Answer:
He is incorrect in this statement because 38 and 40 both have factors, other than 1 x itself. Prime numbers are numbers the only have 1 factor pair, and that is 1 x itself. Factors are the numbers you multiply to get the end result, and an example is 10x4=40. The factors of 40 are 8x5, 4x10, 2x20, and of course, 1x40. The factors of 38 are 2x19, and 1x38.

Answer:
<u>David will have the most cookies and he will have two cookies more than Jake</u>
Step-by-step explanation:
1. Let's calculate how many cookies will David cut with his cutter, this way:
Number of cookies = Rolls of cookie dough/Size of the segment
Replacing with the values we know:
Number of cookies = 2/(1/8)
Number of cookies = 16
2. Let's calculate how many cookies will Jake cut with his cutter, this way:
Number of cookies = Rolls of cookie dough/Size of the segment
Replacing with the values we know:
Number of cookies = 2/(1/7)
Number of cookies = 14
<u>David will have the most cookies and he will have two cookies more than Jake</u>
Answer: a) There are 42% chances that both units will meet their objectives.
b) There are 88% chances that one or the other but not both of the units will be successful.
Step-by-step explanation:
Since we have given that
Probability that the Red unit will successfully meet its objectives = 60% = P(R)
Probability that Blue unit will successfully meet its objectives = 70% = P(B)
Probability that only Red unit will be successful = P(only Red) = 18%
As we know that

Hence, there are 42% chances that both units will meet their objectives.
the probability that one or the other but not both of the units will be successful is given by

Hence, there are 88% chances that one or the other but not both of the units will be successful.
522 divide 9= 58 58=1hour 58 x 4=232 add 232 to 522 =754
