Answer:
1400 sq. ft
Step-by-step explanation:
60 min = 1 hour
280 sq. ft / 12 min = x / 60 min
x = 60 min * (280 sq. ft / 12 min)
minuets cancel out
x = 1400 sq. ft
Answer:
Step-by-step explanation:
Let's start with this. When do you think the mean would NOT be an appropriate measure of center? Well, maybe your data points are 1,2,4,1,5,3, 1,000,000. If you took the mean of that it wouldn't be anywhere near any of the numbers, and would just be in between two. So not in the center at all.
The point is you want your data set well balanced. You want about an equal number on one side as the other. So let's look at yours.
The furthest away from the middle has 11 on the left side and 12 on the right. If youw ere weighing them on a scale and took the 11 and 12 as the weight, they would be pretty close to equal. The next two are 21 and 23. Less close, but still only two away. The middle is the middle, so nothing to balance it out with. If you look at it as a whole, the right side is 3 more than the left. I would say 3 is still pretty close when you are looking at "weights" above 10. So I would say mean is a pretty appropriate measure of center.
Stats takes a lot of "gut feelings" like this. Thinking, "yeah, these are pretty close" so you'll get the hang of it pretty soon.
the approximate circumference of a lid that will fit his frying is 34.5 inches .
<u>Step-by-step explanation:</u>
Here we have , Jonathan wants to buy a lid for his frying pan. The diameter of the pan is 11 inches. We need to find What is the approximate circumference of a lid that will fit his frying . Let's find out:
We know that a lid for his frying pan is basically in shape of circle , So we consider a lid for his frying pan as a circle ! Now ,
Circumference of circle = 
, r = radius
⇒ 
⇒ 
⇒ 
, D = Diameter = 11 inches
⇒ 
⇒ 
⇒ 
Therefore , the approximate circumference of a lid that will fit his frying is 34.5 inches .
100% - 20% = 80%.
400 is 80% of what number?
Let n = the original price.
400 = 0.80n
400/0.80 = n
€500 = n
Understand?
Mark and Don have 18 and 92 marbles respectively.
<h3>What is the solution of the equation?</h3>
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.
Let the number of marbles Mark has be x.
According to the question,
Don has (5x+2) marbles.
Total number of marbles=110
Thus, the required equation is:
x+5x+2=110
6x=108
x=108/6
x=18
Mark has 18 marbles.
Don has (5*18+2)=92 marbles.
