A number cube is rolled 450 times. The number 3 comes up 67 times. What is the theoretical probability of rolling a three,

1 answer:

6 0

The answer to this is 67 / 450

We know that:
Experimental probability = number of positive results / number of experiments

So the Experimental probability = 67 / 450

Researchers wanted to see which species of lizard (A, B, or C) is most likely to survive a bacterial infection. So they infected

Slav-nsk [51]

Answer:

A) attached below

B) 0.61

C) 0.47

Step-by-step explanation:

Given data:

Total number of lizards infected = 38

Of the 15 species B lizards 40% survived

For specie C one more survived than died

Out of the 24 lizards that died 1/3 were species A

A) contingency table

attached below

B) Determine the proportion of these lizards in this study that were either specie A or Specie B

P ( A or B ) = ( 8 + 15 ) / 38 = 0.605 ≈ 0.61

C) determine the probability that specie C lizard did not study

P ( not surviving | C ) = 7 / 15 = 0.466 ≈ 0.47

She spent 1/6 of it on snacks and 1/3 of it on a new book. She saves the rest. What fraction of the money did she save?

Doss [256]

Answer:

Step-by-step explanation:

First step is that you need to have the same denominators so 1/3=2/6

If she spent 1/6 on snacks and 2/6 on a book which means she spent 3/6

so the fraction of what she saved is 3/6 or 1/2

14.4% of what number is 10.4

Helga [31]

First, convert "of" to x and put this info into an equation:

Let n represent the unknown number.

14.4 % x n= 10.4
n = 10.4 / 14.4%
n = 72.22222
n = ~72

Hope this helps!
