Answer:
There is a linear correlation between chest size and weight,0.8482
Step-by-step explanation:
Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.
the value of the linear correlation coefficient is r = 0.921.
i.e. there is a strong positive correlation from the value of r.
(Two tailed test at 5% level for correlation coefficient)
Test statistic t =
p value <0.00001
Since p is less than 0.05 we reject H0
a) There is a linear correlation between chest size andweight
b)-- R^2 = 0.8482 proportion of the variation in weight can be explainedby the linear relationship between weight and chest size
Answer:
i think its b
Step-by-step explanation:
well if you calculate every thing you used then subtract from all the other bills then it should tell you the answer to how much it should cost
Look at the picture.
The angle y° and 71° are Supplementary Angles. Therefore y° + 71° = 180°.
The sum of measures of these three angles of any triangle is invariably equal to 180°.
Therefore we have the equation:
Median of 10, 55, 34, 21
First we arrange number in ascending or descending
10, 21, 34, 55 in ascending.
Median is the middle number and this is between 21 and 34.
We find the average:
(21 + 34) /2 = 55/2 = 27.5
Median is 27.5.
Answer:
In a deck of 52 cards, there are 26 red cards.
The probability that the first drawn card is red:
P(A) = 26/52
Without replacement, the probability that the second drawn card is red:
P(B) = 25/51
Then, this dependent probability is calculated by:
P = P(A) x P(B) = (26/52) x (25/51) = 25/102 = 0.245 = 24.5%
Hope this helps!
