HElp K 12 test! Will give brainiest PLS HELP!!!!
Salsk061 [2.6K]

Answer:

1. d  2. a  3. d  4. a  5. a

Step-by-step explanation:

For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.

2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.

3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.

4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.

5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.

118 cars were sold during the month of April. 68 had air conditioning and 61 had automatic transmission. 44 had air conditioning
Dmitry_Shevchenko [17]

Answer:

88.98% probability that a randomly selected car had automatic transmission or air conditioning or both

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

37 had automatic transmission only

44 had air conditioning only

61 had automatic transmission

This already counts those with both automatic transmission and air conditioning. So 61-37 = 24 had both.

So D = 37 + 44 + 24 = 105

Total outcomes:

118 cars sold, so T = 118.

What is the probability that a randomly selected car had automatic transmission or air conditioning or both?

p = \frac{D}{T} = \frac{105}{118} = 0.8898

88.98% probability that a randomly selected car had automatic transmission or air conditioning or both
