Answers
By using the unitary method in linear equation, the answer is 925.
We have a factory that makes 400 refrigerators every day and makes 125 more stoves per day than refrigerators is as follows:
Let's use the unitary method in linear equation to solve this problem. We can use the following equation to find x, the total number of refrigerators and stoves the factory makes in one day:
X = 400 (number of refrigerators) + (400 + 125) (number of stoves)
X = 400 + 525
X = 925
Therefore, the factory makes 925 refrigerators and stoves every day.

Tallulah needs to order some new supplies for the restaurant where she works. the restaurant needs at least 569 glasses. there are currently 245 glasses. if each set on sale contains 10 glasses, write and solve an inequality which can be used to determine ss, the number of sets of glasses tallulah could buy for the restaurant to have enough glasses.
Answers
Tallulah needs to buy at least 33 sets of glasses, where each set has 10 glasses, to ensure the restaurant has at least 569 glasses. The inequality is 10s ≥ 324, solved as s ≥ 33.
Let's use "s" to represent the number of sets of glasses Tallulah could buy. Since each set contains 10 glasses, the total number of glasses she would purchase is 10s.
The restaurant needs at least 569 glasses, and currently has 245 glasses. Therefore, Tallulah needs to buy enough glasses to make up the difference:
569 - 245 = 324
To ensure that the restaurant has at least 569 glasses after Tallulah makes her purchase, we can set up the inequality:
10s ≥ 324
Solving for "s", we can divide both sides by 10:
s ≥ 32.4
Since Tallulah cannot buy a fraction of a set, we need to round up to the nearest whole number. Therefore, she must buy at least 33 sets of glasses to have enough for the restaurant.
So the final inequality and solution is:
10s ≥ 324
s ≥ 32.4
s ≥ 33 (rounded up to the nearest whole number)

On January 1st, 2017, your great uncle creates an account in your name and invests $20,000 in treasury bills. The nominal rate on the T-bills is 1.95% compounded every 73 days. Exactly 6 months later, your mother deposits $10,000 into an investment account, compounding continuously at 4% per year. What is the combined value of these two accounts on January 1st, 2019 ?
Answers
The combined value of the two accounts on January 1st, 2019, is approximately $31,642.05.
To solve this problem, we'll calculate the value of each investment separately and then combine them.
First, let's calculate the value of your great uncle's investment in treasury bills. The nominal rate of 1.95% compounded every 73 days can be converted to an effective rate per year using the formula:
Effective rate = (1 + (nominal rate / m)) ^ m - 1
Where "m" is the number of compounding periods per year. In this case, there are approximately 365 days in a year, so the number of compounding periods is:
m = 365 / 73 = 5
Effective rate = (1 + (0.0195 / 5)) ^ 5 - 1 = 0.0200
Now, let's calculate the value of the treasury bills investment after 2 years (from January 1st, 2017, to January 1st, 2019):
Value of treasury bills = $20,000 * (1 + 0.0200)^(2 * 365/73) = $20,000 * (1.0200)^(10) ≈ $20,825.40
Next, let's calculate the value of your mother's investment, which is compounding continuously at a rate of 4% per year:
Value of mother's investment = $10,000 * e^(0.04 * 2) ≈ $10,816.65
Finally, let's calculate the combined value of these two accounts:
Combined value = Value of treasury bills + Value of mother's investment
= $20,825.40 + $10,816.65 ≈ $31,642.05
Therefore, the combined value of the two accounts on January 1st, 2019, is approximately $31,642.05.

