Answer:
About 400 times
Step-by-step explanation:
Given
See attachment for spinner
Required
Determine the number of times an outcome of 1, 3 or 8 is expected
First, calculate the theoretical probability of 1, 3, or 8
This is calculated as:
The spinner is divided into 8 equal segments and each outcome appears once.
So, we have:
Take LCM and add
So, the expected number of times (E) is:
Approximate
<em>This means about 400 times</em>
Answer:
3, 8, and last one wont render for me
Step-by-step explanation:
Multiply 3 by every number going up and see which one is closest to 10 after being added with 2.
Its the same steps with the second question just different numbers.
Hope this helps
Branliest answer please if you don't mind
Answer:
5391.76
Step-by-step explanation:
We have a rectangle and 2 semicircles
First find the area of the rectangle
A = l*w
A = 44*88= 3872
Then we know that 2 semicircles = 1 circle
The area of a circle is
A = pi r^2
The diameter is 44 so the radius is 22
A = pi * 22^2
A = pi484
A =1519.76
Add the areas together
1519.76+3872
5391.76
