the qestion is the picture ​

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope / gradient

c is the y intercept

y = 3x + 7

Comparing this equation with the general form above

Gradient of the line = 3

2y - 6x = 8

Divide both sides by 2

We have

y - 3x = 8

To make y the subject move 3x to the right side of the equation

That's

y = 3x + 8

Comparing with the general form above that's y = mx + c

The gradient = 3

y = 3x + 7

A(2 , y ) , B( x , 4)

Since they lie on the line we can substitute their values into the equation to find the missing points

For A(2 ,y)

We have

y = 3(2) + 7

y = 6 + 7

For B( x , 4)

4 = 3x + 7

3x = 4 - 7

3x = - 3

Divide both sides by 3

The circumference of a circle can be obtained using the formulae

If the radius of the circle is given:

If the diameter of the circle is given:

From the first circle given

The radius (r) is given to be = 11.5m

Hence, the circumference of the circle is

Hence, c = 72 meters

For the second circle

We were given the diameter of the circle = 12m

Hence, the circumference of the circle is

Hence, c = 38 meters

For the third circle

The radius of the circle = 24m

Hence, the circumference of the circle is

Hence, c = 151 meters

The probability of choosing all five white balls correctly from a bowl of 69 white balls and the probability of choosing the correct red ball from a bowl of 29 red balls is \({}^{69}C_5/29\) .

The probability of choosing all five white balls correctly can be calculated using the formula for combinations, where the order does not matter and the balls are chosen without replacement. The probability is given by:

P(Choosing all 5 white balls correctly) = (Number of ways to choose 5 white balls correctly) / (Total number of possible combinations)

The number of ways to choose 5 white balls correctly is 1, as there is only one correct combination.

The total number of possible combinations can be calculated using the formula for combinations, where we choose 5 balls out of 69. It is given by:

Total number of combinations = \({}^{69}C_5\)

Next, we need to calculate the probability of choosing the correct red ball from a bowl of 29 red balls. Since there is only one correct red ball, the probability is 1/29.

Finally, to find the likelihood of being the winner of the Powerball lottery, we multiply the probability of choosing all five white balls correctly by the probability of choosing the correct red ball:

Likelihood = P(Choosing all 5 white balls correctly) * P(Choosing correct red ball)

=\({}^{69}C_5 \times 1/29\\\)

This gives us the probability of being the winner of the Powerball lottery.

Therefore,  the dimensions that minimize the cost to build the fence around the fencing are 20 m by 10 m.

To minimize the cost of fencing a rectangular field of 200 m2, we need to find the dimensions with the least total cost. Let's use the variables x and y for the length and width of the field, respectively. The area of the field is A = xy = 200 m2.
First, we'll find an equation relating x and y using the area: y = 200/x.
Next, we'll find the cost equation: Cost = 3x + 3x + 8y + 8y = 6x + 16y.
Now, substitute y in the cost equation: Cost = 6x + 16(200/x).
To minimize the cost, we'll find the derivative of the cost function with respect to x and set it equal to zero:
d(Cost)/dx = 6 - 3200/x^2 = 0.
Solving for x, we get x = 20 m. Then, using y = 200/x, we find y = 10 m.
Therefore,  the dimensions that minimize the cost to build the fence around the fencing are 20 m by 10 m.

The probability that the sample mean is greater than 168 is approximately 0.0655, or 6.6% (rounded to the nearest tenth of a percent).

To find the probability that the sample mean is greater than 168, we can use the central limit theorem and the properties of the normal distribution.

The central limit theorem states that for a large enough sample size (in this case, n = 50), the distribution of sample means will approach a normal distribution, regardless of the shape of the population distribution.

Given that the population mean is 164 and the population standard deviation is 18.65, we can calculate the standard deviation of the sample mean, also known as the standard error, using the formula:

Standard Error (SE) = Population Standard Deviation / √(Sample Size)

SE = 18.65 / √50

SE ≈ 2.636

Next, we need to standardize the value of 168 using the sample mean and the standard error. This allows us to calculate the probability using the standard normal distribution.

Z = (Sample Mean - Population Mean) / Standard Error

Z = (168 - 164) / 2.636

Z ≈ 1.516

To find the probability that the sample mean is greater than 168, we can look up the corresponding area under the standard normal curve to the right of Z = 1.516. This can be done using a standard normal distribution table or a statistical calculator.

