Answer:

a. M = 50

b. M = 242

Step-by-step explanation:

mean =  [tex]\frac{sum of scores}{number of samples}[/tex]

⇒ sum of scores = mean x number of samples

Let the mean be represented by M, and the number of samples be represented by n,

sum of scores = M x n

a. When n = 5 for both samples,

The first sample's sum of scores = M x n

                                     = 7.2 x 5

                                     = 36

The second sample's sum of scores = M x n

                                     = 12.8 x 5

                                     = 64

The mean for the sum of scores of the combined set = [tex]\frac{36 + 64}{2}[/tex]

                                     = 50

When both samples have n = 5, the mean of the combined set is 50.

b. When the first sample has n = 5, the sum of scores = 36.

If n = 35 for the second sample, the sum of scores = M x n

                                                          = 12.8 x 35

                                                          = 448

The mean for the sum of scores of the combined set = [tex]\frac{36 + 448}{2}[/tex]

                                                    = 242

Step-by-step explanation:

Answer:

Step-by-step explanation:

Her former rent is $ x

Twice the former rent: 2*x = 2x

$300 less than 2x: 2x - 300

2x - 300 = 550

Add 300 to both sides

2x - 300 + 300 = 550  + 300

                    2x = 850

Divide both sides by 2

               2x/2 = 850/2

x = 425

Her former rent = $425

In this question, the older and newer rents of a student in two apartments in given. And some conditions and information is also provided,

GiveN:

We have find her rent in the previous apartment.

Let her previous rent be $ x

Then according to question,

➝ $ 550 = 2x - $ 300

Adding $ 300 both sides,

➝ $ 550 + $ 300 = 2x

Flipping it,

➝ 2x = $ 850

➝ x = $ 425

So, The previous rent of the student:

[tex] \huge{ \boxed{ \bf{ \$ \: 425}}}[/tex]

And we are done !!

Answer:

It is possible.

Step-by-step explanation:

Each piece of cheese can be divided into two equal pieces.

Therefore, the 15 different pieces can produce 30 (15 * 2) equal pieces.

Then there will be 15 pieces in each group.

Provided during the division, it is ensured that equal weights were allocated to each piece, then each group will have the same weight as the other group.

Note that the division of the 15 pieces of cheese into two equal parts looks like the only way to have equal weight of two groups of the delicacy.

Step-by-step explanation:

Let [tex]x[/tex] equal the original price.

[tex]12,000+2000=2x[/tex]

Combine like terms.

[tex]14,000=2x[/tex]

Divide by the coefficient of [tex]x[/tex], which in this case is [tex]2.[/tex]

[tex]7,000=x[/tex]

If you like the variable on the left, rewrite:

[tex]x=7,000[/tex]

Step-by-step explanation:

From the image attached, the length of the bouncy castle is X² +4 and the width is 2x² - 3x  +7

The bouncy castle is a rectangle. A rectangle is a quadrilateral in which opposite sides are equal and all the angles have equal measures. The diagonals of a rectangle also bisect each other. The perimeter of a rectangle = 2(length + breadth), Hence for the bouncy castle:

Perimeter of castle = 2(length + breadth) = 2(x² + 4 + (2x² - 3x  +7)) = 2(3x² - 3x + 11) = 6x² - 6x + 22

Perimeter of castle = 6x² - 6x + 22

The area of the castle = length × breadth = x² + 4 × (2x² - 3x  +7)) = 2x⁴ - 3x³ + 7x² + 8x² - 12x + 28 = 2x⁴ - 3x³ + 15x² - 12x + 28

Answer:

a) Jasmine or Jasmina is correct about the silicone sealant cones.

If Jasmine orders two regular cones of regular sealant, it will be equal to the Jumbo cone of sealant, because the top diameter when put together in a Jumbo cone will give the same result as a Jumbo cone, since 4 * 2 = 8 inches (top diameter) and 6 * 2 = 12 inches (height).

b) If the price for a regular cone of sealant is $3.40, the 'fair price' for a jumbo cone should be $6.80 ($3.40 * 2).

Step-by-step explanation:

Jumbo cone of sealant has top diameter of 8 inches and a height of 12 inches

Regular cone of sealant has top diameter of 4 inches and a height of 6 inches

If Jasmine orders two regular cones of regular sealant, it will be equal to the Jumbo cone of sealant, because the top diameter when put together in a Jumbo cone will give the same result as a Jumbo cone, since 4 * 2 = 8 inches (top diameter) and 6 * 2 = 12 inches (height).

If the price for a regular cone of sealant is $3.40, the 'fair price' for a jumbo cone should be $6.80 ($3.40 * 2), since two of the regular cone will give the value of a Jumbo cone.

The correct answer is A. 12

Explanation:

In mathematics, odd numbers are those numbers that cannot be divided into 2 without using a decimal number, for example, 13 ÷ 2 = 2.5 (decimal number). This does not occur with even numbers such as 26 because these can be divided into 2 and the result is an integer rather than a decimal (26 ÷ 2 =13).

On the other hand, a counterexample is a situation that shows an exception to the rule. In the rule "All multiples of 3 are odd", one counterexample is the number 12 because this is an even number (12 ÷2 = 6). Moreover, this number is a multiply of 3 as 3 can be multiplied by 4 to obtain 12, which shows multiplies of 3 can be even numbers.

Step-by-step explanation:

Given

The list of options

Required

Which represents the strongest correlation.

When [tex]r-value > 0.7[/tex], it is considered to be strong.

Compare this condition with the given options, we're left with:

[tex]r-value = 0.73[/tex]

[tex]r-value = 0.99[/tex]

The above r-values show strong correlation.

However

[tex]r-value = 0.99[/tex] is stronger

because [tex]0.99 > 0.73[/tex]

Hence;

[tex]r-value = 0.99[/tex] answers the question

angle FEB = angle ABE ( Alternate Interior Angles )

angle FEB = 4x = angle ABE

x + 4x + 65° = 180° ( sum of the Angles On the same line is equal to 18° )

or, 5x = 180° - 65°

or, x = 115/5

or, x = 23

The value of x is 23°.

4x = 4(23) = 92°.

A bisector is a line that divides an angle or a line into equal halves. In the case of a given line, the bisector will always be perpendicular to it.

To bisect CD, draw CD to the required length.

Open the compass to a radius greater than the the middle of CD.

With C as the center and the radius, describe an arc above and below CD. Repeat the same using D as the center.

Join the point of intersection of the two arcs by a line.

Label the point where the bisector passes through CD as M.

Step-by-step explanation:

The total distance from Duncan's start on the diving board to his lowest point beneath the surface of the pool will be 12 feet.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Duncan is excited to begin diving lessons. He starts on the diving board, 5 feet above the surface of the pool. Then, Duncan dives off the board and ends up 7 feet below the surface of the pool.

Distance = 7 + 5
Distance = 12 feet

Therefore, the total distance from Duncan's start on the diving board to his lowest point beneath the surface of the pool will be 12 feet.
