rumba got 250 marks !!
if she had got 30 more marks then she would had passed the exam,
So, passing marks :
=》250 + 30
=》 280 marks
now, passing percentage :
=》
[tex] \dfrac{passing \: \: marks}{total \: \: marks} \times 100[/tex]
=》
[tex] \dfrac{280}{700} \times 100[/tex]
=》
[tex] \dfrac{280}{7} [/tex]
=》
[tex]40[/tex]
Hence, the passing percentage is 40%
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

620 000 divided by 10 to the 3rd power
Answer:
620
Step-by-step explanation:
Not only you can find it, but 10 to the third power is 1,000 and 620,000 divided by 1,000 is subtracting the three 0s from it which would equal 620.
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

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.

Explain Jan’s error
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
