The two rectangles are similar. which is the correct proportion for corresponding sides?

The area of the parallelogram formed by the vectors U and V is approximately 76.545 square units.

To calculate the area of the parallelogram formed by the vectors U and V, we can use the cross product of the two vectors.

The magnitude of the cross product will give us the area of the parallelogram.

Provided vectors U = (7, 5, -1) and V = (1, 5, 7), we can calculate the cross product:

U x V = (5*(-1) - 7*5, 7*1 - (-1)*1, (7*5) - (1*5))

     = (-35 - 35, 7 + 1, 35 - 5)

     = (-70, 8, 30)

Now, we can calculate the magnitude of the cross product:

|U x V| = sqrt((-70)^2 + 8^2 + 30^2)

       = sqrt(4900 + 64 + 900)

       = sqrt(5864)

       ≈ 76.545

Answer:

\( V_{weights} =1,243 \: cm^3 \)

Step-by-step explanation:

Radius of weight \( r_1=\frac{20}{2}= 10 \:cm\)

Radius of hole \( r_2=\frac{2}{2}= 1 \:cm\)

Height of weight as well as hole (h) = 2 cm

Volume of weights = (Volume of one weight - volume of hole)

\( \therefore V_{weights} = 2 (\pi r_1^2 h - \pi r_2^2 h)\)

\(\therefore V_{weights} = 2 \pi (r_1^2 - r_2^2 )h\)

\(\therefore V_{weights} = 2 (3.14)(10^2 - 1^2 )2\)

\(\therefore V_{weights} =12.56(100 - 1 )\)

\(\therefore V_{weights} = 12.56(99)\)

\(\therefore V_{weights} =1,243.44\)

\(\therefore V_{weights} \approx 1,243 \: cm^3 \)

Among the options given, the following is not a required assumption for the analysis of variance The populations have equal means.

Definition of Analysis of Variance (ANOVA)Analysis of variance (ANOVA) is a statistical technique used to compare the means of three or more groups of data. ANOVA examines the variation between groups and within groups to determine whether there is a significant difference between them. ANOVA is used in many different areas, including medical research, engineering, and social sciences. The following are some of the essential assumptions required for ANOVA:1. The random variable of interest for each population has a normal probability distribution.2. There are at least two populations under consideration.3. The variance associated with the random variable must be the same for each population. In addition, all populations must have a similar mean. However, this is not a requirement for ANOVA. The populations being compared can have different means. However, the test is carried out to determine whether there is a statistically significant difference between them. Populations have equal means is not a required assumption for the analysis of variance.

The price of the coat after a 40% increase in price will be $77.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

A store pays $55 for a coat. The store marks up the price by 40%. Then the marked price is calculated as,

P = $55 x (1 + 0.40)

P = $55 x 1.40

P = $77

The price of the coat after a 40% increase in price will be $77.

There are (n + 2ⁿ- 1) * 2ⁿ different ways to select talks for inclusion in the book, given that at least one talk is selected.

We know that at least one talk must be selected, so we have two cases to consider: either one or more than one talk is selected.

Case 1: If only one talk is selected, then there are n possible talks to choose from since any participant could have given the selected talk.

Case 2: If more than one talk is selected, then we need to consider the number of talks that could have been selected. There are a total of 2ⁿ - 1 possible non-empty subsets of talks that could have been selected. However, we need to subtract 1 from this number to exclude the case where no talks are selected.

So the total number of ways to select talks for the book is n + 2ⁿ - 2.

Now we need to consider the number of ways to assign talks on Saturday and Sunday. There are 2ⁿ possible ways to assign talks since each participant can give their talk on Saturday or Sunday.

(n + 2ⁿ - 2) * 2ⁿ

However, we need to subtract the case where no talks are selected and included in the book, which is simply 2^n since each talk can be assigned to either Saturday or Sunday. So the final answer is:

(n + 2ⁿ - 2) * 2ⁿ - 2ⁿ = (n + 2ⁿ - 1) * 2ⁿ.

The answer of the given question based on the  arc or angle the answer is the measure of arc BC is 100° degrees.

What is Arc?

In geometry, an arc is  portion of  circle's circumference. It is defined as  curved line that connects two points on circle, called endpoints. An arc is named based on its endpoints.

In the given figure, we see that angle BOC is an inscribed angle and its vertex lies on the center of the circle. By the inscribed angle theorem, the measure of the inscribed angle BOC is equal to one-half the measure of the intercepted arc BC.

Therefore, to find the measure of arc BC, we need to multiply the measure of angle BOC by 2. Since angle BOC is given as 50° degrees, we have:

Measure of arc BC = 2 × Measure of angle BOC

= 2 × 50° degrees

= 100° degrees

Therefore, the measure of arc BC is 100° degrees.

Answer:

2/3 = slope

Step-by-step explanation:

Slope is rise over run. If you look at (3,1), to go to the next point, it goes up 2 (rise) and right 3 (run). so 2/3 would be the slope.

The estimated actual temperature, when the temperature adjusted for wind chill is -35 degrees Fahrenheit, is approximately -6.923 degrees Fahrenheit.

To estimate the actual temperature if the temperature adjusted for wind chill is -35 degrees Fahrenheit, we can use the given formula:

V = -26 + 1.3x, where V represents the temperature adjusted for wind chill and x represents the actual temperature.

We are given that the temperature adjusted for wind chill is -35 degrees Fahrenheit.

Let's substitute this value into the formula and solve for x:

-35 = -26 + 1.3x

To isolate x, we can subtract -26 from both sides of the equation:

-35 + 26 = 1.3x

Simplifying the left side of the equation:

-9 = 1.3x

Now, divide both sides of the equation by 1.3:

-9/1.3 = x

Calculating the value:

x ≈ -6.923

sorry for the poor quality picture

The system of equations that represents the given scenario is a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

Two or more expressions with an Equal sign is called as Equation.

Let a represent the number of adult tickets and c represent the number of children's tickets.

The total number of tickets purchased is 20, so we have:

a + c = 20

The cost of an adult ticket is $15 and the cost of a children's ticket is $10. The total cost of the tickets is $225, so we have:

15a + 10c = 225

Therefore, the system of equations that represents the given scenario is:

a + c = 20

15a + 10c = 225

Now let us solve a and c values by using substitution method.

a=20-c

Now substitute in equation 15a + 10c = 225

15(20-c)+ 10c = 225

300 - 15c + 10c = 225

-5c = -75

c = 15

Substituting c = 15 into the first equation, we get:

a + 15 = 20

a = 5

Therefore, the system of equations that represents the given scenario is

a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

The answer is A. I and IV. The x-axis is a line that runs horizontally and intersects the y-axis at the origin, which is the point (0,0).

The x-axis is used to locate points on a graph, and it is the horizontal line that runs from left to right. It is used to represent the independent variable and is usually labeled x.

This means that statement I is true.

The x-axis is a horizontal number line that passes through the origin, so statement IV is also true.

Statement II is false because the x-axis is a horizontal line, not a vertical line.

Statement III is false because the x-axis is the first coordinate in an ordered pair that describes the horizontal distance from the origin.

The x-axis intersects the y-axis at the origin, which is the point (0,0). It is a horizontal number line that passes through the origin, so statements I and IV are both true.

If the maximum of function r(x) and t(x) occur at the same point c in domain P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

Step-by-step explanation:

If the maximum of function r(x) and t(x) occur at the same point c in domain then M=r(c) and N=t(c) So in this case P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

by definition of maximum  

r(x)≤M,t(x)≤N   for all x in domain

=>  r(x)+t(x)≤M+N   for all x in domain

=> max(r(x)+t(x)) <= M+N

=> P  ≤  M+N

Thus we get in general the relationship is P  ≤  M+N

Answer:

The value of x is 10.

Step-by-step explanation:

By question,

-4(x - 5) = 60

or,-4x + 20 = 60

or,-4x = 60 -20

or, -4x = 40

or, x =40/-4

Hence,x=10

Answer:

x = 10

Step-by-step explanation:

-4(x - 5 ) = 60

Solve for x.

-4(x - 5 ) = 60

Step 1 :- Distribute -4.

-4 × x - 4 × -5 = 60

-4x + 20 = 60

Step 2 :- Move constant to the right-hand side and change their sign.

-4x = 60 - 20

Step 3 :- Subtract 20 from 60.

-4x = 40

Step 4 :- Divide both side by -4.

\( \frac{ - 4x}{ - 4} = \frac{40}{ - 4} \\ \)

Hence , x = 10

Answer: Option 2

The line starts at an x of -4, so the domain is from -4 to infinity since the arrow goes off the graph, meaning it keeps going. The line starts on a y of 2, and the line continues up with the arrow pointing slightly up, so the range is from 2 to infinity.

The domain is from left to right, and the range is down to up

Answer:

2.  {x | x ≥ −4}; {y | y ≥ 2}

Step-by-step explanation:

Let's try to determine the domain first. Look at the x values. The function begins at -4, so our possible domain values also begin at -4, and the values continue positively after -4.

Therefore, our domain is: Domain: {x ≥ -4}.

Or, we could assign our domain using interval notation: [-4,infinity).

Our range, or y values, begin at 2 and continue positively after 2.

Therefore, our range is: Range: {y ≥ 2}.

Again, we could use interval notation to assign our range: [2,infinity)

Therefore, the answer would be

Answer:

Total number of jars will be 15.          

Step-by-step explanation:

Given

The weight of each marble = 1/25 pound

The weight of all marbles = 3/5 pound

To determine

How many marbles are in the jar?

Let 'n' be the total number of jars

The total number of jars can be calculated by dividing the weight of all marbles by the weight of each marble.

Thus,

The total number of jars n = [weight of all marbles] / [weight of each marble]

                                           = [3/5] / [1/25]

                                           = [3 × 25] / [5 × 1]

                                           = 75 / 5

                                           = 15

Thus, total number of jars will be: n = 15
