The volume of the figure that was created by the triangle being rotated, would be 94. 83 units ³

When a triangle is rotated about y = x, a right circular cone is created. The formula is:

= π r² h / 3

We need to find the height and radius. The coordinates for the right circular cone are:

(0,0) - (0,0)

(8,8) - (8,8)

(4,12) - (12,4)

Using this, we find that the radius is 4 units. The height can be found by using any point such as ( 12, 4).

= √ ( ( 12 - 8) ² + ( 4 - 8 ) ²)

= 5. 66 units

The volume would therefore be:

= π x 4² x 5. 66 / 3

= 94. 83 units ³

To find the probability that the drug will wear off in less than 200 minutes:

The z-score is (200-240)/40 = -1.

Using a standard normal distribution table or calculator, P(z < -1) = 0.1587. Therefore, the requested probability is P(x < 200) = 0.1587.

To find the probability that the drug will wear off after 220 minutes:

The z-score is (220-240)/40 = -0.5.

Using a standard normal distribution table or calculator, P(z < -0.5) = 0.3085. Therefore, the requested probability is P(x > 220) = 0.3085.

To find the probability that the drug will wear off between 200 and 220 minutes:

Using the z-scores calculated above, find the area between them on the standard normal distribution. P(-1 < z < -0.5) = 0.1867.

Therefore, the requested probability is P(200 < x < 220) = 0.1867.

The converse statement is of the conditional  “If p then q” is the one in option B.

if q then p.

For two given propositions p and q, a conditional statement is written as:

"if p, then q"

So, if the proposition p is true, also is the proposition q.

The converse statement just changes the order of the two propositions ( if the proposition q is true, also is the proposition p), then here start with q and end with p, so the converse statement is:

if q then p.

Mandy's solution makes sense since it entails multiplying the total number of persons in those entire rows (142) by the number of people in each row (ten).

Similarly, multiplying the total number of people in the remaining seats (142) by the number of people in each row (2) yields the total number of people in the remaining seats. The total number of persons in the theater is calculated by adding these two components.

This is a viable use of multiplication's distributive property, in which we break down a multiplication issue into simpler products and then add them up. As a result, Mandy's approach is a viable method for determining the total number of people in the theater.

The bond yield is approximately 5.0% to the nearest tenth of a percent.

We have,

To find the total cost of the 10 State Farm bonds, we can multiply the price per bond by the number of bonds:

10 bonds x $99.40 per bond = $994.00

So, we paid $994.00 for the 10 State Farm bonds.

To calculate the amount of interest we will receive each year from the bonds, we can use the following formula:

Interest = Principal x Rate

where:

The principal is the amount invested in the bonds

Rate is the interest rate

In this case, our principal is $994.00 and our rate is 5%, or 0.05 as a decimal.

So, the annual interest we will receive from the bonds is:

Interest = $994.00 x 0.05 = $49.70

So,

We will receive $49.70 in interest each year from the bonds.

To calculate the bond yield, we need to use the following formula:

Bond yield = (Annual interest / Total cost) x 100%

In this case, the annual interest is $49.70 and the total cost is $994.00, so we can plug these values into the formula:

Bond yield = ($49.70 / $994.00) x 100% ≈ 5.0%

Therefore,

The bond yield is approximately 5.0% to the nearest tenth of a percent.

For any matrices A and B, where A is a m x n matrix and B is a n x p matrix, the inequality rank(AB) ≤ min rank(A), rank(B) holds.

To see why this is so, examine the rank of a matrix, which is defined as the matrix's greatest number of linearly independent rows or columns.

In other words, it is the dimension of the vector space covered by the matrix's rows or columns.

When we multiply matrices A and B to obtain AB, we get a matrix with m rows and p columns.

The dot product of a row from A and a column from B yields each element in the matrix.

Because the rows and columns of AB are linear combinations of the rows and columns of A and B, the rank of AB is at most the minimum of the rank of A and the rank of B.

If either A or B has a lower rank than the other, there will be some linear dependency between the rows or columns of one of the matrices, which will carry over to AB. This indicates that AB's rank will be strictly less than the bigger matrix's rank.

