Answer:

Mean = 59.1, Median = 61

(there might have been a mistake in calculation (a lot of numbers!))

Step-by-step explanation:

The sample size is 40,

Now, the formula for the mean is,

Mean = (sum of the sample values)/(sample size)

so we get,

\(Mean = (49+63+78+22+41+39+75+61+63+65+58+37+45+52+81+75+78+72+68+59+72+85+63+61+75+39+41+48+59+55+61+25+61+52+58+71+75+82+49+51)/40\\Mean = 2364/40\\Mean = 59.1\)

To find the median, we have to sort the list in ascending (or descending)order,

we get the list,

22,25,37,39,39,41,41,45,48,49,

49,51,52, 52,55,58, 58, 59, 59, 61,

61, 61, 61, 63, 63, 63, 65, 68, 71, 72,

72, 75, 75, 75, 75, 78, 78, 81, 82, 85

Now, we have to find the median,

since there are 40 values, we divide by 2 to get, 40/2 = 20

now, to find the median, we takethe average of the values above and below this value,

\(Median = ((n/2+1)th \ value + (n/2)th \ value )/2\\where, \ the\ (n/2)th \ value \ is,\\n/2 = (total \ number \ of \ samples) /2\\n/2=40/2\\(n/2)th = 20\\Hence\ the (n/2)th \ value \ is \ the \ 20th \ value\)

And the (n+1)th value is the 21st value

Now,

The ((n/2)+1)th value is 61 and the nth value is 61, so the median is,

Median = (61+61)/2

Median = 61

Step-by-step explanation:

There are 4850 line segments in the hundredth pattern of the triangular number sequence.

The pattern you're referring to is often called the triangular number sequence. In this sequence, each term represents the number of dots required to form an equilateral triangle with sides of increasing length. To determine the number of line segments in the hundredth pattern, we need to consider the number of sides and diagonals in each triangle.

Let's analyze the pattern step by step:

Pattern 1:

The first pattern consists of a single dot, which does not form any line segments.

Pattern 2:

The second pattern consists of three dots forming an equilateral triangle. It has three sides.

Pattern 3:

The third pattern consists of six dots forming an equilateral triangle. It has three sides and three diagonals.

Pattern 4:

The fourth pattern consists of ten dots forming an equilateral triangle. It has three sides and six diagonals.

We can observe that for each pattern, the number of sides remains constant at 3. However, the number of diagonals increases by one with each pattern. The formula to calculate the number of diagonals in an equilateral triangle is given by:

Number of diagonals = (n * (n - 3)) / 2,

where n represents the number of sides (which is 3 in the case of an equilateral triangle).

Using this formula, we can calculate the number of diagonals for the hundredth pattern:

Number of diagonals = (100 * (100 - 3)) / 2

= (100 * 97) / 2

= 4850.

Since each diagonal forms a line segment, the number of line segments in the hundredth pattern is equal to the number of diagonals, which is 4850.

Therefore, there are 4850 line segments in the hundredth pattern of the triangular number sequence.

Answer:

2923 is your p is equal to 2 and n

a) She can make 400 milliliters of the fizzy drink.

b) The change does not affect the greatest amount of drink.

We know that the fizzy drink is 7 parts apple juice and 3 parts lemonade. And Kerry thinks that she has 280ml of apple juice and 180 ml lemonade.

If we divide the total amount of apple juice in 7 parts, then each part has:

280ml/7 = 40ml

Then we need 3 parts of 40ml of the lemonade, this is:

3*40ml = 120ml

Then the total amounf of drink fizz that she can make is:

280ml + 120ml = 400ml.

b) Now she has  160 ml of lemonade, but she needs 120 ml of it, so this change does not affect the greatest amount of fizzy drink she can make.

Answer:

Step-by-step explanation:

To find out how much money Chelsea will earn next week, you need to multiply her hourly wage by the number of hours she plans to work.

First, convert the number of hours to a decimal by dividing the number of minutes by 60. In this case, 20 1/2 hours is equal to 20.5 hours.

Then, multiply Chelsea's hourly wage by the number of hours she plans to work:

14.60 * 20.5 = 297.3

Therefore, Chelsea will earn $297.30 next week.

If it was -12 and by noon it had risen 23 degrees  just add the two numbers together and you get 11 degrees F

From the given value of z = 3(cos pi/2 + isin pi/2),  the exact value of z⁷ is -2187i.

