Answer:
right angle?
Step-by-step explanation:
Answer:
The answer is 350 points
Step-by-step explanation:
The Area of a circle is πr∧2
The problem states that in the attempts, you never hit the outermost ring in the 10 attempts so we need the area of the 1cm and 2cm circles
Area of the 1st circle; π X 1∧2 = π
Area of the Second circle; π X 2∧2 = 4π
We also need the area which is the difference between the area of the 1cm and 2cm circle
4π - π = π
Points 50 = π/4π = 1/4
points 30 = 3π/4π = 3/4
For one attempt,
E(x) = 50 x 1/4 + 30 x 3/4
= 12.25 + 22.5
= 34.75
This is approximately 35
Therefor, 10 individual attempts will be 10 x 35 = 350
Kian has to work with 6 square inches
Step-by-step explanation:
Given that the logo has to be created in a rectangular shape
Length = 3 inches
Width = 2 inches
We have to calculate the area of the given space to find out that how much area Kian will work with.
So,
Hence,
Kian has to work with 6 square inches

9) 35% of the 12,000 are 50-64 years old.
12,000 x 0.35 = 4,200
4,200 people were 50-64 years old
10) 25% of 596 people are over 64 years old
596 x 0.25 = 194
194 people were older than 64
11) yes, he is correct because 450 x 10%=45 and 450 x 30%=135
