Answer:
t represents the number of miles per hours it takes ride your bicycle.
Step-by-step explanation:
9t = 26
you divide 26 by 9 because you are moving it over the equal sign.
t = 2 reminder 8 or; 2 8/9
The answer is D.
Factor the equation (what factors of -72 add up to 34)
(x + 36)(x - 2) = 0
x = -36, x = 2
Answer: what
Step-by-step explanation:
Absolute value is always positive, so <span> |-3| equals positive 3</span>
Using the binomial distribution, it is found that there is a 0.5 = 50% probability of selecting a two-child family with one boy and one girl.
For each child, there are only two possible outcomes, either it is a boy, or it is a girl. The probability of a child being a boy or being a girl is independent of any other child, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- Two children, hence
. - Equally as likely to be a boy or a girl, hence
.
The probability of one of each is P(X = 1), hence:


0.5 = 50% probability of selecting a two-child family with one boy and one girl.
