The complete equation is 3 lb/sec ≈ 4897.0806 kg/h.
How to complete the conversionFrom the question, we have the following parameters that can be used in our computation:
3 Ib/sec ≈ ? kg/h
To convert pounds per second (lb/sec) to kilograms per hour (kg/h), we can use the conversion factor: 1 lb = 0.45359237 kg.
So, 3 lb/sec = 3 * 0.45359237 kg/sec = 1.361 kg/sec
To convert from per second to per hour, we multiply by the number of seconds per hour:
1.3607771 kg/sec * 3600 sec/hour = 4897.0806 kg/h
Therefore, 3 lb/sec ≈ 4897.0806 kg/h.

to estimate the mean score of those who took the medical college admissions test on your campus you obtain an srs of students. how large of an srs must you take
The size of a Simple Random Sample (SRS) for estimating the mean score of medical college admissions test takers on your campus depends on the desired level of precision and the variability of the population.
The sample size required to estimate the mean score of a population depends on the desired level of precision, the variability of the population, and the level of confidence desired. In general, a larger sample size is needed to estimate the mean of a population with high variability or when a high level of precision is desired.
On the other hand, a smaller sample size is sufficient if the population is relatively homogeneous or if a lower level of precision is acceptable. It's important to note that a sample size that is too small may result in an imprecise estimate, while a sample size that is too large may be unnecessarily wasteful. A statistician can help determine the appropriate sample size for a given situation.

It is Tyler's first season playing baseball with the Diamondbacks. He has had 383 at-bats. So far, he has 74 singles, 13 doubles, 11 triples and 4 homeruns. What is Tyler's current Slugging Percentage? What is Tyler's Batting Average?
a. To calculate the average daily sales over the course of seven days, multiply the total sales over the course of seven days by seven.
a. How much did they sell on average per day over the entire 7 days?The salesperson generated $36,000 in revenue in the first three days by selling an average of $12,000 per day.
The following four days saw sales of $9,000 on average, for a total of $36,000 ($4 days * $9,000/day). Sales for the seven days added up to $36,000 + $36,000 = $72,000. Thus, throughout the course of the entire seven days, the average daily sales were $72,000 / seven days, or $10,285.7.
b. How much does she make on average per hour for the day?b. We must aggregate the total earnings from both jobs and divide it by the total number of hours worked in order to determine the average hourly wage. Kelly puts in a total of 12 hours of work by working 5 hours at a restaurant and 7 hours at a retail store. She is paid $12 per hour at the retail location and $20 per hour at the restaurant, so her total pay for seven hours is $104. The daily average hourly wage is $104 divided by 12 hours, or $8.67.
c. How much did he earn on the last day?c. We must first calculate Henry's total earnings for the first 10 days, then deduct those earnings from the first 9 days to arrive at his earnings on the final day. The total income for the first 10 days was $1,200 (10 days * $120/day). Five days at a rate of $100 each brought in a total of $500. The next four days' earnings came to $520 (4 days * $130/day). For the first nine days, the total earnings were $500 + $520, or $1,020. Therefore, Henry's final day earnings were $180 ($1,200 – $1,020).
d. How many at-bats has Marcus had?d. The number of singles, doubles, triples, and home runs must be added up in order to determine the total number of at-bats. Marcus has 107 hits overall, which include 18 singles, 33 doubles, 2 triples, and 54 home homers. He has now played in 107 at-bats.
e.. What is Tyler's current Slugging Percentage? What is Tyler's Batting Average?e. The total bases (one base for a single, two bases for a double, three bases for a triple, and four bases for a home run) must be added together and divided by the total at-bats in order to determine the slugging percentage. Tyler has 235 total bases, which are calculated as follows: 74 singles * 1 base/single + 13 doubles * 2 bases/double + 11 triples * 3 bases/triple + 4 home runs * 4 bases/home run. His Slugging Percentage therefore equals 235 / 383 at-bats, or 0.616. Divide the total number of hits by the total number of at-bats to obtain the batting average. 383 at-bats x 74 hits Equals 0.193 for Tyler.

what is the solution to this system of equations
Answer:
[tex](-1, -2)[/tex]
Step-by-step explanation:
In this problem, we are asked to solve a system of equations given two equations each containing two variables: x and y. We can solve it using the substitution method.
First, we need to solve for a variable in terms of the other using one of the equations. I will solve for x in the first equation.
[tex]4x-7y=10[/tex]
↓ add [tex]7y[/tex] to both sides
[tex]4x=7y+10[/tex]
↓ divide both sides by 4
[tex]x=\dfrac{7y+10}{4}[/tex]
Now that we have solved for x in terms of y, we can substitute the solved x-value into the bottom equation.
[tex]3x + 2y = -7[/tex]
↓ substitute in solved x-value
[tex]3\left(\dfrac{7y+10}{4}\right) + 2y = -7[/tex]
↓ distribute 3
[tex]\dfrac{21y+30}{4}\right) + 2y\left(\dfrac{4}{4}\right) = -7\left(\dfrac{4}{4}\right)[/tex]
↓ rewrite all terms as fractions over 4
[tex]\dfrac{21y+30 + 8y}{4}\right)= -\dfrac{28}{4}[/tex]
↓ cancel denominators
[tex]29y+30= -28[/tex]
↓ isolate y's
[tex]29y = -28 - 30[/tex]
↓ simplify
[tex]29y= -58[/tex]
↓ divide both sides by 29
[tex]y = -2[/tex]
Now that we have solved exactly for y, we can solve for x using the substitution value we solved for earlier.
[tex]x=\dfrac{7y+10}{4}[/tex]
↓ substitute in y-value
[tex]x=\dfrac{7(-2)+10}{4}[/tex]
↓ simplify numerator
[tex]x=\dfrac{-14+10}{4}[/tex]
[tex]x=\dfrac{-4}{4}[/tex]
[tex]x = -1[/tex]
Finally, we can put the solved x and y values into a Cartesian coordinate in the form (x, y).

find the open intervals over which the function is increasing or decreasing. write the answers in interval notation.
Given a quadratic function y = 36 - x² , the intervals over which the function is increasing is: (-∞ , 0) and the intervals over which the function is decreasing is: (0, ∞).
The standard form of a quadratic function is given by:
f(x) = ax² + bx + c
If a > 0, the graph of the function opens upward and the extreme point is the minimum one.
If a < 0, the graph of the function opens downward and the extreme point is the maximum one.
In this case, the function is: y = 36 - x²
Since the coefficient of the quadratic term is negative, or a < 0, then the graph opens downward and has a maximum point.
y = 36 - x² is already in the form of perfect square, hence, we can immediately compute:
x-intercepts : (-6,0) and (6,0)
y-(intercept = maximum point = (0, 36)
Before the maximum point, the function is increasing, while after the maximum point, the function is decreasing.
Hence,
increasing interval = (-∞ , 0)
decreasing interval = (0, ∞)
