Answer:

Mean : ≈ 12.7

Median: ≈ 13.5

Step-by-step explanation:

To find the mean you must add all the numbers and divide by the # of numbers in the set.

8+12+13+14+14+15 = 76

76/6 ≈ 12.7

To find the median you have to order the numbers from least to greatest, the middle number should be the median, but in this case two numbers are in the middle.

8, 12, 13, 14, 14, 15

So you have to add 14 and 13, which is 27.

Then divide by 2 which is ≈ 13.5

Answer:

294 m² is correct

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the height and a, b the parallel bases

here h = 21, a = 21 and b = 7, thus

A = [tex]\frac{1}{2}[/tex] × 21 × 28 = 294 m²

Answer:

3√2(5√8-7√3) = 60 - 21√6

Step-by-step explanation:

We need to find the product of  3√2(5√8-7√3). The distributive property states that: A(B+C) = AB + AC.

Then, by using the distributive propertive we have that:

3√2(5√8-7√3) = 3√2 * 5√8 - 3√2 * 7√3 = 15√8√2 - 21√2√3.

Also, we know that: √A√B = √AB. Using this:

15√8√2 - 21√2√3 = 15√16 - 21√6 = 60 - 21√6.

Answer:

The correct answer is 60 -21√6

Step-by-step explanation:

It is given that,

3√2(5√8 - 7√3)

To find the product

We have

3√2(5√8 - 7√3) = 3√2(5√8) -  3√2(7√3)

= 3*5√(2 * 8) - 3 * 7 √2 * 3

= 15√16 - 21√6

= 15 * 4 - 21√6

= 60 -21√6

Therefore 3√2(5√8 - 7√3) = 60 -21√6

The correct answer is 60 -21√6

The coat costs $194 while the suit costs $97

To find out how much the coat costs when a suit and a coat together cost $291 and the coat costs twice as much as the suit, we use algebra to deduce that the suit costs $97 and the coat costs $194.

To solve the problem of determining how much the coat costs when the total cost of a coat and a suit is $291, and the coat costs twice as much as the suit, we can set up a system of equations. Let's define s as the cost of the suit and c as the cost of the coat. Following the given information, we have two equations:

Substituting the second equation into the first one gives us:

s + 2s = $291

Combining like terms, we get:

3s = $291

Dividing both sides by 3 to solve for s, we find:

s = $97

Now that we have the cost of the suit, we can use the second equation to find the cost of the coat:

c = 2s = 2 times $97 = $194

Therefore, the coat costs $194.

Answer:

3.1623 (sqrt(10))

Step-by-step explanation:

Standard Deviation is calculated by first squaring the differences between the observations and the mean and then taking the square root of the sum of the squares of the differences divided by the number of observations - 1.

Mean = Sum of Observations/Total Observations

Mean = (5 + 7 + 9 + 11 + 13)/5 = 45/5 = 9.

Square of the mean = 9^2 = 81.

Now subtracting the mean from each observation and squaring it gives:

(5 - 9)^2 = (-4)^2 = 16

(7 - 9)^2 = (-2)^2 = 4

(9 - 9)^2 = (0)^2 = 0

(11 - 9)^2 = (2)^2 = 4

(13 - 9)^2 = (4)^2 = 16

Sum of squares = 16 + 4 + 0 + 4 + 16 = 40.

Standard deviation = sqrt(40/4) = sqrt(10) = 3.16 (correct to 2 decimal places).

Therefore, answer is 3.16!!!

ANSWER

The point (1,2) is not a solution

EXPLANATION

We could see that, the point (1,2) lies exactly on the boundary line.

Since the boundary line is dashed, the points on the boundary line are not solution.

Alternatively:

We deduce the inequality from the graph to be;

[tex]y < 3x - 1[/tex]

If the point (1,2) is a solution,then it must satisfy the inequality.

[tex]2 \: < \: 3(1) - 1[/tex]

[tex]2 \: < \: 2[/tex]

This statement is false.

Hence, the point (1,2) is not a solution.

Remark

When you join the midpoints of two sides of a triangle, two properties are true.

For this question, the first property is not as important as the second.

it means that DE is 1/2 the size of GJ

Equation

4x + 5 = 1/2 * (3x + 25)

Solution

Multiply both sides by 2

2(4x + 5) = 2*[1/2*(3x + 25)       Simplify

2(4x + 5) = 3x + 25                   Remove the brackets on the left

8x + 10 = 3x + 25                      Subtract 3x from both sides

8x-3x + 10 = 25                         Subtract 10 from both sides.

5x = 25 - 10

5x = 15

First, we'll arrange the number sequence from lowest to highest - 0,50,50,51,52,55,57,57,58,58,58,58,59,60,62,63,64,66,67,67.

Second, we'll find the median Q2 - (58+58) / 2 = 58

Third, we'll take the middle numbers before the median as our lower quartile Q1 - (52+55) / 2 = 53.5

Fourth, we'll take the middle numbers after the median as our upper quartile Q3 - (62+63) / 2 = 62.5

Answer:

C. 20

Step-by-step explanation:

Let's say M is the original number of men and W is the original number of women.

M / W = 3 / 5

(M+2) / (W+1) = 2 / 3

Let's cross multiply both equations:

5M = 3W

3(M+2) = 2(W+1)

Let's simplify the second equation:

3M + 6 = 2W + 2

3M + 4 = 2W

From the first equation:

M = 3/5 W

Substitute:

3 (3/5 W) + 4 = 2W

9/5 W + 4 = 2W

4 = 1/5 W

W = 20

There were originally 20 women.

Let's check our answer.  That would mean that M = 3/5 W = 12.

After 2 men walk in and 1 woman, W = 21 and M = 14, so 14/21 = 2/3.  Looks like the answer is correct!

Answer:

The solution set is {-1, 7}

Step-by-step explanation:

Rewrite x^2-6x=7 as x^2 - 6x                            = 7.

Identify the coefficient of the x term; it is -6.

Halve this coeff (obtaining -3)

Square this result (obtaining 9)

Add 9 to  x^2 - 6x   and then subtract 9 from the result:  x^2 - 6x  + 9 - 9

Then we have:

x^2 - 6x  + 9 - 9 = 7.  Add 9 to both sides, obtaining

x^2 - 6x  + 9       = 16

Rewrite x^2 - 6x  + 9 as the square of a binomial:  (x - 3)^2

Then we have

(x - 3)^2 = 16

Taking the square root of both sides, we get

x - 3 = ±4, so that:  x = 3 + 4 = 7, and x = 3 - 4 = -1.

The solution set is {-1, 7}.

Answer:

To complete the square x^2-6x=7

We take the coefficient of X which is -6

     divide it by 2  -3

     square that number 9

     then add it to both sides of the equation.

x^2 -6x + 9 = 16

(x -3) * (x -3) = 16

We take the square root of both sides:

a) x-3 = 4

b) x-3 = -4

Therefore, x = 7 and x = -1

Step-by-step explanation:

Answer: D; Yes; no vertical line passes through two graphed points.

Step-by-step explanation:

A graph is only considered a function if it passes the vertical line test. The vertical line test is basically when you put a vertical line on any point in the graph, it can’t pass through more than one graphed point. It can only touch the line once. That graph is considered a function because no two points touch a vertical line in the same x-value.

Answer:

Option D.

Step-by-step explanation:

A relation is a function if there exist a unique output for each input value. In other words a relation is a function if there exist a unique value of y for each value of x.

Vertical line test : According to the vertical line test if the graph of a relation intersect any vertical line at most once, then the relation is a function.

From the given table it clear that the ordered pairs of relation are(-5,-5), (-3,-3), (1,1) and (2,2).

For each value of x, there is a unique value of y. It means no vertical line passes through two graphed points. So, the given relation is a function.

Therefore, the correct option is D.
