ella [17]

Answer:

The number of people who like winter season is 1000.

Step-by-step explanation:

Event event correspond to a set in the Venn diagram, and we use it to find the percentages.

I am going to say that:

Event A: Like summer season

Event B: Like winter season.

55% like summer season

This means that P(A) = 0.55

20% like winter season

This means that P(B) = 0.2

40% don't like both seasons

This means that 100% - 40% = 60% like at least one, which means that P(A \cup B) = 0.6

Proportion who like both:

This is P(A \cap B). The measures are related by the following equation:

P(A \cup B) = P(A) + P(B) - P(A \cap B)

P(A \cap B) = P(A) + P(B) - P(A \cup B)

Using what we have

P(A \cap B) = 0.55 + 0.2 - 0.6 = 0.15

750 like both seasons.

This is 15% of the sample. So the total number of people is t, for which:

0.15t = 750

t = \frac{750}{0.15}

t = 5000

20% like winter season

Out of 5000. So

0.2*5000 = 1000

The number of people who like winter season is 1000.

What will be the price of gas if there is a 27% increase from $2.67 per gallon?​
Rufina [12.5K]

Answer:

The answer is $3.39

Step-by-step explanation:

the question states an increase in price. this means that we need to multiply the current prince ($2.67) by 127%.

drop the percent and put 127 over 100

\frac{127}{100}

multiply

\frac{127}{100} *\frac{2.67}{1}\\\\ \frac{339.09}{100} \\\\3.39

we are dealing with currency so rounding to the hundredths place will suffice.

hope this helps :)
