Determine whether the following problem involves a permutation or combination. (It is not necessary to solve the problem.) How many different 33-letter passwords can be formed from the letters Upper QQ, Upper RR, Upper SS, Upper TT, Upper UU, Upper VV, and Upper WW if no repetition of letters is allowed?

Answers

Answer 1

Answer:

Answer:

Permutation

Step-by-step explanation:

Since we are talking about passwords the order of the letters matters, i.e, the pasword UpT is different to the pasword pUT. Therefore, the problem involves all the permutations of 33 letters, from the given letters, where no repetitions of letters are allowed.

Find the mode.19, 1, 17, 19, 3, 20, 5, 2

A. 10.75
B. 11
C. 19
D. 20

Answers

The answer is C. 19

Rearrange the series from the lowest to the highest value:
1, 2, 3, 5, 19, 19, 20

The mode is the value that occurs most frequently. Number 19 is found twice, so it is the mode.

The correct answer is C. 19

Can you use the sss postulate or the sas postulate to prove ABC and AED are congruent ?

Answers

Answer:

Neither SSS nor SAS apply.

Step-by-step explanation:

SSS (Side-Side-Side)-

If three pairs of sides of two triangles are equal in length, then the triangles are congruent.

SAS (Side-Angle-Side)-

If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent.

It given in the picture that,

AC = AD (Side)
BC = DE (Side)
m∠BAC = m∠EAD (Angle)

So, ΔABC and ΔAED will not be congruent by either SSS or SAS.

give a stripped down answer without going through a full explanation.

The number of combinations of 3 cows out of 7 is (7·6·5) / 3! = 35 .

The number of combinations of 2 pigs out of 4 is (4·3)/2 = 6

The number of combinations of 10 sheep out of 10 is 1 .

The number of ways he can select his animals is (35 · 6 · 1) = 210 .
