By using the given information we can infer the domains of the function, and we will see that the piecewise function is:
c(x) = $15*x if 0 ≤ x ≤ 4
c(x) = $60 + 9*(x - 4) if x > 4.
How to get the piecewise function?
We know that the print charges $15 for each of the first four lines on an add, and $9 for each additional line.
Then we will have one piece for x between 0 and 4, and another piece for x larger than 4. The function will be:
c(x) = $15*x if 0 ≤ x ≤ 4
c(x) = $60 + 9*(x - 4) if x > 4.
Where the y-intercept on the second part is equal to the cost for the first four lines of the add.

Step-by-step explanation:
Number of Letters = 4
Number of Letters on the Alphabet = 26
Total Numbers used = 3
Total Range of Numbers = (0-9)
Since the first 4 characters are letters, the total number of combinations for each of them would equal to 26.
And for the following 3 numbers, the total number of combinations for each of them would equal to 10.
To find the answer, we multiply all the values:

It is estimated that 7 out
of 10 people invited to a
wedding will attend. If Mark
and Katie invite 120 people,
how many can they expect to
not attend?
Answer:
They can expect that 36 people will not attend.
Step-by-step explanation:
We are trying to figure out how many people didn't attend, so that would be 10 invites - 7 attendees = 3 bailers, so 3/10 people won't attend.
Now, you need to multiply that ratio to become 120 people:
3/10 --> x/120
In order to change that fraction, you must figure out what 120/10 is:
120/10 = 12
This means that the denominator was multiplied by 12, so the numerator must also be multiplied by 12 to get x:
3/10 --> (3*12)/120
--> 36/120
36 out of 120 people can be expected not to attend.

In-line skaters A study of injuries to in-line skaters used data from the National Electronic Injury Surveillance System, which collects data from a random sample of hospital emergency rooms. The researchers interviewed 161 people who came to emergency rooms with injuries from in-line skating. Wrist injuries (mostly fractures) were the most common.
The interviews found that 53 people were wearing wrist guards and 6 of these had wrist injuries. Of the 108 who did not wear wrist guards, 45 had wrist injuries. Why should we not use the large-sample confidence interval for these data?
a. Because 161 people are not enough for using the large-sample confidence interval.
b. Because the difference in sizes of the two groups is too large.
c. Because there are only 6 skaters in one group having wrist injuries.
d. Because the sample error is two large.
Using the Central Limit Theorem, it is found the correct option regarding why the large-sample confidence interval for these data.
c. Because there are only 6 skaters in one group having wrist injuries.
What does the Central Limit Theorem state?It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex], that is, as long as there are at least 10 successes and at least 10 failures in the sample.
In this problem, for the sample of people wearing wrist guards, only 6 had injuries, hence the large-sample confidence interval should not be used and option C is correct.

know?
Look at the left-most part of the blue diagram. It is 1 unit high. The corresponding left-most part of the red diagram is 2 units high, which is twice as high as the blue portion it corresponds to.
The scale factor tells us how to enlarge or shrink the object. In this case, the red figure is twice as tall and wide compared to the blue figure.
You can pick any pair of corresponding sides to get the scale factor.

Answer:
(11, 2 )
Step-by-step explanation:
3y + 2x = 28 → (1)
x = 5y + 1 → (2)
substitute x = 5y + 1 into (1)
3y + 2(5y + 1) = 28 ← distribute parenthesis on left side and simplify
3y + 10y + 2 = 28
13y + 2 = 28 ( subtract 2 from both sides )
13y = 26 ( divide both sides by 13 )
y = 2
substitute y = 2 into (2)
x = 5(2) + 1 = 10 + 1 = 11
solution is (11, 2 )

what is the amplitude and period of f(t) = sin2t
The equation [tex]f(t) = \sin(2t)[/tex] is an illustration of a sine function
The amplitude of the function is 1The period of the function is [tex]\pi[/tex]How to determine the amplitude?The equation of the sine function is given as:
[tex]f(t) = \sin(2t)[/tex]
A sine function is represented as:
[tex]f(t) = A\sin(B(t + C)) + D[/tex]
Where
A represents the amplitude
By comparison;
A = 1
Hence, the amplitude of the function is 1
How to determine the period?In (a), we have:
[tex]f(t) = A\sin(B(t + C)) + D[/tex]
Where the period is:
[tex]T = \frac {2\pi}B[/tex]

y2 -y1 -4-7 = -11
x1-x2 -8-5= -13
slope is 11/13
Answer:
y = [tex]\frac{11}{13}[/tex] x + [tex]\frac{36}{13}[/tex]
Step-by-step explanation:
First, find the slope of the line passing through the points
Then find the y-intercept of the line
Then construct the formula
1. find the slope
remember the formula
[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] is used to find the slope
now plug in the given points
(5, 7)
(-8, -4)
[tex]x_{1} = 5\\y_{1} = 7\\x_{2} = -8 \\y_{2} = -4[/tex]
[tex]\frac{(-4) - (7)}{(-8) - (5)}[/tex]
simplify and solve
= [tex]\frac{-11}{-13}[/tex]
= [tex]\frac{11}{13}[/tex]
2. find the y-intercept
remember the base formula for a line
y= mx + b
where m is the slope and b is the y-intercept
we know the slope, so now plug in one of the given coordinates for a point on the line and slove to find the y-intercept
y = mx + b
y = [tex]\frac{11}{13}[/tex]x + b
use the first set of given coordinates for a point on this line: (5, 7)
7 = [tex]\frac{11}{13}[/tex] * 5 + b
solve by inverse operations and simplifying
7 = [tex]\frac{55}{13}[/tex] + b
[tex]\frac{36}{13}[/tex] = b
3. construct the formula
now we know the slope and the y-intercept, all we have to do now is substitute it into the base formula for a line:
y = mx + b
where m is the slope and B is the y-intercept
we found that
m = [tex]\frac{11}{13}[/tex]
and
b = [tex]\frac{36}{13}[/tex]
so that means the equation is
y = [tex]\frac{11}{13}[/tex] * x + [tex]\frac{36}{13}[/tex]
A loan company charges $80 interest for a three-month loan of $550. Find the annual interest rate (APR) they are charging.
Answer:
Step-by-step explanation:
using the simple interst formula;
SI = Principal * Rtae * Time/100
Given
Principal = $550
SI = $80
Time = 3 month = 3/12 years
Required
Annual interest rate
Substitute
80 = 550 * R * 3/12*100
80 = 1650R/1200
96000 = 1650R
R = 1650/96000
R = 0.017
Rate = 0.017 * 100 = 1.7%

Solve for x.
3x + 2 = 38
Answer:
3x=38-2
3x=36
3x÷3=36÷3
x=12
Step-by-step explanation:
You start by grouping the like terms on one side, 2 is a constant number so you will group it with the constant 38. When you swap it to the other side of the equal sign, you change its sign. After you will divide both sides of the equation by the coefficient of x which is 3,in order to get the value of x.
