There are two answers to this question
the first possible answer is 5, 6, and 7 and the second possible answer is -4, -3, and -2
Step-by-step explanation:
let the three numbers be (x-1), x, and (x+1)
the product of the smallest and largest number is 17 more than 3 times the middle number, or
(x-1)(x+1) = 3x+17, or
x^2-1 = 3+17, or
x^2-3x-18 = 0
(x-6)(x+3) = 0
So x = 6 or -3
Then just subtract one and add one to get the other integers. the three numbers are 5, 6, and 7 or -4, -3, and -2
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
It’s not scaled. You can see it’s not the same shape as image A. 1 is only added to the height. If a shape is scaled, then the shape will remain the same, however it’s size will not. Therefore, the answer is “not a scaled copy of image A because 1 is added to the height”
Step-by-step explanation:
Fraction of work done by Gardner in 1 hr = 1 / 5
Fraction of work done by Gardner and helper in 1 hr = 1 / 4
Fraction of work done by helper in 1 hr
= 1 / 4 - 1 / 5
= 1 / 20
<u>Time required by helper to complete work</u> :
= <u>20 hours</u>
