You start at (-5, -2). You move up 7 units and right 5 units. Where do you end?

Answer:

A

Step-by-step explanation:

The answer is the first one. We've used that in previous questions.

B is wrong. It needs to be equal to something (180 in this case). B is also saying that the first angle is = to the sum of the other two. Not so.

C is wrong. the third angle's x term has to be plus.

D has the same problem.

Answer:

Standard deviation decreases and mean increases

Step-by-step explanation:

The test scores are:

42, 72, 74, 78, 80, 80, 85, 88, 92

Mean = (42 + 72 + 74 + 78 + 80 + 80 + 85 + 88 + 92)/9 = 76.77

Median is 5th term which is 80

Range is highest score - lowest score = 92 - 42 = 50

Standard deviation from an online calculator gives 13.69

Now,we want to know what happens to those values when the outlier is removed. The outlier in this case is 42 because it is not consistent with other scores which range from 72 - 92.

Thus,the new set of scores are;

72, 74, 78, 80, 80, 85, 88, 92

New Mean = (72 + 74 + 78 + 80 + 80 + 85 + 88 + 92)/8 = 81.125

New Median will be the average of the 4th and 5th term which is (80 + 80)/2 = 80

New Range = 92 - 72 = 20

New Standard deviation from an online calculator gives 6.39

From the comparison above when the outlier is removed, we can say that;

- Mean increases

- remains the same

- Range decreases

- standard deviation decreases

Please check the explanation.

Step-by-step explanation:

Given the set W = {x, y, z}

If there are n elements in a set, then are 2ⁿ subsets.

As there are 3 elements in a set, then are 2³ or 8 subsets.

so

W = {x, y, z} has 8 subsets.

They are:

∅, {x}, {y}, {x}, {x, y}, {x, z}, {y, z}, and {x, y, z}

Step-by-step explanation:

Pounds of food : number of guinea pigs

1 pound : 5 guinea pigs

8 pounds : x guinea pigs

Where,

x = number of guinea pigs at 8 pounds of food

Inequality:

1 : 5 ≤ 8 : x

1/5 ≤ 8/x

Answer:

773 or 278.5 (if it only wants the sides the pic shows)

Step-by-step explanation:

13*5=65

65/2=32.5 (since it is a triangle you by 2)

12*9=108

108/2=54

15*20=300 (it is a square so you leave it)

you do it on the other sides that you can't see in the pic.

Add all the numbers together: 32.5+32.5+54+54+300+300 or 32.5(2)+56(2)+300(2)=773

Answer:

Formula : V = I (1 + R)^T  , Deers after 5 years ≈  556

Step-by-step explanation:

Exponential formula for  final value 'v' - for initial value 'i' at growth rate 'r' for a period of time 't'

V = I (1 + R)^T

As per given deer case, I = 330 & R = 11% = 0.11

V = 330 ( 1 + 0.11 )^t

Predicted deers after 5 years, V = 330 (1.11)^5

330 x 1.685 = 556.05

Answer:

168

Step-by-step explanation:

16.8 = 10%

x = 100%

To get to 100%, you have to multiply 10 by ten and 16.8 by 10. Like this:

16.8 = 10%                   original equation

16.8 (10) = 10% (10)      * both sides by 10

168 = 100%                  simplify

Answer:

Step-by-step explanation:

16.8 is 10% of 168

Answer: (2,2)

Step-by-step explanation:

I'm going to use substitution to solve this:

First, I use the second equation to solve for y in terms of x.

2x - y = 2

-y = 2 - 2x

y = 2x - 2

Then, I plug the value for y into the first equation:

2x + 4y = 12

2x + 4(2x - 2) = 12

2x + 8x - 8 = 12

10x - 8 = 12

10x = 20

x = 2

Now that we have x, we can plug it into either equation (I used the first) to get the value for y:

2x + 4y = 12

2(2) + 4y = 12

4 + 4y = 12

4y = 8

y = 2

We get the point (2,2) as a solution.

Note: This is the point where both lines intersect.

After solving the equation, the value of for the points x and y are (2, 2).

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given equation in the question,

2x + 4y = 12   (i) and

2x - y = 2  (ii)

Solve the value for y,

5y = 10

y = 10/5

y = 2

Substitute y=2 in equation (i)

2x + 4(2) = 12

2x = 12 - 8

x = 4/2

x = 2

Therefore, the point is (2, 2).

Answer:

C) 18 square units

Step-by-step explanation:

There are many ways to go about solving this.  You could divide it into two triangles with a middle section.  But it might be easier just to count the squares:

whole squares = 12

half squares = 4 (which equals 2)

3/4 square = 4

1/4 squares = 4

(add the 3/4 and 1/4 squares to equal 4)

12+2+4=18
