Suppose Duarte is one of the ten cities in the air pollution survey. We found that the number of manufacturing enterprises employing 20 or more workers in Duarte is 200, and the annual mean concentration of sulfur dioxide in Duarte is 18 micrograms per cubic meter. What is the residual for the city of Duarte
Answers
Kindly check complete question in the attached picture below.
Answer:
2.2236
Step-by-step explanation:
From the R output given, we can obtain the linear regression model in the form ;
y = bx + c
Intercept, c = 9.4764
Slope, b = 0.0315
x = number of manufacturing enterprise employing 20 or more workers
y = annual mean concentration of Sulphur dioxide
Hence, The regression equation model as obtained from the R output is :
y = 0.0315x + 9.4764
For the city of Duarte;
x = 200
Actual annual mean concentration of Sulphur dioxide is 18 micrograms per cubic meter.
Residual = Actual value - predicted value
Prediction using the regression equation to obtain the predicted annual mean concentration ;
The predicted y value, when x = 200
y = 0.0315(200) + 9.4764
y = 15.7764
The residual, if actual annual concentration = 18
Y residual = 18 - 15.7764 = 2.2236

In a relay race, Jill runs 250 meters in 1.5 minutes. She hands the baton to John, who walks for 3 minutes at a rate of 70 meters per minute. Finally, Suzy sprints the last 100 meters in 15 seconds. What distance is traveled in this relay
Answers
9514 1404 393
Answer:
560 m
Step-by-step explanation:
Jill's distance is given as 250 m.
John's distance can be computed as ...
distance = speed × time = (70 m/min)(3 min) = 210 m
Suzy's distance is given as 100 m.
Then the total distance is ...
250 m + 210 m + 100 m = 560 m
The distance traveled is 560 m in this relay.

y=x-2
Step-by-step explanation:
4-0=4 = (change in y)
2--2=4 = (change in x)
change in y/change in x=4/4=1=x
gradient = x
y=x+c
Subtitute any coordinate
2=4+c
c=-2
so
y=x-2
Answer:
y=x-2
Step-by-step explanation:
Slope Intercept Form
y=x-2
Find Slope using equation below
Chose points I chose 2 as y2 and -2 as y2
4 is x2 and 0 as x1
Slope is 1
now choose a point and plug it in for x and y and plug slope in Equation
I chose (4,2)
2=4+b
subtract 4 by both sides
-2=b
Slope Form
So... y=x-2 is the answer

Answers
Answer:
0.39375 = 39.375% probability that the next book by this publisher captures at most 6.15% of the market
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
The probability of finding a value between c and d is:
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Randomly between 3 and 11% of the market.
This means that [tex]b = 11, a = 3[/tex]
What is the probability that the next book by this publisher captures at most 6.15% of the market?
[tex]P(X < 6.15) = \frac{6.15 - 3}{11 - 3} = 0.39375[/tex]
0.39375 = 39.375% probability that the next book by this publisher captures at most 6.15% of the market

what is the hypotenuse?
Answers
Answer:
he longest side of a right triangle, opposite the right angle.
Step-by-step explanation:
Step 1: Define hypotenuse
In any right triangle, there are two legs and one hypotenuse. The legs are the two sides that intersect to show the right angle. The hypotenuse is the longest side, one that is easily found when using Pythagorean Theorem.
Step 2: Define Pythagorean Theorem
The Pythagorean Theorem can be used to find the hypotenuse, with the formula
a^2+b^2=c^2
The hypotenuse is represented as the letter c, and the legs are shown with a and b. Keep in mind that ^2 is a way to show that a variable is squared.
Step 3: Solve for hypotenuse
To find the hypotenuse, simple use the information above to substitute the variables for numbers. The only variable that will not be filled in is c, as we are trying to find the hypotenuse.
*Rewrite equation*
a^2+b^2=c^2
*Fill in a and b*
16^2+12^2=c^2
*Multiply 16 by 16; Multiply 12 by 12*
256+144=c^2
*Add numbers on the left side of the equation*
400=c^2
*Get c alone on the right side by finding the square root of 400 and c^2*
√400= √c^2
20=c

hour. If an experiment starts out with 680 grams of Element X, write a
function to represent the mass of the sample after t hours, where the rate of
change per minute can be found from a constant in the function. Round all
coefficients in the function to four decimal places. Also, determine the
percentage rate of change per minute, to the nearest hundredth of a percent.

What is radioactive isotope?
Radioisotope, radionuclide, or radioactive nuclide, any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays.
Here, mass decreases by 73% every hour.
Weight of element X is 680 grams.
According to question,
f(t) = 680 (1 - 73%)ⁿ
f(t) = 680 (1 - 0.73)ⁿ
f(t) = 680 X 0.27ⁿ
f(t) = 680 X 0.9778ⁿ
f(t) = 680 X (1 - 0.02322)ⁿ
Thus, the element decay percentage rate of change 2.22% per minute.
