Answer:
<u>Chris charges more per acre than Joe </u>
Step-by-step explanation:
Joe charges $40 to mow 2 acres.
So, Joe charges per acre = 40/2 = $20
Chris charges $30 to mow 1.2 acres.
So, Chris charges per acre = 30/1.2 = $25
∵ 25 > 20
<u>So, Chris charges more per acre than Joe </u>
There is not enough information to be to able to determine whether a geometric probability density function or a cumulative distribution function should be used.
Answer: Option C.
<u>Explanation:</u>
Geometric probability density function is the probability function which talks about the probability of two different sets which are in some way related to each other and the probability of one set affects the probability of the other set.
On the other hand, the geometric cumulative distribution function speaks about modelling number of failures before the first success in repeated independent trials. In this case none of this is clear from the statement given in the question. So it is tough to determine the function.
Answer:
6 cakes
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
-4(x-1) + 6x = 34 --- distribute the -4 by multiplying
-4x + 4 + 6x = 34
-4x + 6x + 4 = 34 --- rewrite/group like terms and combine
2x + 4 = 34 --- now you need to isolate the variable x
2x - 4 = 34 - 4 --- subtract 4 from each side
2x = 30 --- divide each side by 2 (inverse operation of multiplication)
x = 15
Then to check, plug in 15 for x:
-4(15-1) + 6x = 34
-60 + 4 + 6x = 34
-56 + 6x = 34
-56 + 56 + 6x = 34 + 56
6x = 90 ---divide each side by 6 (inverse op of multiplication)
x = 15
