A sample of 10 washing machines is selected from a process that is 8% nonconforming. What is the probability of 1 nonconforming washing machine in the sample
To solve this problem, we can use the binomial probability formula:
P(X=k) = (n choose k) * p^k * (1-p)^(n-k)
Where:
- P(X=k) is the probability of getting k nonconforming washing machines in the sample
- n is the sample size, which is 10 in this case
- p is the probability of getting a nonconforming washing machine, which is 0.08
- (n choose k) is the binomial coefficient, which is the number of ways to choose k items from n without replacement, and is calculated as n! / (k! * (n-k)!)
So, to find the probability of getting 1 nonconforming washing machine in the sample, we plug in k=1:
P(X=1) = (10 choose 1) * 0.08^1 * (1-0.08)^(10-1)
P(X=1) = 10 * 0.08 * 0.9227
P(X=1) = 0.0738
Therefore, the probability of getting 1 nonconforming washing machine in the sample is approximately 0.0738, or 7.38%.

the probability of at least one head in two flips of a coin is
The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.
To find the probability of at least one head in two flips of a coin, we can use the complement rule. The complement of the event "at least one head" is "no heads."
The probability of getting no heads in two flips of a coin is (1/2) x (1/2) = 1/4.
Therefore, the probability of getting at least one head in two flips of a coin is:
1 - (probability of no heads) = 1 - 1/4 = 3/4
The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.
In other words, if you flip a coin twice, the probability of getting at least one head is relatively high, and you are more likely to get at least one head than to get no heads at all.

Kari and Darius have two cylindrical cups to drink
juice from
Kari's cup is 8 inches tall and has a diameter of 3
inches.
Darius's cup has a diameter of 4 inches and is 5
inches tall.
Each believe their cup can hold more juice.
Which cup holds more juice?
How much more juice can the larger cup hold?
Answer: Kari's cup can hold more juice
She holds 6.28 inches^3 more than Darius's cup.
Step-by-step explanation:
1: Find the volume that both cylinders hold:
Kari:
V=πr2h=π·1.52·8≈56.54867
Volume is about 56.55 inches^3
Darius:
V=πr2h=π·22·4≈50.26548
Volume is about 50.27 inches^3
2: Subtract both values:
56.55-50.27=6.28
3: Make your statement:
Kari's cup can hold more juice
She holds 6.28 inches^3 more than Darius's cup.
Let A={46,51,55,70,80,87,98,108,122} and R be an equivalence relation defined on A where aRb if and only if a≡b mod 4. Show the partition of A defined by the equivalence classes of R.
The partition of A defined by the equivalence classes of R is {[51, 55, 87, 91, 122], [46, 70, 98, 108], [80, 84, 116], [87, 91]}.
The equivalence relation R defined on the set A={46, 51, 55, 70, 80, 87, 98, 108, 122} is given by aRb if and only if a ≡ b (mod 4), where ≡ denotes congruence modulo 4.
To determine the partition of A defined by the equivalence classes of R, we need to identify sets that contain elements related to each other under the equivalence relation.
After examining the elements of A and their congruence modulo 4, we can form the following partition:
Equivalence class 1: [51, 55, 87, 91, 122]
Equivalence class 2: [46, 70, 98, 108]
Equivalence class 3: [80, 84, 116]
Equivalence class 4: [87, 91]
These equivalence classes represent subsets of A where elements within each subset are congruent to each other modulo 4. Each element in A belongs to one and only one equivalence class.
Thus, the partition of A defined by the equivalence classes of R is {[51, 55, 87, 91, 122], [46, 70, 98, 108], [80, 84, 116], [87, 91]}.

2/3x-1/5x=x-1 what is x
The value of x that satisfies the equation is x = 15/8, which is equivalent to 1.875.
To solve the equation (2/3)x - (1/5)x = x - 1 and find the value of x, we can follow these steps:
Combine like terms on the left side of the equation:
(2/3 - 1/5)x = x - 1
Find a common denominator for the fractions on the left side. The common denominator for 3 and 5 is 15, so we rewrite the equation as:
(10/15 - 3/15)x = x - 1
Simplify the left side of the equation:
(7/15)x = x - 1
To eliminate the fraction, we can multiply both sides of the equation by the denominator of the fraction, which is 15:
15 * (7/15)x = 15 * (x - 1)
This simplifies to:
7x = 15x - 15
Subtract 15x from both sides of the equation to isolate the x term:
7x - 15x = -15
Simplifying further:
-8x = -15
Divide both sides of the equation by -8 to solve for x:
x = (-15) / (-8)
Simplifying the division:
x = 15/8

