Answer:

A.

Step-by-step explanation:

The interquartile range for republicans is 185.5. The interquartile range for democrats is 186.5.

367.5 - 181 = 186.5

356 - 170.5 = 185.5

Answer:

A

Step-by-step explanation:

Answer:

The total weight is 80g, this is equal to the weight of the salt in the mixture plus the weight of the water in the mixture.

Ws = Weight of the salt

Ww = Weight of the water.

Then:

Ww + Ws = 80g

and the solution is 35% salt, so we have:

Ws/80g = 0.35

We must solve the system of equations, we can write the second equation as:

Ws = 80g*0.35 = 28g

Then we have 28 grams of salt, and the other 62g must be of water.

Step-by-step explanation:

Let x represent the weight of the salt

Let y represent the weight of the water

We know x + y = 80g total

If the salt solution is 35%, we can write the following equation:

x/80g = 0.35

x = 80g x 0.35 = 28

28 grams

Answer:

Option D.

Step-by-step explanation:

It is given that triangle XYZ has vertices X(–1, –3), Y(0, 0), and Z(1, –3).

Malik rotated the triangle 90° clockwise about the origin. So, rule of rotation is

[tex](x,y)\to (y,-x)[/tex]

Now,

[tex]X(-1,-3)\to X'(-3,-(-1))=X'(-3,1)[/tex]

[tex]Y(0,0)\to Y'(0,0)[/tex]

[tex]Z(1,-3)\to Z'(-3,-(1))=Z'(-3,-1)[/tex]

The image points are X’(–3, 1), Y’(0, 0), Z’(–3, –1).

Therefore, the correct option is D.

Answer:

the answer is X'(-3,1),Y'(0,0),Z'(-3,-1)

Answer:

[tex]\frac{1}{10}[/tex]

Step-by-step explanation:

[tex]4-\frac{11}{3}=\frac{4*3}{1*3}-\frac{11}{3}\\\\=\frac{12}{3}-\frac{11}{3}\\\\=\frac{12-11}{3}\\\\=\frac{1}{3}\\\\\\4-\frac{2}{3}=\frac{4*3}{1*3}-\frac{2}{3}\\\\=\frac{12}{3}-\frac{2}{3}\\\\=\frac{12-2}{3}\\\\=\frac{10}{3}[/tex]

[4 - 11/3] ÷ (4 - 2/3) = [1/3] ÷ (10/3)

                              [tex]=\frac{1}{3}*\frac{3}{10}\\\\=\frac{1}{10}[/tex]

Answer:

First, we have to find slope. We do that by using slope formula. Once we have found slope, we have start to write our equation in slope-intercept form. To get the complete equation, we need to find the y-intercept. To do so, we simply plug in one of the coordinates given to us into our half-formed equation. We should be able to find the y-intercept and then have our complete linear equation once we write it all out.

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

270 degree counterclockwise rotation around the origin

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

Check out the diagram below. In the diagram, I only focus on points A and A'.

We have A = (-3,4) move to A ' = (4, 3). We see the x and y coordinates swap places. Then the new second coordinate -3 becomes positive, or it has flipped sign. So the rule applied here is [tex](x,y) \to (y,-x)[/tex] which describes a 90 degree clockwise rotation; which is equivalent to a 270 degree counterclockwise rotation

The other points follow the same idea.

Answer:

Thus, area of triangle is [tex]225/\sqrt{3}[/tex]

Step-by-step explanation:

Area if triangle is given by 1/2( base*height)

Given

Height = 15 units

also one angle is given as 30 degrees

we know Tan of any angle is  ratio of perpendicular and base

[tex]tan\alpha = perpendicular /base[/tex]

lets calculate tan 30 in the given triangle

we will take the smaller triangle containing angle 30 degrees and right angle

perpendicular will be half of base of triangle

base will be side with length 15 units

tan30 = perpendicular/15

[tex]1/\sqrt{3} = perpendicular/15\\=> perpendicular = 15/\sqrt{3}[/tex]

Thus, half of base of full triangle is [tex]15/\sqrt{3}[/tex]

so full base will be [tex]15*2/\sqrt{3} = 30/\sqrt{3}[/tex]

Full full triangle

height = 15 units

base =  [tex]15*2/\sqrt{3} = 30/\sqrt{3}[/tex]

Thus, area of triangle is [tex]1/2* 30/\sqrt{3}*15= 225/\sqrt{3}[/tex]

Step-by-step explanation:

As someone has thankfully answered your question. I'll just try to explain that concept to you.

