How many combinations with repetition are allowed if n = 7 and r = 2?
a. 21
b. 14
c. 49
d. 28
The combinations with repetition are allowed is equal to 28.
Here we have N=7 r=2
We have to determine the combination of repetition
What is the combination?
A combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.
The combinations with repetition are allowed if n = 7 and r = 2
So 7x2=14
7x3=21
7x4=28
Therefore the combinations with repetition are allowed is equal to 28.

As shown, several colored paper squares are placed in a bowl. One paper square is randomly selected. Is this a uniform or non-uniform probability model? Justify your reasoning. A) It is a uniform probability model because each color has an equal chance of being selected. B) It is a non-uniform probability model because each color has an equal chance of being selected. C) It is a uniform probability model because each color does not have an equal chance of being selected. D) It is a non-uniform probability model because each color does not have an equal chance of being selected.
Answer:
B it is a non-uniform probability model because each color has an equal chance of being selected
Step-by-step explanation:
Developing a uniform probability model by assigning equal probability to all. If we select one student at random from the ten, is that a uniform then student name or grade level or color of their shirt or shoe size or different that the probability model uniform is different so that means the model is a non-uniform

Find the range & interquartile range of the data set represented by this box plot.
Answer:
60 and 25
Step-by-step explanation:
The range is the difference between the maximum value and the minimum value.
maximum value = 125, minimum value = 65
range = 125 - 65 = 60
------------------------------------------
The interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box = 115
Q₁ is the value at the left side of the box = 90
interquartile range = 115 - 90 = 25

Step-by-step explanation:
[tex](y + 6 = x) \times (x - 6 = y) = {40}^{2} feet \\ 6 \times 6 = 36 \\ 40 - 36 = 4 \\ (4 + 6 = 10) \times (10 - 6 = 4) \\ 10 \times 4 \\ = 40[/tex]

Answer:
Please check explanations
Step-by-step explanation:
To find the volume of the surface area of a cone, we need to use the height and not the slant height of the cone
The slant height, the height and the base radius forms a right triangle with the slant height being the hypotenuse of this triangle
By Pythagoras’ theorem, the square of the hypotenuse (slant height) equals the sum of the squares of the two other sides
6.5^2 = 2.5^2 + h^2
h^2 = 36
h = √36
h = 6 cm
So we have the volume as;
V = 1/3 * pi * r^2 * h
where r in this case is base radius of 2.5 cm
V = 1/3 * pi * 2.5^2 * 6 = 39.3 cm^3
What is the area of this figure?

The function f(x) after evaluation at {x} = 2 is equal to 67.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of function as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to evaluate the function f(x) = x⁴ + 6x³ + 3 at {x} = 2.
The given function is -
f(x) = x⁴ + 6x³ + 3
Now, for {x} = 2, we can write that -
f(2) = 2⁴ + 6(2)³ + 3
f(2) = 16 + 6 x 8 + 3
f(2) = 16 + 48 + 3
f(2) = 67
Therefore, the function f(x) after evaluation at {x} = 2 is equal to 67.

The length of a rectangular garden is 5 meters more than its width. If the
area of the rectangular garden is 150 m2, identify the equation used to find
the width of the rectangular garden.
O W(W+5) = 150
O W(W + 5) 22 = 150
O 1/2(2W + W) = 150
O 2W(W + 5) = 150
Answer:
Width of rectangular garden = 10 meter
Step-by-step explanation:
Given;
Area of rectangle garden = 150 m²
Length of rectangular garden = 5 meters more than its width
Find:
Width of rectangular garden
Computation:
Assume;
Width of rectangular garden = W
So,
Length of rectangular garden = 5 + W
Area of rectangle garden = length x width
(W)(W + 5) = 150
W² + 5W = 150
W² + 5W - 150 = 0
W² + 15W - 10W - 150 = 0
W(W + 15) - 10(W + 15) = 0
(W + 15)(W - 10)
So,
W = -15, W = 10
Width of rectangular garden = 10 meter

Answer:
h = 3 cm
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated as
V = Ah ( A is the area of the base and h the height )
Here V = 36 and A = 6 × 2 = 12 cm² , then
12h = 36 ( divide both sides by 12 )
h = 3
Answer: 3 cm
Step-by-step explanation:
The formula to solve the volume of a rectangular prism is V = l x w x h
Where V is volume, l is length, w is width, and h is height
Givens are, Volume = 36 cm3
length = 6 cm
width = 2 cm
Now, we will plug in the numbers to the formula
36 cm3 = 6cm x 2cm x h
36 cm3 = 12 cm2 x h
divide 12cm2 on both sides
36cm3/12cm3 = h
h = 3cm
