Harry's Electronics kept track of how many customers bought a newly released gaming system during the first month it was available. The following box plot was created from this data.
Which of the following properly describes the data?
The correct statement is
The data is skewed right.
What is Box and whisker plot?The lower and upper quartiles are shown on the left and right sides of a box and whisker plot, respectively. The interquartile range, which contains 50% of the data, is covered by the box. The median is the vertical line that divided the box in half.
We have a box and whisker plot.
Based on the position of the median value in the box plot, we may decide if a distribution is skewed or not. The distribution is right-skewed (or "positively" skewed") when the median is closer to the bottom of the box and the whisker is shorter on the lower end of the box.
A right-skewed distribution with a positive skewness is one in which the median is smaller than the mean. The median of a left-skewed distribution is bigger than the mean when the skewness is negative, on the other hand.
Here, the data is shorter on the lower end of the box.
Thus, the plot is positively skewed.

At the present time, Daniel is 8 years older than his cousin William. In two years' time, Daniel will be 3 times older than William is at the present time. How old is Daniel at the present time?
Answer:
Daniel is 10 years old presently
Step-by-step explanation:
Since we do not know the ages of both people, we assign variables.
Let Daniel’s present age be d while Willam’s present age is w
Daniel is 8 years older;
Mathematically;
d = w + 8 •••••••••••(i)
In two years time Daniel’s age will be d + 2 while William’s age will be w + 2
We know that Daniel will be 3 times as old as Williams will be in these two years time
Mathematically;
d + 2 = 3(w + 2) ••••••• (ii)
From equation 1, we have w = d-8
we substitute this into equation ii
d + 2 = 3(d-8+2)
d + 2 = 3(d-6)
d + 2 = 3d - 18
3d - d = 18 + 2
2d = 20
d = 20/2
d = 10 years
Geometry Question!!!
Answer:
EB = 20
Step-by-step explanation:
Given 2 chords intersecting inside a circle, then
Th product of the parts of one chord is equal to the product of the parts of the other chord, that is
10x = 8(x + 5) ← distribute
10x = 8x + 40 ( subtract 8x from both sides )
2x = 40 ( divide both sides by 2 ), thus
x = EB = 20
If a sample of 2.00 moles of NO gas was reacted with excess
oxygen, how many moles of nitrogen dioxide gas would be
produced?
Answer:
2 moles
Step-by-step explanation:
first you have to balance the equation:
2NO + O2⇒2NO2
then set up your mole to mole ratio
2 mol NO2/2 mol NO
multiply by the given 2.00 mol NO gas
and you should get 2 mol NO2
Final answer:
Starting with 2.00 moles of nitrogen monoxide (NO) and reacting it with excess oxygen (O2) will produce 2.00 moles of nitrogen dioxide (NO2) based on the 1:1 mole ratio from the balanced chemical equation.
Explanation:
The student is asking about the stoichiometry of a chemical reaction involving nitrogen monoxide (NO) and oxygen (O2) to produce nitrogen dioxide (NO2). In the balanced chemical equation, the reaction is typically represented as 2NO + O2
ightarrow 2NO2. Following the mole ratio from the balanced equation, 1 mole of NO reacts with 1/2 mole of O2 to produce 1 mole of NO2. Consequently, if you start with 2.00 moles of NO, you would also produce 2.00 moles of NO2 given that oxygen is in excess and will not limit the reaction.
This is because the balanced chemical equation shows the NO and NO2 in a 1:1 mole ratio. Therefore, the number of moles of reactants you start with will directly determine the number of moles of products formed, assuming you have an excess of the other reactants.

You have a tree in your yard 4 ft to the left of and 5 ft in front of the corner of your porch. A circular fence 3 ft in radius has its center at the tree. If the corner of your porch is the origin and forward is the positive y direction, what equation represents the circle formed by the fence in your yard?
Answer:
[tex](x+4)^2+(y-5)^2=9[/tex]
Step-by-step explanation:
If the corner of your porch is the origin
4 ft to the left, x=-45 ft in front, y=5The tree's location is at (-4,5).
A circular fence 3 ft in radius has its center at the tree(-4,5).We want to determine the equation of a circle with center (-4,5) and radius 3 ft.
The equation of a circle center (h,k) with a radius of r is given as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(h,k)=(-4,5), r=3
The equation formed by the fence therefore is:
[tex](x-(-4))^2+(y-5)^2=3^2\\\\$Simplifying we obtain:\\\\(x+4)^2+(y-5)^2=9[/tex]

