Answer:
<u>The correct answer is 130.9 kilograms.</u>
Step-by-step explanation:
We want to calculate what is the result of 7.7 kilograms multiplied by 17 and the answer should be in kilograms
Result = 7.7 kilograms * 17
Result = 7.7 * 17
Result = 130.9
Result = 130.9 kilograms
<u>The result of the multiplication of 7.7 kilograms by 17 is exactly 130.9 kilograms</u>
So 3 bus tickets 3(64) = $192
and 4 train tickets 4(82) =$328
add them together 192+328 =520
it would cost $520 to buy 3 bus tickets and 4 train tickets
In this item, we have the mean incubation period of 23 days and the standard deviation is 22 days. We use z-score to determine the unknown in each of the items.
(a) less than 21 days.
z-score = (23 - 21) / 22 = 1/11
This translates to a percentage of 53.6%
(b) z-score for 19 days.
z-score = (23 - 19) / 22 = 2/11
This translates to a percentage of 57.2%.
z-score for 23 days.
z-score = (23 - 23)/ 22 = 0
This translates to a percentage of 50%.
The difference between the two numbers is only 7.2%
(c) z-score of 25.
z-score = (23 - 25)/ 22 = -1/11
This translates to a percentage of 42.3%.
Then, subtract this value from 100 to give us the final answer of 57.2%.
