Answer:

answer: C. 5 out of 10

Step-by-step explanation:

Theoretical probability is what is expected to happen sense a coin has 2 sides theres a 1/2 chance at getting heads so 5 out of 10 is the theoretical probability because 5 is half of 10 hope this helps!

What is the slope of the line that goes through (0,0) (5,1)

GalinKa [24]

Hey there!

In order to solve this problem, we can use the slope given two points formula:

y2-y1/x2-x1

Now, we can plug in our points to get:

1-0/5-0 = 1/5

Your answer is 1/5, or B.

Hope this helps!

1. According to a recent survey, 13 out of the 33 students in a class take the bus to school. What is the ratio of students who

AlexFokin [52]

Answer: (1) 13/20 (2) 8 (3) Yes. They are proportional

<u>Step-by-step explanation:</u>

(1) 13 students take the bus.

33 - 13 = 20 students do not take the bus

$\dfrac{\text{take the bus}}{\text{do not take the bus}}:\dfrac{13}{20}$

(2)

$\dfrac{2\ red}{3\ green}=\dfrac{x}{12\ green}\\\\\\\underline{\text{cross multiply}:}\\2(12)=3(x)\\24=3x\\8=x$

(3)

$\dfrac{6}{10}\div \dfrac{2}{2}\quad =\dfrac{3}{5}\\\\\\\dfrac{9}{15}\div \dfrac{3}{3}\quad =\dfrac{3}{5}\\\\\\\dfrac{15}{25}\div \dfrac{5}{5}\quad =\dfrac{3}{5}$

All of the fractions simplify to the same number so they ARE proportional.