Given z = 3(cos pi/2 + isin pi/2)

which can be represented as 3sin(pi/2) in polar form.

Now, by applying De-Moivre's theorem,

z⁷  = (3cis(pi/2))⁷

      =   3⁷cis(7pi/2)

      = 3⁷cis(3pi/2)                   [7pi/2 --- 3pi/2 ]

To write it in complex form,

z⁷  = 3⁷(cos(3pi/2) + isin(3pi/2))

z⁷  = 3⁷(0-i)                                    [cos(3pi/2) = 0 and sin(3pi/2) = -1]

z⁷  = 3⁷(-i)

z⁷  = -2187i

From the above explanation, we can conclude that the value of  z⁷ is -2187i.

The order of operations (PEMDAS) states that we should perform multiplication and division before addition and subtraction. Using this order, we get:

244 - (33456 / 3456) * 345 + 13.55 - 2

= 244 - 97.02 * 345 + 13.55 - 2

Answer:

x = 16°

H = 46°

I = 55°

J = 39°

Step-by-step explanation:

Since the whole figure is 180°

Deduct 180 by the numbers mentioned above in order to find x.

180 - 2 - 9 - 9 = 160

3x + 4x + 3x = 10x

10 x = 160

x = 160 ÷ 10 = 16

Since we know what x is, we can find all the angles in the figure.

Angle at H = 3 x 16 - 2 = 46°

Angle at I = 4 x 16 - 9 = 55°

Angle at J = 3 x 16 - 9 = 39°

The value of x is 20.

The total of a triangle's three internal angles is 180 degrees, as stated by the angle sum feature of a triangle. A closed shape with both inner and exterior angles, a triangle is created by three line segments. When the values of the other two angles are known, one can utilise the angle sum property to determine the measure of an unknown interior angle.

Given:

Angles are: 3x-2, 3x-9 , 4x-9

Using Angle Sum Property

3x-2 + 3x -9 + 4x- 9 = 180

10x - 20 = 180

10x = 200

x= 200/10

x= 20

Hence, the value of x is 20.

Answer:

Let's start by assigning a variable to Susan's present age. Let's call it "x".

According to the problem, in seven years, Susan will be "x + 7" years old.

Three years ago, Susan was "x - 3" years old.

The problem tells us that Susan will be 2 times as old in seven years as she was 3 years ago. So we can set up the following equation:

x + 7 = 2(x - 3)

Now we can solve for x:

x + 7 = 2x - 6

x = 13

Therefore, Susan's present age is 13 years old.

Let's assume Susan's present age is "x" years. According to the information provided, "Susan will be 2 times old in seven years as she was 3 years ago."

Seven years from now, Susan's age would be x + 7, and three years ago, her age would have been x - 3. According to the given statement, her age in seven years will be two times her age three years ago:

x + 7 = 2(x - 3)

Let's solve this equation to find Susan's present age:

x + 7 = 2x - 6

Subtracting x from both sides:

7 = x - 6

Adding 6 to both sides:

13 = x

Therefore, Susan's present age is 13 years.

Answer:

The measure of the vertex angle is 94 degrees ⇒ A

Step-by-step explanation:

∵ In an isosceles triangle, the measure of the base angle = (2x + 5)

∵ The base angles of the isosceles triangles are equal in measures

∴ The measures of the base angles are (2x + 5), (2x + 5)

∵ The measure of the vertex angle = (5x - 1)

∵ The sum of the measure of the three angles = 180°

∴ (2x + 5) + (2x + 5) + (5x - 1) = 180

→ Add the like terms in the left side

∵ (2x + 2x + 5x) + (5 + 5 + -1) = 180

∴ 9x + 9 = 180

→ Subtract 9 from both sides

∴ 9x + 9 - 9 = 180 - 9

∴ 9x = 171

→ Divide both sides by 9 to find x

∴ x = 19

→ Substitute the value of x in the measure of the vertex angle to find it

∵ The measure of the vertex angle = 5x - 1

∴ The measure of the vertex angle = 5(19) - 1

∴ The measure of the vertex angle = 95 - 1

∴ The measure of the vertex angle = 94°

∴ The measure of the vertex angle is 94 degrees

Let the original amount in the bowl be x. Thus;

If Amelia grabbed 50%, then amount left = (100% - 50%)x = 50%x = 0.5x

Now, we are told that domicick took 50% of what was keft after amelia. Thus; New amount left = 100%x - (0.5x + 0.25x) = 0.25x
