At a basketball game, a team made 51 successful shots. They were a combination of 1- and
2-point shots. The team scored 83 points in all. Write and solve a system of equations to find the
number of each type of shot.
There were 2-point shots and 1-point shots.
Answers
Answer:
19 1-point shots and 32 2-point shots
Step-by-step explanation:
Let x be the amount of 1-point shots they made and y be the amount of 2-point shots they made then...
x+y=51
x+2y=83
We can solve this equation using elimination. In this case, we can eliminate x be subtracting the two equations.
-y=-32
Divide both sides by -1
y=32
Plug this back into the equation to solve for x
x+32=51
Subtract 32 from both sides
x=19
They scored 19 1-point shots and 32 2-point shots.

A friend of ours takes the bus five days per week to her job. The five waiting times until she can board the bus are a random sample from a uniform distribution on the interval from 0 to 10 min. Determine the pdf and then the expected value of the largest of the five waiting times.
Answers
The probability density function (pdf) of the largest of the five waiting times is given by: f(x) = 4/10^5 * x^4, where x is a real number between 0 and 10. The expected value of the largest of the five waiting times is 8.33 minutes.
The pdf of the largest of the five waiting times can be found by considering the order statistics of the waiting times. The order statistics are the values of the waiting times sorted from smallest to largest.
In this case, the order statistics are X1, X2, X3, X4, and X5. The largest of the five waiting times is X5.
The pdf of X5 can be found by considering the cumulative distribution function (cdf) of X5. The cdf of X5 is given by: F(x) = (x/10)^5
where x is a real number between 0 and 10. The pdf of X5 can be found by differentiating the cdf of X5. This gives: f(x) = 4/10^5 * x^4
The expected value of X5 can be found by integrating the pdf of X5 from 0 to 10. This gives: E[X5] = ∫_0^10 4/10^5 * x^4 dx = 8.33

Hi! I would like to ask for some help please, thank you! (Indirect Variation)1. Y is inversely proportional to the square of x. When y = 3, x = 2Find the value of y when x = 4.2. Y is inversely proportional to the square root of x. When y = 10, x = 4.Find the Value of y when x = 25.3. Y is inversely proportional to the cube of x. When y = 18, x = 3.Find the value of y when x = 6.
Answers
1. Given that y is inversely proportional to the square of x, we can express this relationship as \(\(y = \frac{k}{{x^2}}\)\), where k is the constant of proportionality. When y = 3 and x = 2, we can substitute these values into the equation to find k:
\(\[3 = \frac{k}{{2^2}}\]\)
\(\[3 = \frac{k}{4}\]\)
\(\[k = 12\]\)
Now, we can find the value of (y) when (x = 4):
\(\[y = \frac{12}{{4^2}}\]\)
\(\[y = \frac{12}{16}\]\)
\(y = 0.75\)
Therefore, when (x = 4), the value of y is 0.75.
2. In this case, \(\(y\)\) is inversely proportional to the square root of \(\(x\)\), so we have \(\(y = \frac{k}{{\sqrt{x}}}\)\). When \(\(y = 10\)\) and \(\(x = 4\)\), we can substitute these values into the equation to find \(\(k\)\):
\(\[10 = \frac{k}{{\sqrt{4}}}\]\)
\(\[10 = \frac{k}{2}\]\)
\(\[k = 20\]\)
Using the value of \(\(k\)\), we can find \(\(y\)\) when \(\(x = 25\)\):
\(\[y = \frac{20}{{\sqrt{25}}}\]\)
\(\[y = \frac{20}{5}\]\)
\(\[y = 4\]\)
Therefore, when \(\(x = 25\)\), the value of \(\(y\)\) is 4.
3. In this scenario, \(\(y\)\) is inversely proportional to the cube of \(\(x\)\), so we have \(\(y = \frac{k}{{x^3}}\)\). When \(\(y = 18\)\) and \(\(x = 3\)\), we can substitute these values into the equation to find \(\(k\)\):
\(\[18 = \frac{k}{{3^3}}\]\)
\(\[18 = \frac{k}{27}\]\)
\(\[k = 486\]\)
Using the value of \(\(k\)\), we can find \(\(y\)\) when \(\(x = 6\)\):
\(\[y = \frac{486}{{6^3}}\]\)
\(\[y = \frac{486}{216}\]\)
\(\[y = 2.25\]\)
Hence, when \(\(x = 6\)\), the value of \(\(y\)\) is 2.25.

What is the difference between continuous and differentiable in calculus?
Answers
The key difference between continuous and differentiable functions is that a function can be continuous without being differentiable, but a function cannot be differentiable unless it is continuous.
In calculus, a function is supposed to be continuous in the event that there are no unexpected leaps or breaks in its chart. This truly intends that as the values of the free factor (normally meant as x) move toward a given point, the values of the dependent variable (generally indicated as y) likewise approach a comparing esteem with next to no unexpected jumps or gaps.
On the other hand, a function is supposed to be differentiable in the event that it has an obvious derivative at each point in its space. The derivative of a capability portrays how the capability changes for little changes in the free factor. A function is differentiable assuming it has a tangent line at each point in its space, and that implies that the capability is smooth and has no sharp turns or corners.

The lender made a fairly good estimate; it was between 0. 25% and 0. 5% of the actual closing costs. D. The lender made a poor estimate; it was off by more than 0. 5% of the actual closing costs. Please select the best answer from the choices provided A B C D.
Answers
Based on the given data, the main answer is that the lender made a poor estimate because it was off by more than 0.5% of the actual closing costs.
The closing cost charge has been calculated using the given formula, the result is 4,500. That is the estimated closing cost for the loan. The actual closing costs of the loan were $4,350. So, we will now calculate the difference between the estimated closing costs and the actual closing costs:Estimated closing costs - Actual closing costs = 4,500 - 4,350 = $150The difference between the estimated and the actual closing cost is $150. Now, we will calculate the percent error.Percent error = |Estimated value - Actual value| / Actual value × 100%Putting the given values in the formula, we get:Percent error = |150| / 4,350 × 100%Percent error = 3.45%According to the options given in the question, option D is the correct answer, which says that the lender made a poor estimate because it was off by more than 0.5% of the actual closing costs.
The difference between the estimated closing cost and the actual closing cost is $150, and the percent error is 3.45%. According to the given options, the lender made a poor estimate because it was off by more than 0.5% of the actual closing costs.

that means combinations :
C(13, 3) = 13! / (3! × (13 - 3)!) = 13! /(3! × 10!) =
= 13×12×11 / (3×2) = 13×2×11 = 286
there can be 286 different random samples of size 3.
The answer is 286.
The number of different simple random samples of size 3 that can be selected from a population consisting of 13 items is 286.Explanation:Simple random sampling is a statistical technique used in research. In this sampling method, a subset of a population is selected randomly, with each member of the population having an equal chance of being selected. There are different types of random sampling methods, such as systematic sampling, stratified sampling, cluster sampling, etc.The number of different simple random samples of size k that can be selected from a population of size N is given by the formula N!/k!(N-k)!, where ! denotes factorial. Here, the population consists of 13 items, and we need to find the number of different simple random samples of size 3 that can be selected from this population.So, the required number of different simple random samples of size 3 that can be selected from this population is 13!/3!(13-3)! = 286.
Therefore, the number of different simple random samples of size 3 that can be selected from a population consisting of 13 items is 286.

alice refuses to sit next to either bob or carla. derek refuses to sit next to eric. how many ways are there for the five of them to sit in a row of chairs under these conditions?
Answers
The total number of ways five of them to sit in a row of chairs under the given condition is equal to 152 ways.
Use the principle of inclusion-exclusion to solve this problem.
Let us first consider the case where Alice sits next to Bob or Carla.
Now, treat Alice, Bob, and Carla as a block, which can be arranged in 3! = 6 ways.
Within this block, Alice can sit in two different positions,
And Bob and Carla can sit in the remaining two positions.
There are 6 x 2 = 12 ways for Alice to sit next to Bob or Carla.
Now,
Let us consider the case where Derek sits next to Eric.
Treat Derek and Eric as a block,
which can be arranged in 2! = 2 ways.
Within this block,
Derek can sit in two different positions,
And Eric can sit in the remaining position.
There are 2 x 2 = 4 ways for Derek to sit next to Eric.
However,
Double-counted the case where Alice sits next to Bob or Carla AND Derek sits next to Eric.
Treat Alice, Bob, Carla, Derek, and Eric as two blocks,
which can be arranged in 2! x 3! = 12 ways.
Within each block,
There are 2 ways to arrange the people.
There are 12 x 2 x 2 = 48 ways for both conditions to be satisfied.
Using the principle of inclusion-exclusion,
The total number of ways for the five of them to sit in a row of chairs under these conditions.
Total
= total number of ways - number of ways Alice sits next to Bob or Carla - number of ways Derek sits next to Eric + number of ways both conditions are satisfied
= 5! - 12 - 4 + 48
= 152
Therefore, there are 152 ways for the five of them to sit in a row of chairs under these conditions.

This graph suggests that the greater the rainfall in June through August, the fewer acres are burned by wildfires. Which factor in the graph supports this idea?
Answers
The factor in the graph that supports the idea that the greater the rainfall in June through August, the fewer acres are burned by wildfires is the negative correlation between rainfall and acres burned.
The graph shows a negative correlation between the amount of rainfall in June through August and the number of acres burned by wildfires. As the amount of rainfall increases, the number of acres burned decreases. This suggests that wetter weather can help reduce the risk of wildfires.
The graph provides a visual representation of the relationship between rainfall and wildfires. It shows that there is a clear negative correlation between the two variables. This means that as one variable increases, the other decreases. In this case, the variable of interest is the number of acres burned by wildfires. The graph shows that when there is less rainfall in June through August, more acres are burned by wildfires. Conversely, when there is more rainfall during these months, fewer acres are burned. This makes sense because rainfall can help reduce the risk of wildfires by making vegetation less dry and therefore less susceptible to catching fire. Additionally, wetter weather can help firefighters contain and extinguish fires more quickly and effectively.
