Answer:
Step-by-step explanation:
Given: A landscaping company charges $45 per cubic yard of mulch plus a delivery charge of $26.
To find: A linear function which computes the total cost (in dollars) to deliver
cubic yards of mulch.
Solution:
A landscaping company charges $45 per cubic yard of mulch.
The company also charges a delivery charge of $26.
To find a linear function which computes the total cost (in dollars) to deliver
cubic yards of mulch, we need to add the total cost for mulch and the delivery charge together.
Total cost for cubic yards of mulch
Delivery charge
Now,
Therefore, the linear function which computes the total cost is .

Hello,
First you have order all the number least to the greater. That gives 30, 75, 80, 85, 85, 95, 95, 100, 100, 110.
Afterwards you have to find the median. Why ?
I will explain you. It's because the median is robust. In fact, it can't be influenced by extreme values (example : 110) but the mean yes. So the mean won't be accurate.
"Then why don't you choose the mode ? " you will ask me. That's because the mode takes the number which appears most often in a set of numbers. It couldn't be accurate at all. It will be useless for this set of numbers.
Furthermore, here there are 3 numbers which appears the most ( 2 times for each) : $85, $95 and $100. Which one will you take ?
Therefore the median is the most suitable and the most accurate to know the center because it is robust.
Now, let's find the median :
There are 10 values, so the median will be the average of the 5th and 6th values.
5th value = 85
6th value = 95
Therefore the median is 90.
Hope this helps !

Answer:
The area = 182.52 sq units.
Step-by-step explanation:
- Area of regular polygon can be found by splitting into smaller triangles.
- Each triangle has base as side of polygon and vertex as center of polygon.
now consider ΔOAB,
we know ∠AOB = ° =72°
as ∠AOD = (∠AOB)/2 = 36°
Now we know AD=AB/2 = =5.15 m
using trignometric relation tan(∠AOD) =
⇒OD = =
AREA OF TRIANGLE = BASE × HEIGHT /2
area of ΔOAD = × 5.15 ×
=
<u>As there are 10 such triangles like </u>ΔOAD
Total area =10×
= 182.525447428574
