Answer:
There are 101 marbles in each bag and 10 marbles left over
Step-by-step explanation:
We can use the modulus to find out left over. The modulus is the remainder of the division from one number by another number. For example, 7 % 2 = 1. When you divide 7 by 2, division is 3 but the remainder is 1.
1525 % 15 = 10 marbles are left over
Now, we know that 1525 - 10 = 1515 marbles are equally put into each bag. That means each bag contains
1515 / 15 = 101 marbles
Perimeter is 39 just add all sides :)
For the answer to the question above,
<span>Sample mean is given by,
x = (1/n)∑x˅i .... ˅ means sub
x = (1/5)(60 + 40 + 35 + 45 + 39)
= 43.8
z-score is given by,
z = (X - μ)/σ .... μ is population mean, σ is the standard deviation
z = (43.8 - 43.8)/8.7
= 0
</span>so the answer is zero
I hope my answer helped you.
