Answer:
=57.89%
Step-by-step explanation:
The total number of golf ball is 4+8+7 = 19
P (red or yellow) = number of red or yellow
------------------------------------
total number of golf balls
= 4+7
-----
19
=11/19
Changing this to a percent means changing it to a decimal and multiplying by 100%
= .578947368 * 100%
=57.8947368%
Rounding to two decimal places
=57.89%

First find the circumference of the circle:
= Circumference.
= 
Find the ratio of the angle in relation to the entire circle:
is what we have. So:
Use the ratio and multiply the circumference to find the length:
= 
Round answer to the hundredth:
Answer:
To convert mixed number 10 3/17 to improper fraction, you follow these steps:
First, note that 10 3/17 is a mixed number, also know as mixed fraction. It has a whole number and a proper fraction. The numbers in the mixed fraction are defined as follow:
10 = whole number
3 = numerator
17 = denominator
Multiply the whole number by the denominator
10 × 17 = 170
Add the product from Step 1 to the numerator
170 + 3 = 173
Write answer from Step 2 over the denominator
173/17
The mixed number 10 3/17 converted to improper fraction is therefore :
173/17
Step-by-step explanation:
Answer: 19 with no remainder
Step-by-step explanation: I'm sorry, I was not able to do it on paper, but the remainder would be 0. I hope the image below helps you understand how to do long divison.
Answer:
Ok. So we have 12 different styles of watches to choose from, so that means that the total number of combinations of styles for 5 boys is 12*12*12*12*12, since each boy has his pick of 12 options.
The way to answer this question is by way of the complementary rule: We want the number of ways that the boys can all have different styles. So the first boy to pick has 12 options available to him, the second boy has 11 options available to him, the 3rd boy has 10 options available to him, so on and so forth.
So the probability that the boys all have different watches is (12*11*10*9*8)/12^5= .3819.
To find the probability that at least two boys have the same style would just be 1 -.3819 = 6181
