Yes but it would result in a decimal.
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
Answer:14%
Step-by-step explanation:
final grade score=a
20% of a=15
20/100 x a=15
20a/100=15
Cross multiply
20a=15 x 100
20a=1500
Divide both sides by 20
20a/20=1500/20
a=75
B% of 75=10.5
B/100 x 75=10.5
75B/100=10.5
Cross multiply
75B=10.5 x 100
75B=1050
Divide both sides by 75
75B/75=1050/75
B=14
Step-by-step explanation:
Result:
1.5 - 1 1/5 = 3/10 = 0.3
Spelled result in words is three tenths.
How do you solve fractions step by step?
Conversion a decimal number to a fraction: 1.5 = 15/10 = 3/2
a) Write down the decimal 1.5 divided by 1: 1.5 = 1.5/1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
1.5/1 = 15/10
Note: 15/10 is called a decimal fraction.
c) Simplify and reduce the fraction
15/10 = 3 * 5/2 * 5 = 3 * 5/2 * 5 = 3/2
Conversion a mixed number 11/5 to a improper fraction: 1 1/5 = 1 1/5 = 1 · 5 + 1/5 = 5 + 1/5= 6/5
Sure.
The common difference is 1/3
d = 8/15 - 1/5 = 8/15 - 3/15 = 5/15 = 1/3
d = 13/15 - 8/15 = 5/15 = 1/3
So the seventh term is
S_n = S_1 + (n-1)d
S_7 = (1/5) + 6(1/3) = 11/5
The sum is the average of the first and last times the number of elements
(1/2)(1/5 + 11/5)(7) = 7(6/5) = 42/5 = 8.4
Answer: 42/5
