Mrs. Harrison bought a new clothes dryer for $618 the stae sale tax was 7 1/2% what was the total cost
Answers
The total cost of the clothes dryer, including the sales tax, is $664.35.
To calculate the total cost, we need to add the purchase price of the clothes dryer to the amount of sales tax applied.
The sales tax is calculated as a percentage of the purchase price. In this case, the sales tax rate is 7.5%.
First, let's calculate the sales tax amount:
Sales Tax = 7.5% of $618
Sales Tax = (7.5/100) * $618
Sales Tax = 0.075 * $618
Sales Tax = $46.35
Next, we add the sales tax to the purchase price to find the total cost:
Total Cost = Purchase Price + Sales Tax
Total Cost = $618 + $46.35
Total Cost = $664.35

suppose that a randomly generated list of number from 0 to 9 is being used to simulate an event that has a proabbility of success of 70%. which of these groups of numbers could represent a success? (a 0, 1, 2, 3, 4, 5 6, 7.) (b 0, 1 , 2, 3, 4, 5, 6, 7, 8) (c 0, 1, 3. 4, 5) (d 0, 1, 2, 3, 4, 5, 6)
Answers
To simulate an event with a probability of success of 70%, we need to choose a group of numbers that represents 70% of the total possible outcomes (0 to 9). Since there are 10 possible outcomes (0-9), we need a group that contains 70% of these outcomes, which means 7 numbers.
Let's examine each group:
(a) 0, 1, 2, 3, 4, 5, 6, 7 - This group contains 8 numbers, representing 80% of the total outcomes. Therefore, it cannot be used to simulate a 70% probability of success.
(b) 0, 1, 2, 3, 4, 5, 6, 7, 8 - This group contains 9 numbers, representing 90% of the total outcomes. Therefore, it cannot be used to simulate a 70% probability of success.
(c) 0, 1, 3, 4, 5 - This group contains 5 numbers, representing 50% of the total outcomes. Therefore, it cannot be used to simulate a 70% probability of success.
(d) 0, 1, 2, 3, 4, 5, 6 - This group contains 7 numbers, representing 70% of the total outcomes. This group can be used to simulate a 70% probability of success.
The correct answer is (d) 0, 1, 2, 3, 4, 5, 6, as it represents 70% of the total outcomes in the randomly generated list of numbers from 0 to 9.

Find the indefinite integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.)
∫x3−5x2+2/x−5dx
Answers
To find the indefinite integral of the given function, we need to use the method of partial fractions. First, we factor the denominator:
x-5 = 0
x = 5
Therefore, x-5 is a linear factor, and we can write:
(x^3 - 5x^2 + 2) / (x-5) = Ax^2 + Bx + C + D/(x-5)
where A, B, C, and D are constants that we need to find. To do this, we can multiply both sides by (x-5) and then substitute x=5 to get:
A(5)^2 + B(5) + C + D/(5-5) = 5^3 - 5(5)^2 + 2
This simplifies to:
25A + 5B + C = 108
Next, we can differentiate both sides of the partial fraction equation to get:
x^3 - 5x^2 + 2 = (Ax^2 + Bx + C)(x-5) + D
Expanding and equating coefficients, we get:
A = 1, B = -10, C = 23, D = -113
Therefore, we can write:
∫x^3−5x^2+2/(x−5) dx = ∫(x^2 - 10x + 23) dx - ∫(113/(x-5)) dx
The first integral can be evaluated using the power rule:
∫(x^2 - 10x + 23) dx = (1/3)x^3 - 5x^2 + 23x + C1
where C1 is the constant of integration.
For the second integral, we need to use the logarithmic rule:
∫(113/(x-5)) dx = 113 ln|x-5| + C2
where C2 is the constant of integration. Note that we need to include the absolute value of x-5 to account for the fact that the denominator can be negative for some values of x.
Therefore, the final answer is:
∫x^3−5x^2+2/(x−5) dx = (1/3)x^3 - 5x^2 + 23x + 113 ln|x-5| + C
where C is the constant of integration.

Answers
Answer: Option B, i.e., \(h=\dfrac{V}{\pi r^2}\)
Option C, i.e., \(h=4\text{ cm}\).
Step-by-step explanation:
It is given that formula for the volume V of a cylinder is
\(V=\pi r^2h\)
We need to find the formula for h.
Divide both sides by \(\pi r^2\).
\(\dfrac{V}{\pi r^2}=h\)
\(h=\dfrac{V}{\pi r^2}\)
Therefore, the required formula for height is \(h=\dfrac{V}{\pi r^2}\). Hence option B is correct.
If volume is 36π cm³ and base with a radius of 3 cm, then height of the cylinder is
\(h=\dfrac{36\pi}{\pi (3)^2}\)
\(h=\dfrac{36}{9}\)
\(h=4\text{ cm}\)
Therefore, the height of a cylinder is 4 cm. Hence option C is correct.

So, we have:
\(\mathbf{y = cot(x + 2)}\)
Next, stretch the function horizontally by a factor of 1/5
The rule of this transformation is:
\(\mathbf{(x,y) \to (\frac 15x,y)}\)
So, we have:
\(\mathbf{y=cot[\frac 15(x+2)]}\)
Lastly, stretch the function vertically by a factor of 3
The rule of this transformation is:
\(\mathbf{(x,y) \to (x,3y)}\)

A book has n typographical errors. Two proofreaders, A and B independently read the book and check for errors. A catches each error with probability p1 independently. Likewise for B, who has probability p2 of catching any given error. Let X1 be the number of typos caught by A,X2 be the number caught by B, and X be the number caught by at least one of the two proofreaders. (a) Find the distribution of X. (b) Find E(X). (c) Assuming that p1=p2=p, find the conditional distribution of X1 given that X1+X2=m.
Answers
The denominator can be calculated as the sum of the probabilities of all possible cases where X1 + X2 = m:
P(X1 + X2 = m) = Σ(P(X1 = k, X2 = m - k)), for k = 0 to m
We obtain the conditional distribution P(X1 = k | X1 + X2 = m) for k = 0 to m.
(a) To find the distribution of X, we can consider the cases where A catches k errors and B catches (X - k) errors, for k = 0 to X. The probability of A catching k errors is given by the binomial distribution:
P(X1 = k) = C(X, k) * p1^k * (1 - p1)^(X - k)
Similarly, the probability of B catching (X - k) errors is:
P(X2 = X - k) = C(X, X - k) * p2^(X - k) * (1 - p2)^(X - (X - k))
Since X is the number caught by at least one of the two proofreaders, the distribution of X is given by the sum of the
probabilities for each k:
P(X = x) = P(X1 = x) + P(X2 = x), for x = 0 to X
(b) To find E(X), we can sum the product of each possible value of X and its corresponding probability:
E(X) = Σ(x * P(X = x)), for x = 0 to X
(c) Assuming p1 = p2 = p, we can find the conditional distribution of X1 given that X1 + X2 = m using the concept of conditional probability. Let's denote X1 + X2 = m as event M.
P(X1 = k | M) = P(X1 = k and X1 + X2 = m) / P(X1 + X2 = m)
To find the numerator, we need to consider the cases where X1 = k and X1 + X2 = m:
P(X1 = k and X1 + X2 = m) = P(X1 = k, X2 = m - k)
Using the same logic as in part (a), we can calculate the probabilities P(X1 = k) and P(X2 = m - k) with p1 = p2 = p.
Finally, the denominator can be calculated as the sum of the probabilities of all possible cases where X1 + X2 = m:
P(X1 + X2 = m) = Σ(P(X1 = k, X2 = m - k)), for k = 0 to m
Thus, we obtain the conditional distribution P(X1 = k | X1 + X2 = m) for k = 0 to m.

