The measure of angle AFB = 78°

Answers

Answer: is C

Step-by-step explanation: you have a 90 so 90-78 is 12

The answer is 12

We know that angles AFB and CFD and BFC sum up to 180

Using this information we can write the equation

AFB + CFD +BFC = 180

Now substitute known values:

78 + 90 (it is a right angle) + BFC = 180

Now solve-
You should get

180-168 which is 12

Vertex 0,-1 and axis of symmetry is x=0

Answer: See explanation

Step-by-step explanation:

Vertex is the point where two lines meet.

The vertex of the function is (0, -1)

The axis of symmetry is a line that divides the function into two symmetrical lines.

The axis of symmetry is x = 0 since that's the line that meets with the vertex and it makes the lines symmetrical.

Question 3 options: 10% 15% 20% 25%

Answers

Answer: 10%

Step-by-step explanation:

The probability of selecting exactly 2 right-handed people are approximately 20% of the time.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

The results of the simulation are shown.

RRR RLR RRR RRL RRR RRR RRR RRR RRR LRR RRR RRR RRR RRR RRR RRR RLR LRL RRR RRL RRR RRR LLR RRR RRR RRR LRR RRR RRR RRR

Here, probability = 6/30

= 1/5

= 0.2

= 0.2×100

= 20%

Therefore, probability of selecting exactly 2 right-handed people are approximately 20% of the time.
