Answer:
C. 20
Step-by-step explanation:
The order in which the members are selected is important. The first one selected is the president and the second is the vice president.
So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this problem:
2 people are going to be chosen from a set of 5. So
So the correct answer is:
C. 20
2 out of 4 statements supported the data above. This are:
JP Morgan Chase Tower has more height per story than the Key Tower.
-
This is true. Comparing the height in ft, JP
Morgan Chase has a height of 1,002 ft. It is higher than the Key tower which is
947 ft only.
The Key Tower has
the least height per story.
-
Looking at its height, this is the least. It only
stands at 947 ft as compared to others that are more than 1,000 ft
Answer (4):
a=ub/k because
u=ak/b (starting equation)
ub=ak (multiply b to both sides)
a=ub/k (divide both sides by k)
Answer (6)
x=g+c-y because
g=x-c+y (starting equation)
x+y=g+c (add c to both sides)
x=g+c-y (subtract y from both sides)
Answer:
See explanation
Step-by-step explanation:
Simplify left and right parts separately.
<u>Left part:</u>
<u>Right part:</u>
Since simplified left and right parts are the same, then the equality is true.
When x = 0 y = a(b)^x = a which is the y intercept
so as the y-intercept = 3 a must be = 3.