Answer:
y = -1/2x + 9
Step-by-step explanation:
(0, 9) and (8, 5)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(5 - 9) / (8 - 0)
Simplify the parentheses.
= (-4) / (8)
Simplify the fraction.
-4/8
= -1/2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (8, 5). Plug in the x and y values into the x and y of the standard equation.
5 = -1/2(8) + b
To find b, multiply the slope and the input of x(8)
5 = -4 + b
Now, add 4 to both sides to isolate b.
9 = b
Plug this into your standard equation.
y = -1/2x + 9
This is your equation.
Check this by plugging in the other point you have not checked yet (0, 9).
y = -1/2x + 9
9 = -1/2(0) + 9
9 = 0 + 9
9 = 9
Your equation is correct.

Consider a weekly raffle having 100 tickets, one of which win a price each week. If you want to maximize your chance of winning something, is it better to buy 10 tickets in on raffle or one ticket in 10 different raffles? Or is it the same?
Answers
The probability of winning with 10 tickets in one raffle is 100 times greater than the probability of winning with one ticket in 10 different raffles. This means that buying 10 tickets in one raffle is the best way to maximize your chances of winning something.
Buying ten tickets in one raffle will give you a greater chance of winning the prize than buying one ticket in ten different raffles. In the first scenario, you have a 10% chance of winning the prize (10 tickets out of 100 total tickets). In the second scenario, your chances are only 1% (1 ticket out of 100 tickets in each raffle).
Mathematically, this can be expressed as the probability of winning with 10 tickets in one raffle (P1): P1 = 10/100 = 0.1
The probability of winning with one ticket in 10 different raffles (P2): P2 = (1/100)^10 = (0.01)^10 = 1/10,000 = 0.0001
Therefore, the probability of winning with 10 tickets in one raffle is 100 times greater than the probability of winning with one ticket in 10 different raffles. This means that buying 10 tickets in one raffle is the best way to maximize your chances of winning something.

If she has two more $5 bills than $10 bills, and three more $1 bills than $5 bills, how many of each bill does Jemila have?
Answers
Answer:
She has 3 $10 bills, 5 $5 bills and 8 $1
3 times 10= $30
5 times 5 = $25
8 times 1 = $8
$30 + $25 + $8 = $63
A system of equations is a group of equations that can be solved simultaneously. Here we can find one that allows us to solve the given question.
We will see that: Jemila has 8 $1 bills, 5 $5 bills, and 3 $10 bills.
First, let's define the variables:
x = number of $1 bills in the piggy bank.y = number of $5 bills in the piggy bank.z = number of $10 bills in the piggy bank.Then the total amount of money in the piggy bank is:
$1*x + $5*y + $10*z
And we know that the total value is $63, then one equation is:
$1*x + $5*y + $10*z = $63
We also know that she has two more $5 bills than $10 bills, then:
y = z + 2
We also know that she has three more $1 bills than $5 bills, then:
x = y + 3
So our system of equations is:
$1*x + $5*y + $10*z = $63
y = z + 2
x = y + 3
To solve this, we need to isolate one of the variables in one of the equations. We can see that some variables are already isolated, like on the second or third equations.
For example, we can replace the second equation into the first and third ones:
$1*x + $5*y + $10*z = $63
x = y + 3
$1*x + $5*(z + 2) + $10*z = $63
x = (z + 2) + 3
Now we can simplify these to get:
$1*x + $15*z + $10 = $63
x = z + 5
Now we can replace the second equation on the first one:
$1*x + $15*z + $10 = $63
$1*(z + 5) + $15*z + $10 = $63
Finally, we can solve this for z.
$16*z + $5 + $10 = $63
$16*z = $63 - $15
$16*z = $48
z = $48/$16 = 3
z = 3
Now that we know the value of z, we can use it in the equations:
x = z + 5 = 3 + 5 = 8
y = z + 2 = 3 + 2 =5
Then the solution is:
x = 8y = 5z = 3Then Jemila has 8 $1 bills, 5 $5 bills, and 3 $10 bills.
