1 unit right, we add 1 to the x-coordinate 8.
\((9,-7)\)
If it moves up, add the value to the y-coordinate. If it moves down, subtract the value from the y-coordinate. In this case, because the point was translated 4 units up, we add 4 to the y-coordinate.

Consider results of 20 randomly chosen people who have run a marathon. Their times, in minutes, are as follows: 137, 143, 153, 162, 168, 176, 190, 192, 196, 203, 218, 223, 236, 243, 252, 269, 271, 276, 283, 287. Calculate a 99% upper confidence bound on the mean time of the race. Assume distribution to be normal. Round your answer to the nearest integer (e.g. 9876). u
According to the question we have the 99% UCB on the mean time of the race is 223.
The formula for finding the upper confidence bound (UCB) is UCB = Mean + (Zα/2)(σ/√n), where Mean is the sample mean, Zα/2 is the z-score for the desired level of confidence, σ is the population standard deviation (which is not given, so we'll use the sample standard deviation instead), and n is the sample size.
We are given the sample of times as follows:137, 143, 153, 162, 168, 176, 190, 192, 196, 203, 218, 223, 236, 243, 252, 269, 271, 276, 283, 287.
We'll need to calculate the sample mean and standard deviation before we can find the UCB. Using a calculator, we get: mean ≈ 207.65s ≈ 48.41 Next, we'll use a table or calculator to find the z-score for a 99% confidence interval, which is Zα/2 = 2.576.
Now we can plug in the values we know to get the UCB:UCB = mean + (Zα/2)(σ/√n)UCB ≈ 207.65 + (2.576)(48.41/√20)UCB ≈ 223.02 .Therefore, the 99% UCB on the mean time of the race is 223.

(a)in how many ways can the event planner choose 9 dishes if the number of hot dishes must be greater than or equal to 7? (b)in how many ways can the event planner choose 9 dishes if the number of hot dishes must be less than 7?
Part a: There are 4735 ways in which the event planner can choose 9 dishes if the number of hot dishes must be greater than or equal to 7
Part b: There are 91963 ways in which the event planner chooses 9 dishes if the number of hot dishes must be less than 7
Number of cold dishes = 9
Number of hot dishes = 10
Total number of dishes = 19
Part a:
The number of ways 9 dishes can be chosen, given the number of hot dishes, must be greater than or equal to 7:
= (¹⁰C₇*⁹C₂) + (¹⁰C₈*⁹C₁) + ¹⁰C₉
= 4320 + 405 + 10
