Answer: b) τ = 0.3
Step-by-step explanation:
Given the data :
Amount of salt (x)____% body fat(y)
0.2 _______________20
0.3 _______________30
0.4 _______________22
0.5 _______________30
0.7 _______________38
0.9 _______________23
1.1 ________________30
The correlation Coefficient as obtained from the online pearson correlation Coefficient calculator is 0.3281 = 0.3 (to one decimal place) which implies that a weak positive correlation or relationship exists between the preferred amount of salt taken to the percentage body weight of an individual. This is because the value is positive and closer to 0 than 1. The closer the weaker the degree of correlation. With positive values implying a positive relationship (that is an increase in variable A leads to a corresponding increase in B and vice-versa).
Answer:
3.9512
Step-by-step explanation:
You can find the answer by simply putting the value of natural log in a calculator.
ln (52) = 3.951243719
ln (52) = 3.9512 (rounding to nearest 10000th)
Which is the value of natural log of 52 rounded to the nearest ten thousandth
__________________________________________________________
<em>Note: To round off, we will see the number after the 10000th is greater than 5 or not, since the number is 4 and it is less than 5 so we will not raise the 10000th number which is 2</em>
Answer:
The line segments AB and CD are perpendicular to each other.
Step-by-step explanation:
Segment AB falls on line 2x − 4y = 8.
Rearranging the equation into slope-intercept form we get, ............. (1)
Therefore, slope of the line segment AB is
Now, the segment CD falls on line 4x + 2y = 8.
Rearranging the equation into slope-intercept form we get, ............. (2)
Therefore, the slope of the line segment CD is, N = - 2
So, M × N =
Hence, we can conclude that the line segments AB and CD are perpendicular to each other
Step-by-step explanation:
7 - 3b-2(0 + 3 - 2b)
To simplify the expression in the box, Fatua used
these steps:
Step 1:7 - 3b-2(3 - 3b)
Step 2:7 - 3-6-36-
Step 3: -13 - 66
Did Fatua calculate correctly? if nnot, in what step
did she make her FIRST mistake?
