Answer:

d) r=0.90

Step-by-step explanation:

When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables. A correlation nearerto -1 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation.

Correlation coefficient measures the strength of association between two variables.

It may be positive or negative.

If nearer to 1 or - there is strong correlation

Since here is it 0.90 positive and nearer to 1 out of all 4 options

option d is correct

a cell phone company offers two different monthly plans.plan a charges $41 for unlimited cell phone minutes plus $0.10 per text
tiny-mole [99]

41+0.10x = 31+0.15x

10 +0.10x=0.15x

10=0.05x

x=10/.05

x= 200 text messages


check 200*0.10 = 20 +41 =61

200*0.15 = 30+31 = 61

 they equal each other so number of texts is 200
