Answer:
D) 65 I believe
Step-by-step explanation:
What I did what 20 divided by 4, which gave me 5 doses per ounce. Then I multiplied 5 times 13 and that gave me 65
10-7=3 so his rate is 18 boxes every 3 hours 18/3 is 6 boxes per hour, 12-7=5 hours 5 x 6 = 30 boxes by 12pm
Answer:
The probability the code is 14z is
.
Step-by-step explanation:
Probability is calculated using the following fraction:
![\frac{number of desired outcomes}{total number of outcomes}](https://tex.z-dn.net/?f=%5Cfrac%7Bnumber%20of%20desired%20outcomes%7D%7Btotal%20number%20of%20outcomes%7D)
In this case, we are looking at three independent, combined events. This means that each pick of a number or letter does not depend on the previous event, but that the probability of each is linked, so we must multiply each probability together to get the total probability of the compete code. Since the numbers are 00 to 49, there are five total outcomes for the first number (0, 1, 2, 3, 4) and ten total outcomes for the second number (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The total outcomes for the letter selection would be 26, since there are 26 letters in the alphabet. Now, we multiply each probability together:
![\frac{1}{5}*\frac{1}{10}*\frac{1}{26}=\frac{1}{1300}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%2A%5Cfrac%7B1%7D%7B10%7D%2A%5Cfrac%7B1%7D%7B26%7D%3D%5Cfrac%7B1%7D%7B1300%7D)
Step-by-step explanation:
step 1: add the ratios
1/2 + 1/4 + 1/5 = 0.95
step 2: divide each ratio by the total sum of the ratios and multiply by a 100
(1/2 ÷ 0.95) × 100 = 52.63 rounded off equals to 53
(1/4 ÷ 0.95) × 100 = 26.31 rounded off equals to 26
(1/5 ÷ 0.95) × 100 = 21.05 rounded off equals to 21
These ratios should add up to a 100
so the ratio are 53 : 26 : 21
