To do this, you simply need to substitute in 9 for n in the expression.

15 - n
= 15 - (9)
= 6

Hope this helps! :)

At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F. Which statement describes the temperature?
wlad13 [49]

Answer:

At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0

Step-by-step explanation:

At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F.

We can say that −3.6 lie on the LHS of a number line while 43.7 lie on RHS of the number line and 0 at the mid.

43.7°F is above 0 and 3.6°F is below 0.

At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0 . Hence, the correct option is (d).

There are 7 cherries and 3 grapes in a bag. What is the pobability of selecting 2 grapes at random without replacement?
dlinn [17]

Answer:

1/15

Step-by-step explanation:

7+3 = 10 items in the bag

P(grape) = grapes/total

                3/10

No replacement

7 cherries 2 grapes = 9 items

P(grape) =  grapes/total

                    2/9

P(grape, no replacement, grape) = 3/10*2/9

                                                       =1/15
