Explanation:
To determine how many guests are still there, simply subtract 37 from 75:
The second bus carried 38 passengers (75 - 37).
Explanation:
Let's start by calculating the reported proportion of individuals with blonde hair in the first sample (2,048*0.375 = 768): The real number of people with blonde hair, however, was 162.5% higher than the reported figure (768*1.625 = 1,248).
Let's now compute the reported proportion of individuals in the second sample who have green eyes: 312*0.875 = 273. The real number of people with green eyes was, however, just 33.33% of the claimed figure (273*0.3333 = 91).
Therefore, 1,248 - 91 = 1,157 is the difference between the number of persons with blonde hair in the first sample and the number of people with green eyes in the second sample.
Explanation:
There is a different rule for the numerators and denominators in this series. Each denominator rises by one and each numerator falls by one. This means that in the final term of the series (2/7), -1 should be deducted from the numerator (2) and +1 should be added to the denominator (7). The outcome is 1/8.
Explanation:
11 - 27 - 7 = 11
Explanation:
First, calculate one side:
57 - 12 = 45
So the equation becomes:
45 = 33 + ?
Now isolate the unknown:
45 - 33 = ?
Now calculate:
45 - 12 = 12
Explanation:
Find out the price of one bottle first:
60/42 = 1.43
To get the price of five bottles, multiply by 5:
1.43 x 5 = $7.15
