when outliers are removed, how does the mean change?​

Answer:

7y

Step-by-step explanation:

The answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is,

combine y and 7

Now a variable is a symbol (usually a letter) that stands for a value that may vary.

Here y is our variable.

When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions, the resulting combination of mathematical symbols is called a mathematical expression.

Thus, combining y and 7 may have result as-

7a, 7 +y, 7 - y and 7/y.

Thus, the answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.

Answer:

Runner 1 = 9th place

Runner 2 = 10th place

Runner 3 = 11th place

Runner 4 = 12th place

Runner 5 = 13th place

Step-by-step explanation:

Given that:

Number of runners = 5

Total points scored = 55

Finishing spot for each runner (they finished one after the other)

Hence,

x, (x + 1), (x + 2), (x + 3), (x + 4)

x + x + 1 + x + 2 + x + 3 + x + 4 = 55

5x + 10 = 55

5x = 55 - 10

5x = 45

x = 9

Hence,

Runner 1 = 9th place

Runner 2 = 10th place

Runner 3 = 11th place

Runner 4 = 12th place

Runner 5 = 13th place

Answer:

16

Step-by-step explanation:

let the smaller no be x so the greater no is 8 + x

soln

8+x + x = 40

8 + 2x = 40

2x = 40-8

2x = 32

x = 32÷2

therefore x = 16

Answer:

16 and 24

Step-by-step explanation:

let the 2 numbers be x and y, x > y , then

x + y = 40 → (1)

x = y + 8 → (2) [ greater number 8 more than smaller ]

Substitute x = y + 8 into (1)

y + 8 + y = 40, that is

2y + 8 = 40 ( subtract 8 from both sides )

2y = 32 ( divide both sides by 2 )

y = 16

Substitute y = 16 into (2)

x = 16 + 8 = 24

The 2 numbers are 16 and 24

Answer:

A. 27 degrees, 63 degrees, 90 degrees.

Step-by-step explanation:

Let the angle of the triangle be x

Given the following data;

3 : 7 : 10 = 3x : 7x : 10x

We know that the sum of the sides of a triangle is equal to 180 degrees.

3x + 7x + 10x = 180

20x = 180

x = 180/20

x = 9

For the first side;

3x = 3 × 9 = 27°

For the second side;

7x = 7 × 9 = 63°

For the third side;

10x = 10 × 9 = 90°

Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.

Answer:

The measure of the angles of a triangle are in the extended ratio of 3 : 7 : 10. Find the measures of the angles.

A. 27 degrees, 63 degrees, 90 degrees✓

B. 30 degrees, 60 degrees, 90 degrees

C. 30 degrees, 70 degrees, 100 degrees

D.33 degrees, 77 degrees, 80 degrees

Step-by-step explanation:

Let the required angles of the triangle be 3x, 7x and 10x

According to the above problem,

[tex]3x + 7x + 10x = 180 \\ 20x = 180 \\ x = \frac{180}{20} \\ \boxed{x = 9}[/tex]

Therefore the angles are :---

[tex]3x = 3 \times 9 = 27°✓ \\ 7x = 7 \times 9 = 63°✓ \\ 10x = 10 \times 9 = 90°✓[/tex]

Answer: 17 years

Step-by-step explanation:

City A is currently 2,425 people in number and growing at 27 per year.

An expression to find the population in a given year assuming the year is x would be:

= 2,425 + 27 * x

= 2,425 + 27x

Applying the same logic to City B would give an expression of:

= 1,813 + 63x

Equating these together will give the year they will be the same:

2,425 + 27x = 1,813 + 63x

2,425 - 1,813 = 63x - 27x

612 = 36x

x = 612/36

x = 17 years

A parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

The coordinates of vertex C are (11, 3).

A parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

Three vertices of the parallelogram ABCD.

A = (0, 2)

B = (8, 1)

D = (3, 4)

C = (x, y)

        A___________B

         /                       /

       /          O          /

     /                       /

   D                     C

Now,

AO = OC

BO = DO

O is the midpoint of BD.

O =(m, n)

m = (8 + 3) / 2

m = 11/2

n = (1 + 4)/2

n = 5/2

O = (11/2, 5/2)

Now,

O is the midpoint of AC.

m = (x + 0)/2

11/2 = x/2

x = 11

n = (y + 2)/2

5/2 = (y + 2)/2

y + 2 = 5

y = 3

The coordinates of C.

= (x, y)

= (11, 3)

Thus,

The coordinates of vertex C are (11, 3).

Answer:

6.375 tons or 6 3/8 tons

Step-by-step explanation:

According to Given data, calculation are as follows,

Sunburst pebbles = 2 1/2 tons or 2.5 tons

Black polished pebble = 3 1/4 tons or 3.25 tons

River pebble = 5/8 tons or o.625 ton

So, total weight of pebbles are as follows,

Total weight = 2.5 tons + 3.25 tons + 0.625 ton

= 6.375 tons or 6 3/8 tons

Hence, total weight of pebbles was 6 3/8 tons.