The value of R² (coefficient of determination) is 0.0214

We know that the formula for the coefficient of determination is,

R² = 1 - (SSR / SST)

where, R² is  the coefficient of determination

SST is the total sum of squares

SSR is the sum of squares of regression

Here, the total sum of squares (SST) = 11654

and the sum of squares of regression (SSR) = 11405

Using above formula,

R² = 1 - (SSR / SST)

R² = 1 - (11405 / 11654 )

Answer: hmm this question is based on 6-80 and if you calulate the sum and difference it is -74

Answer:

g(f(4)) = 106.

Step-by-step explanation:

To find f(g(4)), we first need to find

g(4):g(4) = 5(4)^2 - 4(4) + 1 = 80 - 16 + 1 = 65

Now that we know g(4) is 65, we can find

f(g(4)):f(g(4)) = f(65) = 2(65) - 3 = 127

Therefore,

f(g(4)) = 127.

To find g(f(4)), we first need to find f(4):f(4) = 2(4) - 3 = 5

Now that we know f(4) is 5, we can find g(f(4)):

g(f(4)) = g(5) = 5(5)^2 - 4(5) + 1 = 125 - 20 + 1 = 106

Therefore, g(f(4)) = 106.

Answer:

Step-by-step explanation:

Considering the definition of right rectangular prism and its volume,  the total weight of the contents is 38.81 pounds.

Right rectangular prism

A right rectangular prism (or cuboid) is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and equal two to two.

Volume of right rectangular prism

To calculate the volume of the rectangular prism, it is necessary to find the product of its dimensions, or of the three edges that converge at a certain vertex.

That is, to calculate the volume of a rectangular prism, multiply its 3 dimensions: length×width×height.

Volume of the container

In this case, you know that:

the dimensions of the container built are 7.5 ft by 11.5 ft by 3 ft.

So, the volume of the container is calculated as:

7.5 ft× 11.5 ft× 3 ft= 258.75 ft³

Then, the total weight of the contents is calculated as:

258.75 ft³×  0.15 pounds per cubic foot= 38.8125 pounds≅ 38.81 pounds

The requreid, the joint probability function f(x, y) is:

f(0,0) = 3/14

f(0,1) = 9/28

f(0,2) = 3/28

f(1,0) = 9/28

f(1,1) = 9/28

f(2,0) = 3/14

f(2,1) = 3/14

f(3,0) = 1/14

To evaluate the joint probability function f(x, y), we need to determine the probability of selecting x black balls and y blue balls out of a sample of 4 balls. We can do this using the hypergeometric probability distribution formula:

f(x,y) = P(X = x, Y = y) = (C(3, x) * C(2, y) * C(3, 4-x-y)) / C(8, 4)

where C(n, k) represents the number of combinations of k items chosen from a set of n items.

Plugging in the values, we get:

f(0,0) = (C(3,0) * C(2,0) * C(3,4-0-0)) / C(8,4) = 3/14

f(0,1) = (C(3,0) * C(2,1) * C(3,4-0-1)) / C(8,4) = 9/28

f(0,2) = (C(3,0) * C(2,2) * C(3,4-0-2)) / C(8,4) = 3/28

f(1,0) = (C(3,1) * C(2,0) * C(3,4-1-0)) / C(8,4) = 9/28

f(1,1) = (C(3,1) * C(2,1) * C(3,4-1-1)) / C(8,4) = 9/28

f(2,0) = (C(3,2) * C(2,0) * C(3,4-2-0)) / C(8,4) = 3/14

f(2,1) = (C(3,2) * C(2,1) * C(3,4-2-1)) / C(8,4) = 3/14

f(3,0) = (C(3,3) * C(2,0) * C(3,4-3-0)) / C(8,4) = 1/14

The rim of the basketball hoop is 10 feet high, which is equal to 120 inches .

To find out how many feet Chase has to jump to touch the rim, we need to subtract his reach from the height of the rim:

120 inches (height of rim) - 88 inches (Chase's reach) = 32 inches

So Chase has to jump 32 inches to touch the rim. To convert this to feet, we can divide by the number of inches in a foot:
