Two different floor plans are being offered in a new housing development. Several prospective buyers from three different age gr
zepelin [54]

Answer:

0.677

Step-by-step explanation:Add up the values in the plan A column. There are 10+12+16 = 38 people who prefer plan A.

Add up the values in the "40-49" row to find that 16+8 = 24 people are ages 40 to 49.

We have 38+24-16 = 46 people who either prefer plan A, are aged 40-49, or fit both descriptions. I subtracted off 16 because those 16 people were counted twice when adding 38 and 24.

An alternative way to get this value of 46 is to add up everything that is in column1 or row 3 (or both). So that would get 10+12+16+8 = 46.

Now add up everything in the table to find out how many people were surveyed total. That would be 10+7+12+15+16+8 = 68 people overall.

The probability of someone liking plan A, or being age 40-49, or both is 46/68 = 0.6765 approximately. Rounding to 3 decimal places gives 0.677

Last week Macy ran 4 times as many miles as Jackson. They ran a total of 20 miles. How many miles did Macy run? how many morr mi
WITCHER [35]
Macy 5 miles because she ran 4 times more than Jackson in relation to Jackson ran 5 mile, this problem can oftenly be seen as
j = 20 \div 4
which would end up in the answer being 5 which is the right answer while someone else can see it as
j = 20 - 4
which would equal 16 which is incorrect because the problem didn't say that Jackson ran one mile nor 4 miles which would be 4*4 or 16 when the correct answer is 20/4=5 because 4*5=20
