Answer:
discount rate= 0.35
Step-by-step explanation:
Giving the following information:
The price on the tag was $20, but Lauren paid $13 before tax.
To calculate the discount rate, we need to use the following formula:
Total discount= total price * ( 1 - discount rate)
13= 20 * (1 - discount rate)
13= 20 - 20discount rate
20discount rate = 7
discount rate= 7 / 20
discount rate= 0.35

jean:45%
a. realiza la distribucion de frecuencias y el diagrama circular
b. identifica la moda e interpretala de acuerdo con la situcacion
Answer:
la moda es el jean ya que es lo que mas se repite, osea lo que prefieren
de los datos podemos deducir que se encuestaron a 115 mujeres de las cuales el 17% prefiere dril, el 4% prefiere algodon, el 13% prefiere pana, el 26% prefiere tela y por ultimo el 39% prefiere el jean

On a day in the month of February the temperature in barrow Alaska is 221*f at the same time the temperature in northway Alaska is 213*f
Give the Full Question then I will solve it..
The volume of a gas was measured as
its temperature was increased from 10°K
to 15°K at intervals of 1°K. The volumes
were 1.5, 2.2, 3.38, 5.1, and 7.6 cm.
Would a linear or exponential function
better approximate the data described?
Explain why.

need help with questions 15 and 16 please
Answer:
#15: y = -5x -4
#16: y = 2/5x -4
Step-by-step explanation:
Lets start with #15:
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx -4
Pick another point and substitute its x and y values in this equation.
I chose (-1,1) and substituted as 1 = m(-1) -4
Isolate m:
1 + 4 = -m - 4 + 4
5 = -m
m = -5
The Equation in Slope Intercept Form is y = -5x -4
Let's do #16.
Slope-Intercept Form is y = mx + b, where m is the slope and b is the y-intercept.
First we can locate the y-intercept, or where the line passes through the y-axis.
The y-intercept is -4.
Substitute in the Slope-Intercept Form Equation:
y = mx - 4
Pick another point and substitute its x and y values in this equation.
I used Fractional Points as Whole ones were not seen.
I chose (5/2,-3) and substituted as -3 = m(5/2) - 4
Isolate m:
-3 + 4 = 5m/2 - 4 + 4
1= 5m/2
m=2/5
The Equation in Slope Intercept Form is y = 2/5x - 4

Find the value of x in the figure below
x =
degrees
x =
degrees
Answer:
x = 190 and x = 126
Step-by-step explanation:
In both diagrams the indicated angles are vertical and congruent, then
[tex]\frac{x}{2}[/tex] = 95 ( multiply both sides by 2 )
x = 190
and
x + 21 = 147 ( subtract 21 from both sides )
x = 126

B. 5 + 2i
C. 5i + 15
D. 13
E. 3
Answer: A
Step-by-step explanation:
Treat the real and imaginary parts separately, then combine. Because it is addition, not subtraction, distributing the sign will not make a difference. Remove the parenthesis and group like terms together. Then simplify and put in standard form for imaginary numbers (real first, then imaginary).

On the day of a child’s birth, a deposit of $25,000 is made in a trust fund that pays 8.75% interest, compounded continuously. Determine the balance in this account on the child’s 25th birthday.
9514 1404 393
Answer:
$222,822.57
Step-by-step explanation:
The account balance is given by ...
A = P·e^(rt)
where P is the principal invested at interest rate r for t years.
A = $25,000×e^(0.0875·25) ≈ $222,822.57
What is 2/5 y + 1/5 x -0.2y-6+(-2)
Answer:
[tex]\frac{y}{5} + \frac{x}{5}-8[/tex]
Step-by-step explanation:
1) Simplify 2 /5y to 2y/5.
[tex]\frac{2y}{5} + \frac{1}{5} x-0.2 y-6-2[/tex]
2) simplify 1/5x to x/5.
[tex]\frac{2y}{5} +\frac{x}{5} -0.2y-6-2[/tex]
3) Collect like terms.
[tex](\frac{2y}{5} -0.2y) + \frac{x}{5} +(-6-2)[/tex]
4) Simplify.
[tex]\frac{y}{5}+ \frac{x}{5} -8[/tex]
Therefor, the answer is y/5 + x/5 -8.

A driver travels 288 miles in 6 hours. What is the driver’s speed, in miles per hour? Is it 48? I got 48
Answer:
48
Step-by-step explanation:
288 divided by 6 is 48 and how you get mph is todal miles in 1 hr
The speed of the driver for the entire journey is 48 miles per hour.
The given parameters;
distance traveled by the driver, d = 288 milestime of motion, t = 6 hoursSpeed is defined as the ratio of total distance traveled by the total time of motion.
The speed of the driver for the entire journey is calculated as follows;
[tex]speed = \frac{distance}{time} \\\\speed = \frac{288 \ miles}{6 \ hours} \\\\speed = 48 \ miles \ per \ hour[/tex]
Thus, the speed of the driver for the entire journey is 48 miles per hour.

x-5=-y
3x-10=2y
Answer:
(4,1)
Step-by-step explanation:
Multiply the first equation by -3
(x-5=-y)*-3 = -3x+15=3y
Then combine like terms with the new equation and the second equation
(-3x+15=3y) + (3x-10=2y) = 5=5y
Divide 5 by both sides
1=y
Plug in 1 for y in an equation. Doesn’t matter which one and solve
x-5=-(1)
Distribute the negative sign to the 1
x-5=-1
Add 5 to both sides
x=4

Answer:
A = 588 in^2
Step-by-step explanation:
"a" is actually the sign for Pi, which is a set ratio of 3.14159.
The instructions say to use just 3 for Pi in this question though.
A = (3)14^2)
A = (3)(14)(14)
A = 588 in^2

Here is how to do the question,
The Remainder Theorem starts with an unnamed polynomial p(x), where "p(x)" just means "some polynomial p whose variable is x". ... If you get a remainder, you do the multiplication and then add the remainder back in. For instance, since 13 ÷ 5 = 2 R 3, then 13 = 5 × 2 + 3. This process works the same way with polynomials.
