The greatest number of orange beads and blue beads bracelets will be 6.
Step-by-step explanation:
Here you find the largest factor shared by the two numbers : 72 and 78. This is the same as finding the G.C.F of a set of numbers.In finding the greatest common factor, list the prime factor of each number and multiply the factors that both numbers have in common. In this case, it will be:
72 78 --------------divided by 2
2 36 39 --------------divided by 3
3 12 13 --------------no common divider
The greatest number of orange beads and blue beads bracelets will be 2*3=6

Students who receive a grade of at least a C must have a minimum score of 50.38.
<h3>Calculation of the minimum score</h3>
We may assume that the cut-off will be below 67.66 % because that percentage is more than 50%.
To get the value of 67.66 - 50 = 17.66, we must search in a regular normal table.
Hence, A z value of 0.458 will cause that value to occur.
Next, increase the standard deviation of 9 by 0.458.
The result is 4.122.
This indicates that the threshold for a student earning a C or higher is the mean minus 4.122.
So, the final result is 54.50-4.122 = 50.38.
