Multiplying by 1 keeps it the same. A number greater than 1 would be an increase and a number below 1 would be a decrease.
The decrease is 2.7% which is written as 0.027 as a decimal.
Subtract that from 1:
1 - 0.027 = 0.973
The multiplier would be 0.973

Answer: A) 13
<u>Step-by-step explanation:</u>
Mean - 1 SD: 20.2 - 2.4 = 17.8 --> (18)
Mean + 1 SD: 20.2 + 2.4 = 22.6 --> (23)
Now, find the values on the histogram for 18 through 23:
2 + 3 + 4 + 3 + 1 + 1 = 13
We subtract the area of the fountain (a(f)) from the total area of the fountain + walk (a(t)), to find the area of the walk (a(w))
diameter of fountain = 10 so r = 5
a(f) = pi*r^2 = pi*25 = 78.5
r of fountain + walk = 5 + 3 = 8
a(t) = pi*r^2 = pi*64 = 200.96
a(w) = a(t) - a(f) = 200.96 - 78.5 = 122.46 square feet
Answer:
There are 8 friends and the presents costs $30,000
Step-by-step explanation:
Let x be the number of students and y be the price of the present. Their contributions can be expressed as:
#Make y the subject in equation i then substitute in ii:
Hence, there are 8 friends and the present is priced at $30,000
