There is a spinner with 14 equal areas, numbered 1 through 14. If the spinner is spun one time, what is the probability that the
1 answer:
Answer:
Probability that the result is a multiple of 4 or a multiple of 3= 0.428
Step-by-step explanation:
The spinner is divided into 14 equal areas.
Probability of an event=
For favourable events,result should be a multiple of 3 or 4.
All the possible outcomes are=1,2,3,4,5,6,7,8,9,10,11,12,13,14
- Multiples of 3=3,6,9,12
- Multiples of 4=4,8,12
Hence the favourable outcomes are=3,4,6,8,9,12
Number of favourable outcomes=6
Total number of outcomes=14
Probability=
=0.428

Answer:
or 2.738
Step-by-step explanation:
Let’s just look at the triangle on the top with the on the top and x on the bottom. (Basically the top half to the equilateral triangle)
There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem:
We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b= or
Plugging these values into the equation:
x^2+ (\frac{\sqrt{10} }{2})^{2}=\sqrt{10} ^{2}
This approximately equals 2.738
