Answer:
84 arrangements
Step-by-step explanation:
First, we need to calculate the total number of roses that the shop owner has. We do this by adding the pink roses and the red roses that the owner has.
342 + 330 = 672 total roses
Now that we have the total number of roses we simply divide by the number of roses needed for each arrangement (8) in order to calculate the total number of arrangements that the owner can make.
672 / 8 = 84 arrangements

its just like subtracting when you add a negative number to a positive one. flip them around! makes it a lot easier.
Given:
<span>howler monkey: {15, 16, 17, 17, 17, 17, 18, 19}
</span><span>spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}
The mean of the first set (howler monkey) = (15 + 16 + 17 + 17 + 17 +17 + 18 + 19)/ 8
The sum of all weights is divided by the number of monkeys weighed (n = 8)
mean = 17
Do the same for the second set (spider monkey) = 12+ 13 + 13+ 14 + 14+ 14 +14 +16 + 16 / 8
mean = 15.75
The ratio of the two is 17:15.75 or 1.08 is to 1. </span>
