Given y = 2 |3 - 7x| + 4, which set describes x when y < 10?

The class limit of the given data is the actual values from the data that represents the lower values and the larger values of a data set. While the class boundaries represents the values that eliminate gaps between the classes in the frequency distribution which are one decimal place more accurate than the data.

To determine the class limit, using a class interval of 5.00, the following should be carried out;

The lowest figure from the given data set = 48.6. Therefore, the lower class interval should start from a figure lower than 48.6 such as = 45.0

Answer:

Cost of Washer = $696

Cost of Dryer = $232

Step-by-step explanation:

Start by making and equation, put a variable for the missing prices, let's say the cost of the dryer is 'x' and since the cost of the washer is three times, it will be '3x'.

Put the equation together, so we can add the x variables together.

3x + x = 4x

The total cost will be what the '4x' is equal to.

4x = 928

Going back to algebra, we solve the equation by dividing both sides by 4.

x = 232

Remember x is the variable we gave to the dryer, so now we must find the cost of the washer. In order to do this, we will have to multiply it by 3.

3x

3(232) = 696.

To check the answer, we can add them together to make sure we get the total cost.

696 + 232 = 928

The expression x^2 + 64 is a quadratic expression that cannot be factored using real numbers. However, it can be factored using complex numbers.

We know that i^2 = -1, so we can write:

x^2 + 64 = x^2 - (-64)

Now, we can use the difference of squares formula, which states that:

a^2 - b^2 = (a + b)(a - b)

Using this formula, we can write:

x^2 + 64 = (x + 8i)(x - 8i)

Therefore, the factored form of x^2 + 64 is (x + 8i)(x - 8i).

[tex]x^{2} + 64[/tex] can be factored into [tex](x + 8i)(x - 8i)[/tex], where [tex]i[/tex] is the imaginary unit.

The percent change is 20%.The correct answer is option C.

To calculate the percent change, we can use the following formula:

Percent Change = (New Value - Old Value) / Old Value * 100

In this case, the old value is $25 (the previous cost to fill the gas tank), and the new value is $30 (the current cost to fill the gas tank).

Percent Change = ($30 - $25) / $25 * 100

Percent Change = $5 / $25 * 100

Percent Change = 0.2 * 100

Percent Change = 20%

Therefore, the percent change is 20%. So the correct answer is C. 20%.

Answer:

a) -4653.
b) -9180.
c) -2700.

Step-by-step explanation:

a) To evaluate using the distributive property, we can break down the multiplication as follows:

-99 x 47 = (-100 + 1) x 47 [Using the fact that -99 can be expressed as -100 + 1]

= (-100 x 47) + (1 x 47) [Distributive property]

= -4700 + 47

= -4653

Therefore, -99 x 47 = -4653.

b) Similarly, we can break down the multiplication using the distributive property:

-85 x 108 = (-100 + 15) x 108 [Using the fact that -85 can be expressed as -100 + 15]

= (-100 x 108) + (15 x 108) [Distributive property]

= -10800 + 1620

= -9180

Therefore, -85 x 108 = -9180.

c) Using the distributive property:

(-54) x 12 + (-38) x 54 = (-54 x 12) + (-38 x 54)

= -648 + (-2052)

= -648 - 2052

= -2700

Therefore, (-54) × 12 + (-38) × 54​ = -2700.

"The correct answer is option A." The missing coordinates of point Q are (a, c/2).We are given the coordinates of points P and N as (0, c) and (2a, 0), respectively. We are also given that point Q lies on the same line as points P, Q, and N. We need to find the missing coordinates of point Q.

Since point Q lies on the same line as P, Q, and N, its x-coordinate must be halfway between the x-coordinates of points P and N. That is, the x-coordinate of Q is:

x-coordinate of Q = (x-coordinate of P + x-coordinate of N) / 2

x-coordinate of Q = (0 + 2a) / 2 = a

So, we know that the x-coordinate of point Q is a.

To find the y-coordinate of point Q, we can use the fact that point Q lies on the same line as point P, which has coordinates (0, c). The equation of the line passing through P and N is:

y - c = (0 - c) / (2a - 0) * (x - 0)

Simplifying this equation gives:

y - c = -c/2a * xy = -c/2a * x + c

Substituting x = a in this equation gives:

y = -c/2a * a + cy = -c/2 + cy = c/2

Hence, n 3 −n=n(n+1)(n−1) is divisible by 6.

Step-by-step explanation:

The condition for any number to be divisible by 6 is that the number must be individually divisible by 3 and 2.

Check whether n 3−n is divisible by 3.

n3−n=n(n+1)(n−1)

When a number is divided by 3 then by the remainder theorem, the remainder obtained is either 0 or 1 or 2.

n=3p or n=3p+1 or n=3p+2, where p is some integer.

If n=3p, then the number is divisible by 3.

If n=3p+1, then n−1=3p+1−1=3p. The number is divisible by 3.

If n=3p+2, then n+1=3p+2+1=3(p+1). The number is divisible by 3.

So, any number in the form of n

3

−n=n(n+1)(n−1) is divisible by 3.

Check whether n

3

−n is divisible by 2.

When a number is divided by 2, the remainder obtained is either 0 or 1 by the remainder theorem.

n=2p or n=2p+1, where p  is some integer.

If n=2p, then the number is divisible by 2.

If n=2p+1 then n−1=2p+1−1=2p. The number is divisible by 2.

So, any number in the form of n

3

−n=n(n+1)(n−1) is divisible by 2.

Since, the given number n

3

−n=n(n+1)(n−1) is divisible by both 3 and 2. Therefore, according to the divisibility rule of 6, the given number is divisible by 6.

Answer:

Step-by-step explanation:

Let's simplify the equation first:

(n-3)(n+2)-(n-3)(n+8)

= n² - n - 6 - (n² + 5n - 24)

= n² - n - 6 - n² - 5n +24

= -6n - 18

Divisible means that the equation can be divided by 6 with no remainder.

If I divide the equation by 6, I get (-n-3)

Mr. Burst needs to eat more than 8 minutes to beat Mr. Bean's record.

Let's define the variables:

x - the number of minutes Mr. Burst has been eating spring rolls

y - the total number of spring rolls Mr. Burst has eaten

Based on the given information, we can set up the following inequality:

y = 8 + 4.5x (equation representing the number of spring rolls Mr. Burst has eaten)

We want Mr. Burst to eat more than 44 spring rolls to beat Mr. Bean's record. Therefore, we can set up the inequality:

y > 44

Substituting the equation for y, we have:

8 + 4.5x > 44

To solve for x, we can isolate the variable:

4.5x > 44 - 8

4.5x > 36

x > 36 / 4.5

x > 8

Mr. Burst needs to eat more than 8 minutes to beat Mr. Bean's record.

The horizontal distance to the base of the object from our current position is approximately 50 meters.

Let's assume that we find out that the height of the object is 50 meters.

Since the object is a right cylindrical cone whose radius equals its height, we know that the angle between PR and QR is 45 degrees (half of 90 degrees).

We can use this information to set up a right triangle with PR as the hypotenuse, PQ as one leg, and QR as the other leg.

We can use trigonometry to solve for PQ, which represents the horizontal distance to the base of the object from our current position.

We know that tan(45) = PQ/50, where PQ is in meters.

Solving for PQ, we get:

PQ = 50 meters x tan(45°) = 50 meters x 1 = 50 meters.
