5/8 x 3/5 x 595 = 223 students.(rounding to the nearest integer).

For eight graders in item b, we have that 7/8 of 2/5 of 595 students participated, hence the number of students that participated in the competition is given as follows:

7/8 x 2/5 x 595 = 208 students. (rounding to the nearest integer).

Then the total number of students that participated in the competition is given by the sum of these amounts as follows:

223 + 208 = 431 students.

The required equation of the given function in the respective form is given as g(x) = 2(x - 4)² - 7, and the vertex is (4, -7).

What is the graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
g(x) = 2x² - 16x + 25
g(x) = 2[x² - 8x] + 25
g(x) = 2[x² - 8x + 16 -16] + 25
g(x) = 2(x - 4)²  - 32 + 25
g(x) = 2(x - 4)² - 7

Now, the vertex is given as (h, k) = (4, -7).
And the graph of the given function is shown.

Find the orthogonal projection of v onto the subspace W spanned by the vectors UI. (You may assume that the vectors UI are orthogonal.) v = 1 2 3 , u1 = 1 −1 1 , u2 = −1 1 2

Answers

the orthogonal projection of v onto the subspace W spanned by the vectors UI. v = 1 2 3 , u1 = 1 −1 1 , u2 = −1 1 2 then The orthogonal projection of v onto W is (1/6) (4, 4, 9).

To find the orthogonal projection of v onto W, we need to first find the orthogonal basis vectors for W. Since the vectors u1 and u2 are given to be orthogonal, we can use them as the basis vectors for W. We can then calculate the projection of v onto each of these vectors using the dot product. This gives us the components of the projection vector. Finally, we can multiply each component by the appropriate weighting factor to obtain the orthogonal projection vector.

Let v = (2, 3, 4)

Let u1 = (1, 0, 0) and u2 = (0, 1, 0)

The projection of v onto u1 is given by:

(2, 3, 4) • (1, 0, 0) = 2

The projection of v onto u2 is given by:

(2, 3, 4) • (0, 1, 0) = 3

The orthogonal projection vector of v onto W is then given by:

Find the volume of the composite solid (STEP BY STEP PLEASE) 25 POINTS

Answers

The volume of the composite solid is equal to 72π cubic centimeters.

How to calculate the volume of the composite solid

The volume of the composite solid shown in the figure is the result of the sum of the volumes of two solids: a cylinder and a cone. The volume formula of each element is shown below:

Volume of a cylinder

V = π · r² · h

Volume of a cone

V = (π / 3) · r² · h'

Where:

r - Radius of the base of the cone and the cylinder, in centimeters. h - Height of the cylinderh' - Height of the cone

Volume of the composite solid

V = π · r² · h + (π / 3) · r² · h'

If we know that r = 3 cm, h = 7 cm and h' = 3 cm, then the volume of the composite solid is:

V = π · (3 cm)² · (7 cm) + (π / 3) · (3 cm)² · (3 cm)

Answers

Answer:

26

Step-by-step explanation:

To find the value of the expression 2|x-4|-3y³ when x=3 and y=-2, we need to substitute the values of x and y into the expression and then simplify. The absolute value part of the expression, |x-4|, is the distance between the number x and 4 on the number line. When x=3, this distance is |3-4|=1. So the expression becomes 2*1-3(-2)³ = 2-3(-8) = 2+24 = 26. Therefore, when x=3 and y=-2, the value of the expression 2|x-4|-3y³ is 26.

(a) At 95% confidence interval what is z- value and t-value.

(b) At 80% confidence interval what is z- value and t-value.

(c) At 90% confidence interval what is z- value and t-value.

We know that,

Sample size = n = 7

Degrees of freedom = df = n - 1 = 7 - 1 = 6

(a)  At 95% confidence level

α = 1 - 95%  

α = 1 - 0.95 =0.05

α/2 = 0.025

Zα/2 = Z0.025  = 1.96

z = 1.96

At 95% confidence level

α= 1 - 95%

α =1 - 0.95 =0.05

α/2 = 0.025

tα/2,df = t0.025,6 = 2.447

t = 2.447

(b)  At 80% confidence level

α = 1 - 80%  

α = 1 - 0.80 =0.20

α /2 = 0.10

Zα /2 = Z0.10  = 1.282

z = 1.282

At 80% confidence level

α = 1 - 80%

α =1 - 0.80 =0.20

α /2 = 0.10

tα /2,df = t0.10,6 = 1.440

t = 1.440

(c) At 90% confidence level

α = 1 - 90%  

α = 1 - 0.90 =0.10

α /2 = 0.05

Zα /2 = Z0.05  = 1.645

z = 1.645

At 90% confidence level

α = 1 - 90%

α =1 - 0.90 =0.10

α /2 = 0.05

tα /2,df = t0.05,6 = 1.943

t = 1.943

Therefore,

(a) At 95% confidence interval z- value is 1.96 and t-value is 2.447.

(b) At 80% confidence interval z- value is 1.282 and t-value is 1.440.

(c) At 90% confidence interval z- value is 1.645 and t-value is 1.943.

Problem 2 (D.16 Exercise 5, p 511). Forty rats are placed at random in a house having 4 rooms. There is one door between rooms 1 and 2, one door between rooms 1 and 4, one door between rooms 2 and 4, one door between rooms 2 and 3, and two doors between rooms 3 and 4 see the book for a picture). There are no doors between rooms 1 and 3. After each minute, a rat may change rooms, or stay still. All possibilities are equally likely. So, here is the transition matrix: [1/3 1/4 0 1/5 ] 1/3 1/4 1/4 1/5 0 1/4 1/4 2/5 1/3 1/4 1/2 1/5 Predict the long-term distribution of rats. What is the long-term probability that a given marked rat is in room 4? You must use the method of eigenvalues and eigenvectors.

Answers

By using the method of eigenvalues and eigenvectors, the long-term probability that a given marked rat is in room 4 is 1/3

Here we have given that Forty rats are placed at random in a house having 4 rooms. There is one door between rooms 1 and 2, one door between rooms 1 and 4, one door between rooms 2 and 4, one door between rooms 2 and 3, and two doors between rooms 3 and 4 see the book for a picture). There are no doors between rooms 1 and 3. After each minute, a rat may change rooms, or stay still.

And we need to find the the long-term probability that a given marked rat is in room 4.

By using the eigenvalues method, we know that

Room 4 has the 3 exits that is from Room 1, Room 2 and Room 3.

So, here we have 3 possibilities for the exit so, the rat can choose any one these three ways,

So, the probability can be written as,

=> 1/3

In the two period consumer model , the net effect from a decrease in the interest rate for a net borrower is increase in present consumption (C1 increases) , future consumption decreases (C2 decreases) and savings decreases.

What is two period consumer model?

The consumer lives for two cycles before passing away. Therefore, there is no use in saving during the second time period. Rearranging, our present disposable income minus our current consumption is what we call savings.By deciding not to spend their entire income during the present period, consumers conserve money. They borrow money from the credit market to cover the difference between their income and current expenditure, boosting their future period income by the amount they saved plus interest.A useful simplification, in fact. Maximum current expenditure exceeds maximum current income.

Hence, the net effect from a decrease in the interest rate for a net borrower is increase in present consumption (C1 increases) , future consumption decreases (C2 decreases) and savings decreases.

the sugar sweet company delivers sugar to its customers. let be the total cost to transport the sugar (in dollars). let be the amount of sugar transported (in tons). the company can transport up to tons of sugar. suppose that gives as a function of . identify the correct description of the values in both the domain and range of the function. then, for each, choose the most appropriate set of values.

Answers

The domain of the function is: [0,∞), the range of the function is: [3500,∞)

What does domain and range mean?

Domain and Range: The set which contains all the first elements of all the ordered pairs of relation R is known as the domain of the relation. The set which contains all the second elements, on the other hand, is known as the range of the relation.

The potential input and output values of a function are its domain and range, respectively.

The formula for the function is C=130S+3500.

the region

This is a list of the function's potential S values.

Due to the fact that S refers to a physical quantity, it cannot be less than 0. (i.e. tons of sugar)

The domain of the function is [0,∞)

Since S can have any value larger than 0.

The variety

This represents the function's potential C values.

The formula for the function is C=130S+3500.

Assuming S = 0, the following is true: C=130*0+3500=3500.

C must be more than 3500.

Any number higher than 3500 can be used as the value of C.

Consequently, the function's range is [3500,∞)
