Answer:7
Step-by-step explanation:
just because
A) T(m) = -0.16m +331.3
B) T(2015) = 8.9 . . . seconds
_____
The linear regression function of a graphing calculator can find the equation of the line easily. Or, you can use the 2-point form of the equation of a line.
.. T(m) = (10.5 -14.5)/(2005 -1980)*(m -1980) +14.5
.. T(m) = -0.16(m -1980) +14.5
Answer:
Step-by-step explanation:
29 years they are combined ages the same and if this goes up 2:1 ratio every year thereafter from age 43 then to change 29:43 to make double it is x 8 43 x 8= 344 and 29 x16=464. The ages never become double.
Answer:
A. Data
Step-by-step explanation: <em>Data is a term used to describe facts, information or statistics that are collected together in order for it to be used as a reference or for analysis.</em>
An effective data collection is one of the most important aspects in research,experiments or statistics as it helps to guarantee a reliable and effective outcome.
Data collection should be done in such a way that it helps to solve the problem which is being studied or handled.
Answer:
with proportional relationships, you can simply divide the y coordinate by the x coordinate to find the unit rate: In this case, if (5,4) lies on the line then you have 5 lbs of potatoes for 4 dollars or .80 cents for 1lb of potatoes. The point (10,8) represents 10 lbs of potatoes for 8 dollars. Here you can see that dividing 8 by 10 we once again get the unit rate of .80 cents per 1 lb of potatoes.
x = lbs of potatoes and y = price(4,3)....this means 4 lbs of potatoes cost $ 33/4 = 0.75 cents per lb <== 1 lb of potatoes cost 0.75(8,6)...this means that 8 lbs of potatoes cost $ 6
