Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4

Answer:
<u>Approximately 16 tablets of medicine</u>
Step-by-step explanation:
Based on the information above , we can use a <u>Rule of Three</u> to first figure out how many mg the cat would need to ingest per day.


Now we see that the cat needs to take a daily dose of 22.5mg. Since the Tablets come at a strength of 10 mg per tablet then,

The cat would need to take 2.25 tablets per day. Since she needs to take the dose for the next 7 days then,

She would need to take<u> approximately 16 tablets of medicine</u> during the week .

Emma’s average speed in kph should be 54 kilometers per hour. I got this by putting 1 hour and 20 minutes into just minutes. which would be 80 minutes then dividing 72km by 80 minutes. Which gave me 0.9. Then multiplying 0.9 by 60 because there are 60 minutes in an hour. Which gave me 54 kph. hope I helped.
