If an individual is selected at random, what is the probability that he or she has a birthday in July? Ignore leap years.
Answers
The probability is [tex]\frac{31}{365}[/tex] , If an individual is selected at random have birthday in July .
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]
According to the question
Total number of days in year = 365
Total number of days in a leap year = 366
As, given Ignore leap years
So, we will take days of years as 365 .
Now,
he or she has a birthday in July
i.e ,
It can be be happen any day of July
Total days in July = 31
Now,
Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]
substituting the value
Probability(Event) = [tex]\frac{Total\\\ day\\\ in\\\ July }{Total\\\ days\\\ in\\\ year}[/tex]
Probability(Event) = [tex]\frac{31}{365}[/tex]
Hence, If an individual is selected at random the probability have birthday in July is [tex]\frac{31}{365}[/tex] .

Answers
Answer:
a. When you have two parallel lines cut by a transversal, angles 4 and 6 become same side interior angles, meaning they add to 180 degrees. Alex's mistake is that he thought angles 4 and 6 were corresponding angles, which are equal to each other (corresponding angles would be like angles 2 and 6. they are in the same place in relation to the transversal and the parallel lines. if you moved line l down, angle 2 would be on the same spot as angle 6, so they are corresponding angles).
b. angles 4 = 140 degrees
Step-by-step explanation:
a. Alex thought that angles 6 and 4 were corresponding angles, however, they are same side interior angles. Because two parallel lines are cut by a transversal, we can conclude that angles 4 and 6 are same side interior angles.
Same side interior angles are angles that add to 180, so you would do 180-40 to get angle 4. the measure of angle 4 would be 140 degrees (the answer to b).
Pat started reading at 1pm . He reads five pages in 15 minutes. If Pat reads until 2:45 pm, how many pages has he read?
Answers
Answer:
35 pages
Step-by-step explanation:
First count how many minutes have passed. Divide by 15, then multiply by 5 since 5 pages are read every 15 minutes.
Answer:
35 pages
Step-by-step explanation:
If Pat reads 5 pages in 15 minutes, then it means that for every 5 pages he reads, it will take him 15 minutes. So, his rate is 5/15, simplified to 1/3. For every 1 page he reads, it will take him 3 minutes. 1pm-2:45pm is 1 hour and 45 minutes, which is 105 minutes. Now we just have to divide it by 3, since he reads 1 page every 3 minutes. 105/3=35. He will read 35 pages.

kkkkkk kkkkkk kkkWhy were the Punic War so important for the development of the Roman Empire?
Answer:
20
Step-by-step explanation:
If you have 60,000,000 barrels of crude oil and 34% of the barrels are gasoline then you have to set up the problem like this because you have to find out how much 34% of 60,000,000 is first in order to solve the problem.
is/of x 100/%
60,000,000 / a X 100 / 34
so..60,000,000 x 34 = 2,040,000,000
then divide that amount by 100= 2,040,000,000 / 100 = 20, 400,000
so the 34% actually is the total 20,400,000. Now, you divide the dollar amount 408,000,000 million barrels by the total amount of gasoline which is 20,400,000.
408,000,000 / 20,400,000 = 20
So each barrel of gasoline cost $20.

Answers

Step-by-step explanation:
10 - 30 is not possible they owe
The value of price elasticity of demand is -4.
The price elasticity of demand refers to how a particular good responds as a result of a change in the price. In this case, the price elasticity of demand is calculated as:
= Percentage change in quantity/ Percentage change in price.
Since a 10% increase in price leads to a 40% decrease in quantity demanded, the price elasticity will be:
= - 40% / 10%
= -4.