compared to small samples, large samples have ___________ variability and thus will have a ___________ error from the population parameters.
Answers
Compared to small samples, large samples have less variability and thus will have a smaller error from the population parameters. Variability refers to the degree to which the data points in a sample differ from one another.
A small sample size may not accurately represent the population it was taken from, as it is subject to random variation. This random variation may lead to a large degree of variability in the sample, which in turn leads to a larger error from the population parameters.
On the other hand, large samples tend to have a more representative selection of individuals from the population. As a result, they tend to have less variability and a smaller error from the population parameters. This means that the estimates made from a large sample are likely to be more accurate than those made from a small sample. However, it is important to note that even with a large sample size, there may still be some degree of error due to other factors such as sampling bias or measurement error. Therefore, it is important to carefully consider the sample size and other factors when making statistical inferences about a population.
Compared to small samples, large samples have lower variability and thus will have a smaller error from the population parameters.
To explain further, a "sample" is a subset of a larger group, called the "population." When conducting research or analyzing data, researchers use samples to make inferences about the overall population. The characteristics of the population, such as the mean and standard deviation, are called "parameters."
When a sample is small, it is more susceptible to variability, which is the degree to which the data points in the sample differ from one another. High variability can lead to unreliable conclusions about the population parameters. A small sample may not be representative of the entire population, so the error, or difference between the sample estimate and the actual population parameter, can be larger.
On the other hand, large samples tend to have lower variability because they include more data points from the population, making them more representative of the overall group. This increased representation leads to a smaller error between the sample estimate and the actual population parameter.
In summary, using large samples is generally more advantageous because they provide lower variability and smaller errors, leading to more accurate estimates of population parameters.

Describe the difference between the graphs you made by the Man walking slowly and those made by the Man walking more quickly
Answers
The graphs for the man walking slowly and walking quickly differ in various ways. Graphs are graphical representations of data that display how two variables relate to each other. Time is plotted on the x-axis, whereas the distance travelled by the man is plotted on the y-axis. A line graph is used to plot the data in each case.
The following are the differences between the graphs for the man walking slowly and quickly: Graphs for a man walking slowly: When the man walks slowly, the slope of the line graph is relatively gentle. In a given time interval, the man walks a shorter distance. As a result, the graph's slope will be less steep. The graph's slope increases as the man's pace slows down. Graphs for a man walking quickly:
When the man walks quickly, the slope of the line graph is steep. The man will walk a more extended distance in the same amount of time. As a result, the graph's slope will be more significant. The graph's slope will decrease as the man's pace increases.Based on the above information, we can conclude that the slope of the graph depends on how quickly or slowly the man walks. Therefore, the graphs for the man walking slowly and quickly differ in slope.

Answers
=================================================
Explanation:
LA stands for Leg Angle. More specifically, the angle is an acute angle. This theorem only works for right triangles. We see that ED = LK which is one pair of congruent leg segments. So that takes care of the L part of LA. However, we don't know anything about the acute angles. We don't know if angle E = angle L, or if angle F = angle M, or something along those lines. We need angle markers to tell us or not.
In short, we only have half the info needed for LA, so we must cross choice A off the list.
----------------
HA stands for hypotenuse angle, or hypotenuse acute angle, and this rule only applies for right triangles. We don't know anything about the hypotenuse lengths if they are the same or not.
Similar to choice A, we don't know anything about the acute angles either.
Those two facts mean we must cross off choice B.
----------------
AAS stands for Angle Angle Side. The order is important because the side is not between the angles. The diagram only shows one pair of angles that are congruent to one another. That pair being the 90 degree angles indicated with the square marker. We don't have another pair of angles, so we cannot use AAS.
Cross choice C off the list.
-----------------
We can use SAS because we have two pairs of congruent sides and one pair of congruent angles.
The congruent sides are
ED = LK (double tickmarks)DF = KM (single tickmarks)That takes care of the two "S"s of "SAS". The "A" would be those two right angles which are congruent to one another. The angles are between the congruent sides which is important. Recall that SSA is not a valid congruence theorem.
So that's why choice D is the only answer.
-----------------
Side note: We could use the LL theorem, where L stands for leg, since we are given two pairs of congruent legs for each triangle. Like LA and HA, this only applies to right triangles. LL is a special case of SAS. However, LL isn't listed so we'll just be sticking with SAS as the only answer.
