The problem is to find how many students have either blond hair or glasses and then divide that by the total number of students; that will find the probability.
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.
Z=1 eventually you get 15 divided by 15 giving you Z=1 it’s a long equation
Step-by-step explanation:
9v-4v+7v
= 5v+7v
= 12v
The answer is 12v
Hey there!
I'm thinking B because it just makes the most sense reading it aloud. Quick tip though when there's a question like this just read the paragraph or sentences with all the possibilities in the blanks and you can kind of just tell which one it is by the way it sounds, you know?
Hope I helped, lemme know if I'm correct please! Have a spectacular day!
Answer:
each side is 55.125cm
Step-by-step explanation:
you have to divide the area by 2
then do 441/2=220.5
then divide this by 4 because a square has 4 equal sides so 220.5/4=55.125
