xAnswer:

-10   -8   -6   -4

Step-by-step explanation:

The numbers are  

first =x

second= x+2

third=x+4

4th= x+6

2(x + (x+4)) = 3(x+6)-20

4x+8 = 3x+18–20

4x-3x=18–20–8

x=-10

So the numbers are       -10,           -8,              -6,            -4

                                       first           2nd          3rd             4th

           Check:

         2( -10-6)  = 3(-4) -20

            2(-16) =  -12-20

-32 = -32

Answer:

C. The data are skewed to the left, so the median height is greater than the mean height.

Step-by-step explanation:

The answer is C because the mean is typically less than the median when the data is skewed left.

Answer:

D I think

Step-by-step explanation:

Hope this helps.

Answer:

Option C would be correct!

Step-by-step explanation:

Since,

For Option A 8(2r) would be 16r not 10r

For Option B 6r + 3 would be 6r + 3 not 9r

For Option C 9(3r - 4) would be 27r - 36, and that indeed is the answer

For Option D r + r + r + r + r would be 5r not r⁵

Hope this helps!

Answer:

you should find the perimeter using rectrangle formula

Step-by-step explanation:

perimeter of rectrangle-2 (l+B)

length=22cm breadth=20cm

perimeter=2 (22+20)

=2 X 42

=84

Answer:

9 cm

Step-by-step explanation:

Length = 72 / (4 x 2)

Length = 72 / 8

Length = 9 cm

Hope that helps! :)

Answer:

12 quarters

Step-by-step explanation:

number of quarters ---------x

number of dimes ------------y

therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1

              0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2

equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12

there are 12 quarters

Answer:

we can only answer your question

Step-by-step explanation:

Each digit can be 1 of 9 numbers.

Each letter can be 1 of 22 letters.

To find total combinations, Multiply each number of choices by each number of choices.

9 x 22 x 22 x 22 x 22 x 9 = 18,974,736 total combinations

Answer:

a. Mean

b. μ = μ₀

c. 11.5%

d. Yes

Step-by-step explanation:

The given parameters are;

The mean work week for engineers, μ₀ = 63 hours

The standard deviation, σ = 5 hours

The number of engineers in Kara's sample, n = 10 engineers

The responses given by the 10 engineers are;

70; 45; 55; 60; 65; 55; 55; 60; 50; 55

a. The given information which the newly hired is hoping to find out that it is not is the mean

b. The null hypothesis which is that the company claim is correct, is therefore;

Null hypothesis, H₀; μ = μ₀ = 63 hours

c. Kara's mean, [tex]\overline x[/tex] is found as follows;

[tex]\overline x[/tex] = (70 + 45 + 55 + 60 + 65 + 55 + 55 + 60 + 50 + 55)/10 = 57

[tex]\overline x[/tex] = 57 hours

The Z-score is therefore;

[tex]Z=\dfrac{\overline x-\mu }{\sigma }[/tex]

Z = (57 - 63)/5 = -1.2

From the Z-table, we have;

The p-value for P([tex]\overline x[/tex] ≤ 57) =  P(Z ≤ -1.2) = 0.11507

The probability as a percentage given to one decimal place, that the mean would be as low as Kara's mean, P([tex]\overline x[/tex] ≤ 57) = 11.5%

d. Given that the percent percentage chance (11.5%) that the mean could be as low as hers ([tex]\overline x[/tex] = 57 hours) is higher than 10%, she should accept the claim.

Answer:

4/11

Step-by-step explanation:

there are 4 green out of 11 total

Answer:

4/11 is the probability you will get a green marble

Step-by-step explanation:

First you must determine the denominator by adding 4 and 7 to make the total number of marbles

4 + 7 = 11.

Next, you have 4 green marbles so you make it 4/11

Lastly, have a great day!

Answer:

The annual interest rate is 6%

Step-by-step explanation:

Use the formula for simple interest:  i = prt.

Set i = prt equal to $30:  $30 = prt

Solve this for r:

         $30

r = -------------- = ($30) / ($500)  = 0.06

      $250(2)

The annual interest rate is 6%

Answer:

Hello! answer: 28

Step-by-step explanation:

This is a complementary angle! So it will add up to 90 degrees so all we have to do is 90 - 62 so 90 - 62 = 28 so 28 is our answer!

Answer: 3, 4, 6

Step-by-step explanation: equilateral triangle, square, regular hexagon

In a regular tessellation 3,4,6 sides can be tessellating regular

polygon.

A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.

First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.

A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.

A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

3 = 4·2-1 (after inserting the numbers for f(n) and n)

= 11 and then the cycle just continues :) hope this helped a little.

Answer:

8 and 5

Step-by-step explanation:

Let the number of feet added = x

(x + 6) ( x + 3) = 40               Remove the brackets

x^2 + 6x + 3x + 18 = 40        Combine like terms on the left

x^2 + 9x + 18 = 40                Subtract 18 from both sides

               -18    -18

x^2 + 9x = 22                        Subtract 22 from both sides

x^2 + 9x - 22 = 0

This quadratic factors

(x + 11)(x - 2)

x + 11 = 0

x = - 11 which makes not sense.

x - 2 = 0

x = 2

The answer is x = 2

Check

6+2 = 8

3+2 = 5

Step-by-step explanation:

This is all about the symbols and how they are pronounced; it's also about what they mean in less formal language.

h is less than 21:  h < 21

h is greater than or equal to 21:  [tex]h \ge 21[/tex]  (notice the half-an-equal sign under the greater than sign)

h is less than or equal to 21:  [tex]h \le 21[/tex]
