Answer:
-0.574
Step-by-step explanation:
Subtract the two numbers to get the solution
Answer:
Srry I can’t graph it but this is how it would look like it would be a horizontal line with the x-intercept of -5
a) For x = 27:
z = 27-28/2 = -0.5
For x = 31:
z = 31-38/2 = 1.5
From the normal distribution table, P(27 < x < 31) = P(-0.5 < z < 1.5) = P(z < 1.5) - P(z < -0.5) = 0.9332 - 0.3085 = 62.47%
b) For x > 30.2:
z = 30.2-28/2 = 1.1
From the normal distribution table, P(x > 30.2) = P(z > 1.1) = 1 - P(z > 1.1) = 1 - 0.8643 = 13.57%
Answer:
PQ=6,69 units
Step-by-step explanation:
b/Sin32°=c/Sin72°
PQ/Sin32°=12/Sin72°
PQSin72°=12Sin32°
PQ=12Sin32°/Sin72°
PQ=6.69 units
Answer:
4.1 gallons per person
Step-by-step explanation:
The total consumption of fruit juice is 2.05 billion
The total population is 500 million
Therefore the average number of gallons fruit juice consumed per person can be calculated as follows
=total consumption/total population
= 2,050,000,000/500,000,000
= 4.1 gallons per person
