James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply. 7 x + 4 and 3 x + 5 + 4 x minus 1 When x = 2, both expressions have a value of 18. The expressions are only equivalent for x = 4 and x = 6. The expressions are only equivalent when evaluated with even values. The expressions have equivalent values for any value of x. The expressions should have been evaluated with one odd value and one even value. When x = 0, the first expression has a value of 4 and the second expression has a value of 5. The expressions have equivalent values if x = 8.

Step-by-step explanation:

Mr. Jones sold two pipes at $1.20 each. Based on the cost, his profit was 20% and his loss on the other was 20%. On the sale of the pipes, he:

(a) broke even, (b) lost 4 cents, (c) gained 4 cents, (d) lost 10 cents, (e) gained 10 cents

Answers

Answer:

Selling price of the first pipe = $1.20

Profit = 20%

Let’s try to find the cost price of the first pipe

CP = Selling price - Profit

CP = 1.20 - 20% of CP

CP = 1.20 - 0.20CP

CP + 0.20CP = 1.20

1.20CP = 1.20

CP = 1.201.20

CP = $ 1

Selling price of the Second pipe = $1.20

Loss = 20%

Let’s try to find the cost price of the second pipe

CP = Selling price + Loss

CP = 1.20 + 20% of CP

CP = 1.20 + 0.20CP

CP - 0.20CP = 1.20

0.80CP = 1.20

CP = 1.200.80

CP = $1.50

Therefore, total cost price of the two pipes = $1.00 + $1.50 = $2.50

And total selling price of the two pipes = $1.20 + $1.20 = $2.40

Loss = $2.50 – $2.40 = $0.10

Therefore, Mr. Jones loss 10 cents.

If the mean absolute deviation is close to 0, then what does that mean about the data set

Answers

The datum would be around, or, the same value; likewise, when graphed, each datum would be closer to the equation’s line.

The average difference is very less of all the elements in a data set than the mean of the same data set.

What is the mean absolute deviation?

It is defined as the measure to show the variation in data set in other words between the mean and every data value the distance is known as the MAD.

As we know the mean absolute deviation is the average distance between each data point and the mean.

The mean (average) difference between each data value and the data set's mean is known as the mean absolute deviation. It can be used to quantify the data set's dispersion as well as to solve statistical issues in the actual world.

If the mean absolute deviation is close to 0 it means the average difference is very less of all the elements in a data set from the mean of the same data set

Thus, the average difference is very less of all the elements in a data set than the mean of the same data set.

Answers

Answer:

Y=74, x=106.

Step-by-step explanation:

First, if you will notice, that 16+Y=90. Why? Because there is a square instead of a semicircle at the angle, which means that 16+Y=90. 90-16=74, so Y is 74. Then, we see that 90 plus an unknown angle equals x. But, using a rule of geometry, we know that the unknown angle is 16. So, x=90+16, and since 90+16 is 106, we get Y=74, X=106.

Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related. Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature).
