7. A random selection will be made from a bag containing different
colored disks. Of the 25 disks in the bag, 5 are yellow,
so P(yellow) - 25
a. The probability that a yellow disk will be selected is O is
b. Complete the sentence to describe the likelihood of randomly
selecting a yellow disk,
It is
that a yellow disk will be randomly selected
from the bag.
Probability of yellow disk will be selected is [tex]\frac{4}{5}[/tex]. probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given
n(S) = 25
a. Probability of yellow disk will be selected is O is
n(E) = 25 - 5 = 20
P(E) = [tex]\frac{n(E)}{n(S)}[/tex] = [tex]\frac{20}{25}[/tex] = [tex]\frac{4}{5}[/tex]
b. It is the probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.
Hence, Probability of yellow disk will be selected is [tex]\frac{4}{5}[/tex]. probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.

Write down an algebraic expression for each of the following statements.
A. Subtract the cube root of the product of x and 3y from the square of the sum of a and b.
B. The total value of x 20-cent coins and y 5-dollar notes in cents.
Answer:
A) [tex](a+b)^{2}- \sqrt[3]{x . 3y}[/tex]
B) 20 x + 500 y
Step-by-step explanation:
A. Subtract the cube root of the product of x and 3y from the square of the sum of a and b.
A = The square of the sum of a and b is [tex](a+b)^{2}[/tex]
B = The cube root of the product of x and 3y is [tex]\sqrt[3]{x . 3y}[/tex]
They want us to subtract B from A so B - A, therefore the following.
[tex](a+b)^{2}- \sqrt[3]{x . 3y}[/tex]
B. The total value of x 20-cent coins and y 5-dollar notes in cents.
20x cents is already provided as they want the expression in cents. Moving on to the $5 dollar note. We will have to convert this $5 into cents in order to fulfill the question requirements.
Convert:
1 dollar = 100 cents
5 dollars = 100x5 = 500 cents
Therefore, 5y dollars = 500y cents. Finally, we end up with the following answer.
20 x cents + 500 y cents
20 x + 500 y

At practice, Carlos eats half as many apples as Alex, and also eats 2 tangerines. He eats 4 pieces of fruit in total. The equation 0.5x + 2 = 4 describes this situation. What does the variable represent?
Answer:
Step-by-step explanation:
In this scenario, the variable x represents the total number of apples that Alex has eaten. Since Carlos has eaten half as many apples as Alex this would be represented as 0.5 and is why it is being multiplied by the variable x. The 2 in this scenario represents the tangerines that Carlos has also eaten, while the 4 represents the total number of fruits that Carlos has eaten.

The maximum marks of each subject are 150. A student scores 80% in Maths. In English, he scores 70% of his
score in Maths and in
Hindi, he scores 75% of his score in English. Find his score in each subject.
Answer:
Maths = 120
English = 84
Hindi = 63
Step-by-step explanation:
First, solve for Maths since the others require that answer.
Using decimals, 80% of 150 can be written as 0.8 x 150 = x (where x is 80% of 150).
0.8 x 150 = x
120 = x
Since you know the score for maths, you can find the score for english, which is 70% of 120.
0.7 x 120 = y
84 = y
Since you now have the score for English too, that can be used to find the score for Hindi, which is 75% of the English score (84)
0.75 x 84 = z
63 = z

point.
y=
-(4,-3)
Answer:
hopes this helps
Step-by-step explanation:
First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.

Answer:
y = x + 8
Step-by-step explanation:
Answer:
To determine if a point is on a line you can simply subsitute the x and y coordinates into the equation. Another way to solve the problem would be to graph the line and see if it falls on the line. Plugging in will give which is a true statement, so it is on the line.

The Height of triangular face is 692.820 feet,
The height of Pyramid is 800 feet.
What is pyramid?A pyramid is a three-dimensional polyhedron with three or more faces that are triangle-shaped and meet above the base. Faces are the triangular sides, and the apex is the point above the base. A pyramid is made by interfacing the base to the peak. To differentiate them from the base, the triangular sides are sometimes referred to as lateral faces. Each edge of the base of a pyramid connects to the apex that makes up the triangular face.
Given to Draw a Pyramid, with square base
and triangular faces are Equilateral,
length of Square base = 800 feet
The Drawing of pyramid is attached,
which shows h = height of pyramid
S = height of Triangular face
And base = 800 feet
2: To find height of Triangular face
since triangular face are Equilateral
side of triangle = base of pyramid = 800 feet
and height of Equilateral triangle = √3/2 × a
where a is side of triangle
S = √3/2 × a = √3/2 × 800
S = 692.820 feet
3: As we have height of triangle so we can calculate the height of pyramid by relation between height of triangle and height of pyramid
h² = S² + (x/2)²
where x is the length of side of base,
x/2 = 800/2 = 400
substitute values of S and x/2
h² = (400√3)² + (400)²
h² = 480000 + 160000
h² = 640000
h = 800 feet
Hence, the height of triangular face is 692.820 feet,
and the height of Pyramid is 800 feet.
