A computer repair shop charges a flat fee of $10.95 and then $24.90 per hour.
A customer paid $147.90 for computer repairs.
How many hours did the shop work on the customer's computer?
Enter your answer as a decimal in the box.
Shop work on the customer's computer for 5.5 hours.
Given,
Charge is flat fee of $ 10.95
and, then $24.50 per hour.
And, to find the number of hours if customer paid $147.90.
Now, According to the question:
Let shop work on computer for x hours .
Then, Amount paid = 10.95 + 24.90x
So, if customer paid $147.90
then, 147.90 = 10.95 + 24.90x
24.90x = 147.90 - 10.95
24.90x = 136.95
x = 136.95/ 24.90
x = 5.5
Hence, Shop work on the customer's computer for 5.5 hours.

Find the equation of a line parallel to 2x-2y=-4 that passes through the
point (3,9).
The line which is parallel to 2x-2y=-4 that passes through the
point (3,9) is x-y = -6.
Given that, 2x-2y = -4 passes through the point (3,9) then we have to find the equation of a line which is parallel to the given equation of line.
Let's proceed to find the equation of the line.
The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).
Using the slope-intercept formula, the equation of the line is:
y = mx + b
where,
m = the slope of the line
b = y-intercept of the line
(x, y) represent every point on the line
x and y have to be kept as the variables while applying the above formula.
2x-2y = -4
-2y = -4-2x
y = -4/-2 - 2x/-2
y = 2+x
y = x+2
On comparing with y = mx+b
m = 1 and b = 2
As the lines are parallel then the slope of other line will also be same i.e., m = 1
The point from which it is passes is (3,9)
⇒ x₁ = 3 and y₁ = 9
y-y₁ = m(x-x₁)
⇒ y-9 = 1(x-3)
⇒ y-9 = x-3
⇒ y = x-3+9
⇒ y = x+6
⇒ x-y = -6
Therefore, the line which is parallel to 2x-2y=-4 that passes through the
point (3,9) is x-y = -6.
Hence, x-y = -6 is the required answer.

Suppose the heights of adult American males are normally distributed with a mean of 66.9 inches and a standard deviation of 4.33. What would be the upper boundary, in inches, of a symmetric, centered interval that contained all the sample averages (from samples of size 167) that are within 0.92 standard deviation units of the mean? Round to the nearest hundredth.
Using the normal distribution, the upper boundary, in inches, of a symmetric and centered interval of the sample averages with n = 167 that are within 0.92 standard deviation s of the mean is of:
67.21 inches.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above(in case the score is positive) or below(in case the score is negative) the mean. From the z-score table, the p-value associated with the z-score is found, which represents the percentile of the measure X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].Considering samples of 167, with the mean and standard deviation of the population given in the problem, the parameters are given as follows:
[tex]\mu = 66.9, \sigma = 4.33, n = 167, s = \frac{4.33}{\sqrt{167}} = 0.335[/tex]
The desired height is X when Z = 0.92, because it is 0.92 standard deviations from the mean and we want the upper limit, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
0.92 = (X - 66.9)/0.335
X - 66.9 = 0.92 x 0.335
X = 67.21 inches.

(-1, 2), slope = 2 slope intercept form
Answer:
Slope-intercept form is given as y = mx + c where m is the slope and c is the y-intercept.
Since slope = 2, equation is y = 2x + c.
Substitute (-1,2) into the equation to find c.
2 = 2(-1) + c
c = 4
Hence, equation is y = 2x + 4

a) quotient = 23 and remainder = 14
b) quotient = 28 and remainder = 12.
c) quotient = 20 and remainder = 10.
a) Here in the first question we have to divide 405 by 17.
405 is not completely divisible by 17.
So when we divide 405 by 17 we get 23 as quotient and 14 as remainder.
we can cross check this by the formula;
Dividend= Divisor × Quotient + Remainder.
So in here the dividend is 405 and the divisor is 17 which when multiplied by the quotient 23 and added by the remainder that is 14 gives us 405.
Thus quotient = 23 and remainder = 14
b) Here dividend = 656 and divisor = 23
Thus when we divide 656 by 23 we get:
we get quotient as 28 and remainder as 12.
c) Given dividend is 1990 and divisor is 98.
Thus we divide 1990 by 98 we get:
Quotient = 20 and remainder = 10.

Y-intercept 9 and slop -2
The equation of the line that has the given features is y = -1/3x - 4
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the equation of the line?From the question, the given parameters are
Slope, m = -2
y-intercept, c = 9
As a general rule:
A linear equation is represented as
y = slope * x + y-intercept
This can be rewritten as
y = mx + c
Next, we substitute the known values in the above equation
So, we have the following equation
y = -2x + 9
The above equation cannot be further simplified
So, we have
y = -2x + 9
However, it can also be expressed as
y = 9 - 2x
Hence. the linear equation is y = -1/3x - 4

t(3) = -8.
How to evaluate the composition of functions?Here we have the two functions g(x) and f(x), and the composition:
