Martina read that approximately 10% of all people are left-handed. She wants to design a simulation to approximate the probability of selecting exactly 2 right-handed people when 3 people are randomly selected.

Martina spins the arrow on the spinner 3 times and records the resulting letters. Martina performs the simulation 30 times. 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
Based on the results of this simulation, when 3 people are randomly selected, exactly 2 right-handed people are selected approximately _______ of the time. Question 3 options:

10%


15%


20%


25%

Answers

To approximate the probability of selecting exactly 2 right-handed people when 3 people are randomly selected, we need to look at the simulation results and count the number of times exactly 2 right-handed people were selected.

From the simulation results, we can see that there are 6 instances where exactly 2 right-handed people were selected:

RLR

RRL

LRR

LLR

RRL

LRR

Out of the 30 simulations, this means that 6/30 or 1/5 or 20% of the time, exactly 2 right-handed people were selected when 3 people are randomly selected.

Therefore, the answer is 20%.

Olivia is shopping at macys . The cost of all the items at the store include tax. Olivia buys some scarves that cost $5 each and 2 purses that cost $12 each. The cost of Olivia's total purchase is $39. Which equation can be used to find s, the number of scarves that Olivia buys?
1. 5 + 24s=39
2. 5s + 24=39
3. (24 + 5)s=39
4. 24 t × 5 + s=39

Answers

Answer:

2, 5s + 24 = 39

Step-by-step explanation:

Using simple math, we can figure out that the purses cost $24 total. That leaves $15 for the scarves. 15/5 = 3, therefore, 3 scarves were purchased. Using the equation 5s + 24 = 39, we can sub s for 3, making it 5(3) + 24 = 39. The math checks out.

it would be number 2!

Wow! This is hard. I will try i answer it but for now other people will have ze chance

Step-by-step explanation:

A, B, C, and E are correct.

12 x 1.5 = 18 (actual length)
8 x 1.5 = 12 (actual width)

So perimeter = 18 + 18 + 12 + 12= 60
Area = 18 x 12 = 216
