If the probability of surviving in a head on car accident is 0.012 at 55 mph. Then what is the probability of not surviving?

The probability is just a fraction of the success over the total number of experiments. The opposite would be the number of fails over the total number of experiments. When you add probabilit of the successes and the fails, they equal to 1.

So, the probability of not surviving would be 1-0.012 = 0.988

The answer is 0.988.

A spinner has 12 equal sections:5 red 4 green and the rest are black. In 921 spins how many times can you expect to spin black?

Komok [63]

Answer:

230

Step-by-step explanation:

12 sections total

5 red, 4 green, the rest black

12-5-4 = 3 sections are black

3/12 = 1/4 of the sections are black

1/4 represents the probability of landing on black for one spin

(1/4)*921 = 230.25 which rounds to 230

We expect to land on a black section about 230 times out of 921 times total.

What is the distance between the longest dog in the shortest dog Short 7 over 8 longest 3 over 8 what is the difference

Step2247 [10]

Answer:

The distance between the longest dog and the shortest dog is 4 over 8 ( $\frac{4}{8}$ ) OR 1 over 2 ( $\frac{1}{2}$ )

Step-by-step explanation:

From the question,

Short is 7 over 8, that is,

Short = $\frac{7}{8}$

and longest is 3 over 8, that is

Longest = $\frac{3}{8}$

The distance between the longest dog and the shortest dog can be determined by finding the difference between the fractions. That is,

$\frac{7}{8} - \frac{3}{8} = \frac{7 - 3}{8}$

$= \frac{4}{8}$

$= \frac{1}{2}$

Hence, the distance between the longest dog and the shortest dog is 4 over 8 ( $\frac{4}{8}$ ) OR 1 over 2 ( $\frac{1}{2}$ ).

Is 2x-4x = -7x+10 a no solution? infinite solution? or one solution?

nikitadnepr [17]

Answer:

One solution, x = 4.

Step-by-step explanation:

2x-4x = -7x+10

-2x = -7x + 10

7x - 2x = 10

5x = 10

x = 2.
