The number of calories by a 37-member platoon of soldiers will be 6,48,24000 calories.
What are calories?A calorie is a unit of energy. Energy is defined as the capacity to do work.
Now it is given that,
Calories contain in 1 MRE = 1,600
Number of MREs taken by a soldier per day = 3
Therefore, number of calories taken by soldier per day = 3*1600
= 4800 calories
Therefore, number of calories taken by 37 soldier per day = 37*4800
= 1,77,600 calories
Now since, 12 months = 365 days
⇒Number of calories taken by 37 soldier in 12 months = 365*1,77,600
⇒Number of calories taken by 37 soldier in 12 months =6,48,24000 calories.
Hence,The number of calories by a 37-member platoon of soldiers will be 6,48,24000 calories.

Answer:
This answer is 8
Step-by-step explanation:
It actually is very simple. For this question you do not even need the g(x) equation to continue, so put it aside for now. F(x) means that whatever number that will take the place of x will be used in this equation. If f(x)=3x-1, then f(3)=3(3)-1
This happens because the 3 in f(3 tells you to substitute x for 3 in the equation. ) So just plug in 3 for x and solve to get the answer 8.

Solve for C: S = C+RC
Answer:
factoring c is the best way to solve this
Step-by-step explanation:
S = C ( 1 + R )
C = S/( 1 + R )
The equation after solving is C = S / (1 + R).
To solve for C in the equation S = C + RC, we can factor out C on the right side:
S = C + RC
S = C(1 + R)
Then, we can divide both sides by (1 + R) to isolate C:
S / (1 + R) = C
Therefore, the solution is:
C = S / (1 + R)
For example, if S = 100 and R = 0.1, then C would be:
C = 100 / (1 + 0.1)
C = 100 / 1.1
C = 90.9090909090909

A student has these scores on their assignments. The teacher is considering dropping a
lowest score.
0, 40, 60, 70, 75, 80, 85, 95, 95, 100
a) What effect does eliminating the lowest value, 0, from the data set have on the mean
and median?
b) Would there be more of a significant change on the IQR or Standard Deviation?
Explain why.
The answers are shown below:
What is mean and median?The arithmetic mean of a given data is the sum of all observations divided by the number of observations. For example, a cricketer's scores in five ODI matches are as follows: 12, 34, 45, 50, 24. To find his average score in a match, we calculate the arithmetic mean of data using the mean formula:
Mean = Sum of all observations/Number of observations
Mean = Sum of all observations/Number of observations
Mean = (12 + 34 + 45 + 50 + 24)/5
Mean = 165/5 = 33
The value of the middlemost observation, obtained after arranging the data in ascending or descending order, is called the median of the data.
For example, consider the data: 4, 4, 6, 3, 2. Let's arrange this data in ascending order: 2, 3, 4, 4, 6. There are 5 observations. Thus, median = middle value i.e. 4.
Given data:
0, 40, 60, 70, 75, 80, 85, 95, 95, 100
a)Mean without '0' = 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100/9
= 700/9
= 77.777
Median without '0' = 80
Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100/10 = 70
Median with '0' = 80
b)standard deviation= 18.121673811445. (without '0')
standard deviation with 0 = 28.982753492379

Car weight
(b) Does the scatterplot show a positive association, negative association, or neither? Explain why this
makes sense.
(c) How would you describe the form of the relationship?
(d) Which of the following is closest to the correlation between car weight and fuel efficiency for these
20 vehicles? Explain.
r=-0.9
r=-0.6
r=0 r=0.4
(e) There is one "unusual point" on the graph. Explain what is "unusual" about this car.
(
What effect would removing the “unusual point” have on the correlation? Justify your answer.
(g) If we converted the car weights to metric tons (1 metric ton -2,205 pounds). How would the
correlation change? Explain.
The explanatory variable is the car's weight, with fuel efficiency as the response variable; a likely negative association may exist, possibly linear or non-linear; a correlation like r=-0.9 or r=-0.6 is plausible; an 'unusual point' could be an outlier affecting the correlation; removing it might strengthen or weaken the correlation; converting weights to metric tons wouldn't alter the correlation.
(a) In this context, the explanatory variable is the car's weight (in pounds) and the fuel efficiency (in miles per gallon) is the response variable. This is because we are typically interested in determining the effect of a car's weight on its fuel efficiency.
(b) Based on the context, a scatterplot might show a negative association between the car's weight and its fuel efficiency. This would make sense as heavier cars often require more fuel to operate efficiently, leading to lower miles per gallon.
(c) The form of the relationship between car weight and fuel efficiency can vary. For instance, it could be linear (indicating a constant rate of change) or non-linear (indicating a rate of change that varies with weight).
(d) Without viewing the scatterplot it's not possible to definitively answer this, but based on the proposed negative relationship, a correlation of r=-0.9 or r=-0.6 would be plausible. Correlations range from -1 to 1, and a negative sign indicates an inverse relationship.
(e) An 'unusual point’ could be an outlier on the scatterplot that doesn't model the relationship between car weight and fuel efficiency like the rest of the data. This could be due to factors unique to this car, such as a highly efficient engine that gets more miles per gallon despite its weight
(f) Depending on the unique characteristics of the 'unusual point', its removal could either increase or decrease the correlation. If this point were causing the correlation to be weaker, its removal would cause the correlation to strengthen, and vice-versa.
(g) Converting the car weights to metric tons wouldn't change the correlation between weight and fuel efficiency. Correlation is unitless and depends only on the relationship between variables, not the scale they're measured on. Thus, while the specific values for weight would change, the strength, direction, and form of the relationship between weight and fuel efficiency would remain the same.

Can you draw two triangles each having two 45° angles and one. 90° angle that are not similar justify her answer
No, you cannot draw two triangles each having two 45° angles and one 90° angle that are not similar. All 45-45-90 triangles are similar by definition because they have the same shape, i.e., their angles are the same (two 45° angles and one 90° angle). These similar figures can differ in size, but not in shape.
Explanation:No, it is not possible to draw two triangles each having two 45° angles and one 90° angle that are not similar. Let's break this down.
All triangles that have two 45° angles and one 90° angle are called 45-45-90 triangles. In a 45-45-90 triangle, the angles are always the same, so they are always similar by the definition of similar figures. Similar figures have the same shape, but not necessarily the same size. Their corresponding angles are congruent (the same) and their corresponding sides are in proportion.
Since all 45-45-90 triangles have the same angles - two 45° angles and one 90° angle - they are all similar to each other, regardless of their size. The size of the triangle does not matter, because the definition of similar figures is based on the shape, not the size. Hence, it is impossible to draw two 45-45-90 triangles that are not similar.

263 grams dental stone powder
80 milliliters of water
If you use 70 grams of stone, how many milliliters of water are needed?
Answer:
21.29 milliliters
Step-by-step explanation:
First find how much water is need for 1 gram of stone by dividing both numbers by 263. Then multiplying both numbers by 70.
Grams : Milliliters
263 80
1 : 0.3042 (Rounded to 4 decimal places)
70 : 21.29 (Rounded to 2 decimal places)
The amount of water needed when using 70 grams of dental stone powder is approximately 21.29 milliliters. This is based on the ratio of stone powder to water in the original mixture.
Explanation:The question is asking for the calculation of the amount of water needed if 70 grams of dental stone powder is used. This can be resolved by determining the ratio of water to dental stone powder in the initial mixture, and then applying this ratio to the lesser quantity of 70 grams. In the original mixture, there are 263 grams of dental stone powder to 80 milliliters of water which simplifies to approximately 1 gram to 0.3042 milliliters of water. Therefore, if you use 70 grams of stone powder, you multiply 70 grams by 0.3042 milliliters/g, which equates to approximately 21.29 milliliters of water.