Using a standard normal distribution table, we find that the area to the right of Z = 1.516 is approximately 0.0655.

Therefore, the probability that the sample mean is greater than 168 is approximately 0.0655, or 6.6% (rounded to the nearest tenth of a percent).

The result of each trigonometric functions are:

a) sin X = 7√149 / 149

b) sin Z = 10√149 / 149

c) cos X = 10√149 / 149

d) cos Z = 7√149 / 149

In a right triangle, the sine of an angle is equal to the length of the side opposite the angle divided by the length of the hypotenuse, and the cosine of an angle is equal to the length of the adjacent side divided by the length of the hypotenuse. Using this trigonometric functions, we can calculate sin X, sin Z, cos X, and cos Z as follows

sin X = YZ / XZ = 7 / √149

cos X = XY / XZ = 10 / √149

sin Z = XY / XZ = 10 / √149

cos Z = YZ / XZ = 7 / √149

To simplify these fractions, we can rationalize the denominator by multiplying the numerator and denominator by √149:

sin X = 7√149 / 149

cos X = 10√149 / 149

sin Z = 10√149 / 149

Answer: Even functions

Symmetric about the yy-axis

When you plug -x−x into the function, it will simplify to be the same as the original function. This means that it doesn’t matter whether you plug in xx or -x−x, your output will be the same. So

f(-x)=f(x)f(−x)=f(x)

Below are graphs that are even and symmetric about the yy-axis.

even functions are symmetric about the y-axis

Odd functions

Symmetric about the origin

When you plug -x−x into the function, it will simplify to be negative of the original function, or the original function multiplied by -1−1. This means that when you plug -x−x into the function, you’ll get the same output as you do when you plug in xx, except it will be negative (or have the opposite sign as the original output). So

f(-x)=-f(x)f(−x)=−f(x)

Below are graphs that are odd and symmetric about the origin. Be sure to visually compare quadrants that are diagonal from each other (quadrants 1 and 3, and quadrants 2 and 4).

odd functions are symmetric about the origin

Neither even nor odd

Not symmetric about the yy-axis, and not symmetric about the origin

The function has no symmetry. It’s possible that a graph could be symmetric to the xx-axis, but then it wouldn’t pass the Vertical Line Test and therefore wouldn’t be a function.

1. area of a circle = π\(r^{2}\)

2. to find the area of a circle inside a square is the same thing. but if you're trying to find the area of a square WITH a circle inside, you just subtract the area of the circle from the square.

EX: If you have a square that has an area of 24cm and then you have a circle that has an area of 16 cm. To find the area of the square, you just subtract 16 from 25, which would look like 24 - 16 = x

To show that any sequence of row operations that reduces B to also reduces A to C, the following pieces of information in the problem statement are relevant:

A. The zero matrix may be factored as 0= B * 0. This is not relevant for showing that any sequence of row operations that reduces B to also reduces A to C.B. A=B.

This is not relevant for showing that any sequence of row operations that reduces B to also reduces A to C.C. B is invertible. This is relevant for showing that any sequence of row operations that reduces B to also reduces A to C.D. The converse not true. This is relevant for showing that any sequence of row operations that reduces B to also reduces A to C.

Given the relevant pieces of information from the previous step, there exist elementary matrices E1, ..., Ep  corresponding to row operations that reduce B to I, in the sense that Ep...E2E1B=I. Applying the same sequence of row operations to A amounts to left-multiplying by the product E1E2...Ep.

Therefore, A is transformed to C, since

The inequality that can be used to find the number of gigabytes used is 52.50+5g<75 and the value of g should be less than 4.5.

According to the question,

We have the following information:

Gabriel pays a flat cost of $52.50 per month and $5 per gigabyte. He wants to keep his bill under $75.

Now, the number of gigabytes used are represented by g.

So, we will have the following inequality:

52.50+5g<75

Now, we will solve this inequality.

Subtracting 52.50 from both the side:

5g<75-52.50

5g<22.5

Dividing by 5 on both the sides:

g<22.5/5

g<4.5

Hence, the inequality that can be used to find the number of gigabytes used is 52.50+5g<75 and the value of g should be less than 4.5.
