The steam fitter gross pay when she works for 56 hours in a week is $1629.60

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.

For amount of money earned for working above 40 hours in a week is:

Amount = 19.40x + 0.5(19.40)(x)

Where x is time. For 56 hours:

Amount = 19.40(56) + 0.5(19.40)(56) = $1629.60

The steam fitter gross pay when she works for 56 hours in a week is $1629.60

A prior study determined the point estimate of the population proportion as 23% ( = 0.23). The analysts want to conduct a second
Flura [38]
We have:

z-score = 2.58
Proportion, p = 0.23
q =  1 - 0.23 = 0.77
Margin of error, E = 17% = 0.17

Step 1: 
Multiply p by q = 0.23 × 0.77 = 0.1771

Step 2:
Divide z-score by the margin error = 2.58 ÷ 0.17 = 15.2

Step 3:
Square the answer from step 2 = 15.2² = 230.32

Step 4:
Multiply the answer from Step 1 by the answer in step 3 
= 0.1771 × 230.32 = 40.79

The answer is the sample size is 40.79 rounded to 41

write the equation in slope intercept form of the line that passes through -1, 11 and is parallel to the graph of y = -8x + 3
lawyer [7]
<h2>Answer: The line from the question [ y = -8x + 3 ] passes through the point ( -1, 11 ). </h2>

<h3 /><h3>Step-by-step explanation: </h3>

<u>Find the slope of the parallel line</u>

When two lines are parallel, they have the same slope.

                 ⇒  if the slope of this line = - 8

                      then the slope of the parallel line (m) = - 8

<u>Determine the equation</u>

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                               ⇒  y - 11  =  - 8 (x - (-1))                                

                                ∴  y - 11  = - 8 (x + 1)

We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:

                      since   y - 11  = - 8 (x + 1)

                                        y  = - 8 x  + 3

The line from the question [ y = -8x + 3 ] passes through the point ( -1, 11 ).

Which is zero of the polynomial expression 7x+21
swat32

Answer:

The zero is x = -3

  1. Use the Rational Zero Theorem to list all possible rational zeros of the function.
  2. Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial.
  3. Repeat step two using the quotient found with synthetic division.
