F = 9/5(40) + 32
F = 72 + 32
F = 105
40°C is ~105°F, and the closest would be D.
I'll get you started:
mean = np = (500)(.56) = ?
standard deviation = √npq = √(500)(.56)(.44) = ?
Note: q = 1 - p
Finish the calculations.
To find z-score:
z = (x - mean)/sd
Note: x = 250
Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.
Answer:
0.980413
Step-by-step explanation:
The table for the deaths and death rate per 100,000 population is attached below ;
73 years fall in the 65 - 74 years category ; with 1958.7 deaths (Female)
Hence, the probability of living another year is :
Number of deaths per 100,000 population ;
P(death) = 1958.7 / 100,000 = 0.019587
Probability of living another year = 1 - P(death)
1 - 0.019587 = 0.980413
Answer:

c^2=(5)^2+(12)^2-2(5)(12)cos72
Answer:
$7.50
Step-by-step explanation:
4 bottles of water cost $10, meaning that each bottle costs $2.50 (10/4 = 2.5). If 3 bottles are bought and each bottle costs $2.50, the total cost is $7.50 (3*2.5 = 7.5).
