Answer: D) 52%
Step-by-step explanation:
G = gymnastics
B = baseball
S = soccer
G = 28%
BA = 29%
S = 19%
G and BA = 14%
BA and S = 12%
G and S = 10%
GBS = 8%
So, as we can see at the Venn diagram attached (consider every number in %)
GBS = 8
A = G and S - GBS = 10 - 8 = 2
B = G and BA - GBS = 14 - 8 = 6
C = BA and S - GBS = 12 - 8 = 4
Only G = G - A - B - GBS = 28 - 2 - 6 - 8 = 12
Only BA = BA - B - C - GBS = 29 - 6 - 4 - 8 = 11
Only S = S - A - C - GBS = 19 - 2 - 4 - 8 = 5
So, 2+6+4+12+11+5+8 = 48
100 - 48 = 52%
Answer:
There is a strong positive correlation coefficient for the relationship between data plan size 'x' and number of text messages sent 'y'
Step-by-step explanation:
In statistics, the correlation coefficient is attributed to a symbol R. Correlation Coefficient value spread over a range from -1 to +1. It shows the depth of relationship between the movement which is relative of two existing variables
From the given question;
We have the study of the relationship between the data plan size and the number of text messages sent in the U.S.
When R value is at 0 ; it illustrates and pinpoint the fact that there is no relationship between these two variables under study.
However; the R value near to +1 and -1 definitely shows the strength of the positive and negative correlation of the two variables under study.
Given that :
R = +0.97 ; we can see from above explanation that this is showing and telling us that there is a strong positive correlation coefficient for the relationship between data plan size 'x' and number of text messages sent 'y'.
Conclusion: we conclude that the large data size corresponds to the large number of text messages and the small data size corresponds to the small number of text messages.
(x+4) x 2-3(x+4)-3=0
2x+8-3(x+4)-3=0
2x+8-3x-12-3=0
-x -7=0
-x=7
x=7
The answer is 27. The square root of 81 is 9 and 9 x 3 is equal to 27.
