Lets discern the infomation:
number_men = 165*0.6 = 99
so there are 99 men
non_fiction = 165 * 0.4 = 66
so 66 authors write non-fiction.
men writing non-fiction are 40, so 59 men write fiction, and 26 women write non-fiction.
probability of author non-fiction or man?
non-fiction: 40 men + 26 women = 66 total
man writers = 99
so in total 99 man + 26 women = 115 authors
hence the probability is:
115/165 = 69.6%
Answer:
A: 7
B: 8
C: 6
Step-by-step explanation:
You have to try to find the the same greatest factor of both of the numbers.
Since both of the numbers are divisible by 7 the number of groups equals 7.
So you divide the number of girls, which is 56, by 7, the number of girls in each group is 8.
Then you divide the number of boys, which is 42, by 7, the number of boys in each group is 6.
70/100 just multiply them both by 10
Answer:
1.30$
Step-by-step:
Since they sell their cookies for 1/3 of the price for the last 15 minutes, cookies go on sale at 8:45.
Laura bought them at 8:30, and did not get a discount.
She bought 3 cookies for 65 cents each. That's 3 x 65 = 195 cents.
Had she waited 15 minutes, she would have gotten a discount of 1/3 off.
195 cents x (1/3) is 65.
195 - 65 = 130 cents.
130 cents or 1 dollar 30 cents.
One third (or 1/3 ) is the correct answer
