Basically, the problem is asking us to take 2.20, the length of AB, and work with it through the problem. Well, we are first told that the original polygon is reflected across the x-axis to form the polygon A'B'C'D'E'. This does nothing to the length of AB, so we can move onto the next given section. We are given that A'B'C'D'E' is dilated by a factor of 0.5 (1/2) to form the polygon LMNOP. Here, we will have to take 2.20, the original length, and divide it by 0.5, to get the length of LM. When we perform the operation, we get 1.10, or 1.1. Therefore, the length of LM is 1.10 units. Hope this helped and have a great day!

Answer:

[A] It will take 24 minutes for Joe and Charmaine to meet again at the starting line.

[B] Joe will complete 2 laps

[C] Charmaine will complete 3 laps.

Step-by-step explanation:

Factor two numbers 12 and 8:

12 = 2×2×3

8 = 2×2×2

Find LCM of 12 and 8:

Lcm of 12 and 8 - 2×2×3×2 = 24

Therefore,

[A] How much time does it take for them to meet again at the starting line?

It will take 24 minutes for Joe and Charmaine to meet again at the starting line.

[B] How many laps does Joe complete

Joe will complete 2 laps

[C] How many laps does Charmaine complete?

Charmaine will complete 3 laps.

a prime number 0.5 out of 10: 5 and out of 100:- 50

multipl of 3:- 0/33 out of 10:- 3.3 and out of 100: 33

A negative value of r means that:

tatuchka [14]

Answer:

(d.) Those who score high on one variable tend to score low on the other.

Step-by-step explanation:

A negative value of correlation coefficient (r) shows a relationship between two variables such that as one variable increases, the other decreases. It shows the inverse relationship between two variables with the dependence determined by the value of the correlation coefficient (r).

It can be observed that for graphs with negative slope, the correlation coefficient (r) is similarly negative. This speaks about its relationship too.

The correlation coefficient being negative doesn't mean the relationship between the two variables in question is bad, it just means that the correlation relationship is inverse (still dependent). A perfectly negative correlation is -1.
