Scale could be one. For example, on a map, one cm can represent 10 miles
Find A ∩ B if A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}. A. {3, 4, 5, 7, 9, 10, 13, 17} B. Ø C. {7}

Answer:
C. {7}
Step-by-step explanation:
Given,
A = {4, 7, 10, 13, 17}
B = {3, 5, 7, 9}
To find : A ∩ B
A ∩ B means common in both sets of A and B
So,
A ∩ B = {7)
Answer:
1/380
Step-by-step explanation:
<u>Probability of Bob's name drawn first is:</u>
- 1/20 as there are 20 people with equal chance
<u>And probability of Laquisha's name drawn second is: </u>
- 1/19 as there are 19 people left with equal chance
<u>Probability of the two events happening is: </u>
- 1/20*1/19 = 1/380 product of individual probabilities
Yes because it doesnt have decimals or fractions
It is choice (D)
Let's set that unknown number to x.
The first step is the difference of 3 times a number and 15 --> 3x - 15
That is no less than the square of the number ' '
Now combine them
Hope that helped!
