Answer:

34%

Explanation:

To write the fraction as a percent we need to divide 34 by 100 and then multiply by 100%, so

34/100 x 100 = 0.34 x 100% = 34%

Therefore, 34/100 as a percent is 34%

If you are an apprentice plumber earning an annual salary of $21,060, and you lay claim to 3 allowances, the amount that will be withheld from your weekly pay for federal income tax is: $7.

To obtain the correct amount to be paid, we need to use the table provided by the IRS. First note that there are 52 weeks in a year, so we need to divide your annual earnings by the total number of weeks in a year.

So, 21060/52 = $405

When we look at the table to see the chart for a person who has a weekly wage of 400 - 410, and lays claim to three allowances, we will see that the right amount that such an individual is meant to pay is $7.

Step-by-step explanation:

Recall the formula for an arithmetic sequence: [tex]a_{n} =a_{1} +d(n-1)[/tex]

Where d is the common difference and a_1 is the first term of the sequence.

You are given :

a_1=4

a_2=8

a_3=12

Next is to find the common difference d.

To find the common difference, take the next term and subtract it from the current term.

a_2-a_1=8-4=4

Let try the next term start at a_2

a_3-a_2=12-8 =4

Do you see the pattern?

The patter is going up by 4 each time. So the common difference is 4 i.e d=4

Now we just need to plug into the generalize formula above and get

[tex]a_{n}=4+4(n-1)[/tex]

The question asked for the 40th term. Plug 40 into the formula and you will get:

[tex]a_{40}=4+4(40-1)=160[/tex]

The slope of 2 and passes through the point (-8,1)  :  y-1 = 2(x+8)

what is slope ?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

The standard equation of a line in point slope form is expressed as;

so ,

y-y0 = m(x-x0)

m is the slope

(x0, y0) is the point

Given

Slope m = 5 (assumed value)

Point (-8,1)

Using the sample size relation with the standard normal distribution, the required sample size is 3032 samples.

What is Normal distribution ?

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Using the sample size relation with the standard normal distribution, the required sample size is 673 samples.

n = [(Z* × σ) / ME]²

ME = margin of error

Z* = Z critical at 90% = 1.645

Substituting the values into the equation :

n = [(Z* × σ) / ME]²

n = [(1.645 × 50.2) / 1.5]²

n = (82.6/ 1.5)²

n = 55.06

n ≈ 3032

Therefore, the Number of samples required is 3032 samples.

x represents the number of packages of coffee sold

y represents the number of packages of pastry sold

We were the cost of a package of coffee is $6 and the cost of a package of pastry is $4. If the total amount made from selling x packages of coffee and y packages of pastry is $72, then the equation representing this scenario is

6x + 4y = 72

Also, we were told that she sold 2 more packages of coffee than pastries. This means that

x = y + 2

Thus, the system of linear equations is

6x + 4y = 72

x = y + 2

We would plot these equations on the graph. The graph is shown below

The red line represents x = y + 2

The bu line represents x = y + 2

[tex]k=4[/tex].

Answer:

k = 4

Step-by-step explanation:

a) Simplify both sides of the equation.

20 + 7k = 8(k + 2)

20 + 7k = (8)(k) + (8)(2)

20 + 7k = 8k + 16

7k + 20 = 8k + 16

b) Subtract 8k from both sides.

7k + 20 − 8k = 8k + 16 − 8k

−k + 20 = 16

c) Subtract 20 from both sides.

−k + 20 − 20 = 16 − 20

−k = −4

Divide both sides by -1.

-k/-1 = -4/-1

k = 4

Given,

angle I = 54 degrees

angle FBC = 44 degrees

Recall, the sum of the angles in a triangle is 180 degrees. This means that for triangle BIC,

angle B + angle I + angle BCI = 180 degrees

54 + 44 + angle BCI = 180

angle BCI + 98 = 180

angle BCI = 180 - 98 = 82(sum of angles in a triangle)

Since lines AD and EH are parallel,

angle BCI and angle FGI are corresponding angles(They have similar positions and lie on the same side of the transversal, CI)

Thus,

angle FGI = 82(corresponding angles)

angle CGH and angle

angle CGH and angle FGI are vertically opposite angles. Vertically opposite angles are equal. Thus,

angle CGH = 82 degrees

The reason is 'vertically opposite angles'

To determine which option is a representation of the graph we need to make the numer line analysis; to make it we need to notice that the functions has zeros at the points:

once we know this we divide the number line in the following intervals:

now we need check the sign of the function in each interval, to do this we choose a value in them.

For the first interval let's take x=-4, then we have:

From the last expression we notice that the value of the function is positive at this point. Hence the firts interval have positive values for the function.

For the second interval let's take x=-1, then we have:

From the result we conclude that the function is negative in this interval.

For the third interval, let's take x=1, we have:

From the result we conclude that the function is positive in this interval.

For the fourth interval, let's take x=3. then we have:

Then the function is positive in this interval.

Finally, for the fifth interval let's take x=5, then we have:

Then the function is negative in the last interval.

Hence the line analysis is:

The y-intercept of the function happens when x=0, then we have that:

Therefore the y-intercept of the function is 0.

Once we know the information from the line analysis and the y-intercept of the function we conclude that the sketch of the graph is option B.

Two graphs of the function (with different values for the y-axis) are shown below:

This graphs confirm that option B is an approximate sketch of the graph.
