Answer:

C is Perpendicular to A

Step-by-step explanation:

Answer:

(1) 330

(2) 692

(3) 110

(4) 43.25

Step-by-step explanation:

The data provided is for the dying time of four different types of paint.

One-way ANOVA can be used to determine whether all the four paints have the same drying time.

Use Excel to perform the one-way ANOVA.

Go to Data → Data Analysis → Anova: Single Factor

A dialog box will open.

Select the data.

Select "Grouping" as Columns.

Press OK.

The output is attached below.

The required values are as follows:

(1)

Sum of Squares of Treatment (Between Subjects):

SST = 330

(2)

Sum of Squares of Error (Within Subjects):

SSE = 692

(3)

Mean Squares Treatment (Between Subjects):

MST = 110

(4)

Mean Squares Error (Within Subjects):

MSE = 43.25

Answer:

width= 4, length= 6

Step-by-step explanation:

use perimeter formula and substitute values

so formula becomes:

20= 2(x+2) + 2(x)

expand the brackets and that gives us

20= 2x+4 +2x

so

16=4x

x= 4

so width is x which is 4

and length is x+2 which is 6

Answer:

9.21

Step-by-step explanation:

I'm pretty sure you just add the two numbers as positive numbers :/

The required distance on the number line between the points -1.85 and 7.36 is 9.21.

Given that,
To determine the distance between the two numbers on a number line points are -1.85 and 7.36.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
On the number line, -1.85 lies on the left of the zero, and 7.36 lies on the right so the required distance would be the addition of the two points. So,
Distance = 7.36 - (-1.85)
Distance = 7.36 + 1.86
Distance = 9.21

Thus, the required distance on the number line between the points -1.85 and 7.36 is 9.21.

Answer: x ~34.31 (rounded)

Answer:

a=30 ,  b=60,  c=105

Step-by-step explanation:

a=30 [Being vertically opposite angle]

Now,

      a+b+90=180 [Being the sum of interior angles of a triangle]

or, 30+b+90=180

or, b+120=180

or, b=180-120

so, b= 60

Again,

     c+75= 180 [Being linear pair]

or, c=180-75

so, c= 105

Step-by-step explanation:

Answer:

I gave the answers to the first four problems.

Step-by-step explanation:

1) LAB=40°

2) angle 3= 57°

3) x=25°

4) y= 29°

Answer:

Step-by-step explanation:

You equal both angles to each other and solve. You should get x=5, the you plug in x giving you 44 for both angles and 88 for ABC

If you need the answer in fraction form, then it would be 77/5

This is equivalent to the mixed number 15 & 2/5

======================================================

Work Shown:

y = k*x ..... general direct proportion equation

44 = k*240 .... plug in x = 240 and y = 44

240k = 44

k = 44/240

k = 11/60 .... divide both parts by 4

y = k*x   .... go back to the general form

y = (11/60)x .... plug in the k value we found earlier

y = (11/60)*84 .... plug in x = 84

y = 15.4

---------------

Extra info:

15.4 = 15 + 0.4

15.4 = 15 + 4/10

15.4 = 15 + 2/5

15.4 = 15 & 2/5 .... mixed number form

and

15.4 = 15 + 2/5

15.4 = 75/5 + 2/5

15.4 = (75+2)/5

15.4 = 77/5 ... improper fraction

Answer:

Step-by-step explanation:

Given the function  f(x) = 2x^2 + 5x + 3 with the domain {-1, 0, 3}, to get the mapping that best represents the function, we will have to find the codomain of the function given by substituting the domain values into the function;

when x = -1

f(-1) = 2(-1)^2 + 5(-1)+ 3

f(-1) = 2 - 5+ 3

f(-1) = 0

when x = 0

f(0) = 2(0)^2 + 5(0)+ 3

f(0) = 0+0+ 3

f(0) = 3

when x = 3

f(3) = 2(3)^2 + 5(3)+ 3

f(3) = 18+15+ 3

f(3) = 36

Hence the mapping is {0,3,16}

Answer:

A) Not a function

B) Function

C) Function

D) Not a function

Step-by-step explanation:

If the relation has two of the same x-values (that equal different y-values), it is not a function. In other words, if each input value leads to only one output value, classify the relation as a function.

{(-4,3), (-2,-1), (-4,8)}  = Not a function

{-4, 3), (-2.-1), (-7, 8)}  = Function

{-4,-2,-7, 7} = Function (I think?)

{-4,3). (-2, -1). (-2, -8), (-7,8)}= Not a function

Answer:

12.25 or 12 1/4

Step-by-step explanation:

Every day, the bird at 1.75 or 1 and 3/4. so, this would also equal to 1.75*1 day.

So, 7 days, the bird would eat, 1.75*7 days.

1.75*7=12.25

Answer:

12.25 or 12 1/4

Step-by-step explanation:

Every day, the bird at 1.75 or 1 and 3/4. so, this would also equal to 1.75*1 day.

So, 7 days, the bird would eat, 1.75*7 days.

1.75*7=12.25

Answer:

False

Step-by-step explanation:

To find the opposite of an integer, we just change its sign. If it is negative, change to positive. If it is positive change to negative. Opposite integers are the pairs of integers that have the same absolute value, or the same distance from zero. The sum of two opposites is always zero.

Answer:

5 1/3 miles

Step-by-step explanation:

We can use a ratio to solve

8 miles      x miles

------------ = --------

3 hours         2 hours

Using cross products

8*2 = 3x

16 = 3x

Divide by 3

16/3 = 3x/3

5 1/3 miles =x

Answer: [tex]5 \frac{1}{3}[/tex] miles

For the rate of 8 miles in 3 hours, you divide.

For the rate of - miles in 2 hours, multiply.

8 x 2 = 3x

16 = 3x

Now, we have to divide by 3x by 3.

3x divided by 3 = 5 1/3

Answer = 5 1/3

Answer:

  y = 3x +4

Step-by-step explanation:

In slope-intercept form, the equation of a line is ...

  y = mx + b

Where m is the slope (3) and b is the y-intercept (4).

Putting the given numbers in the equation, it becomes ...

  y = 3x +4

Answer:

-5/18

Step-by-step explanation:

-1 2/3 is equal to -5/3 and if you follow the keep change flip rule, keep -5/3 change the division sign to multiply and then flip the fraction (6/1 to 1/6) and then multiply.

-5/3 * 1/6 = -5/18

Answer:

Step-by-step explanation:

You want to get x on one side and the constants on the other. First subtract both sides by 3x to get:

-29 = 3x - 7

Now add 7 to both sides to get:

-22 = 3x

Divide each side by 3 to get:

x = -22/3

Answer:

Length: 25, Width: 7

Step-by-step explanation:

Let the width be represented by w. We can then assume that the length is equivalent to 3w+4

So, we can set the equation 2(3w+4)+2(w). Simplify to 8w+8=64

Simplify the equation and solve for w, which is 7

Plug into the the length, which is 3w+4

Answer:

Length: 25 inches

Width: 7 inches

Step-by-step explanation:

Perimeter = 2L + 2W

Length: 3w + 4

Width: w

64 = 2(3w + 4) + 2w

64 = 6w + 8 + 2w

64 = 8w + 8

56 = 8w

w = 7

Length: 3(7) + 4 = 25

Width: 7
