Step-by-step explanation:
Ling and her family ordered takeout that cost $50. Ling paid 4% sales tax and left a 10% tip
Answer:
$47
Step-by-step explanation:
Given data
Cost= $50
Tax= 4%
Tip= 10%
Let us find the amount of the Tax
=4/100*50
=0.04*50
=$2
Let us find the amount of the Tip
=10/100*50
=0.1*50
=$5
Hence the total amount is
=50+2-5
=52-5
=$47
The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day:
A box plot is shown. The left-most point on the plot is 20 and the right-most point is 95. The box is labeled 40 on the left edge and 60 on the right edge. A vertical line is drawn inside the rectangle at the point 50.
Part A: List two pieces of information that are provided by the graph and one piece of information that is not provided by the graph. (4 points)
Part B: Calculate the interquartile range of the data, and explain in a sentence or two what it represents. (4 points)
Part C: Explain what affect, if any, there will be if an outlier is present. (2 points)
PART A: Two pieces of information that are included by the graph are the minimum value (20) and the maximum value (95). One piece of information that is not included in the graph is the number of students who surf the internet. (this one doesn't really need a step by step because it is just analyzing a graph)
PART B: The IQR is equal to 20. The IQR represents the mid-spread, or 50% of the data.
Step-By-Step:
To find the IQR, you need to subtract the first quartile from the third quartile. So to find the IQR we would need to subtract 60 (Q3) and 40 (Q1),
60-40 = 20
= 20.
20 is the IQR
PART C: If an outlier is present, it may affect the mean, but will not change the median or the mode.
Step-By-Step: An outlier is an abnormally large (or small) number in a given data set.
Best of luck,
Some 6th grader.

sketch the graphs of y= sin x, y= sin 2x, and y=2 sin x. describe how the graphs are alike and how they are different
Answer:
Step-by-step explanation:
The graphs can be seen in the picture attached below where
y= sin x is the red wave
y= sin 2x is the blue wave
y=2 sin x is the green wave
Each graph is obviously a wave in shape but where they all differentiate is in the frequency and amplitude of the wave. Meaning how often a wave cycle repeats in the functional and how high and low the wave cycles actually get. That is where the difference takes place sinx has wider wave cycles than the other two. sin2x has the shortest wave cycles, almost twice for everyone red wave cycle. While 2sinx has the highest and lowest amplitude of all of the waves.

The r-value of the given data is 0.374.
What is a correlation coefficient?The correlation coefficient, denoted as r, is a statistical measure that describes the strength and direction of the linear relationship between two variables.
It ranges between -1 and +1, where -1 indicates a perfect negative correlation (inverse relationship), +1 indicates a perfect positive correlation (direct relationship), and 0 indicates no correlation between the variables.
We have,
First, we need to find the correlation coefficient (r) of the given data.
We can use the following formula to do this:
r = [n∑(xy) - (∑x)(∑y)] / [√{n∑x² - (∑x)²} √{n∑y² - (∑y)²}]
where n is the number of data points, x, and y are the respective variables, and ∑ denotes the sum of the values.
Using the given data, we can calculate the values as follows:
n = 5
∑x = 39
∑y = 53
∑(xy) = 442
∑x^2 = 483
∑y^2 = 1249
Substituting these values into the formula, we get:
r = [5(442) - (39)(53)] / [√{5(483) - (39)^2} √{5(1249) - (53)²}]
r = [2210 - 2067] / [√(2415) √(5660)]
r = 143 / (61.898 75.245)
r = 0.374 (rounded to three decimal places)
Therefore,
The r-value of the given data is 0.374.

what is the measure of angle KIT?
Answer:
80°
Step-by-step explanation:
In rhombus, opposite angles are equal. i.e <KET = <KIT
Triangle KET is isoceles, which means both parts of angle E are equal.
Angle E = 40 + 40
Angle E = 80
If angle E is 80 than Angle I is also 80.
find the area of a circle if its circumference is 10 pi
Answer:
25π
Step-by-step explanation:
pi's symbol is π, which will be used sometimes to make it easier later
The circumference is equal to diameter multiplied by pi. (Diameter is the length across the circle, radius the center of the circle to an edge point aka. half the diameter, and circumference is the edge length aka. perimeter of the circle.)
We can then remove the pi off the 10, as the diameter multiplied by pi is the circumference, so the diameter is 10.
Half of 10 is 5, the radius.
The formula for area of a circle is radius squared times pi, remember easily by π r ^2
We can plug in the radius into the formula to get
π 5 ^2
And finish it by solving the square root to get
π 25
25π

Admission to the carnival is $10 plus $2 per ride. John spent $38 on admission and
rides. Write and solve an equation to find how many rides John went on.
Answer:
he went on 14 rides.
Step-by-step explanation:
take your total, 38, subtract that by 10 (because you have to pay the admission fee) and you have 28 dollars spent on rides. each ride costs 2 dollars so divide 28 by 2 and you get 14.
The Eagle Ridge Contractors Association claims the average price of a home in their subdivision is $125,150 with a standard deviation of $7,350. A sample of 36 homes for sale in this subdivision had an average selling price of $123,550. The Eagle Ridge Home Owners Association is interested in knowing if the costs of homes for sale in this subdivision are actually lower than claimed? Compute the test value.
Answer:
The test value is z = -1.31.
Step-by-step explanation:
The Eagle Ridge Contractors Association claims the average price of a home in their subdivision is $125,150.
This means that the null hypothesis is that the mean is this value, that is:
[tex]H_0: \mu = 125150[/tex]
The Eagle Ridge Home Owners Association is interested in knowing if the costs of homes for sale in this subdivision are actually lower than claimed.
This means that at the alternate hypotehsis we test that the mean is lower than that value, that is:
[tex]H_a: \mu < 125150[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
125150 is tested at the null hypothesis:
This means that [tex]\mu = 125150[/tex]
Standard deviation of $7,350.
This means that [tex]\sigma = 7350[/tex]
A sample of 36 homes for sale in this subdivision had an average selling price of $123,550.
This means that [tex]n = 36, X = 123550[/tex]
Compute the test value.
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{123550 - 125150}{\frac{7350}{\sqrt{36}}}[/tex]
[tex]z = -1.31[/tex]
The test value is z = -1.31.

Find an equation of joint variation. Then solve for the missing value.
a varies jointly as b and c.
One set of values is a = 2.4, b = 0.6, and c = 0.8.
Find a when b = 0.4 and c = 0.4.
a = 0.8
a = 1.2
a = 0.032
a = 1.6
Click on the correct answer
Answer:
a = 0.8
Step-by-step explanation:
a varies jointly as b and c.
This means that a can be written as a constant k multiplied by b multiplied by c, that is:
[tex]a = kbc[/tex]
One set of values is a = 2.4, b = 0.6, and c = 0.8.
We use this to find the value of k:
[tex]2.4 = k(0.8)(0.6)[/tex]
[tex]0.48k = 2.4[/tex]
[tex]k = \frac{2.4}{0.48}[/tex]
[tex]k = 5[/tex]
So
[tex]a = 5bc[/tex]
Find a when b = 0.4 and c = 0.4.
[tex]a = 5bc = 5(0.4)(0.4) = 5(0.16) = 0.80[/tex]
The answer is a = 0.8.

Find the value of x
Answer:
x=135
Step-by-step explanation:
The two angles are supplementary, meaning they both add up to 180°.
So to find the value of one angle, simply subtract 50 from 180.
180-50=130
So now we know that 130 is equal to the expression.
x-5=130
Add 5 to both sides.
x=135

through: (3,0), parallel to y = 2/3x+1
Answer:
y = 2/3x - 2
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 2/3x + 1. Its slope is 2/3. A line parallel to this one will also have a slope of 2/3.
Plug this value (2/3) into your standard point-slope equation of y = mx + b.
y = 2/3x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (3, 0). Plug in the x and y values into the x and y of the standard equation.
0 = 2/3(3) + b
To find b, multiply the slope and the input of x (3)
0 = 2 + b
Now, subtract 2 from both sides to isolate b.
-2 = b
Plug this into your standard equation.
y = 2/3x - 2
This equation is parallel to your given equation (y = 2/3x + 1) and contains point (3, 0)
Hope this helps!
