Answer:
C
Step-by-step explanation:
to get to 18 from 15, you add three.
You keep adding three to every number for the y values since it it a linear function. The x values went up by 1 and the y values went up by 3.
Compute the correlation coefficient for the data set. (2,19), (3,22), (4,26), (5,20), (6,35), (7,30), (9,40), (10,42), (11,35)

Answer:
The correlation coefficient of the data is 0.8679.
Step-by-step explanation:
The formula to compute the correlation coefficient is:

From the data provided compute the values of ∑ XY, ∑ X, ∑ Y, ∑ X² and ∑ Y².
The values are computed in the table below.
Compute the correlation coefficient as follows:

Thus, the correlation coefficient of the data is 0.8679.
11/50 for club, as normally 13 clubs. 2 gone. normally 52 in pack. 2 gone.
13/50 for a diamond. still 13 diamonds, but only 50 cards.
3/50. one out of four jack's are taken out. leaving 3. 50 cards in deck.

Therefore, the only statement that is equivalent to <em>"the </em><em>price decreased</em><em> by </em>
<em>"</em> is:

Given that the original price of something decreased by 1/3, it means:
the original price is reduced by one-third.
- One-third is not equal to half of the price.
- 1/3 of the original price would be
33.3% less of the original price.
- This means that the new price would be: <em><u>100 - 33 = 66% of the </u></em><em><u>original price.</u></em> This shows a reduction in price. The price would drop.
- 1/3 is more than a quarter (1/4).
<em>Any option showing or suggesting an increase is definitely the wrong answer.</em>
Therefore, the only statement that is equivalent to <em>"the </em><em>price decreased</em><em> by </em>
<em>" </em>are:
<u><em>F. The price is now </em></u><u><em>66, 2/3% </em></u><u><em>of what it was before</em></u>

To find how many degrees Celsius, divide your number in Fahrenheit by 5/9 (or approximately 0.56), then subtract 32. As an example we'll convert 90 degrees Fahrenheit into Celsius.
C = 5/9f - 32
C = 5/9 x 90 -32
C = 50.4 -32
C = 18.4
