Answers
Answer: 1625
Step-by-step explanation: So if you want to make 13 of one recipe it said that in 1 recipe there's 125 cups of sugar so you need to multiply 123 by 13 so do this 125 x 13 = 1625 and then there, you have your answer 1,625 cups of sugar for 13 things of the recipe.

A zoologist selected 12 black bears in a Canadian habitat at random to examine the relationship between the age in years, x, and the weight in tens of pounds, y. The 95 percent confidence interval for estimating the population slope of the linear regression line predicting weight in tens of pounds based on the age in years is given by 1.272 + 0.570. Assume that the conditions for inference for the slope of the regression equation are met. Which of the following is the correct interpretation of the interval?
A. We are 95 percent confident that the mean increase in the weight of a black bear for each one-year increase in the age of the bear is between 7.0 and 18.4 pounds.
B. We are 95 percent confident that an increase of one year in the age of an individual black bear will result in an increase in the black bear's weight of between 7.0 and 18.4 pounds.
C. We are 95 percent confident that for every one-year increase in the age of black bears in the sample, the average increase in the weights of those black bears is between 7.0 and 18.4 pounds.
D. We are 95 percent confident that the mean increase in the age of a black bear for each one-pound increase in the weight of the black bear is between 7.0 and 18.4 years.
E. We are 95 percent confident that any sample of 12 black bears will produce a slope of the regression line between 7.0 and 18.4.
Answers
Answer:
A
We are 95 percent confident that the mean increase in the weight of a black bear for each one-year increase in the age of the bear is between 7.0 and 18.4 pounds.
Step-by-step explanation:
The 95 confidence interval given by 1.272±0.570, or (0.702,1.842), estimates the relationship between weight in tens of pounds and age in years. So we are 95 percent confident that the mean increase in the weight of a black bear will be between 7.0 and 18.4 pounds for each one-year increase in the age of the bear.
The correct interpretation of the provided confidence interval is given by:
Option B: We are 95 percent confident that an increase of one year in the age of an individual black bear will result in an increase in the black bear's weight of between 7.0 and 18.4 pounds.
How to interpret confidence interval?Suppose the confidence interval at P% for some parameter's values is given by [tex]x \pm y[/tex]
That means, that parameter's estimated value is P% probable to lie in the interval [tex][x - y, x + y][/tex]
For this case, the regression line predicts weight in tens of pounds based on the age in years.
The 95% confidence interval for that prediction is given to be: [tex]1.272 \pm 0.570[/tex]
That means, the predicted value of weight of a black bear (in tens of pounds) when one year age is incremented is 95% probable to lie in the interval [tex][1.272 - 0.57, 1.272 + 0.57] \approx [0.7, 1.84][/tex]
That is for weight in tens of pounds. Converting it to pounds gives us the interval [tex][7.0, 18.4][/tex] approx.
Note the words "prediction", and "of a bear".
That makes us conclude that:
Option B: We are 95 percent confident that an increase of one year in the age of an individual black bear will result in an increase in the black bear's weight of between 7.0 and 18.4 pounds.
(focus on the "will result in" phrase. It is taking similar to prediction thing. Since we're taking about regression line which tries to fit line for prediction of future output values for input values, thus, we chose second option.)
Thus, the correct interpretation of the provided confidence interval is given by:
Option B: We are 95 percent confident that an increase of one year in the age of an individual black bear will result in an increase in the black bear's weight of between 7.0 and 18.4 pounds.

Describe how you can find the number of solutions of two or more
equations by using the slope and the y-intercept. Use vocabulary terms in
your description.
Answers
Answer:
Suppose we have a system of two linear equations, this can be written as:
y = a*x + b
y = c*x + d
Now, we have 3 possible cases here.
The solutions of the system are the points where the graphs of the linear equations do intersect.
Then, if for example, we have two parallel lines (two parallel lines never intersect) we have no solutions.
And we know that two lines are parallel if they have the same slope and different y-intercept.
Then the system:
y = a*x + b
y = a*x + c
has no solutions.
If we have both equal lines, then the lines intersect in infinitely many points, meaning that we have infinite solutions, then the system:
y = a*x + b
y = a*x +b
has infinite solutions.
And if the lines intersect only one time we have one solution, and this happens when the slopes are different, so the system:
y = a*x + b
y = c*x + d
has only one solution.
Now, if we have more equations:
y = a*x + b
y = c*x + d
y = k*x + n
We have more equations than variables, then this system only has one solution of the 3 lines intersect at the same point, which is really rare.
One case where we have a solution here is if the 3 equations have the same y-intercept:
y = a*x + b
y = c*x + b
y = d*x + b
where the solution is the point (0, b)
Of course, there are other possible solutions, but these are not as formulaic as this ones.

For each pair of functions f and g below, find f(g(x)) and g(f(x)).
Then, determine whether f and g are inverses of each other.
Simplify your answers as much as possible.
(Assume that your expressions are defined for all x in the domain ofthe composition.
You do not have to indicate the domain.)
Answers
Answer:
a) f(g(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
g(f(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
f and g are inverses
b) f(g(x)) = x + 3 + 3 = x + 6
g(f(x)) = x + 3 + 3 = x + 6
f and g are not inverses
Step-by-step explanation:
a)
f(g(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
g(f(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
Since f(g(x)) = g(f(x)) = x, then f and g are inverses
b)
f(g(x)) = x + 3 + 3 = x + 6
g(f(x)) = x + 3 + 3 = x + 6
Since f(g(x)) = g(f(x)) ≠ x, then f and g are not inverses

Write an equation of the line shown with point-slope form.
Answers
Given:
The line passes through the points (2,0) and (4,3).
To find:
The point-slope form of the given line.
Solution:
The point slop form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope and [tex](x_1,y_1)[/tex] is the point.
The line passes through the points (2,0) and (4,3). So, the slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-0}{4-2}[/tex]
[tex]m=\dfrac{3}{2}[/tex]
The slope of the line is [tex]m=\dfrac{3}{2}[/tex] and the point is (4,3). So, the point slope form of the given graphed line is:
[tex]y-3=\dfrac{3}{2}(x-4)[/tex]
Therefore, the point slope form of the given line is [tex]y-3=\dfrac{3}{2}(x-4)[/tex].
whats the answer for y=-[tex]\frac{2}{3}[/tex]x+4 and y=[tex]\frac{1}{3}[/tex]x-2
Answers
Step-by-step explanation:
[tex]y = -\frac{2}{3}x + 4[/tex]
[tex]y = \frac{1}{3}x - 2[/tex]
Since both equations are set equal to [tex]y[/tex], we can take the right-hand side of each equation and set them equal to each other to solve for [tex]x[/tex]:
[tex]-\frac{2}{3}x + 4 = \frac{1}{3}x - 2[/tex]
[tex]-\frac{2}{3}x - \frac{1}{3}x = -2 - 4[/tex]
[tex]-x = -6[/tex]
[tex]x = 6[/tex]
Now we can plug this value into either equation to solve for [tex]y[/tex]:
[tex]y = \frac{1}{3}x - 2[/tex]
[tex]y = \frac{1}{3}(6) - 2[/tex]
[tex]y = 2 - 2[/tex]
[tex]y = 0[/tex]
So the solution to the system of equations is [tex](6, 0)[/tex]

Find a
27
Answers
Answer:
The value of a₂₇ is 788
Step-by-step explanation:
a₁₉ = 548
a₃₃ = 968
Now,
a₁₉ = 548 can be written as
a + 18d = 548 ...(1) and
a₃₃ = 968 can be written as
a + 32d = 968 ...(2)
Now, from equation (2) we get,
a + 32d = 968
a + 18d + 14d = 968
548 + 14d = 968 (.°. a + 18d = 548)
14d = 968 - 548
14d = 420
d = 420 ÷ 14
d = 30
Now, for the value of a put the value of d = 30 in equation (1)
a + 18d = 548
a + 18(30) = 548
a + 540 = 548
a = 548 - 540
a = 8
Now, For a₂₇
a₂₇ = a + 26d
a₂₇ = 8 + 26(30)
a₂₇ = 8 + 780
a₂₇ = 788
Thus, The value of a₂₇ is 788
