Question 4

there are 39 chocolates in a box, all identically shaped. there 16 are filled with nuts, 13 with caramel, and 10 are solid

chocolate. you randomly select one piece, eat it, and then select a second piece. find the probability of selecting a nut

chocolate followed by a caramel chocolate.

The probability of selecting nut chocolate followed by a caramel chocolate is

=(15/38)(13/39)

=15/144

=.1315

Step-by-step explanation

The probability of selecting first piece as a nut chocolate is

Nut chocolate = 16

total chocolates = 39

probability of  nut chocolate=16/39

The probability of selecting first piece as a nut chocolate is 15 out of 38

=15/ 38

probability of caramel chocolate = 13/39

then 15/38 th time you select a nut chocolate by caramel

So

=(15/38)(13/39)

=15/144

=.1315

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
