What is the answer to this?

Answer:

the answer is 1.16 shirts

Step-by-step explanation:

the mean absolute deviation is found by finding the average of the difference between each data point and the mean of the data.

1st...find the mean of the data by adding all the numbers according to the data plotted and dividing the by the numbers listed; which in this case is 10

1 +2+ 2+ 3+ 3+ 3+ 4+ 4+ 5+ 6 = 3.3

mean is 3.3

then find the difference between the mean and each data point

Data Point =                       1      2     2      3     3       3      4      4     5      6

Difference from mean = 2.3    1.3   1.3  0.3  0.3   0.3   0.7    0.7   1.7   2.7

Find the average of these differences by adding the (differences from Mean) by 10

2.3  + 1.3  + 1.3  + 0.3  + 0.3  + 0.3  + 0.7  + 0.7 +  1.7 + 2.7

                                             10

the mean absolute deviations is 1.16 shirts

3.3 - 2 = 1.3

3.3 - 3 = 0.3

3.3 - 3 = 0.3

3.3 - 3 = 0.3

3.3 - 4 = 0.7

3.3 - 4 = 0.7

3.3 - 5 = 1.7

3.3 - 6 = 2.7

____________________________

1.3 · 2 = 2.6

0.3 · 3 = 0.9

0.7 · 2 = 1.4

So your mean absolute deviation would be 1.16 :)!

Answer:

A. 20

Step-by-step explanation:

Since they both reflect each other, you would set (3x)° equal to (x + 40)°. Then move -x to the other side of the equivalence symbol to get 40 = 2x. This is how x is defined. You immediately divide by 20 to get your result above.

Yes an equilateral triangle is a type or acute triangle.

Answer: yes

Step-by-step explanation: An acute triangle means that all of the angles of the triangle are less than 90 degrees.

Since a triangle has three angles which always add to 180 degrees

and an equilateral triangle must have all of the same angles, it's impossible

to have an equilateral triangle that measures anything other than 60°.

Answer:

the volume of the sphere will be 4 times the volume of the cone;

Step-by-step explanation:

The question is on volume comparison

Volume of a sphere=4/3 [tex]\pi[/tex]×r³

Volume of a cone= [tex]\pi[/tex]/3×r²h

where r is the radius and h is the height

Apply the condition

If r=h=1 unit

Then volume of sphere will be= 4/3 × [tex]\pi[/tex]×1³ = 4/3[tex]\pi[/tex]

And volume of the cone will be= [tex]\pi[/tex]/3 ×1²×1 =[tex]\pi[/tex]/3

We can see the volume of the sphere will be 4 times the volume of the cone;

4/3[tex]\pi[/tex] = 4×[tex]\pi[/tex]/3

The volume of the sphere is exactly twice the volume of the cone.

To establish the relationship between the volumes of a cone and a sphere when they have the same radius and height, we need to use the formulas for the volumes of these shapes.

Let's denote the radius of both the cone and the sphere as r  and the height of the cone (which is also the diameter of the sphere) as h .

The volume V  of a sphere is given by the formula:

[tex]\[ V_{\text{sphere}} = \frac{4}{3}\pi r^3 \][/tex]

The volume V  of a cone is given by the formula:

[tex]\[ V_{\text{cone}} = \frac{1}{3}\pi r^2 h \][/tex]

Since the height of the cone is the same as the diameter of the sphere, we have [tex]\( h = 2r \).[/tex]Substituting this into the volume formula for the cone gives us:

[tex]\[ V_{\text{cone}} = \frac{1}{3}\pi r^2 (2r) = \frac{2}{3}\pi r^3 \][/tex]

Now, we can compare the volumes of the two shapes:

[tex]\[ V_{\text{sphere}} = \frac{4}{3}\pi r^3 \] \[ V_{\text{cone}} = \frac{2}{3}\pi r^3 \][/tex]

Dividing the volume of the sphere by the volume of the cone, we get:

[tex]\[ \frac{V_{\text{sphere}}}{V_{\text{cone}}} = \frac{\frac{4}{3}\pi r^3}{\frac{2}{3}\pi r^3} = \frac{4}{2} = 2 \][/tex]

Therefore, the volume of the sphere is exactly twice the volume of the cone when they have the same radius and height.

A.)> 161 is the answer

Final answer:

The expression 5x (36+9) simplifies to 225 by first adding the numbers in the parentheses (36+9) to get 45, and then multiplying 5 by 45.

