High temperatures in a certain city for the month of August follow a uniform distribution over the interval 62 degrees Upper F to 87 degrees F. What is the probability that a randomly selected August day has a high temperature that exceeded 67 degrees F question mark

And for this case we can use the cumulative distribution function given by:

And for this case we can use the complement rule and the cumulative distribution function and we got:

Step-by-step explanation:

For this case we define the random variable X as "High temperatures in a certain city for the month of August" and the distribution for X is given by:

And for this case we want to find this probability:

And for this case we can use the cumulative distribution function given by:

And for this case we can use the complement rule and the cumulative distribution function and we got:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
