Question??
Dr. Sox drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Sox will hit two green lights?
Explanation;
Since this is an AND situation, we MULTIPLY the probabilities.
Answer/Explanation:
First light green:
P
1
=
20
60
=
1
3
Second light green:
P
2
=
35
60
=
7
12
Both lights green:
P
=
P
1
×
P
2
=
1
3
×
7
12
=
7
36
Of course, this is assuming that there is no "green wave" policy, or the two probabilities would not be independent
Answer:
Step-by-step explanation:
given that an article in the Sacramento Bee (March 8, 1984, p. A1) reported on a study finding that "men who drank 500 ounces or more of beer a month (about 16 ounces a day) were three times more likely to develop cancer of the rectum than non-drinkers."
To support this some data collected should be given. The data should be from a sample of a large size randomly drawn from 2 groups one men who drank 500 oz or more of beer and other group not drank that much. These people medical history with cancer patients number also should have been given.
Answer:
(-5, 3)
(-2, 6)
(-4, -2)
Explanation:
To translate 5 units up means to add 5 to the y value since the y-axis dictates the vertical positioning of a coordinate. However, the x-values remain unchanged.
So all the y values are -2, 1, and -7. Add 5 to all of these.
-2 + 5 = 3
1 + 5 = 6
-7 + 5 = -2
Then re-pair them with their x-values like so:
(-5, 3)
(-2, 1)
(-4, -2)
