Answer:

deviation = -95.50147493     mean = 61

Step-by-step explanation:

54% wet there brushes first

suppose 68% wet there brushes what is the mean

mean: a mean is where you add both numbers together to get a total then divide by how many numbers you added for now we wont need the amount of people we just need the percentages for this

54 + 68 = 122

we added to numbers so well divide by 2

122 divided by 2 or 122/2 is equal to 61

61 is our mean

standard deviation : this is were you take the known average 1356 adults and subtract the mean

1356- 61 = 1295 then divide by 1356 and times by 100

if the number is positive then the mean is higher than expected but luckily its a negative so its -95.50147493

Answer:  this is in a fraction: X = 16/5, decimal form: x = 3.2, and in a mix number: x = 3 1/5

Step-by-step explanation:

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Step-by-step explanation:

Answer: Let length = 2x + 3

Let width = x

Area = 54 ft2

length × width = Area

x(2x + 3) = 54

2x2 + 3x = 54

2x2 + 3x - 54 = 0

(2x - 9)(x + 6) = 0

x = 9/2 and x = -6

x = 4.5 and x = -6

We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:

width = 4.5 ft

length = 2(4.5) + 3 = 9 + 3 = 12 ft

Answer:

=360x4+1440x3+24x+24

Step-by-step explanation:

6(x+4)(10)xx(6)x+(4)(6)x+24

=360x4+1440x3+(4)(6)x+24

=360x4+1440x3+24x+24

The answer is

Step-by-step explanation:

In order to solve this problem we use ratio and proportion

From the question

He used 3.00 to buy 4 bagels

Then 4.50 will be

[tex] \frac{4.5 \times 4}{3} \\ = \frac{18}{3} [/tex]

We have the final answer as

Hope this helps you

Let's assume the number as x

→ ⅔rd of x =( ⅔)x

Now ⅔ of x is greater than ⅓ of 5 .

[tex] \sf{ \implies \: \dfrac{1}{3} \times 5 = \dfrac{5}{3} } [/tex]

[tex]\sf{ \implies \: \dfrac{2}{3} \times x > \dfrac{5}{3} } [/tex]

[tex]\sf{ \implies \: x > \dfrac{5}{3} \times \dfrac{3}{2} }[/tex]

[tex]\sf{ \implies \: x > \dfrac{5}{2} }[/tex]

So number will be greater than 5/2 .

Answer:

8, 2, 8, 2

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

Answer:

9, 1, 9, 1

2, 8, 2, 8

3, 7, 3, 7

6, 4, 6, 4

Step-by-step explanation:

you would have to have the numbers repeat so it works, for instance, you could do 9,1,9,1 as the first row then 2,8,2,8 as the second row and for the third row you could do 3,7,3,7 and for the fourth row you could do 6,4,6,4 so both the columns and rows add to 20

Answer:

y = 10

Step-by-step explanation:

4/5 y = 8

4/5 y * 5/4 = 8 * 5/4           multiply by reciprocal

y = 10

Answer: y=10

Step-by-step explanation:

times each side by 5 so you're left with 4y=40

divide wach by 4 and then you got the answer

Answer:

the thousandths equils 2

Step-by-step explanation:

yuh

Answer:

  9007 thousandths = 9.007

Step-by-step explanation:

A unit is 1000 thousandths, so 9 ones is 9000 thousandths.

You have ...

  0.002 + 9.005 = 9.007

  2 thousandths + 9 ones 5 thousandths = 9007 thousandths = 9.007

Answer:

8

Step-by-step:

12+12=24

40-24= 16

there is 16 inches of wood left

16/2=8

8 inches of wood for each side of width.

Answer:

6 ft is the greatest length

Step-by-step explanation:

1 meter= 3.2 ft

1 meter= 100 centimeters

1 meter= 39.4 inches

6-3.2 = 2.8 which runs over

2/5 x 100 years = 40 years.

Answer:

Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.

The vertex of a parabola is the point at the top or bottom of the parabola.

'h' is -6, the first coordinate in the vertex.

'k' is -4, the second coordinate in the vertex.

'x' is -2, the first coordinate in the other point.

number of hours worked equation

The observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Observed amount:

At x = 7.9, y = $33.50

At x = 25.00, y = $25.00

We have a line of best fit:

y=0.3x+24.00

At x = 7.9

Predicated amount:

y = $26.37

At x = 12.1

Predicated amount:

y = $27.63

Residual (when x = 7.9)  = $33.50 - $26.37 = $7.13

Residual (when x = 12.1) = $25.00 -  $27.63 = -$2.63

Thus, the observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.

#SPJ2

Answer:

D. 1,000 cm^3

Step-by-step explanation:

Surface area of a cube is calculated by multiplying the square value of the edge by 6 which is shown as 6 × a^2

6 × a^2 = 600

a^2 = 100

a = 10

The volume of a cube is calculated by multiplying edge with itself three times which is shown as a^3

10^3 = 1000

Answer:

D

Step-by-step explanation:

10×10 on each side of the cube= 100. 6 sides = 600.

10×10×10= 1000

Answer:

Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)

Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's

Line 2 and Line 3: Neither -- different slopes

Step-by-step explanation:

Lines are parallel if they have the same slope but different y-intercept.

Lines are perpendicular if the slopes are negative reciprocals.

Answer: 150% increase

Step-by-step explanation:

percent of increase: new/old × 100%-100%

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

new/this month: 20 puppies

old/last month: 8 puppies

 new/old×100%-100%
