Answer: <em>r</em> represents a significant linear correlation.
Step-by-step explanation:
GIven : Linear correlation coefficient: r = 0.543
Sample size: n= 25
Significance levle: 
Degree of freedom : n-2 = 25-2=23
Now, we check <em>r</em> critical value table for value with df = 23 and .
Critical value = ±0.396 [From <em>r</em> critical value table]
Since r = 0.543 > 0.396, that means there is significant linear correlation.
Hence, <em>r</em> represents a significant linear correlation.
Answer:216
Step-by-step explanation:
We let x to represent the number of other nuts
Peanut : other
5 : 3
360 : X
Then we cross multiply
5 × x = 360 × 3
5X = 1080
Divide bothside by 5
5X/5 = 1080/5
X = 216
Therefore the number of other nuts in the can is 216.
Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.
ANSWER : 9 over 4
or 2 and 1/4
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*3 over 2 x 3 over 2 is 3/2 x 3/2* << this is for me to remember
Okay so multiplying fractions means for us to multiply across. That means if we line the fractions, we multiply. Like this
3 x 3
----- ----- 3 times 3 is = 9
2 x 2 2 times 2 is = 4
9 over 4 is the same thing as 2 and 1/4 << FRACTION
^^
WHOLE
Hope I helped (:
