ANSWER
As given in question
plant’s height = 37 centimeters
it grows at a rate of 0.004 centimeter per hour of sunlight
Andrea conducts a science experiment and observes that the height of a plant depends on the amount of sunlight it receives.
the number of hours of sunlight = s
Than the equation become in the form
f(s) = 0.004s + 37
this equation shows the height of the plant .
Hence proved
Answer:
d <u>></u> 9
Step-by-step explanation:
An easy way to do these questions is to treat the >/</<u>></u>/<u><</u> symbols as if they were an equals sign.
So for this question, pretend it is d+13=22 then take away 13 from both sides which will give you d=9, then after that you'll just switch the symbol back and write your answer as d <u>></u> 9.
Hope this helps :)
Answer: The surface area of the triangular prism is 448 square millimeters.
To find the surface area, we just need to input our values into the formula that is given.
SA = 2B + Ph
SA = 2(84) + 56(5)
SA = 168 + 280
SA = 448
The final surface area is 448 mm^2.
Answer:
The correct statements regarding correlation coefficient are:
1. Its absolute value cannot exceed 1.
2. A positive value indicates a strong correlation between the two variables; a negative value indicates a weak correlation between the two variables.
3. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find b positive.
4. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find a positive.
Step-by-step explanation:
Correlation measures the strength of the relationship which exists between X and Y variables. Regression, on the other hand, helps to establish a cause and effect between a dependent variable and an independent variable.
