What is the quotient?
-5 1/4 ÷ 2 3/4
Enter your answer as a mixed number, in simplified form, in the box.
To divide -5 1/4 by 2 3/4, convert both numbers to improper fractions, multiply the first fraction by the reciprocal of the second fraction, and simplify the result. The quotient is -1 10/11.
Explanation:To divide -5 1/4 by 2 3/4, first convert both mixed numbers to improper fractions. -5 1/4 can be written as -21/4, and 2 3/4 can be written as 11/4. Next, divide -21/4 by 11/4. To divide fractions, multiply the first fraction by the reciprocal of the second fraction. So, (-21/4) * (4/11) = -21/11. This quotient can be written in mixed number form as -1 10/11, which is the simplified answer.

Determine the unit rate. Use mental math when you can. 6 golf balls for $15. 2 dozen tennis balls for $36. 4lb meat for $18. 24 tickets for $480.
To determine the unit rate for each item, divide the total cost by the number of units. This gives us $2.50 per golf ball, $1.50 per tennis ball, $4.50 per pound of meat, and $20 per ticket.
Explanation:The question involves determining the unit rate of different items. A unit rate is the cost per one unit of an item. To calculate each unit rate, we divide the total cost by the number of units.
For 6 golf balls for $15, the unit rate is $15 ÷ 6 = $2.50 per golf ball.For 2 dozen (24) tennis balls for $36, the unit rate is $36 ÷ 24 = $1.50 per tennis ball.For 4lb of meat for $18, the unit rate is $18 ÷ 4 = $4.50 per pound of meat.For 24 tickets for $480, the unit rate is $480 ÷ 24 = $20 per ticket.These calculations can often be made using mental math, especially when dealing with simple numbers or common multiples.

What is the largest flag jake can draw
In the painting 'Three Flags' by Jasper Johns, the size of the largest flag would depend on the canvas or surface used.
Explanation:In the painting Three Flags by Jasper Johns, he used his encaustic process to create the artwork. Each flag reduced about twenty-five percent in scale as he stacked canvas flags, with the largest one receding into the background. The congealed wax drippings gave the painting a dimensional sculptural appearance.
The stripes and stars on the flags also grow smaller, adding to the illusion of three separate elements. Therefore, in terms of the largest flag Jake can draw, it would depend on the size of the canvas or surface that he is working with.
The fracture toughness (in ) of a particular steel alloy is known to be normally distributed with a mean of 28.3 and a standard deviation of 0.77. We select one sample of this alloy at random and measure its fracture toughness. Given that the fracture toughness is at least 27, what is the probability that the fracture toughness will be between 29 and 40.3? is it just P(X <= 40.3) - P(X <= 29)? How do I use the 27?
At one university, the students are given z-scores at the end of the each semester, rather than the traditional gpas. the mean and standard deviation of all students' cumulative gpas, on which the z-scores are based, are 2.7 and 0.5, respectively
The students with z-scores below -1.6 would be put on probation, and the corresponding probationary GPA is 1.9.
Given data:
To translate z-scores to corresponding GPAs, you can use the formula:
GPA = (z * standard deviation) + mean
Given:
Mean (μ) = 2.7
Standard Deviation (σ) = 0.5
Let's calculate the corresponding GPAs for the given z-scores:
For z = 2.0:
GPA = (2.0 * 0.5) + 2.7
= 1.0 + 2.7
= 3.7
For z = -1.0:
GPA = (-1.0 * 0.5) + 2.7
= -0.5 + 2.7
= 2.2
For z = 0.5:
GPA = (0.5 * 0.5) + 2.7
= 0.25 + 2.7
= 2.95
For z = -2.5:
GPA = (-2.5 * 0.5) + 2.7
= -1.25 + 2.7
= 1.45
Now, to determine the corresponding probationary GPA for z = -1.6:
GPA = (-1.6 * 0.5) + 2.7
= -0.8 + 2.7
= 1.9
Hence, students with z-scores below -1.6 would be put on probation, and the corresponding probationary GPA is approximately 1.9.

