You select a marble without looking and then put it back. If you do this 48 times, what is the best prediction possible for the number of times you will pick a green or an orange marble?

Answers
Step-by-step explanation:

Answer:
The best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.
Step-by-step explanation:
If there are 5 orange marbles and 7 green marbles out of a total of 48 marbles, the best prediction for the number of times you will pick a green or an orange marble would still be proportional to the ratio of green and orange marbles.
The ratio of green marbles to the total number of marbles is 7/48, and the ratio of orange marbles to the total number of marbles is 5/48.
To predict the number of times you will pick a green marble, you can multiply the total number of selections (48) by the ratio of green marbles:
48 * (7/48) = 7
Similarly, to predict the number of times you will pick an orange marble:
48 * (5/48) = 5
Therefore, the best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.

Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger block?
Answers
Answer:
1:25
Step-by-step explanation:
Scale factor= 1:25
Answer:
The Scale factor is 5.
Step-by-step explanation:
Because the area has cm^2 to find the scale factor you find the number it takes to get from one area to the next and take the square root.
4X = 100
X = 100/4
X = 25 (Take the sqrt because of area)
X = sqrt(25)
X = 5
The Scale factor is 5.

a and are different numbers that are selected from the first 25 whole numbers: 1 through 25.If a is greater than b, what is the smallest value the expression could have?
Answers
Answer:
The smallest value the expression could have is 1.
Step-by-step explanation:
If a and b are different numbers selected from the first 25 whole numbers (1 through 25), and a is greater than b, the smallest value the expression could have is when b is the smallest possible value and a is the next smallest value.
The smallest possible value for b is 1, and a must be greater than b. Therefore, the smallest possible value for a is 2.
So, the smallest value the expression could have is 2 - 1 = 1.

Given the inequality 5(n − 4) < 4(n + 15), determine which integer makes the inequality false.
S:{80}

S:{5}

Answer:
-9
Step-by-step explanation:
5(-9-4)
5(-13)
-65
4(-9+15)
4(6)
24
-65<24 so -9 is false because -65 is not smaller than 24
The solution is Option A.
The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is given by
5 ( n − 4 ) < 4 ( n + 15 )
Now , on substituting the value of n as 80 in the inequality equation , we get
5 ( n − 4 ) < 4 ( n + 15 )
when n = 80
5 ( 80 - 4 ) < 4 ( 80 + 15 )
5 ( 76 ) < 4 ( 95 )
380 = 380
So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80
Hence ,
The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

Given:
Total price: n = $307.32
Tax or tip rate: 20%
Let m be the original price.
So,
Tax = Original Price x Tax %/100
Tax = 307.32 × 20/100
Tax = 307.32 x 0.2
Tax = $61.46
Original Price = Original Price - Tax
Original Price = 307.32 - 61.464
Original Price = $245.86
Therefore, $245.86 is the price.

An isosceles triangle in which the two equal sides, labeled a, are longer than the base, labeled b. This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base? 6.3+b=15.7 12.6+b=15.7 2a+6.3=15.7 2a+12.6=15.7
Answers
Hey There!!
The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
Thus, answer is base=3.1 cm

The base of the pyramid below is a square that has an area of 64 square inches.
Suppose that the pyramid is sliced so that the cross-section is a square with an area of 49 square inches.
How can you slice the pyramid to get that square?
Answers
The height of the pyramid must be sliced by a factor of 7/8
How to slice the pyramid to get the square?From the question, we have the following parameters that can be used in our computation:
Area of base of the pyramid = 64 square inches.Area of cross-section of the pyramid = 49 square inches.The base length of the pyramid is
L^2 = 64
L = 8
For the cross-section, we have
l^2 = 49
l = 7
Using the similar shapes, we have the height h to be
(L - l)/h = l/L
So, we have
(8 - 7)/h = 8/7
This gives
1/h = 8/7
Evaluate
h = 7/8
This means that the height of the pyramid must be sliced by a factor of 7/8
