Emigration. in 2007, 51% of all emigrants to canada were males, 82% were at least 18 years old, and 42% were male of at least 18 years of age. find the probability that a randomly selected person who emigrated canada in 2007 was: a) male and under 18 years old. b) either male or at least 18 years of age. c) female and under 18 years old.

It can help to make a table from the given information. The attached table is filled in from the given values (underlined in green). We know that rows and columns must add to 100%, so the remaining numbers are easily found by subtraction.

a) This is the number in the upper left corner, 9%.

b) This is the sum of the over 18 row (82%) and the number in (a), so is ...

... 82% +9% = 91%.

Alternatively, it is the sum of the male column (51%) and the over 18 female number (40%):

... 51% +40% = 91%.

It is also the complement of the number in (c).

c) This is the number in the upper center box, 9%.

It is also the complement of the number in (b).

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
