Answer: strong positive correlafion between data plan size 'x' and number of text messages sent 'y'
Step-by-step explanation:
'R' in statistics is used to denote correlation Coefficient. The correlation Coefficient is a value which ranges between -1 to +1. It tells us the level of relationship or correlation which exists between the relative movement of two variables, in this case the relationship between data plan size and the number of text messages sent in the US. R value of 0 depicts that no relationship exists between the two variables, R value closer the R value is to +1 and - 1 depicts the strength of positive and negative correlation of the two variables respectively.
A R value of +0.97 in the context above, depicts a strong positive correlation between data plan size and number of text messages sent in the US. That is large data size usually corresponds to large number of text messages and vice versa.
Out of the six, only “u” wouldn’t work so the answer is d. 5

Answer:
3rd one, 4th one, 1st one, 2nd one
Step-by-step explanation:
1st one - 2.6
2nd one - (-3.125
)
3rd one - 10.35
4th one - -2.95
75÷25%
25%=0.25
75÷0.25
=300
Your answer is 300
Answer:
angle BAD = 180 -2x
angle BCD = x given
angle BCD is an inscribed angle
angle DOB = 2 (angle BCD)
angle BAD = 180 -angle DOB 2 tangent theorem