Write the equation of a line with the slope -3 and y-intercept of 5
O y = 5x + 3
O y = -5x + 3
O y = 5x - 3
O y = -3x + 5
Answer:
\(\fbox{y = -3x + 5}\)
Step-by-step explanation:
You are given the slope and the y-intercept of the line; so you can substitute these values into slope-intercept form: \(y=mx+b\);
where \(m= \ $slope = -3\)and \(y-$int = 5\)Plugging these values into slope-intercept form gives:
\(y=(-3)x+(5)\)\(y=-3x+5\)Another way to find the slope-intercept form of a line given the slope and a point:We are given the slope and a point that the line passes through, so we can use the point-slope equation to find the slope-intercept form of the line.
The point that the line passes through is the y-intercept: \((0,5)\).
Point-slope form:
\(y-y_1=m(x-x_1)\)where \((x_1, \ y_1)\) are the coordinates of the point that the line passes through and \(m= $ slope of the line.\)
Substitute \(m=-3\) and \((0,5)\) into the point-slope form equation.
\(y-(5)=-3(x-(0))\)Simplify the equation on both sides.
\(y-5=-3(x)\)Add 5 to both sides of the equation.
\(y=-3x+5\)This is in slope-intercept form: \(y=mx+b\), so we are done.
The answer is \(D) \ $y = -3x+5\).
find the average rate of hange for the function f(x)=2 cos(x^2) on the interval [1,3]
The average rate of change for the function f(x) = 2 cos(x^2) on the interval [1, 3] is approximately -0.198.
The formula for an average rate of change is (f(b) - f(a))/(b - a), where a and b are the endpoints of the interval. Plugging in the values, we get (f(3) - f(1))/(3 - 1) = (2cos(9) - 2cos(1))/(2) = -0.198. Therefore, the average rate of change for the function f(x) on the interval [1,3] is approximately -0.198.

Given function is
\(\rm \longmapsto\:f = \bigg(x, \: \dfrac{ {x}^{2} }{ {x}^{2} + 1} \bigg) : x \: \in \: R\)
To find the range of the function f, Let assume that
\(\rm \longmapsto\:y = \dfrac{ {x}^{2} }{ {x}^{2} + 1} \)
\(\rm \longmapsto\: {yx}^{2} + y = {x}^{2} \)
\(\rm \longmapsto\: {yx}^{2} - {x}^{2} = - y\)
\(\rm \longmapsto\: - {x}^{2} (1 - y) = - y\)
\(\rm \longmapsto\: {x}^{2} (1 - y) = y\)
\(\rm \longmapsto\: {x}^{2} = \dfrac{y}{1 - y} \)

The equation of the line passing through the point (4,2) and perpendicular to the line passing through points (9,7) and (11,4) is:
y - 2 = (2/3)(x - 4)
To find the equation of a line passing through the point (4,2) and perpendicular to the line passing through the points (9,7) and (11,4), we can follow these steps:
Step 1: Find the slope of the line passing through (9,7) and (11,4).
Slope = \(\frac{y_{2} - y_{1} }{x_{2} - x_{1} }\)
Slope = (4 - 7) / (11 - 9)
Slope = -3 / 2
Step 2: The line perpendicular to this line will have a negative reciprocal slope.
Perpendicular Slope = -1 / Slope
Perpendicular Slope = -1 / (-3/2)
Perpendicular Slope = 2/3
Step 3: Use the point-slope form of the equation to find the equation of the line.
y - y1 = m(x - x1), where (x1, y1) is the given point (4,2) and m is the perpendicular slope.
y - 2 = (2/3)(x - 4)
Therefore, the equation of the line passing through the point (4,2) and perpendicular to the line passing through the points (9,7) and (11,4) is:

To expand (x + 4)², we can use the formula for squaring a binomial: (a + b)² = a² + 2ab + b². In this case, a = x and b = 4.
So,
(x + 4)² = x² + 2(x)(4) + 4²

find two numbers whose difference is 164 and whose product is a minimum.
Answer: The lowest possible product would be -6724 given the numbers 82 and -82.
We can find this by setting the first number as x + 164. The other number would have to be simply x since it has to have a 164 difference.
Next we'll multiply the numbers together.
x(x+164)
x^2 + 164x
Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2
-b/2a = -164/2(1) = -164/2 = -82
So we know one of the values is -82. We can plug that into the equation to find the second.
x + 164
-82 + 164
