Answer:17.3964 males 7.6035 females
Step-by-step explanation:
The first way to calculate the expected uses the marginal percentages. If sex is not related to flavor preference, you would expect the same percentages of males to prefer the same flavors as females. Since overall 20.71% prefer vanilla, you would expect 20.71% of males to prefer vanilla. Now, 20.71% of 84 people is 17.3964, so this is how many males you would expect to prefer vanilla. You would also expect 20.71% of the females to prefer vanilla, which is 17.6035. So you'd expect 17.3964 males and 17.6035 females to prefer vanilla.
If Joe and Eugene are travelling in opposite directions, their total distance is 360 km.
Eugene's speed = 70 km/hour
Let Joe's speed be = x
They each travel for 3 hours, so time = 3 hours
Distance = speed * time
Hence, Joe's speed is 50 km per hour.
24 × 60 = 1,440
1,440 × 90 = 129,600
There are 129,600 pictures in a movie that is 90 minutes long.
Answer:
Option c. integers from 1 to 10 inclusive.
Step-by-step explanation:
The given sets are A = { 1, 3, 5, 7, 9 }
B = { 2, 4, 6, 8, 10 }
C = { 1, 5, 6, 7, 9 }
We have to determine A ∪ B
A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Therefore, A ∪ B is the set of all from 1 to 10 inclusive.
option C will be the answer.
