Answer:

<em>588 cm²</em>

Step-by-step explanation:

<em>24 × 7 + 30 × 7 + 2(24 × 18) + 18 × 7</em> = 7(24 + 30 + 18) + 2 × 42 = 7 × 72 + 84 = 504 + 84 = <em>588 cm²</em>

Consider the vector add = a + b = [13 12 11 10 10] and sub = a - b = [-11 - 6 - 14 8]. Find the vector a and b.
prisoha [69]

Answer:

a = [1   3   5   7   9] and b = [12   9   6   3   1]

Step-by-step explanation:

The addition of two vectors a and b is defined as

a + b = [13   12   11   10   10]                .... (1)

The subtraction of two vectors a and b is defined as

a - b = [-11   - 6   - 1   4    8]                 .... (2)

After adding (1) and (2), we get

(a + b) + (a - b)= [13   12   11   10   10] + [-11   - 6   - 1   4    8]

On simplification we get

2a = [13-11   12-6   11-1   10+4   10+8]

2a = [2   6   10   14   18]

Divide both sides by 2.

a = [1   3   5   7   9]

Substitute the value of vector a in equation (1).

[1   3   5   7   9] + b = [13   12   11   10   10]

Subtract vector a from both sides.

b = [13   12   11   10   10] - [1   3   5   7   9]

On simplification we get

b = [13-1   12-3   11-5   10-7   10-9]

b = [12   9   6   3   1]

Therefore the vectors a and b are defined as a = [1   3   5   7   9] and b = [12   9   6   3   1].

How can you check that you have correctly convert frequencies to relative frequencies?
vovikov84 [41]
You could add up all the relative frequencies to make sure that you have 100% accounted for.

The relative frequency is the percent out of 100% for a particular item. If you have found the relative frequency for all items, it should equal 100%.
