Answer:
5/36
Step-by-step explanation:
number cubes are rolled = dies that have 6 faces with numbers 1,2,3,4,5,6
Getting 5 or 4 as the product of the two numbers.
How many ways we can get 5 or 4 as a product?
5 ways : 1*4, 1*5, 2*2, 4*1, and 5*1
All possible outcomes are 36 (see table)
P = ways to get 4 or 5 as a product/ all possible ways = 5/36

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/
7
is 7/
2
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, the fraction result cannot be further simplified by canceling.
In other words - nine fifths divided by two sevenths = sixty-three tenths.

What is 3 3/7 in it's simplest form?
Answer:
Mixed Number: 3 3/7
Improper Fraction: 24/7
Step-by-step explanation:
3 3/7 is already in its simplest form. However, we can also turn it into an improper fraction.
3 3/7 --> 24/7
You get that by multiplying 3 and 7 (21) and then adding the numerator (3) to get 24. The denominator (7) remains the same. All in all, it becomes: 24/7

A.Two cards are drawn (with replacement).
B.Die is thrown and a coin flipped.
C.A die is thrown and the same die is thrown again.
D.Two marbles are pulled from a deck (without replacement)
Answer: A and D
Step-by-step explanation: A and D are the only events in which only one type of object is used.
All the situations that are independent are B. Die is thrown and a coin is flipped, C. A die is thrown and the same die is thrown again and D. Two marbles are pulled from a deck (without replacement).
How do you calculate Probability?
The Probability of an event can be calculated through chance formulation via absolutely dividing the favorable quantity of outcomes through the overall wide variety of possible effects.
How do you provide an explanation for probability?Probability is the threat that something will show up, or how probable it is that an event will occur. when we toss a coin inside the air, we use the phrase possibility to refer to how likely it's miles that the coin will land with the heads aspect up.

What is the greatest common factor of 64xyz−36xy+24x?
1) Find the Greatest Common Factor (GCF).
4x
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
[tex]4x(\frac{64xyz}{4x} +\frac{-36xy}{4x} +\frac{24x}{4x})[/tex]
3) Simplify each term in parentheses.
[tex]4x(16yz-9y+6)[/tex]
The greatest common factor of equation A = 64xyz - 36xy + 24x is 4x
A = 4x ( 16yz - 9y + 6 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given by
A = 64xyz - 36xy + 24x
Now , the Greatest Common Divisor is the highest number that divides exactly into two or more numbers. It is also expressed as GCF
So , the equation A can be factorized as
Taking 4x as the common term of the equation , we get
A = 4x ( 16yz - 9y + 6 )
So , the common term is 4x and the greatest common factor of the equation A is 4x
Therefore , the GCF is 4x
Hence , The greatest common factor of equation A = 64xyz - 36xy + 24x is 4x and A = 4x ( 16yz - 9y + 6 )
