Answer:
The age distribution of a population is shown.
a. The probability that a person chosen at random is at least 15 years old is <em><u>1</u></em><em><u>4</u></em><em><u>%</u></em>
b. The probability that a person chosen at random is 25 - 44 years old is <em><u>26%</u></em>
Answer:
12
Step-by-step explanation:
Assume that those angles' curve in the triangle have same measure.
Law of Sin states that:
From the question, assume that B and C are congruent or have same measure. Let B and C be congruent; angle B = angle C thus:-
Let b = x and c = 12; for angle B, it's not given so leave it.
Multiply both sides by LCM which is 12x.
Divide both sides by sinB.
Therefore, x = 12.
Is this the question of when will they have to buy all 3 items again
h = 9.2 cm
Solution:
Base of smaller triangle = 5 cm
Height of smaller triangle = 2.3 cm
Base of larger triangle = 15 cm + 5 cm = 20 cm
Height of larger triangle = h
Multiply by 20 on both sides.
9.2 = h
So that Ryan should have add 15 and 5 to get a denominator of 20 on the right sides of the first line. Doing so gives the correct value, h = 9.2 cm.
