Find two consecutive even integers whose sum is 22

andrew11 [14]

10 & 12

x = 1st consecutive even number

x + 2 = 2nd consecutive even number

x + x + 2 = 22

2x + 2 = 22

a six sided number cube has faces with the numbers 1 through 6 marked on them. what is the probability that a number less than 2

iris [78.8K]

Solution:

we are given that

A six sided number cube has faces with the numbers 1 through 6 marked on them.

we have been asked to find the probability that a number less than 2 will occur on one toss of the number cube.

Since a number less than 2 is only one and that is "1" and total number of possible outcome is 6.

and as we know that probability is given using the formula

$P(E)= \frac{n(E)}{n(S)}\\ \\$

Substitute the values we get

$P(E)= \frac{1}{6}$

Hence the required probability is 1/6.

Effectus [21]

Answer:

The correct option is;

(B) Yes, because sampling distributions of population proportions are modeled with a normal model.

Step-by-step explanation:

Here we have the condition for normality being that where we have a population with a given mean and standard deviation, while a sufficiently large sample is drawn from the population while being replaced, the distribution of the sample mean p will be distributed normally according to central limit theorem.
