Are there options or is it an estimated guess?

64. 87.5% in fractions is 7/8. We divide 56 by 7/8, and get to 64.
56 ÷ 7/8= 56 x 8/7= 448/7, which is reduced into 64.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, 5) and (4, 10). Substitute:

$m=\dfrac{10-5}{4-2}=\dfrac{5}{2}=2.5$

This means that 2.5mm of rain falls every hour

The odds of winning a contest are 3:7. What is the probability winning the contest?

DiKsa [7]

Answer:

0.3

Step-by-step explanation:

Given: The odds of winning a contest are 3:7

To find: probability of winning the contest

Solution:

Probability refers to chances of occurrence of an event.

Odds are defined as (chances for success) : (chances against success)

Probability of winning = (chances for success) : (chances for success + chances against success)

As odds of winning a contest are 3:7,

(chances for success) : (chances against success) = 3:7

So,

Probability of winning the contest = $\frac{3}{3+7} =\frac{3}{10}=0.3$
