3/4 divide by 5 is equal to 3/20
Answer:
Step-by-step explanation:
Given that for a biology project, you measure the weight in grams and the tail length in millimeters of a group of mice.
The correlation is r = 0.9
If you had measured tail length in centimeters instead of millimeters, what would be the correlation?
For this we must understand the meaning of correlation and formula
Correlation is a measure of linear association between the two variables and always lie between -1 and 1
This is got by dividing covariance of (x,y) by product of std deviation of x and y
So because we changed the units of length correlation coefficient would not change.
It would remain the same as 0.90
Answer:
the last one
Step-by-step explanation:
because the distance/length formula is applied here so you just need to rearrange the coordinates in to the formula
Answer:
100-5.25x 100-5.25(15)= 22.25
Step-by-step explanation:
<h2>
Hello!</h2>
The answer is:
The expression for the number of sweets that Sara and Tim have now, are:
<h2>
Why?</h2>
To write the expressions for the number of sweets that Sara and Tim have now, we need to follow the next steps:
Sara starts with 24 sweets and Tim starts with 24 sweets
Then, Sara gives Tim x Sweets
Then. Sara eats 7 of her Sweets
Then, Tim eats half of his sweets
So, the expression for the number of sweets that Sara and Tim have now, are:
Have a nice day!
