The total amount of deductions from an employee’s gross pay is $83.20. If the gross pay is $378.18, what percent of their gross
Masja [62]

Answer:

22%

Step-by-step explanation:

A percent of something can be thought of as part of that thing divided by the total amount of the same thing and multiplied by 100%.

In this case, the part of the thing is part of a paycheck. The total thing is the total paycheck.

Percent=\frac{Part}{Total} *100%%

Percent=\frac{83.20}{378.18} *100=0.2200*100=22.000%

The points A(-3,6), B(8,6), C(8,-4)and D(-3,-4)are vertices of rectangle ABCD. A point is selected at random from the interior o
aleksklad [387]

Answer:

the probability that the x-coordinate of the point is negative and the y-coordinate of the point is positive  is 16.36%

Step-by-step explanation:

Assuming that each point has the same probability to be chosen  ( uniform probability distribution in the rectangle area ) then the probability of choosing a negative x-coordinate and positive y-coordinate is the ratio of the area with those requirements over the total area of the rectangle.

therefore

Ar= area of negative x-values and positive y-values = (-3)*6 = 18

AT= total area of the rectangle = [8-(-3) ]*[6-(-4)] = 110

then

probability = Ar/AT = 18/110 = 0.1636 = 16.36%

Answer:

  (i)  (x +4)^3 = x^3 +12x^2 +48x +64

  (ii)  (2m +1)^3 = 8m^3 +12m^2 +6m +1

  (iii)  (a -2b)^3 = a^3 -6a^2b +12ab^2 -8b^3

Step-by-step explanation:

Powers of a binomial have a pattern. The coefficients of the terms of the expanded product are the numbers in the corresponding row of Pascal's Triangle. Here, you want the 3rd power, so the coefficients of interest are ...

  1, 3, 3, 1

The pattern is ...

  (a +b)^2 = a^2 +2ab +b^2

  (a +b)^3 = a^3 +3a^2b +3ab^2 +b^3

The total of powers of the variable is equal to the exponent of the binomial. The powers of the first variable decrease to 0 while the powers of the second variable increase from zero.

When 'a' or 'b' is something with a coefficient, that whole term is raised to the appropriate power.

__

i) (x+4)^3 = x^3 +3·4x^2 +3·4^2x +4^3

  (x +4)^3 = x^3 +12x^2 +48x +64

__

ii) (2m +1)^3 = (2m)^3 +3·1·(2m)^2 +3·1^2·(2m) +1^3

  (2m +1)^3 = 8m^3 +12m^2 +6m +1

__

iii) (a -2b)^3 = a^3 +3·a^2·(-2b) +3·a·(-2b)^2 +(-2b)^3

  (a -2b)^3 = a^3 -6a^2b +12ab^2 -8b^3

_____

<em>Additional comment on Pascal's triangle</em>

The numbers in each row are the sums of the two numbers immediately above. For binomial expansion, you're only interested in the contents of a row. The "patterns" shown in the attachment are an extra added attraction, not particularly relevant to binomial expansion.
