Answer:
(e) 0.75
Step-by-step explanation:
The correlation coefficient is not affected by translation or scaling of scores. Converting them from "raw scores" to z-scores does not affect their correlation.
The correlation coefficient of the z-scores is 0.75.
Answer:
I believe it's 24
Step-by-step explanation:
because 2+1 is 3 and then 3 times 8 is 24
Answer:
720.8
Step-by-step explanation:
(2.6 × 106) + (4.2 × 106)
275.6 + 445.2
720.8
21
Step-by-step explanation:
because
7b
=7 × b
=7 × 3(b=3)
=21
Equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
<u>Step-by-step explanation:</u>
We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is :
,
where m = slope of line & c = intercept.
Let's calculate slope m :
Consider any two given points , let's have ( 4,0) & (3,30) :
Slope = m
⇒ m = 
⇒ m = 
⇒ m = 
So , equation now becomes :
⇒ 
at x = 0 we have y = 4



Therefore, equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
