Hi There!
Step-by-step explanation:
Standard Deviation - tells you the avearage of how far apart each number in the set values is away from the mean.
Shop 1:
Mean = 46
Standard Deviation = 3
Shop 2:
Mean = 45
Standard Deviation = 19
I would choose shop 1 because even though it has a 1 more minutre of the mean it has a less of a standard deviation. That means that Shop 2 has a set of values that are far apart than shop 1.
Answer:
Shop 1

for how much you make after six hours
Answer:
Function: y= $4.25x + $50; After 6 hours: $25.50
Step-by-step explanation:
Answer:
Joe would make $75.50 after 6 hours.
Step-by-step explanation:
A function for this would be m = 50 + 4.25t. The $50 is the one time thing. We must multiply the tips by 6. 4.25 * 6 = 25.50. 50 + 25.50 is 75.50.
Simplify the given expression below (1+2i) times (5-3i)
Answer:
11 + 7i
Step-by-step explanation:
(1 + 2i)(5 - 3i)
= 1(5 - 3i) + 2i(5 - 3i)
= 5 - 3i + 10i - 6i^2
Note i^2 = -1 So we have:-
5 + 7i + 6
= 11 + 7i (answer).
The expression (1+2i) times (5-3i) simplifies to -1 + 7i by using the distributive property for multiplication over addition and remembering that i squared equals -1.
Explanation:The expression (1+2i) times (5-3i) is a function of two complex numbers. To simplify this, you would use the distributive property for multiplication over addition.
The first step is to distribute each component of the first number against each component of the second number. (1 * 5 + 2i * -3i) + (1 * -3i + 2i * 5)
Next, we perform the multiplications and simplify, bearing in mind that i squared is -1. This gives us (5 - 6) + (-3i + 10i)
So the simplified expression is -1 + 7i.

Write the equation of a line in slope intercept form that has a slope of 6 and has a y-intercept of ½.
Answer:
y=[tex]6x+ \frac{1}{2}[/tex]
Step-by-step explanation:
m=6
yint=1/2
y=mx+b
when x=0 y=1/2
1/2=6(0)+b
b=1/2
y=[tex]6x+ \frac{1}{2}[/tex]
The equation of the line in slope-intercept form is y = 6x + 1/2, where the slope is 6 and the y-intercept is 1/2. The slope of 6 means that for every increase of 1 in the x-axis, the y-axis will increase by 6.
Explanation:The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.
Given that the slope is 6 and the y-intercept is 1/2, the equation of the line is y = 6x + 1/2.
The slope of 6 means that for every increase of 1 in the x-axis, the y-axis will increase by 6.

The gas of your car is 40% full. There are 8 gallons of gas in a tank. What is the capacity of the gas tank?
Thanks in advance!
Step-by-step explanation:
Percentage by which the gas tank of the car is full = 40%
Amount of gas in the gas tank = 8 gallons
capacity of the gas tank = x gallons
40% * x = 8
(40/100) * x = 8
4x/10 = 8
4x = 8 * 10
4x = 80
x = 80/4
Answer = 20 gallons

The lengths of two consecutive sides are equal.
The slopes of two consecutive sides are not opposite reciprocals.
A) rectangle
B) square
C)rhombus
D) not enough info
Answer:
The correct option is C.
Step-by-step explanation:
The vertices of ABCD are A(2,-3), B(8,-6), C(14,-3), and D(8,0).
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The length of sides are
[tex]AB=\sqrt{(8-2)^2+(-6+3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
[tex]BC=\sqrt{(14-8)^2+(-3+6)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
[tex]CD=\sqrt{(8-14)^2+(0-3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
[tex]AD=\sqrt{(8-2)^2+(0+3)^2}=\sqrt{36+9}=\sqrt{45}[/tex]
Since length of all sides are equation therefore the given parallelogram cannot be a rectangle.
Slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of AB is
[tex]m_1=\frac{-6-(-3)}{8-2}=\frac{-3}{6}=\frac{-1}{2}[/tex]
Slope of BC is
[tex]m_2=\frac{-3-(-6)}{14-8}=\frac{3}{6}=\frac{1}{2}[/tex]
Since the slopes of two consecutive sides are not opposite reciprocals, therefore the given parallelogram is a rhombus. Option C is correct.
Simplify: 1 ( x − 5 ) − 1 3 ( − 3 x + 12 )
So since 1 multiplied by a number or variable, the number always stays the same we can say that 1(x-5)=x-5. We then, can open the parenthesis for 13*-3x+13*12. The answer for that would be -39x+156. So we then know that x-5-39x+156. We can simplify this until -38x+151.

A basketball is priced at $35.00. If it is on sale for 40% off, what is the final cost?
A basketball priced at $35.00 with a 40% discount would cost $21.00 after the discount.
Explanation:The final price of the basketball can be calculated by first identifying the amount being discounted from the original price. A 40% discount of a $35.00 basketball means you take 40% of 35. Here's how:
0.40 (40% converted to decimal) times $35.00 equals $14.00.
This $14.00 is the discount from the original price. Now, subtract this discount from the original price of the basketball to get the final price: $35.00 - $14.00 equals $21.00.
So, the final cost of the basketball after a 40% discount is $21.00.

Answer: There are 20 white lights.
Step-by-step explanation:
Given : There is a string of green and white lights strung around a mirror for every 6 green lights there are 4 white lights.
i.e. Ratio of green lights to white lights = 6:4
i.e.
[tex]\dfrac{\text{Number of green lights}}{\text{Number of white lights}}=\dfrac{6}{4}\\\\\Rightarrow\ \dfrac{30}{\text{Number of white lights}}=\dfrac{6}{4}\\\\\Rightarrow\ \text{Number of white lights}=\dfrac{4\times30}{6}=20[/tex]
Hence, there are 20 white lights.

Answer:
A
Step-by-step explanation:

sin 45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{5}[/tex]
multiply both sides by 5
note the exact value of sin 45° = [tex]\frac{\sqrt{2} }{2}[/tex]

(–6, 4)
(8, –6)
(4, –6)
Final answer:
The solution to the system of equations is (-6, 8), found by substituting x = -6 into the first equation and simplifying to find the value of y.
Explanation:
The solution to the system of equations y= -1/3x+6 and x = -6 can be found by substituting the value of x from the second equation into the first equation. Here's how it's done:
Substitute x into the first equation: y = -1/3(-6) + 6.
Simplify the equation: y = 2 + 6.
Add the numbers to find the value of y: y = 8.
Therefore, the solution to the system of equations is the point (-6, 8).
