Answer:
D. 1.30
Step-by-step explanation:
As you can see on the number line, since there are 10 markings between the marks of 1 and 2, we can divide that to get the value that each marking represents.
Hence, each marking represents a change of , which would equal to .
Therefore, A would be 1 + (3 ), which equals to 1.3.
(As for why it would be 1 <em>+ </em>(3 ), that is because we can deduce the number line grows as it goes to the right due to the main markings (0, 1, 2) also growing as they go towards the right.)
Hope this helped!
To find the unit rate, divide total miles by number of gallons:
418 miles / 16 gallons = 26.125 miles per gallon
Round the answer as needed.
The temperature was at -15 and went down -10 so now it is a -25 F
Answer:
There is a 2.17% probability that a randomly selected person aged 40 years or older is male and jogs.
It would be unusual to randomly select a person aged 40 years or older who is male and jogs.
Step-by-step explanation:
We have these following probabilities.
A 13.9% probability that a randomly selected person aged 40 years or older is a jogger, so .
In addition, there is a 15.6% probability that a randomly selected person aged 40 years or older is male comma given that he or she jogs. I am going to say that P(B) is the probability that is a male. is the probability that the person is a male, given that he/she jogs. So
The Bayes theorem states that:
In which is the probability that the person does both thigs, so, in this problem, the probability that a randomly selected person aged 40 years or older is male and jogs.
So
There is a 2.17% probability that a randomly selected person aged 40 years or older is male and jogs.
A probability is unusual when it is smaller than 5%.
So it would be unusual to randomly select a person aged 40 years or older who is male and jogs.
