Jet001 [13]

Answer:

Area = 88 square units

Step-by-step explanation:

The length of the blue rectangle can be found by subtracting 15 and 4, which equals 11. The width of the blue rectangle can be found by subtracting 6 from 14, which equals 8.

area = length x width

area = 11 x 8

area = 88 square units

6(x+7)+4=-8(x-5)-2 solve for x
NikAS [45]

Answer:

x=-4/7

Step-by-step explanation:

We are given an equation as

6(x+7)+4=-8(x-5)-2

and asked to solve for x

Simplify to get

Distribute 6 over x+7 and on right side -8 over x-5

6x+42+4 = -8x+40-2

Take -8x to left side to become +8x and 46 to right side to become -46

Grouping like terms

14x = 38-46 = -8

Divide by 14

x = -8/14 = -4/7

Since this is an equation, we get a single value for x

and answer is -4/7

How many 4-letter passords can be made using the letters A thought Z if...
mezya [45]

Answer:

a.)The total 4-letters passwords when repetition of letters is allowed are 456976

b.)The total 4-letters passwords when repetition of letters is not allowed are 358800

Step-by-step explanation:

Some situations of <em>probability</em> involve multiple events. When one of the events affects others, they are called dependent events. For example, when objects are chosen from a list or group and are not returned, the first choice reduces the options for future choices.

There are two ways to sort or combine results from dependent events. <em>Permutations</em> are groupings in which the order of objects matters. <em>Combinations</em> are groupings in which content matters but order does not.

How many 4-letter passwords can be made using the letters A throught Z if...

a)Repetition of letters is allowed?

There are only 26 possible values for each letter of the password (The English Alphabet consists of 26 letters). The total 4-letters passwords when repetition of letters is allowed are 26^{4} =456976

b) Repetition of letters is not allowed?

If repetition of  letters is not allowed, we can only choose 4 letters out of 26. Using the permutation equation nP_{k} =\frac{n!}{(n-k)!}

The total 4-letters passwords when repetition of letters is not allowed are 26P_{4} =\frac{26!}{(26-4)!}=26.25.24.23=358800
