Answer:

First option at second row , Option( C )

Step-by-step explanation:

In order to solve the problem,

First we need to arrange the numbers in ascending order.

4 , 7 , 8 , 10 , 11 , 13 , 15 , 15 , 22 , 28

Median = [tex]\frac{11 + 13}{2}[/tex]

             = 12

From the first range ( 4,7,8,10,11 ) , we can find Q1 also known as first quartile where Q1 = 8 ( middle-most number).

Similarly, from the second range ( 13,15,15,22,28 ) , we can find Q2 also known as third quartile where Q3 = 15 (middle-most number ).

Now, for the box plot,

We need to draw a number line from 0 to 32.

Next, we need to draw a box from Q1 to Q3 with a vertical line through the median.

Next, we put dots above 4 and 28 since our numbers start from 4 and end with 28.

Finally we join the dots and the box plot with a straight line.

Hence, option C is the correct choice.

Answer:

Rule + 30, Equation: w=d+30

Step-by-step explanation:

Hope this will help some of you!

The amount in dollar for w weeks be d= 30 x w.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Let w = the number of weeks.

Let d = the number of dollars April pays the service.

April pays a dog-walking service $30 each week to walk her dog.

So, the equation represents the situation

d= 30 x w

Hence, the amount in dollar for w weeks be d= 30 x w.

Answer:

A) 1/5

Step-by-step explanation:

There are 25 candies total, and you want to choose the 5 orange candies there.

That's 5/25.

Simplifying, we divide both sides by 5.

Thus, we get:

1/5.

Explanation:

The linear equation f(x) = x-1 has the y intercept -1. We can see this by comparing it to y = mx+b and see that b = -1. Or we could plug in x = 0 to get the output y = -1.

The graph shows the y intercept is y = 3. The jump from y = -1 to y = 3 is plus 4. This means the graph of f(x) has been moved up 4 units. Therefore, k = 4.

Since y = f(x), saying g(x) = f(x)+k = f(x)+4 means we add 4 onto each y value. This indicates every point on the f(x) line moves up 4 units to arrive at a corresponding point on the g(x) line.

Answer:

The function is increasing on the intervals (-∞, -1) and (2, ∞)

The function is decreasing on the intervals (-1, 2)

The domain of the function is (-∞, ∞)

Step-by-step explanation:

In order to see where the function is decreasing or increasing, check the x values to see where it is the rise and where it is fall.  The domain of the function is never-ending so it is (-∞, ∞)

Answer:

1/19/72

Step-by-step explanation:

Answer:

D. t = 5

when the object is at rest => x(t) = 0

<=> -t^2 + 4t + 5 = 0

<=> t^2 - 4t - 5 = 0

<=> (t - 5)(t + 1) = 0

=> t = 5 or t = -1

but t》0

=> t = 5

The value of t if the object at rest is 2 secs: Option A is correct

Given the position of the object moving in a straight line expressed as:

x(t)=5+4t−t²

The velocity of the body at rest is zero

Get the velocity fucntion.

v(t) = d(x(t))/dt = 4 - 2t

Since v(t) = 0

0 = 4 - 2t

-4 = -2t

t = 2

Hence the value of t if the object at rest is 2 secs

Decimal Representation

The model is shown in the figure. It has a form of a cube where each face is divided into 10 equal squares, forming a 10x10x10=1,000 smaller cubes piece.

Out of that 1,000 cubes, only 11 are shaded. This leaves us to think the decimal represented by the model is the division between the shaded cubes by the total cubes, thus:

[tex]number= \frac{11}{1,000}[/tex]

Answer:

Step-by-step explanation:

B

Answer:

x = 48° and y = 70°

Step-by-step explanation:

As it is an isosceles triangle so base angles of isosceles triangle are equal

x +7° = 55°

x = 55° - 7°

Therefore x = 48°

Now

x + 7 = (48 + 7)°= 55°

Calculating the value of y as sum of angles of triangle is equal to 180°

y + 55° + 55° = 180°

y + 110° = 180°

y = 180° - 110°

Y = 70°

Hope it will help :)

Answer:

x=48

y=70

Step-by-step explanation:

Key skills required are triangles, isosceles triangles, one variable equations, interior angle sums

1) You have to start with the fact that the triangle is isosceles. This means that the 2 base angles (x+7 and 55) are equal to each other.

An isosceles triangle has 2 sides equal and 2 angles equal.

2) With the explanation above --> x+7=55

3) Subtract 7 from both sides and you will get x=48

4) The sum of all the angles in a triangle is 180 degrees. The two bottom angles are 55 degrees each, making their sum 55+ 55= 110 degrees.

5) 110 degrees + y degrees = 180

6) subtract 110 from both sides and y would equal 70.

Answer:

$96.74

Step-by-step explanation:

The original cost of the Amazon echo = $99.99

Then we have a 10% sale which we are going to subtract from the original cost.

= $99.99-(99.99x10%)

= 99.99-9.999

= $89.991

Then a tax of 7.5% was added

= $89.991 + (89.991 x 7.5%)

= 89.991 + 6.749325

= $96.740325

Therefore the cost of the echo including tax is $96.74