Explanation:

The expression 5x (36+9) represents the phrase 'five times the sum of thirty-six and nine.' To evaluate this expression, you first perform the operation inside the parentheses. In this case, you add 36 and 9, which equals 45. After simplifying the parentheses, the expression becomes 5x45. As the final step, you multiply 5 by 45, which equals 225. Therefore, the expression 5x (36+9) equals 225.

Answer:

P(green) = ⇒ 5/14

P(red) = ⇒ 2/14

P(green and red) = ⇒ 5/98

The probabilities are P(green) = [tex]\frac{5}{14}[/tex], P(red) = [tex]\frac{1}{7}[/tex] and P(green and red) = [tex]\frac{5}{98}[/tex].

The probability of an event is calculated as the number of favorable outcomes divided by the total number of outcomes.

In this case, Deepak is choosing two marbles one after the other with replacement, which means after drawing the first marble, he puts it back into the bag before drawing the second one.

Since these are independent events (drawing the first marble does not affect the probability of drawing the second), the probability of both events happening is the product of their individual probabilities.

So, the probability that Deepak will choose one green marble and then one red marble is [tex]\frac{5}{14} *\frac{1}{7} =\frac{5}{98}[/tex].

Complete Question:

A bag contains fourteen marbles. There are 4 purple marbles, 3 blue marbles, 5 green marbles, and 2 red marbles. Deepak randomly chooses two marbles from the bag, one at a time, and replaces the marble after each choice. What is the probability he will choose one green marble and then one red marble? Express the probabilities in fraction form.

To find the number of days it can be used for $170, we put C= 175 in the equation, we get

[tex]175 = 20 + 25x\\\\\Rightarrow\ 25x=170-20\\\\\Rightarrow\ 25x=150\\\\\Rightarrow\ x=\dfrac{150}{25}=6[/tex]

Hence, the required number of days = 6.

Answer:

area = (exact) 88pi ft^2 or (approximate) 276 ft^2

Step-by-step explanation:

The surface area of a cylinder is the sum of the areas of the bases, two circles, and the lateral area which is a rectangle.

Each base is a circle, and the two bases are congruent, so find the area of one base and multiply by 2.

The lateral area is a rectangle. You need to find the length and width of the rectangle. Think of a can of food with a label wrapped around. If you make a vertical cut from one base to the other, and you unwrap the label, you will see that the lateral surface of a cylinder is a rectangle that has the height of the cylinder as its length, and the circumference of the base are its width.

area of circle = pi *r^2

area of rectangle = length * width

length of rectangle: length = 2(pi)r

width of rectangle: width = height = h

total area of cylinder = area of bases + lateral area

total area of cylinder = 2 * pi *r^2 + 2(pi)r * h

total area of cylinder = 2 * pi * (2 ft)^2 + 2 * pi * 2 ft * 20 ft

total area of cylinder = 8pi ft^2 + 80pi ft^2

total area of cylinder = 88pi ft^2

The exact area is 88pi ft^2.

If you need an approximate area, then use 3.14 for pi.

area = 88 * 3.14 ft^2

area = 276 ft^2

D. is your repeating decimal.

Answer:

375 units

Step-by-step explanation:

"What will its maximum height be?"

The given equation, h(x) = -3x^2 + 30x + 300, is a quadratic with coefficients a = -3, b = 30 and c = 300.

The axis of symmetry of this parabola will go thru the max ht.  The equation of the axis of symmetry is

x = -b / (2a)

In this particular case, the axis of symm. is x = -(30) / (2·[-3]), or x = 5 time units.

The max height is thus h(5) = -3(5)^2 + 30(5) + 300 = 375 units.

The answer is:

The maximum height reached by the projectile is 375 units.

To know what's the maximum height that the projectile reaches, we need to use the information about the given quadratic equation (parabola) to calculate the y-coordinate of the vertex.

The vertex of a parabola is located at the lowest or highest point depending on if the parabola opens upwards or downwards.

We can calculate the vertex of a parabola using the following equation:

[tex]x_{vertex}=\frac{-b}{2a}[/tex]

Then, after calculating the x-coordinate of the vertex, we need to substitute the x-coordinate value into the equation of the parabola to find the y-coordinate value or the highest point of the parabola.

