Well you do 57 time 7 and get 399 and then it says how far will she have driven so you would add the 60 and get 459 miles.
Answer:
1, 4/5,2/5
Step-by-step explanation:
y = 5x
Let y = 5
5 = 5x
Divide by 5
5/5 =5x/5
1=x
Let y=4
4 =5x
Divide by 5
4/5 =5x/5
4/5 =x
Let y=2
2 =5x
Divide by 5
2/5 =5x/5
2/5 =x
Answer:
-15
Step-by-step explanation:
3^2 - 3 x [(5^2 - 9) / 2 ]
9 - 3 x [(25 - 9) / 2]
9 - 3 x (16/2)
9 - 3 x 8
9 - 24
-15
Answer: P = 0.75
Step-by-step explanation:
Hi!
The sample space of this problems is the set of all the possible sales. It is divided in the disjoint sets:

We have also the set of sales of boat accesories
, the colored one in the image.
We are given the data:

From these relations you can compute the probabilities of the intersections colored in the image:

You are asked about the conditional probability:

To calculate this, you need
. In the image you can see that the set
is the union of the two disjoint pink and blue sets. Then:

Finally:
