Answer:
$230n-$2100
Step-by-step explanation:
Profit=revenue-cost
Cost=$2100+$130×n
Revenue=$360×n
Profit=$360n-($2100+$130n
=$360n-$2100-$130n
=$230n-$2100
The arc length of the partial circle is 7.5π
<h3>Calculating arc length</h3>
From the question, we are to determine the arc length of the partial circle
The length of an arc can be calculated by using the formula
Where is the length of the arc
is the angle subtended
and r is the radius
From the diagram,
θ = 270°
r = 5
Putting the values into the equation, we get
OR 7.5π
Hence, the arc length of the partial circle is 7.5π

Answer:
A,E and F
Step-by-step explanation:
Answer:
To understand the difference consider the figure below.
Standard deviation is square root of variance. Larger standard deviation means larger variance which means larger spread of distribution. So data set A has wider and flatter spread with more data in both tails as compared to data set B. Smaller standard deviation of data set B means data is more clustered around the mean.
