Hey there! :)
Answer:
y + 4 = 5/2(x - 2)
Step-by-step explanation:
The point-slope form of a line is:
Where m = slope
= y-coordinate of a point
= x-coordinate of a point.
Therefore:
y - (-4) = 5/2(x - 2)
Simplify:
y + 4 = 5/2(x - 2)
Perimeter: 2w+2l
We know the width and the perimeter, which is 18 and 76, so let's plug it in.
76=2(18)+2l
76=36+2l isolate the variable x!
40=2l
20=l
every length is 20 inches.
Answer:
5.2 metres
Step-by-step explanation:
v = pi. r^2 . h
4.1 = 3.1416 × 0.25 * h
h = 5.22 m
Answer:
(b) 19% is a parameter, 22% is a statistic.
Step-by-step explanation:
-A parameter is defined as characteristic of a population under study.
In this case , the population is all cars manufactured and the characteristic of whiteness is exhibited by 19% of them.
#A statistic is a characteristic of sample.
-In this case the sample size is 100 and the statistic is 22% of them are white.
=>A statistic is usually taken or used as a representation of the entire population.
I am going to say the cheapest would be 65$ would be the answer. Because if you want it to be shipped too you would add 7.25$ to 65$ to what you are paying for. And taking 10 dollars off (subtracting) you would get 62.25$ But if you would take 65$ from you buying it and used the coupon you would have to pay 55$ The cheapest way is to buy that item (the item costs 65$) and use the 10% off coupon.
