A waste management service attempts to design routes so that each of their trucks pick-up on average
four tons of garbage or less. A garbage collector believes, however, that he averages picking up more
than four tons of garbage per day and decides to perform a hypothesis test.
Identify a Type II error in the context of this hypothesis test.

a) Concluding that the garbage collector picks up on average more than 4 tons of garbage per day when,
in fact, he doesn’t.
b) Not concluding that the garbage collector picks up on average more than 4 tons of garbage per day
when, in fact, he does.
c) Concluding that the garbage collector picks up on average 4 tons of garbage per day when, in fact, he
picks up more.
d) Not concluding that the garbage collector picks up on average 4 tons of garbage per day when, in fact,
he does.

I'm confused with the wording but my guess is between B and C

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

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!

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