We are given the parabola:

[tex]h(x)=y=-3x^{2}+30x+300[/tex]

Where,

[tex]a=-3\\b=30\\c=300\\[/tex]

Now, calculating the vertex we have:

[tex]x_{vertex}=\frac{-b}{2a}[/tex]

[tex]x_{vertex}=\frac{-30}{2*(-3)}=5[/tex]

Then, calculating the y-coordinate value, we have:

[tex]y_{vertex}=-3x^{2}+30x+300[/tex]

[tex]y_{vertex}=-3*(5)^{2}+30*(5)+300[/tex]

[tex]y_{vertex}=-3*25+150+300[/tex]

[tex]y_{vertex}=-75+150+300[/tex]

[tex]y=-75+150+300[/tex]

[tex]y_{vertex}=375[/tex]

Hence, the y-coordinate value of the vertex is equal to 375, meaning that the maximum height reached by the projectile is 375 units.

Answer: B

Step-by-step explanation:

the sum of any two sides is bigger than the third side... so 5+9= 14, bigger than 6. 5+6=11, greater than 9. 9+6=15, bigger than 5.

Answer:

B

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

So, let's test each of the points:

A) We have the points: 4, 8, 2. If we sum 4 and 2, the result is 6. Which is not greater than the third side which is 8. So it does not qualify for a triangle.

B) We have the points 5, 9, 6. If we sum 5+6 = 11 which is greater than 9. The sum of any two sides from this set is greater than the third side. It could create a triangle.

C) We have the points 6, 8, 16. If we sum  6+8 = 14 which is not greater than the third side 16. So it could not create a triangle.

D) we have the points 10, 4, 3. If we sum 4+3 = 7 which is not greater than 10. For that reason, it could not create a triangle.

To solve this problem, we find the side length of the square pool, find the inner perimeter of the sidewalk, and then calculate the difference between the outer and inner perimeters. The width of the sidewalk is 5 feet.

This is a Mathematics problem that involves some knowledge of geometry. Firstly, let's inspect the given information: The square swimming pool’s area is 225 square feet. Since the pool is square, the side length of the pool can be found by taking the square root of the area: √225 = 15 feet. So, the inside perimeter of the sidewalk is 60 feet (4*15).

However, the outside perimeter of the sidewalk is 80 feet. The difference between the outside and the inside perimeter (80 – 60) is 20. That value is twice the width of the sidewalk because the sidewalk extends around all four sides. Therefore, each side of the sidewalk must cover extra 5 feet (20 / 4). So, the width of the sidewalk is 5 feet.

[tex]a_n = 2.5 + 2.5n[/tex]

Step-by-step explanation:

Note that the sequence increases by a factor of 2.5, that is, each term is the sum of the previous term plus 2.5.

[tex]7.5 - 5 = 2.5\\\\10 -7.5 = 2.5\\\\12.5 -10 = 2.5[/tex]

therefore this is an arithmetic sequence with an increase factor d = 2.5

The linear formula for the sequence [tex]a_n[/tex] is:

[tex]a_n = a_1 + d(n-1)[/tex]

Where

[tex]d = 2.5\\\\a_1 = 5[/tex]

[tex]a_1[/tex] is the first term of the sequence

So

You have to get y by itself and to do that you need to do the opposite of order of operations.

So the opposite of subtraction is addition so you would add 37 to both sides.

It would cancel out itself then leave y by itself while the other side of the equation is 55

Answer: y = 55

Step-by-step explanation: You want to get the variable or y by itself, so you cancel out what number is next to it which is 37, so you add  -37 + 37 and that   cancels it out.The reason you add  them together is because of opposite operations since it was minus you want to add, and what ever you do to one side you have to do to the other, so 18 + 37 is 55 so y is 55

Answer:

(1, -10)

Step-by-step explanation:

Only the y can be on the left hand side. The square has been completed so all you need do is transfer the 10 to the right and read the x,y values for the vertex.

I have provided a graph to show you that the vertex and my answer are the same (hopefully).

y + 10 = 4(x - 1)^2          Subtract 10 from both sides.

y + 10-10=4(x -1)^2 -10  Combine

y = 4(x - 1)^2 - 10

Now we need to make the square term = 0

x - 1  = 0                        Add 1 to both sides

x - 1 + 1 = 0 +1               Combine

x = 1                              When x = 1 the square term will equal 0.

The vertex should be (1, - 10)

345*.06=20.7

The percentage of the sales tax Chan pay if Chan bought a $345 smartphone, but his total was $365.70 is 6%.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

Given:

The cost of smartphone = $345

The total amount = $365.7

Calculate the percentage as shown below,

Percentage of tax = The total amount - The cost of smartphone / The cost of smartphone × 100

Percentage of tax = (365.7 - 345) / 345 × 100

Percentage of tax = 20.7 / 345 × 100

Percentage of tax = 0.06 × 100

Percentage of tax = 6 %
