Answer:

1. $266\dfrac{2}{3}\%$

2. $400\%$

Step-by-step explanation:

1. Fraction $\frac{1}{4}$ is 100%, then

$\dfrac{1}{4} - 100\%\\ \\\dfrac{2}{3} - x\%$

Write a proportion:

$\dfrac{\frac{1}{4}}{\frac{2}{3}}=\dfrac{100}{x}$

Cross multiply:

$\dfrac{1}{4}x=\dfrac{2}{3}\cdot 100\\ \\x=4\cdot \dfrac{2}{3}\cdot 100\\ \\x=\dfrac{800}{3}\\ \\x=266\dfrac{2}{3}\%$

2. Fraction $\frac{1}{6}$ is 100%, then

$\dfrac{1}{6} - 100\%\\ \\\dfrac{2}{3} - x\%$

Write a proportion:

$\dfrac{\frac{1}{6}}{\frac{2}{3}}=\dfrac{100}{x}$

Cross multiply:

$\dfrac{1}{6}x=\dfrac{2}{3}\cdot 100\\ \\x=6\cdot \dfrac{2}{3}\cdot 100\\ \\x=\dfrac{1,200}{3}\\ \\x=400\%$

A number is picked randomly in the range [2,8]. If past selection indicates that the numbers picked are less than 5, what is the

yawa3891 [41]

Answer:

a) P = 2/7

b) P = 4/7

c) P = 1/7

Step-by-step explanation:

In the range of [2,8], we have the following integers which are: 2, 3, 4, 5, 6, 7, 8. So this is a total of 7 integers.

a) We look for the probability that the numbers are less than 4, so we conclude that there are possible numbers 2 and 3 out of possible 7, so the required probability is equal to P = 2/7.

b) We look for the probability that the numbers are greater than 4, so we conclude that there are possible numbers 5, 6, 7, 8 out of possible 7, so the required probability is equal to P = 4/7.

c) Based on the previous two examples, we conclude that the required probability is P = 2/7· 1/2=1/7.
