Answer:

Median without outlier should be 40

For the bottom questions, it should go:

Decreases the mean, does not change the median, does not change the mode

It's decreasing the mean because it goes from 44.7 to 39

Median w/ and without outlier is both 40

Mode also stays the same w/ or without the outlier, which is 96

Answer:

30ft

Step-by-step explanation:

Given data

Volume= 360 ft^3

Area= 12 ft^2

We know that the expression for volume is

Volume= Area*Height

Substitute

360= 12*h

h= 360/12

h= 30 ft

Hence the height of the prism is 30ft

Q3 = 63

Step-by-step explanation:

From the plot attached :

Data obtained is :

Temperature frequency

59 0

60 2

61 3

62 3

63 4

64 2

65 1

Frequency Total 15

Data in raw format :

60,60,61,61,61,62,62,62,63,63,63,63,64,64,65

The first quartile :

Q1 = 1/4(n+1)th term

n = 15

Q1 = 1/4(15+1)th term

Q1 = 1/4 * 16th

Q1 = 4th term

Q1 = 61

Third quartile (Q3):

Q3 = 3/4(n+1)th term

n = 15

Q3 = 3/4(15+1)th term

Q3 = 3/4 * 16th

Q3 = (48/4)th term

Q3 = 12th term

Q3 = 63

Answer:

Q1 is 61 and Q3=63

Answer:

The shortest possible perimeter is: [tex]4\sqrt{15}[/tex]

Step-by-step explanation:

Given

[tex]A = 15[/tex] --- area

Required

Find the shortest possible perimeter

Area is calculated as:

[tex]A=l * b[/tex]

This gives:

[tex]l * b = 15[/tex]

Make l the subject

[tex]l=\frac{15}{b}[/tex]

Perimeter is calculated as:

[tex]P =2(l + b)[/tex]

Substitute [tex]l=\frac{15}{b}[/tex]

[tex]P =2(\frac{15}{b} + b})[/tex]

Rewrite as:

[tex]P =2(15b^{-1} + b)[/tex]

Differentiate and minimize;

[tex]P' =2(-15b^{-2} + 1)[/tex]

Minimize by equating P' to 0

[tex]2(-15b^{-2} + 1) = 0[/tex]

Divide through by 2

[tex]-15b^{-2} + 1 = 0[/tex]

[tex]-15b^{-2} = -1[/tex]

Divide through by -1

[tex]15b^{-2} = 1[/tex]

Rewrite as:

[tex]\frac{15}{b^2} = 1[/tex]

Solve for b^2

[tex]b^2 = \frac{15}{1}[/tex]

[tex]b^2 = 15[/tex]

Solve for b

[tex]b = \sqrt{15[/tex]

Recall that: [tex]P =2(\frac{15}{b} + b})[/tex]

[tex]P = 2 * (\frac{15}{\sqrt{15}} + \sqrt{15})[/tex]

[tex]P = 2 * (\sqrt{15} + \sqrt{15})[/tex]

[tex]P = 2 * (2\sqrt{15})[/tex]

[tex]P = 4\sqrt{15}[/tex]

The shortest possible perimeter is: [tex]4\sqrt{15}[/tex]

Answer:

Question 4 is False

Question 5 is True

im doing this problem right now---

ok so a1=256 a2=64 a3=15 a4=4... find a9

the sequence divides by 1/4 every term

an=a1*r^n-1

an=(256)*(1/4)^n-1

replace n with 9

A9=(256)*(1/4)^9-1

A9=(256)*(1/4)^8

=(256)*(1/4)

A9=64^8

1/256 or a9= 0.00390625

Answer:

the midpoint is (4,3)

Step-by-step explanation:

-x + 2y = 6

x=− 6+2y

4y - 2x = 11

4y-2(-6+2y)=11

4y+12-4y=11

12=11

no solution

Answer:

Option A

Step-by-step explanation:

The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.

So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.

Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:

[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]

The end result matches with the equation determined before, so option A is the answer.  

Answer:

slope:  [tex]\frac{1}{2}[/tex]

y-intercept: (0,-3)  

Step-by-step explanation:

First, place the equation in slope-intercept form to identify the slope and y-intercept easily. Isolate the y in the equation to do this:

[tex]4y = 2x-12\\\frac{4}{4} y = \frac{2}{4} x-\frac{12}{4} \\y = \frac{1}{2} x-3[/tex]

Now that the equation is in slope-intercept form, it is much easier to find the slope and y-intercept of the equation. Remember that the slope-intercept formula is [tex]y = mx + b[/tex].

In an equation written in slope-intercept form, the [tex]m[/tex], or the coefficient of the x-term, represents the slope. So, the slope of his equation is [tex]\frac{1}{2}[/tex]. Also, the [tex]b[/tex], or the constant on the right side of the equation, represents the y-intercept. So, the y-intercept of this equation is (0,-3).  

Answer:

A or b

Step-by-step explanation:

Answer:

-48 b

Step-by-step explanation:

Answer:

The equation is ;

4x - y = 13

Step-by-step explanation:

The general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from what we are given, let us write the second equation in the general form

x + 4y = 10

4y = -x + 20

y = -1/4x + 20/4

y = -1/4x + 5

mathematically, when two lines are perpendicular, the product of their slope is -1

So for the second line with slope m2

m2 * -1/4 = -1

m2 = 4

So, using the general form, we have the equation as;

y = 4x + b

To get the value of b, we substitute the coordinates of the given point (3,-1)

-1 = 4(3) + b

-1 = 12 + b

b = -1-12

b = -13

So the equation is;

y = 4x - 13 which can be rewritten as;

4x-y = 13

Answer:

Y-intercept is (0,8)

Step-by-step explanation:

Firstly, we need to get the equation of the line segment

We have the general equation as;

y = mx + b

m is the slope and b is the y-intercept

So for the slope between (9,6) and (-2,-1); we have

m = (y2-y1)/(x2-x1)

m = (-1-6)/(-2-9) = -7/-11 = 7/11

Mathematically, when two lines are perpendicular, their slopes have a product of -1

Let the slope of the second line be m

m * 7/11 = -1

7m = -11

m = -11/7

The equation of the second line is;

y = mx + b

y = -11x/7 + b

The line passes through the point (3.5,2.5)

So,

2.5 = -11/7(3.5) + b

2.5 = -5.5 + b

b = 2.5 + 5.5

b = 8

so the y-intercept of the perpendicular bisector is 8

Answer:

4π

Step-by-step explanation:

Periodic graphs repeat the same pattern.  Here we have a cosine function which clearly repeats itself.  Start at (0, 1) and count the number of squares to the right before the graph looks the same; this occurs at (4π, 1).  x has increased from 0π to 4π.  Thus, the period is 4π.
