Which of the following demonstrates how the 20 is calculated using the combination pattern

UNO [17]

The combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3

<h3>Permutation and Combination</h3>

While combination has to do with selection, permutation has to do with arrangement.

According to the combination rule

nCr = n!/(n-r)!r!

The expression that gives the result of 20 is expressed below;

6C3 = 6!/(6-3)!3!

6C3 = 6!/3!3!

6C3 = 6!/6*6
6C3 = 720/36
6C3 =20

Hence the combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3

The speed limit is 50 miles per hour. Kyle is driving to a baseball game that starts in 2 hours. Kyle is 130 miles away from the

Marizza181 [45]

Answer: No. Kyle will arrive late

Step-by-step explanation:

The only speed limit is 50 miles per hour.

Kyle must cover 130 miles.

His travel time = 130/50 = 2.6

2 hours + (0.6 of 60 minutes )

2 hours + (36 minutes)

i.e kyle needs 2hours 36 minutes to cover 130 miles

And since the baseball starts in 2 hours, kyle will be late. Thus, the answer is No

To be considered for pilot school, 12 students took a spatial reasoning test that resulted in this list of scores. Find the valu

lord [1]

Answer:

the 90th percentile is 145

Step-by-step explanation:

Data provided:

152 121 130 143 122 101 137 98 138 127 145 117

Number of students considered, n = 12

To find:

90th percentile

Now,

Step 1 : Arrange the data in ascending order

98, 101, 117, 121, 122, 127, 130, 137, 138, 143, 145, 152

Step 2 : Compute the position of the 90th percentile

position of the 90th percentile, i = (90% × n)

Thus,

i = 0.90 × 12

i = 10.8

Now,

Step 3 : Since, the index i is not an integer, round up to the nearest integer

i.e i = 11

Therefore,

The 90th percentile is the value in 11th position,

i.e 145