what is absolute value of these set of numbers?
The time required to cook a pizza at a neighborhood pizza joint is normally distributed with a mean of 12 minutes and a standard deviation of 2 minutes. find the time for each event. (round your answers to 2 decimal places.)
a. highest 5 percent min.
b. lowest 50 percent min.
c. middle 95 percent min. to min.
d. lowest 80 percent min.
a. The highest 5 percent time is approximately 15.29 minutes. b. The lowest 50 percent time is 12 minutes. c. The middle 95 percent interval is approximately 8.08 minutes to 15.92 minutes. d. The lowest 80 percent time is approximately 10.32 minutes.
Explanation:a. To find the highest 5 percent, we need to find the value that separates the highest 5 percent from the rest. This value is called the upper 5th percentile. Using the z-score formula, z = (x - mean) / standard deviation, we can find the z-score associated with the upper 5th percentile. By looking up this z-score in the z-table, we can find the corresponding value. In this case, the z-score is approximately 1.645. Using the formula, x = z * standard deviation + mean, we can calculate the time needed for the highest 5 percent: x = 1.645 * 2 + 12 = 15.29 minutes.
b. To find the lowest 50 percent, we need to find the value that separates the lowest 50 percent from the rest. This value is called the median. The median of a normally distributed data set is equal to the mean. Hence, the lowest 50 percent time is the mean of 12 minutes.
c. To find the time for the middle 95 percent interval, we need to find the values that separate the middle 95 percent from the rest. These values are called the lower 2.5th percentile and the upper 2.5th percentile. Using the z-score formula, we can find the z-scores associated with the lower and upper 2.5th percentiles. By looking up these z-scores in the z-table, we can find the corresponding values. In this case, the z-scores are approximately -1.960 and 1.960. Using the formula, x = z * standard deviation + mean, we can calculate the times: lower 2.5th percentile = -1.960 * 2 + 12 = 8.08 minutes, and upper 2.5th percentile = 1.960 * 2 + 12 = 15.92 minutes.
d. To find the lowest 80 percent, we need to find the value that separates the lowest 80 percent from the rest. This value is called the lower 20th percentile. Using the z-score formula, we can find the z-score associated with the lower 20th percentile. By looking up this z-score in the z-table, we can find the corresponding value. In this case, the z-score is approximately -0.841. Using the formula, x = z * standard deviation + mean, we can calculate the time needed for the lowest 80 percent: x = -0.841 * 2 + 12 = 10.32 minutes.
use the multiplication table. describe a pattern you see, 5, 10, 15
Final answer:
The sequence 5, 10, 15 represents multiples of 5, where each number is 5 units apart from the last.
This pattern can also be observed in a multiplication table in the row or column of the number 5.
Explanation:
The question asks us to describe a pattern in the sequence 5, 10, 15.
This sequence represents the multiples of 5. A clear pattern that can be observed is that each number increases by 5 to get to the next multiple.
For instance, starting with 5, adding 5 gives us 10, and adding another 5 to 10 gives us 15.
This pattern continues indefinitely with the series 20, 25, 30, and so on.

How do you write .625 as a fraction
To turn a decimal into a fraction, first notice that the number to the right of the decimal point is 625. The 6 represents the tens, the 2 represents the hundreds, and the 5 represents the thousands. So, we can put 625 over 1000 or 625/1000.
Notice that the fraction [tex]\frac{625}{1000}[/tex] is not in lowest terms. To turn the fraction into lowest terms, we can divide both the numerator and the denominator by 125.
[tex]\frac{625}{1000}[/tex] ÷ [tex]\frac{125}{125}[/tex] = [tex]\frac{5}{8}[/tex]
Therefore, .625 can be written as the fraction 5/8, which is in lowest terms.
5y-x=10 (solve for y).
To solve 5y - x = 10 for y, add x to both sides and then divide by 5, resulting in the solution y = (x + 10) / 5.
To solve the equation 5y - x = 10 for y, follow these steps:
Add x to both sides of the equation to isolate terms with y on one side: 5y = x + 10.
Now, divide both sides of the equation by 5 to solve for y:
y = (x + 10) / 5.
The solution for y when given an equation of the form 5y - x = 10 is y = (x + 10) / 5.

Is his model correct? Expalin
To determine a 72 percent level of confidence for a proportion, the value of z is approximately:
To solve this problem, we have to make use of the standard probability distribution tables for z test.
Since we are asked to find for the 72 percent level confidence, then this means we are to look for the value of z which gives (100-72)/2 = 14% on both sides of the tail.
So at 14% tail on one side, the z value is approximately:
