Let X be the number of accidents per weck in a factory. Let the probability mass function of X bc P(X=x)=x+11−x+21,x=0,1,2,3,… Find the conditional probability of X≥3 given that X>0.
Answers
The conditional probability of X≥3 given that X>0 can be found by calculating the probability of X≥3 and dividing it by the probability of X>0. In this case, the probability mass function of X is given as P(X=x) = (x+1)/(x+2), where x=0,1,2,3,... Using this, we can determine the desired conditional probability.
To find the conditional probability of X≥3 given that X>0, we need to calculate the probability of X≥3 and divide it by the probability of X>0.
First, let's find the probability of X≥3. Since X follows a probability mass function given by P(X=x) = (x+1)/(x+2), we can compute the probability of X≥3 by summing the individual probabilities for x=3,4,5,...:
P(X≥3) = P(X=3) + P(X=4) + P(X=5) + ...
Substituting the probability mass function, we have:
P(X≥3) = (3+1)/(3+2) + (4+1)/(4+2) + (5+1)/(5+2) + ...
Simplifying this infinite series, we get:
P(X≥3) = (4/5) + (5/6) + (6/7) + ...
To find the conditional probability, we also need to calculate the probability of X>0. Using the probability mass function, we can determine this probability as:
P(X>0) = P(X=1) + P(X=2) + P(X=3) + ...
Substituting the values into the probability mass function, we have:
P(X>0) = (1+1)/(1+2) + (2+1)/(2+2) + (3+1)/(3+2) + ...
Simplifying this infinite series, we get:
P(X>0) = (2/3) + (3/4) + (4/5) + ...
Finally, the conditional probability of X≥3 given that X>0 is:
P(X≥3 | X>0) = P(X≥3) / P(X>0)
By dividing the expressions obtained for P(X≥3) and P(X>0), we can calculate the desired conditional probability.

This circle graph shows how the students in two sixth-grade classes get to school. Fifty students were surveyed. What percent takes the bus?
Answers
Forty percent of the students surveyed take the bus to school, as indicated by the circle graph.
To calculate the percent of students who take the bus to school, we can use the information provided in the circle graph. There are a total of 50 students surveyed, and the graph indicates that 20 of them take the bus. To find the percent, we can first divide the number who take the bus (20) by the total number surveyed (50). This gives us 0.4, which, when multiplied by 100, is 40%. Therefore, 40% of the students surveyed take the bus to school. Hence, Forty percent of the students surveyed take the bus to school, as indicated by the circle graph.

What are 3 different methods for solving systems of equations? When would you use each one?
The three methods are graphing, substitution and elimination. I just need help with when would you use each one!
Answers
Answer:
Graphing, Substitution, and Elimination.
Step-by-step explanation:
Graphing: Graphing is the best method to use when introducing a new student to solving systems of two equations in two variables because it gives them a visual to recognize what they are looking for. Graphing is less exact and often takes more time than the other methods. I only recommend graphing to find a solution if the problem comes with a graph already drawn and the intersection appears to be on an exact coordinate.
Substitution: Substitution gives the advantage of having an equation already written for the second variable when you find the first one. Substitution is best used when one (or both) of the equations is already solved for one of the variables. It also works well if one of the variables has a coefficient of 1.
Elimination: Elimination is the method that I use almost every time. If you are not sure which method to use, I recommend that you use elimination. Elimination is best used when both equations are in standard form (Ax + By = C). Elimination is also the best method to use if all of the variables have a coefficient other than 1.
I hope this gives you some idea about which method you should use. All three methods will give the same solution. Also, you should always check your answer in both equations to make sure it is correct.

if p > 5 is prime and p is divided by 10, show that the remainder is 1, 3, 7, or 9
Answers
If p > 5 is prime and p is divided by 10, then the remainders are 1, 3, 7, or 9
The given information, we know that p is a prime number greater than 5, and that p is divided by 10. This means that p must end in either 0 or 5. since those are the only digits that allow for a number to be divisible by 10.
However, we also know that p is prime, which means it cannot be divisible by any number other than 1 and itself. This rules out the possibility of p ending in 0. since any number ending in 0 is divisible by 10 (and therefore not prime).
Therefore, p must end in 5. This means that p can be written in the form:
p = 10n + 5
where n is some integer. Now, let's consider what happens when we divide p by 10:
p/10 = (10n + 5)/10 = n + 0.5
Since p/10 is not an integer (it has a decimal component of 0.5), we know that p cannot be evenly divided by 10. Therefore, when p is divided by 10, there must be a remainder.
To determine what possible remainders there could be, we can look at the possible values for the last digit of p. Since p ends in 5, the last digit can only be 1, 3, 7, or 9 (since these are the only digits that, when multiplied by 5 and added to 10n, result in a number ending in 5).
Therefore, if p > 5 is prime and p is divided by 10, the remainder must be either 1, 3, 7, or 9.

One week, Christopher earned $404.80 at his job when he worked for 22 hours. If he is paid the same hourly wage, how many hours would he have to work the next week to earn $368.00?
Answers
Christopher needs to work 20 hours during the next week to earn $368.00, assuming he is paid the same hourly wage as the previous week.
What is the proportion?
A proportion is a statement that two ratios are equal. Ratios compare two quantities by expressing the relationship between them in terms of their sizes or amounts. A proportion can be written in the form of a fraction or a ratio, and it expresses the equivalence of two ratios.
We can solve this problem using proportionality. We know that Christopher earned $404.80 for working 22 hours, which means his hourly wage can be calculated as:
hourly wage = total earnings / total hours worked = $404.80 / 22 hours = $18.40 per hour
Now we can use this hourly wage to find the number of hours Christopher needs to work to earn $368.00. Let's assume he needs to work x hours to earn $368.00. We can set up a proportion based on the hourly wage:
$18.40 per hour = $368.00 / x hours
To solve for x, we can cross-multiply:
$18.40 per hour * x hours = $368.00
Simplifying the left-hand side:
x = $368.00 / $18.40 per hour
x = 20 hours
Hence, Christopher needs to work 20 hours during the next week to earn $368.00, assuming he is paid the same hourly wage as the previous week.

Answers
a) No, a single spray of 10 grams of butter would not be enough to entirely cover the area of 4 slices of toast at 2 meters. The area of 4 slices of toast is larger than the area of 1 slice of toast, meaning that it would require more butter than 10 grams to cover the entire area.
b) A single spray of 10 grams of butter would be enough to cover the area of 8 slices of toast at 3 meters.
c) These changes would affect the amount of butter on each piece of toast in that there would be more butter on each piece with a larger rack and further distance from the "butter gun".
d) At 5 meters from the gun, our up-and-coming chef would be able to spray 16 slices of toast with a single burst of 10 grams of butter. Each piece of toast would also have more butter than it would if it was sprayed at a closer distance.
e) To duplicate the original single-slice toast at 5 meters from the gun, the chef would need to reduce the amount of butter being sprayed. He could do this by simply reducing the distance between the gun and the toast rack.

Answers
Answer: 15g+10a(less than or equal to <) 120

The system of inequalities that can be used to determine the amount of geometry problems (g) and algebra problems (a) is:
\(a + g \geq 10\)
\(10a + 15g \leq 120\)
We can translate the given situation into inequalities to get the system of inequalities that we can use to find the amount of algebra and geometry problems that can be completed.
Thus:a = amount of algebra problems
g = amount of geometry problems
Therefore, the inequality that at least 10 geometry and algebra problems will be:\(a + g \geq 10\)
Thus:
15 minutes for each geometric problem = 15g
10 minutes for each algebra problem = 10a
If all is intended to be taken within 120 minutes, therefore, the inequality that represents this will be:\(10a + 15g \leq 120\)

a square pyramid has a slant height of 3 in. and a surface area of 40 in.2. what is the length of an edge of the base, in inches?
Answers
Answer:
4 inches
Step-by-step explanation:
slant height = 3, surface area = 40.
let L = length of one side (since it's a square, it will be L for each edge of the base).
surface area = base + 4 sides of triangles
= L² X 4 (0.5 X base X height)
= L² X 4(0.5 X L X 3)
= L²+ 6L.
But surface area = 40.
So L² + 6L = 40.
Subtract 40 from both sides:
L² + 6L - 40 = 0.
Use the quadratic formula:
L = ((-b ± √(b² - 4ac)) ÷ 2a)
where a is the value of the first coefficient, b is value of the second and c is value of the constant.
L = ((-6 ± √(6² - 4(1)(-40))) ÷ 2(1))
= ((-6 ± √(36 + 160)) ÷ 2)
= (-6 ± 14) ÷ 2
= (-6 + 14) ÷ 2 or (-6 - 14) ÷ 2
= 4 or -10.
So L = 4 or -10. But L is a length, so it must be positive. So L = 4.
Length = 4 inches

Solve tan x=-1 for x over the interval (-infinity, infinity)
Answers
Step-by-step explanation:
We know that tangent is negative in the second and fourth quadrants of the unit circle, so we can use this fact to find the solutions of the equation tan x = -1.
First, we find the reference angle of x by taking the inverse tangent of 1 (since tangent is negative in the second quadrant, we take the negative of the reference angle):
tan^{-1}(1) = π/4
So the reference angle is π/4.
Next, we add π to the reference angle to find the solution in the second quadrant:
x = π - π/4 = 3π/4
Finally, we add 2π to the reference angle to find the solution in the fourth quadrant:
x = 2π + π/4 = 9π/4
Therefore, the solutions to the equation tan x = -1 over the interval (-∞, ∞) are:
x = 3π/4 + kπ, where k is an integer, or
x = 9π/4 + kπ, where k is an integer.

Richard Gaziano is a manager for Health Care, Inc. Health Care deducts Social Security, Medicare, and FIT (by percentage method) from his earnings. Assume a rate of 6.2% on $118,500 for Social Security and 1.45% for Medicare. Before this payroll, Richard is $1,000 below the maximum level for Social Security earnings. Richard is married, is paid weekly, and claims 2 exemptions. What is Richard’s net pay for the week if he earns $1,700?
Answers
Richard's net pay for the week, considering Social Security, Medicare, and FIT deductions, can be calculated by subtracting the total deductions from his gross earnings.
First, let's determine the amount deducted for Social Security. The Social Security rate is 6.2%, and the maximum earnings subject to this deduction are $118,500. Since Richard is $1,000 below the maximum level, the amount subject to Social Security deduction is $1,000. Therefore, the Social Security deduction is 6.2% of $1,000.
Next, we calculate the Medicare deduction. The Medicare rate is 1.45%, and it is applied to the entire earnings of $1,700.
To calculate the FIT deduction, we need additional information about Richard's taxable income, tax brackets, and exemptions. Without this information, we cannot provide an accurate calculation for the FIT deduction.
Finally, we subtract the total deductions (Social Security, Medicare, and FIT) from Richard's gross earnings of $1,700 to obtain his net pay for the week.
