Answer: The description are as follows:
Step-by-step explanation:
Correlation coefficients is a statistical measure that measures the relationship between the two variables.
(a) r = 1, it means that there is a Perfect positive relationship between the two variables. If there is positive increase in one variable then other variable also increases with a fixed proportion.
(b) r = -1, it means that there is a perfect negative relationship between the two variables. If there is positive increase in one variable then other variable decreases with a fixed proportion.
(c) r = 0, this is a situation which shows that there is no relationship between the two variables.
(d) r = 0.86, this is a situation which shows that there is a fairly strong positive relationship between the two variables.
(e) r = 0.06, it is nearly zero which represents that either there is a very minor positive relationship between the two variables or there is no relationship between them.
(f) r = -0.89, this is a situation which shows that there is a fairly strong negative relationship between the two variables.
Answer:
b
Step-by-step explanation:
It would be B because 64.35/7.15=9 so e=9
Answer:
Loss = 16.67%
Step-by-step explanation:
Assume cost price(CP) of 1 article = x
Therefore cost price of 25 articles = 25x
Given cost price of 25 article = selling price of 30 articles
Clearly, it is a loss.
Selling price(SP) of 30 articles = 25x
Look at the picture.
We have 3 cuboids. The formula of a volume of a cuboid is:
V = Length × Width × Height = lwh
The cuboid 1 are congruent to the cuboid 2.
<h2>1&2</h2>
l = 9 in, w = 10 in, h = 10 in
V = (9)(10)(10) = 900 in³
<h2>3</h2>
l = 6 in, w = 10 in, h = 10 in
V = (6)(10)(10) = 600 in³
The volume of the composite prism:
V = 2(900) + 600 = 1800 + 600 = 2400 in³