In direct proportion, as the first variable increases or decreases, the second variable also increases or decreases. In mathematical statements, it can be expressed as y = kx. This reads as “y varies directly as x” or “y is directly proportional as x” where k is constant in the equation.

So yes the answer is D

Answer:

The third option

Step-by-step explanation:

first, you can eliminate the 2nd and the 4th option because the vertex of the graph is located at -3, and not 3. The reason it is not the 1st option is, because  of the greater than or equal to sign, this inequality actually shows the white area.

Therefore, leaving the 3rd option. The y-intercept is correct, it is -3. The sign is also correct, because on the axis of the quadratic, -3 is the highest possible y-intercept. So y has to be less than or equal to -3.

Hope this helps! :D

Answer: KINDLY CHECK EXPLANATION

Step-by-step explanation:

Given the data:

1) dataset:

My data(x) : 2, 4, 6, 8, 10

2) to calculate the mean absolute deviation of the data above :

Step 1: Find the mean (m) of the dataset (my data)

Mean(m) = sum of values in my data / number of observations in my data (n)

m = (2+4+6+8+10) / 5

m = 30 / 5 = 6

The mean absolute deviation(MAD) :

Sum of The absolute value of the difference between values in my data and the mean value (m) Divided by the number of observations.

MAD = (Sum of |x - m|) / n

MAD = (|2-6| + |4-6| + |6-6| + |8-6| + |10-6|) / 5

MAD = (4 + 2 + 0 + 2 + 4) / 5

MAD = 12 / 5

MAD = 2.4

Answer:

Neither perpendicular nor parallel.

Step-by-step explanation:

To find the answer, you just need to find the slopes of each line.

The slope of the line with points at (-6, 5) and (-2, 7) would be (7 - 5) / (-2 + 6) = 2 / 4 = 1/2.

The slope of the line with points at (4, 2) and (6, 6) would be (6 - 2) / (6 - 4) = 4 / 2 = 2.

They are most definitely not the same line.

They are not perpendicular, either, since although they are [eek I forgot the term for it] opposites, they are both positive. To be perpendicular, one slope must be negative and the other positive.

They are not parallel, since the slopes are not the same.

So, the relationship between the lines are that they are neither parallel nor perpendicular.

Answer:

24,950.

Step-by-step explanation:

You can use the arithmetic series formula (a sequence is the list of numbers; a series is the summation of the list).

To find the sum...

(100 / 2) (2 * 2 + (100 - 1)5) = 50 * (4 + 99 * 5) = 50 * (4 + 495) = 50 * 499 = 24950.

Hope this helps!

Answer:

The sum of the first 100 terms of the arithmetic sequence is 24,950.

Step-by-step explanation:

Sn (sum of the first n terms of an AP) is given by n/2(2a + (n-1)d)

Where

n is the number of terms

a is the first term

d is the common difference

S100 = 100/2(2×2 + (100-1)5) = 50(4 + 99×5) = 50(4 + 495) = 50(499) = 24,950

**plug it in using the Pythagorean Theorem**

6^2+8^2= 10^2

36+64=100

100=100 (true)

Answer:

True

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

We can prove that it is a right triangle by using the Pythagorean Theorem. We have the hypotenuse as 10 and our legs as 8 and 6:

8² + 6² = 10²

64 + 36 = 100

100 = 100

So, 6-8-10 is a Pythagorean Triple.

So, the expression becomes

[tex]9^{-2} = \frac{1}{9^2}[/tex]

Expand the denominator

[tex]9^{-2} = \frac{1}{9 * 9}[/tex]

[tex]9^{-2} = \frac{1}{81}[/tex]

Hence, [tex]9^{x}[/tex] is [tex]\frac{1}{81}[/tex] when x = 2

Answer:

72

Length=12

Width=6

Answer:

72cm²

Step-by-step explanation:

perimeter= 2(l+w)

         36  = 2(l+w)

       36/2 = l+w

           18 = l+w

since, l is twice as w

18= 2w + w

18 = 3w    (we can add since all the variables, and exponents are same)

18/3 = w

6= w

NOW,

 w=6  and l is equal to twice as 6

so l=12

area= l×b

        = 12×6 = 72cm²
