The diagonals of a rhombus measure 8cm and 6cm .what is the length of a side of the rhombud​

The correct option representing possible sum for the long chain is B. 13 3 4 + 15 2 4 = 29 1 4.

Firstly let us convert the mixed fraction to fraction. So, the length of first chain = (13×4)+3/4

Length of first chain = 55/4 inches

Length of first chain = 13.75 inches

Length of second chain = (15×4)+2/4

Length of second chain = 62/4

Second chain length = 15.5 inches

So, total length = length of first chain + length of second chain

Total length = 13.75 + 15.5

Total length = 29.25 inches

Converting the decimal back to mixed fraction -

Total length = 29 1/4 inches

Thus, the correct answer B. 13 3 4 + 15 2 4 = 29 1 4.

Answer:

60

Step-by-step explanation:

Colton is 60 because Polly is 21 and plus 39 is 60.

The probability distribution function of Y = |X| is given by:

P(Y ≤ y) = P(|X| ≤ y) = P(-y ≤ X ≤ y)

Since X ~ N(0, 2), we can use the standard normal distribution to find the probability;

P(Y ≤ y) = P(Z ≤ y/√2) - P(Z ≤ -y/√2)

where Z is a standard normal random variable.

To find E(|X|), we can use the formula:

E(|X|) = √(2/π) * σ

where σ is the standard deviation of X. Since X ~ N(0, 2), σ = √2, so:

E(|X|) = √(2/π) * √2 = √(4/π)

To find Var(|X|), we can use the formula:

Var(|X|) = E(X^2) - E(|X|)^2

Since X ~ N(0, 2), E(X^2) = σ^2 = 2. And we already found E(|X|) = √(4/π), so:

Var(|X|) = 2 - (4/π) = (2π - 4)/π

Therefore, the probability distribution function of Y = |X| is P(Y ≤ y) = P(Z ≤ y/√2) - P(Z ≤ -y/√2), the expected value of |X| is E(|X|) = √(4/π), and the variance of |X| is Var(|X|) = (2π - 4)/π.

Answer:

To find the coordinates of the root of the equation y = 3 + 2x - x^2, we need to find the values of x where y = 0 (because the root is the point where the function intersects the x-axis). So we can set y equal to 0 and solve for x:

0 = 3 + 2x - x^2

Rearranging, we get:

x^2 - 2x - 3 = 0

We can factor the quadratic equation by finding two numbers that add up to -2 and multiply to -3. These numbers are -3 and 1, so we can write:

(x - 3)(x + 1) = 0

This equation is true when either x - 3 = 0 or x + 1 = 0. So the roots of the equation are:

x = 3 or x = -1

Therefore, the coordinates of the roots of the equation y = 3 + 2x - x^2 are (3, 0) and (-1, 0).

The probability of the sum of the two numbers being even can be calculated using the formula for the probability of independent events.
The formula for the probability of independent events is: P(A and B) = P(A) x P(B
In this case, A represents the first die and B represents the second die.

To calculate the probability of the sum being even, we need to consider the possible outcomes for each die that would result in an even sum.
For the first die, there are three possible outcomes that would result in an even sum: 1, 3, and 5. The probability of any of these outcomes occurring is 3/6, or 1/2.
For the second die, there are also three possible outcomes that would result in an even sum: 2, 4, and 6. The probability of any of these outcomes occurring is also 3/6, or 1/2.
Using the formula for the probability of independent events, we can calculate the probability of the sum being even:
P(A and B) = P(A) x P(B) = (1/2) x (1/2) = 1/4

From the information provided, we can write the vertex form equation of the parabola as follows:

First, we need to determine the value of "a" in the equation y = a(x - h)^2 + k, where (h,k) is the vertex and "a" determines the width and direction of the parabola.

The distance between the vertex and the focus is equal to 1/4a, so we can use this to find "a":

1/4a = (41/4 - 10)

1/4a = 1/4

a = 1

A. y causes a. is not applicable in this case, as there is no variable named "a" in the equation.

B. The equation y = 3x - 7 represents a linear relationship between two variables, x and y. As the equation has a slope of 3, it indicates that as the value of x increases by 1, the value of y increases by 3. Therefore, the data are correlated positively.

C. This is incorrect. As mentioned in B, the equation represents a linear relationship between two variables, x and y, which are positively correlated.

D. This is correct. Although the equation represents a linear relationship between x and y, it does not imply causation. It is possible that x causes y, y causes x, or some other variable or variables may be influencing both x and y.

For the first equation, y = 2x + 5, it is already in slope-intercept form. The slope is the coefficient of x, which is 2, and the y-intercept is the constant term, which is 5.

