At a stop sign, some drivers come to a full stop, some come to a rolling stop' (not a full stop, but slow down), and some do not
Natasha2012 [34]

Answer:

Option C.

Step-by-step explanation:

Given information:

Male-Full stop = 6, Male-Rolling stop = 16, Male-No stop = 4

Female-Full stop = 6, Female-Rolling stop = 15, Female-No stop = 3

Using the given information we get

Total number of males = 6 + 16 + 4 = 26

Total number of males = 6 + 15 + 3 = 24

Probability of No stop is

p=\dfrac{\text{No-stop}}{Total}

p=\dfrac{4+3}{50}

p=\dfrac{7}{50}

We need to find the number of males that would we expect to not stop at all.

Expected number of males = Number of males × Probability

Expected number of males = 26\times \dfrac{7}{50}

Expected number of males = 3.64

Therefore, the correct option is C.

Mira has breakfast at a restaurant. She leaves a 20% tip of $1.80
Sedaia [141]
Let x be the price of the breakfast.

We know that 20 percent of x is 1.80

Let's write this as a mathematical equation

0.2 x = 1.8

Let's divide both sides by 0.2 to isolate the x

x = 1.8 / 0.2

= 9

The price of the breakfast was $9.

Have an awesome day! :)

? Write 126 as a product of primes. Use index notation when giving your answer.​
Talja [164]

Answer:

2 x 7 x 3²

Step-by-step explanation:

When finding primes, you use the method I attatched as a picture. Start with the large number at the top, slowly dividing it by factors of it.

The picture shows that the primes 126 is a product of is:

2, 7, 3, 3

Or:

2 x 7 x 3 x 3

This can be simplified into:

2 x 7 x 3²

Hope this helps!
