Just curious, I want to see who can get this. tooooootttalllllly know it already

Assume that we have two variables a and b, and that: a = b

Multiply both sides by a to get: a2 = ab

Subtract b2 from both sides to get: a2 - b2 = ab - b2

This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b). If you're not sure how FOIL or factoring works, don't worry—you can check that this all works by multiplying everything out to see that it matches. The end result is that our equation has become: (a + b)(a - b) = b(a - b)

Since (a - b) appears on both sides, we can cancel it to get: a + b = b



Since a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = b

Combining the two terms on the left gives us: 2b = b

Since b appears on both sides, we can divide through by b to get: 2 = 1

If Sheila rotates triangle PQR 90° counterclockwise to form triangle LMN, what is the measure of angle MNL?
A.130 °
B.100 °
C.50 °
D.30 °

Answers

Answer:

30

Step-by-step explanation:

This is a bit nasty, but you must keep the order in mind. PQR means that Q is the middle letter. M is also the middle letter. That's the easy part. What does MNL mean?

The lettering goes clockwise. MNL is the same thing as QRP. So what is R?

50 + 100 + R = 180

150 + R = 180

R = 180 - 150

R = 30

NO TROLL COMMENTS OR IF U DONT KNOW THE ANSWER, DONT ANSWER

Answers

Answer:

a) 0.3125

b) 45

Step-by-step explanation:

Remark

5 students own a smart phone

11 do not.

Part A

The probability of owning a smart phone is 5/16. Where did the 16 come from.? You must use a total for the sample. You can't choose someone without a smart phone and figure out the probability of doing that if you use 11  in the denominator.

So the answer is 5/16 = 0.3125

Part B

You have to set up a proportion for this.

x / 144 = 5/16  

Notice where the 144 goes. It is across from 16. Both of them represent the total number of students. Multiply both sides by 144

x * 144 / 144 = 5 * 144/16

x = 720 / 16

x = 45

A six-sided number cube labeled 1 through 6 is rolled 600 times. An odd number is rolled 272 times. Compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number and select one of the statements below that best describes the situation. (5 points)

a
The experimental probability and relative frequency are the same.

b
The experimental probability is larger than the relative frequency.

c
The experiment probability is smaller than the relative frequency.

d
There is not enough information to determine the relative frequency.

Answers

Answer:

Relative frequency is defined as the number of "desired" results divided by the total number of possible results. Experimental probability is defined the same way. This means that the first choice is best, the experimental probability and relative frequency are the same.

The theoretical probability, on the other hand, would be 0.5, or 300/600, which is larger than the experimental probability.
