The median, mode and range of the numbers are 9, 5 and 7 respectively.

The median is the middle number when the data is arranged in ascending order.

Therefore,

7, 7, 7, 8, 10, 11, 12, 12

median = 8 + 10 / 2 = 18 / 2 = 9

median = 9

The range is the largest number minus the smallest number.

Therefore,

range = 12 - 7 = 5

range = 5

The mode is the number that appears most. Therefore,

mode = 7

Answer:

KM = 7

LM = 7

KL = 11

Step-by-step explanation:

Isosceles triangles have 2 congruent sides (in this case they are KM and LM

This means 4d-13 = 12-d

We can now solve for d

4d-13 = 12-d | add d to both sides

5d-13 = 12 | add 13 to both sides

5d = 25 | divide both sides by 5

d = 5

Now we can solve for the 3 sides of triangle KLM

KM = 7

LM = 7

KL = 11

Step-by-step explanation:

Answer:

b = -4, 0

Step-by-step explanation:

Given :

Take b as a common factor.

Solutions

Answer:

b = - 4, b = 0

Step-by-step explanation:

b² + 4b = 0 ← factor out b from each term

b(b + 4) = 0

equate each factor to zero and solve for b

b = 0

b + 4 = 0 ⇒ b = - 4

Answer:

y=4x-20

Explanation:

Since we already have a slope, all we need to do is just find the y-intercept. To do this we can make an XY t-chart.

Using the chart we can see that for every x that decreases, a y decreases 4 times. So if we subtract 5 from x, we will multiply 5 times y. Note that this graph is increasing so the y-intercept is negative. -5 · 4 = -20

   X  |  Y

   6  |  4

   5  |  0  

   0  |  -20

[tex]\frac{2.52}{0.12}[/tex] = [tex]\frac{0.12n}{0.12}[/tex]

The limits of the domain and the range are 0 to 200, respectively; and you would use the minimum and maximum values of the domain and range because the graph of the inequality uses a solid line.

The items selected here could be any of the listed drinks and food items.

To solve this question, we use the following selection:

In this case, we use the less than or equal to inequality.

So, we have:

0.5x + 0.5y ≤ 100

In (b), we have:

0.5x + 0.5y ≤ 100

Subtract 0.5x from both sides

0.5y ≤ -0.5x + 100

Divide through by 0.5

y ≤ -x + 200

This means that the slope is -1, and it means that for every food item bought, there is a decrement of 1 in the drink.

See attachment for the graph of the inequality

The features of the graph include

From the attached graph, we have:

This means that you can buy 200 food items, when you buy no drinks or buy 200 drinks when you buy no food item

These are the acceptable x and y values of the graph.

From the attached graph, we have:

The domain and range are different from the domain and range of any linear equation because the domain and the range of a linear equation is the set of all real numbers, while this domain and range are limited to 0 to 200

Answer:

Step-by-step explanation:

Formula

d = speed * time

d = s * t

Givens

t = 1 hour

t2 = 3 hours

s = 5 miles / hour

Solution

t = 1 hour

d = s * t

d = 5 mph * 1 hour

d = 5 miles

t = 3 hours

d = s * t

d = 5 miles / hour * 3 hours

d = 15 miles

Answer

d = s * t

d = 5 miles

d = 15 miles

Answer:

G.31

Step-by-step explanation:

when n = 31

1116n = 1116*31 = 34596

34596 is square of 186.

= 186^2

= 34596

and other values (24,28,33) of n does not give square during 1,116n but 31 gives.

Hence, 31 is the possible value of n for which 1,116n is the square of an integer(186).

The number of whole revolutions for 1000 meters is 265, while the time taken to move 1000 meters with a speed of 40rev/min is 7minutes.

This is the number of times a body moves round  a circular path.

A revolution is equal to the circumference of a circle.

Analysis:

r  = 120/2 = 60cm

1 revolution of a circle = 2πr

Let n be the number of revolutions

so that 2πr x n = 1000 x 100 since 100 cm = 1 m

n = 100000/2πr = 265 revolutions

If the Fan turns 40 rev / minute

Then it 265 revolutions = 1000 meters, 265/40 = 7 minutes

In conclusion, the number of revolutions for 1000 meters is 265 and the time taken for 265 revolutions is 7 minutes.

Answer:

correct option is A i.e. 8/3

Answer:

∠G = 53°

∠H = 90°

∠I = 37°

Step-by-step explanation:  

∠H = 90°  because it is a right angle and all right angles = 90°

The sum of all angles in a triangle = 180°

∠H + ∠G + ∠I = 180°

90° + (5x - 7)° + (3x + 1)° = 180°

5x - 7 + 3x + 1 = 90°                         Subtract 90° from both sides

8x - 6 = 90                                       Adding like terms

8x = 96                                            Adding 6 to both sides

 x = 12                                             Dividing both sides by 8

Now solve for ∠G and ∠I using 12 as the value for x

∠G = (5x - 7)°                 ∠I = (3x + 1)°

∠G = 5·12 - 7                  ∠I = 3·12 + 1

∠G = 53°                         ∠I = 37°

The longest line segment that can be drawn in a right rectangular prism that is 14cm long, 13cm wide and 11cm tall is 19.1cm.

A right rectangular prism is a three dimensional solid shape formed by 6 rectangles.

it is also called the cuboid.

Analysis:

The diagonal of the face of the prism with dimensions 14cm long and 13cm wide is the longest line segment that can be drawn.

Since rectangles have 90° on each vertex, we can use Pythagoras theorem to calculate for the length of the diagonal.

[tex](diagonal)^{2}[/tex] = [tex](length)^{2}[/tex] + [tex](width)^{2}[/tex]

[tex](diagonal)^{2}[/tex] = [tex](14)^{2}[/tex] + [tex](13)^{2}[/tex]

                 = 196 + 169 = 365

 [tex](diagonal)^{2}[/tex] = 365

diagonal = [tex]\sqrt{365}[/tex] = 19.1cm

In conclusion, the length of the longest diameter is 19.1cm
