Step-by-step explanation:
Step by step-
1. Find common denominator
2. Combine fractions with common denominator
3. Multiply the numbers
4. Multiply all terms by the same value to eliminate fraction denominators
5. Cancel multiplied terms that are in the denominator
6. Multiply the numbers
7. Add 10 to both sides of the equation

If I had 60 units needed and units per case was 14 how many full cases and additional items are needed to fufill the order
Answers
60 units / 14 units per case ≈ 4.29 cases
Since you can't have a fractional number of cases, you would need to round up to the nearest whole number of cases. Therefore, you would need 5 full cases.
To determine the number of additional items needed to fulfill the order, you can subtract the number of units in the full cases from the total number of units:
60 units - (5 cases * 14 units per case) = 10 additional items
So, in total, you would need 5 full cases and 10 additional items to fulfill the order of 60 units.

On solving the provided question, we can say that the probability of the red die rolling is 16.67% probability = 0.1667
What is probability?A branch of mathematics called probability theory determines the chance that an event will occur or that a statement is true. A probability is a number between 0 and 1, where 1 denotes certainty and about 0 denotes how probable an event is to occur. The possibility or likelihood that a specific event will occur is expressed numerically as a probability. Probabilities can also be expressed as percentages from 0% to 100% or as numbers between 0 and 1. the proportion of occurrences among all equally likely alternatives that lead to a certain event relative to all possible outcomes.
red die, there are 3 numbers greater than 3 out of 6 numbers
Probability (A) = 3/6 = 1/2.
green die, there are 2 numbers less than 3 out of 6 numbers
Probability (B) = 2/6 = 1/3.
events are independent
P(A and B) = \(P(A)P(B) = 1/2 X 1/3 = 1/6 = 0.1667\)\(P(A)P(B) = 1/2 X 1/3 = 1/6 = 0.1667.\)

the respone times for a certain ambulance company are normally distributed with a mean of 13 minutes.95% of the response times are between 10 and 16 minutes
Answers
The standard deviation of the response time is 1.53 minutes.
What is the standard deviation of the response time?To get standard deviation, we will determine z-scores corresponding to the given percentiles and use them to calculate the standard deviation.
Z-score = z = (x - μ) / σ
For the lower bound of 10 minutes:
z = (10 - 13) / σ
For the upper bound of 16 minutes:
z = (16 - 13) / σ
As normal distribution is symmetric, the z-score corresponding to the lower tail of 2.5% is -1.96, and the z-score corresponding to the upper tail of 2.5% is 1.96.
Using z-scores, we set up equations:
(10 - 13) / σ = -1.96
(16 - 13) / σ = 1.96
Solving the first equation:
-3 / σ = -1.96
σ = -3 / -1.96
Solving the second equation:
3 / σ = 1.96
σ = 3 / 1.96
Dividing both sides by 1.96:
-3 / 1.96 = σ
1.53 = σ

suppose y varies directly as x, and y=48 when x=6. find x when y=72.
Answers
Using the constant of proportionality the value of x when y is 72 is 9.
What is a COP?
The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.
If y varies directly as x, it means that y can be expressed as a constant multiple of x, i.e., y = kx, where k is the constant of proportionality.
To find k, we can use the given information that y = 48 when x = 6 -
y = kx
48 = k(6)
k = 8
Now that we know k, we can use it to find x when y = 72 -
y = kx
72 = 8x
x = 9
Therefore, when x = 72, the value of x = 9.

What is vertical stretch factor?The vertical stretch factor is a term used in mathematics to describe the transformation that changes the height of a graph while leaving the horizontal axis unchanged. In other words, it's a factor by which the y-values of a function are multiplied to produce a new, stretched or compressed version of the original graph.
The stretch factor is usually represented by the symbol "k". For example, if the equation of a function is y = f(x), then the equation of its vertically stretched image would be y = k * f(x). A positive value of k stretches the graph upward, while a negative value of k compresses the graph downward. If k > 1, the graph is stretched vertically; if 0 < k < 1, the graph is compressed vertically; if k = 1, the graph remains unchanged.

Kimberly had 2 times as many marshmallows as Chris. After eating 15 each, Kimberly had 3 times as many marshmallows as Chris. How many marshmallows did Kimberly have at first?
Answers
Kimberly had 2 times as many marshmallows as Chris. After eating 15 each, Kimberly had 3 times as many marshmallows as Chris. Kimberly had 60 marshmallows at first.
What is Kimberly's marshmallows count?Generally, Let's call the number of marshmallows that Kimberly had at first X.
We know that Kimberly had 2 times as many marshmallows as Chris at first, so Chris had X/2 marshmallows.
After eating 15 each, Kimberly had X - 15 marshmallows, and Chris had X/2 - 15 marshmallows.
We also know that Kimberly had 3 times as many marshmallows as Chris after eating 15 each, so
(X - 15) = 3 * (X/2 - 15).
(X - 15) - 3 * (X/2 - 15) = 0
Then, we can simplify the left side of the equation:
X - 15 - 3 * X/2 + 45 = 0
Combining like terms, we get:
-3 * X/2 + X - 15 + 45 = 0
Simplifying further:
-X/2 =-30
X = 60
Therefore, Kimberly had 60 marshmallows at first.

The image for P(9, 1.5) after Translation is P'( 12, 1).
What is Translation?Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.
For example, this transformation moves the parallelogram to the right 5 units and up 3 units. It is written ( x , y ) → ( x + 5 , y + 3 ) .
Given:
P(9, 1.5) with Translating Vector (3, -0.5).
So, Applying the Translation we get
P(9 + 3, 1.5 + (-0.5))
= P(12 , 1.5- 0.5)

Evaluating the function valuesA composite function is a function that results from combining two or more functions. It is created by using the output of one function as the input of another function.
The function g(x) is defined as g(x) = 11, which means that the output of the function is always 11, no matter what value of x is inputted.
i.e. the function g(x) = 11 always returns the value 11, regardless of the input.
Therefore, we have:
