Answer:

Mean: 4

Mode: 4

Median: 6

Range: 5

Step-by-step explanation:

Mean: The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Mode: Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Median: The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!

Range: The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest.

Answer:

each base angle is 70°

Step-by-step explanation:

this is an isosceles triangle because two sides are equal which means two angles are equal

the left, right base angle is also 'x'

so, x + x + 40 = 180

2x = 140

x = 70

1/2

Step-by-step explanation:

type it into the calculator

The value of logarithm log base 4(2 is 1/2.

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b.

Given:

Rewrite as an equation.

log base 4(2)=x

and, Rewrite log base 4(2)=x in exponential form using the definition of a logarithm. If x and b  are positive real then

log (base b) x= y equivalent to [tex]b^y[/tex] = x

Create expressions in the equation that all have equal bases.

log base 4(2)=x

[tex](2^2)^x[/tex] = 2

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

2x = 1

x= 1/2.

#SPJ5

Answer:

260 gallons

Step-by-step explanation:

An estimate of 26.5​% of the water used each day is for cleaning and a family uses 68.9 gallons of water a day for cleaning​,

Percentage of water used for cleaning= 26.5%

Gallons of water used for cleaning= 68.9

Let the number of gallons used everyday be represented by g. This will give:

26.5% of g = 68.9

26.5/100 × g = 68.9

0.265 × g = 68.9

0.265g = 68.9

Divide both side by 0.265

0.265g/0.265 = 68.9/0.265

g= 260

260 gallons of water are used everyday

Answer:

(2, 6).

Step-by-step explanation:

The solution is the ordered pair where the 2 lines intersect.

Answer:

(2, 6)

Step-by-step explanation:

Take a look at the graph.

The problem has rather helpfully graphed out the two equations presented to us, and the point in which both lines intersect is (2, 6), making this pair your solution.

If you'd like to check, plug in the corresponding variables.

x = 2

y = 6

First equation:

y = x + 4

6 = 2 + 4

6 = 6

The equation is true.

Second equation:

y = -0.5x + 7

6 = (-0.5 x 2) + 7

6 = -1 + 7

6 = 6

This equation is true as well.

Answer:

r = 2.7%

Step-by-step explanation:

Interest rate compounded continuously

r = ln(A/P) / t

Where,

r = interest rate

A = future value

P = principal

t = time

r = ln(A/P) / t

r = ln(13,006.40/8,000) / 18

= ln(1.6258) / 18

= 0.4860000023303 / 18

= 0.0270000001294

Approximately

r = 0.027

Convert value of r to percentage

r = 0.27 × 100

r = 2.7%

Answer:

x = sqrt(37)/2 - 3/2

approximately 1.54

Step-by-step explanation:

Solve for x over the real numbers:

4 x^2 + 12 x = 28

Divide both sides by 4:

x^2 + 3 x = 7

Add 9/4 to both sides:

x^2 + 3 x + 9/4 = 37/4

Write the left hand side as a square:

(x + 3/2)^2 = 37/4

Take the square root of both sides:

x + 3/2 = sqrt(37)/2 or x + 3/2 = -sqrt(37)/2

Subtract 3/2 from both sides:

x = sqrt(37)/2 - 3/2 or x + 3/2 = -sqrt(37)/2

Subtract 3/2 from both sides:

Answer: |

| x = sqrt(37)/2 - 3/2 or x = -3/2 - sqrt(37)/2

Answer: B is the correct answer

Step-by-step explanation:

If you do the math for each question to get a price a leaves you with 725 and b leaves you with 720 and c leaves you with 760 while d leaves you paying 800 so the lowest amount would be B.

Answer: B

Step-by-step explanation:

I'm pretty sure its B.

Since all 4 stores have a 5% sales tax already on them, we do:

800 x 5%

800 x 5/100

800 x 0.5 = 40

So now we go to all the stores and see which one is less than $40.

Answer A = 40 - 75 = -35 (Which is a price the store would have to pay but that's not a good option)

Answer B = 4

40 x 10%

40 x 10/100

40 x 0.10 = 4

Answer C = So if the store already pays sales tax which would be the 5% then our answer is $40

Answer D = This would just be $800 since the store says "no tax" and the store pays the 5%.

So, i'm pretty sure the answer is B instead of C. (i say this because a lot of people were saying it was C but C is completely wrong.)

Answer:28\2

Step-by-step explanation:

7+7=14

7+7=14

14+14=28

Triangle A=1\2bh

So 28\2

The pebbles cover an area of 147 sq ft. We can use the Pythagorean theorem to find the solution.

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Now, Let's call the length of the third side of the triangle "x".

Since the two triangles are equal in size, and they share two sides with the square, we can use the Pythagorean theorem to find x.

a² + b² = c²

7² + 7² = c²

49 + 49 = c²

98 = c²

c = √(98)

c = 7 √(2)

So, each triangle has a base of 7 ft and a height of 7 √(2) ft.

And, Area of each triangle = (base × height) / 2

                                          = (7 × 7√(2)) / 2

                                          = 24.5 ft²

Since, there are two triangles,

Hence, the total area of the grass is,

⇒ 24.5 sq ft × 2 = 49 sq ft

Hence, The square has an area of,

⇒  14ft × 14ft = 196 sq ft

So, The pebbles cover an area of,

⇒ 196 sq ft - 49 sq ft = 147 sq ft.

Answer:

(-4).(-4) = 4^2

Step-by-step explanation:

First, some rules that we need to remember:

if A is a positive number, then:

-A = (-1)*A

Also:

A*A = A^2

We also should remember that we can multiplicate in any order we want, this is:

A*B*C = (A*B)*C = A*(B*C)

And we also can change the order of the numbers:

A*B = B*A

And finally, we need to remember the sign rules for multiplication.

(+)*(+) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(-)*(-) = (+)

Ok, now let's look at our expression.

(-4)*(-4)

First, we can rewrite this as:

( (-1)*4)*((-1)*4)

And we can rearrange the numbers to:

(-1)*(-1)*4*4

Now let's multiplicate the first two ones, because of the sign rule, we know that the outcome will be positive, and 1 times 1 is equal to 1,

(-1)*(-1) = 1

Then:

(-1)*(-1)*4*4 = 1*4*4 = 4*4

And we know that when a number is multiplied by itself we can rewrite it as:

4*4 = 4^2

Then:

(-4).(-4) = 4^2

The simplified expression is 4^2

Answer:

EF = 26

Step-by-step explanation:

From the question, we have that arc EF and arc CD are equal

what this indicates is that the line that bounds these arcs too will be equal

Hence, CD equals EF

Thus;

9x-1 = 41-5x

9x + 5x = 41 + 1

14x = 42

x = 42/14

x = 3

Recall;

EF is 41-5x

EF = 41-5(3)

EF = 41-15

EF = 26