Miss Quinn made 4 loaves of bread for a dinner party. She cut one loaf in half and put a piece in her freezer. She then divided the remaining full loaves of bread into sixths. Her guests ate 7 pieces. How much bread does Miss Quinn have left?
Answer:
2 5/6
Mrs Quinn has 2 full loaves of bread and 5 pieces of the 1/6 portions of the bread.
Step-by-step explanation:
Mrs Quinn had 4 loaves of bread
1 loaf was divided into two halves
1/2 was kept in the freezer
3 loaves was divided into 1/6 pieces
Step 1
How many 1/6 pieces can we find in 3 loaves?
1 loaf of bread = 6 pieces of 1/6 portions of bread
3 loaves of bread =
3× 6 pieces = 18 pieces of 1/6 portions of bread in total.
From the question, her guests ate 7 pieces
The number of pieces left = 18 - 7
= 11 pieces left.
Step 2
We are asked how many loaves of bread does Mrs Quinn have left?
This is calculated by adding up the 11 pieces of 1/6 portions of the bread with the first loaf of bread that she divided into 2
The total would be
= 1 loaf + 11 pieces of 1/6 sizes of bread
= 1 loaf + 11( 1/6)
= 1 + 11/ 6
= 1 + 1 5/6
= 2 5/6
Therefore Mrs Quinn has 2 full loaves of bread and 5 pieces of the 1/6 portions of the bread.
Final answer:
After dividing and serving bread at her dinner party, Miss Quinn has 11 pieces of bread plus the half loaf she initially put in her freezer left.
Explanation:
Miss Quinn made 4 loaves of bread for a dinner party. She cut one loaf in half and put a piece in her freezer. She then divided the remaining full loaves of bread into sixths. Her guests ate 7 pieces. How much bread does Miss Quinn have left?
First, let's figure out how many pieces of bread Miss Quinn had after cutting and dividing the loaves. She had 4 loaves of bread total. After cutting one loaf in half and storing one half, she was left with 3.5 loaves. She then divided the 3 full loaves into sixths, resulting in 18 pieces (3 loaves × 6 pieces), plus the half loaf she did not cut into sixths. Therefore, before the guests ate, Miss Quinn had 18 pieces + 1 half loaf (considered as 1 unit here), for a total of 19 units of bread.
Her guests ate 7 pieces of the bread divided into sixths, leaving Miss Quinn with 18 - 7 = 11 pieces of the sixths and the half loaf in the freezer. Therefore, Miss Quinn has 11 pieces of bread + 1 half loaf left after her guests have eaten.

a right triangle with an angle of approximately 53.1 is inscribed in the first quadrant of the unit circle with a horizontal length of 3/5 and a vertical length of 4/5 complete the table for the following trigonometric functions
In a right triangle with an angle of 53.1 degrees, and sides 3/5 and 4/5, the sine is 4/5, the cosine is 3/5, and the tangent is 4/3. aThese methods and results are a fundamental part of understanding trigonometric functions in Mathematics.
Explanation:In this scenario, you were given a right triangle inscribed in the first quadrant of the unit circle. The angle of the triangle is given as 53.1 degrees, the horizontal length (adjacent side) is 3/5, and the vertical length (opposite side) is 4/5. We can calculate the trigonometric functions based on this. Trigonometry revolves around the relationship between side lengths of triangles and the angles they form.
Sine (sin) of an angle is defined as the ratio of the length of the side that is opposite the angle to the length of the longest side of the triangle (hypotenuse). Here, sin(53.1) = Opposite/Hypotenuse = 4/5.
The Cosine (cos) of an angle is defined as the ratio of the length of the adjacent side of the angle to the hypotenuse. So, cos(53.1) = Adjacent/Hypotenuse = 3/5.
The Tangent (tan) of an angle is the ratio of the sine of the angle to the cosine of the angle, which also equals the ratio of the opposite side to the adjacent side. Tan(53.1) = Sin(53.1)/Cos(53.1) = (4/5) / (3/5) = 4/3.

The sine, cosine, and tangent of an angle in a right triangle inscribed in the first quadrant of the unit circle are respectively equal to the ratios of opposite/hypotenuse, adjacent/hypotenuse, and opposite/adjacent sides. So, in your case where the triangle has an angle of 53.1 degrees, horizontal length 3/5, and vertical length 4/5, sinθ = 4/5, cosθ = 3/5, and tanθ = 4/3.
Explanation:In the right triangle you mentioned, the hypotenuse is the radius of the unit circle which is 1, the horizontal length (adjacent side, often represented as x) is 3/5, and the vertical length (opposite side, often represented as y) is 4/5. The quoted angle, usually symbolized as θ, is 53.1 degrees. With this information, we can calculate the trigonometric functions as follows:
Sine (sin) of θ is defined as the ratio of the opposite side to the hypotenuse. So, sinθ = y/h = 4/5 Cosine (cos) of θ is the ratio of the adjacent side to the hypotenuse. So, cosθ = x/h = 3/5 Tangent (tan) of θ is the ratio of the opposite side to the adjacent side. So, tanθ = y/x = (4/5) / (3/5) = 4/3 Learn more about Trigonometric Functions here:
