There are 8 choices for the first painting on the wall, 7 choices for the second, and so on, down to three choices for the sixth. Our result is thus 8*7*6*5*4*3=20,160. C is the correct answer.
a) Negative correlation
Negative correlation corresponds to points that move down as you go from left to right on the scatter plot.
b) Positive correlation
Positive correlation corresponds to points that move up as you go from left to right on the scatter plot.
c) No correlation
Scattered points on the scatter plot make no relationship.
Answer:
A:∑j=15(2j−5)
Step-by-step explanation:
a = -3
d = -1 - (-3) = -1 + 3 = 2
j-th term: a + (j-1)d
-3 + (j - 1)(2)
-3 + 2j - 2
2j - 5
Here is a scenario:
Mark recorded the following bowling scores for his last 9 games:
110, 92, 86, 203, 74, 105, 97, 112, 99
What was his mean score?
What was his median score?
Which of these better represents his bowling score for the last nine games?
<u>The probability is </u><u>1/12</u>
The probability of choosing a nickel is 9/18 = 1/2. The probability of choosing a dime is 3/18 (because there are 3 dimes and since there is replacement, we still have 18 total coins to choose). With these, we get: (1/2) * (3/18) = 3/36 = 1/12