For the second equation, 4x - 3y = 12, we can rearrange it to get it in slope-intercept form by isolating y on one side of the equation. We can do this by subtracting 4x from both sides and then dividing by -3: 4x - 3y = 12 -3y = -4x + 12 y = (4/3)x - 4

The slope is the coefficient of x, which is 4/3, and the y-intercept is the constant term, which is -4. For the third equation, x = 7, there is no y term, so it cannot be written in slope-intercept form and the slope and y-intercept do not exist.

For the fourth equation, 3y = 9, we can rearrange it to get it in slope-intercept form by dividing both sides by 3: 3y = 9 y = 3 The slope is 0, since there is no x term, and the y-intercept is the constant term, which is 3.

A company will make a profit of 63.9%

Here, the cost of making pins = £1.10

the number of pins = 1000

Using unitary method, the total cost for making 1000 pins would be,

= Cost of each pin × Number of pins

= 1.10 × 1000

= £1110

Now we find the number of pins that sold in charities.

35 percent of pins in charities.

Using percentage formula, we find 35% of total number of pins.

= 35% of 1000

= (35/100) × 1000

= 350 pins

This means that 350 pins were sold in charities.

So, the number of pins left = 1000 - 350

                                          = 650 pins

Out of these remaining pins, 60% are sold at £3. 00 each

So, the number of pins sold at £3.00:

= 60% of 650

= (60/100) × 650

= 390

And the selling price of these 390 pins would be:

= 390 × £3.00

= £1170                           .................(1)

40% of 650 pins were sold at £5. 00 for 2

So, using percentage formula the number of pins sold at £5.00 for 2 would be:

= 40% of 650

= (40/100) × 650

= 260

These 260 pins were sold in pairs for £5.

Therefore, number of pairs sold

= 260/2

= 130 pairs

The selling price of these 130 pairs of pins would be,

= 130 × 5.00

= £650                    ...............(2)

Therefore, from (1) and (2) the total selling price would be,

= £1170 + £650

= £1820

So, the Profit would be:

= Selling price - Cost price

= 1820 - 1110

= £710

Now using  we find the profit percentage:

= Profit × 100 / Total cost price

= 710 × 100 / 1110

All of the functions have a constant rate of change since they are linear functions with a slope (rate of change) that is equal to the coefficient of the independent variable. Therefore, all functions have a constant rate of change of their slope.

Option A: y = 6(2) = 12 has a slope of 6, which means it increases by 6 for every unit increase in x.

Option B: y = 2(3) = 6 has a slope of 2, which means it increases by 2 for every unit increase in x.

Option C: y = 3(4) = 12 has a slope of 3, which means it increases by 3 for every unit increase in x.

Option D: y = 4(2) = 8 has a slope of 4, which means it increases by 4 for every unit increase in x.

The next term in the sequence would be -31.

What is Sequence ?

A sequence is a list of numbers or objects that follow a specific pattern or rule. Each number in the sequence is called a term, and the terms can be finite or infinite.

A. {31, 26, 21, 16, 11,...}

To find the common difference (d) between consecutive terms in the arithmetic sequence, we can subtract any term from the term that comes after it. For example, we can subtract 26 from 31 to get:

31 - 26 = 5

Similarly, we can subtract 21 from 26, 16 from 21, and so on:

26 - 21 = 5

21 - 16 = 5

16 - 11 = 5

Since the differences between consecutive terms are all the same, we can conclude that the common difference is d = 5.

To find the next term in the sequence, we can add the common difference (d = 5) to the last term (11):

11 + 5 = 16

Therefore, the next term in the sequence would be 16.

B. {-45, -38, -31, -24, . . .}

To find the common difference (d) between consecutive terms in the arithmetic sequence, we can subtract any term from the term that comes after it. For example, we can subtract -38 from -45 to get:

-45 - (-38) = -7

Similarly, we can subtract -31 from -38, -24 from -31, and so on:

-38 - (-31) = -7

-31 - (-24) = -7

Since the differences between consecutive terms are all the same, we can conclude that the common difference is d = -7.

To find the next term in the sequence, we can add the common difference (d = -7) to the last term (-24):

-24 - 7 = -31

The rate of change is 961.37 gallons/hour. This means that the water level decreases by 961.37 gallons every hour.

In mathematics, comparing two related quantities stated in different units is known as a rate. A rate is the ratio of two distinct values that are gauged in various ways. It is not the same as a unit rate to compare a certain number of units of the first quantity to one unit of the second. In general, the rate can be expressed as the ratio of two quantities with distinct units. With the help of rate, we can create a connection between two otherwise unconnected components. By doing this, we can gain a deeper understanding of a scenario.

Given,

The total amount of water the pool can hold =  9613.7 gallons

The time taken to drain the pool completely = 10 hours

We are asked to find the change in water level per hour of the pool.

This can be called the rate of change.

Rate of change = Total amount of water/ Time taken to drain

                       = 9613.7 / 10 = 961.37 gallons / hour

Therefore the rate of change is 961.37 gallons/hour. This means that the water level decreases by 961.37 gallons every hour.
