The weight of the eggs produced by a certain breed of hen are normally distributed with a mean of 65 grams and standard deviation of 5 grams. What is the probability that a sample of 12 eggs will have a mean weight of more than 68 grams?
There is a 0.0838 or 8.38% chance that a sampling of 12 eggs has a weighted mean greater than 68 grammes.
The Central Limit Theorem, which asserts that group means of a large sample size from every population, irrespective of its distribution, will be roughly distributed normally with an average equal to the inhabitants imply and a variance equal to the standard deviation of the population multiplied by the square root of the random sample, must be used to solve this problem.
As a result, there is a 0.0838 or 8.38% chance that a sampling of 12 eggs has a weighted mean greater than 68 grammes. When n is the sample size, x is the sample mean, is the population mean, and seems to be the population standard deviation.
In this instance, n = 12 eggs, x = 68 grammes, = 65 grammes, = 5 grammes. When these values are added to the formula, you obtain:[tex]z = (68 - 65) / (5 / √12) = 1.385[/tex]

Distance:
Distance is a numerical or sometimes qualitative measurement of the distance between objects or points. In physics or common usage, distance can refer to a physical length or an estimate based on other criteria. Since spatial cognition is a rich source of conceptual metaphors in human thought, the term is also often used metaphorically to refer to a measure of the amount of difference between two similar objects or some degree of separation.
Most of these concepts of distance, whether physical or metaphorical, are formalized in mathematics using the concept of metric spaces.
According to the Question:
total distance (one way): 1,023 miles
average driving speed: 60 miles per hour
driving time on first day: 10 hours.

NOTE: Answers using z-scores rounded to 3 (or more) decimal places will work for this problem. The population of weights for men attending a local health club is normally distributed with a mean of 174 lbs and a standard deviation of 29-lbs. An elevator in the health club is limited to 35 occupants, but it will be overloaded if the total weight is in excess of 6475 -lbs. Assume that there are 35 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded?
the average weight beyond which the elevator would be considered overloaded is approximately 7616.56 lbs.
What is probability?
Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probabilities are usually expressed as fractions, decimals, or percentages.
The total weight of 35 men in the elevator can be modeled by the sum of 35 independent and identically distributed normal random variables with mean 174 lbs and standard deviation 29 lbs. Let X be the weight of one man, then the total weight of 35 men is W = 35X.
The mean of W is:
μW = E(W) = E(35X) = 35 E(X) = 35 * 174 = 6090 lbs
The variance of W is:
Var(W) = Var(35X) = 35^2 Var(X) = 35^2 * 29^2 = 899150
The standard deviation of W is:
σW = sqrt(Var(W)) = sqrt(899150) = 947.85
To find the average weight beyond which the elevator would be considered overloaded, we need to find the weight that corresponds to the 95th percentile of the distribution of W, since the elevator is overloaded if the total weight is in excess of 6475 lbs.
Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to the 95th percentile: z = 1.645 (rounded to 3 decimal places).
We can then find the weight w that corresponds to this z-score:
w = μW + z * σW
w = 6090 + 1.645 * 947.85
w ≈ 7616.56
Therefore, the average weight beyond which the elevator would be considered overloaded is approximately 7616.56 lbs.

ECOLOGY: DDT is an insecticide that has been used by farmers. It decays slowly and it is sometimes absorbed by plants that animals and humans eat. DDT absorbed in the mud at the bottom of a lake is degraded into harmless products by bacterial action. Experimental data shows that 10% of the initial amount is eliminated in 5 years(so what would remain?)
a) Find the value of k in the decay formula: y = ae-kt (Pert with different letters)
b) How much of the original amount of DDT is left after 10 years?
c) The U.S. Environmental Protection Agency banned almost all use of DDT in the U.S. in 1972. If none has been used near the lake since then, in what year will the concentration of DDT fall below 25%?
Therefοre , the sοlutiοn οf the given prοblem οf percentage cοmes οut tο be a)k ≈ 0.0279,b)y = 0.593a and c)t ≈ 78.5 .
Describe percentages.In statistics, a percentage is a figure οr an integer that is expressed as a fractiοn οf 100. Additiοnally, the wοrds "pct.," "pct," but alsο "pc" are rarely used. The "%" symbοl, hοwever, is cοmmοnly used tο denοte it. There are nο dimensiοns; the percentage tοtal is flat.
Percentages are really just numbers because the numeratοr is 100. Tο indicate that a number is a percentage, either the percent character (%) οr the text "percent" must appear befοre it.
Here,
a) We can apply the exponential decline equation:
=> [tex]y = ae^{(-kt)} (-kt)[/tex]
[tex]0.9a = ae^{(-5k)} (-5k)[/tex]
Using a to divide both sides:
[tex]0.9 = e^{(-5k)} (-5k)[/tex]
Using both sides' natural logarithms:
ln(0.9) = -5k
calculating k:
[tex]k = -ln(0.9)/5[/tex]
k ≈ 0.0279
Consequently, the decline formula's value of k is roughly 0.0279.
b)
[tex]y = ae^{(-kt)} (-kt)[/tex]
[tex]y = an e^{(-0.0279*10)[/tex]
[tex]y = 0.593a[/tex]
As a result, after 10 years, only about 59.3% of the initial DDT is still present.
c)
[tex]0.25a = ae^{(-0.0279t) (-0.0279t)[/tex]
Using a to divide both sides:
[tex]0.25 = e^{(-0.0279t) (-0.0279t)[/tex]
Using both sides' natural logarithms:
ln(0.25) = -0.0279t
calculating t:
t = -ln(0.25)/0.0279
t ≈ 78.5
Therefore, roughly 78.5 years after the ban in 1972, or in the year 2050, the concentration of DDT will drop below 25%.

A manufacturer buys a new machine that costs $50,000. The estimated useful life for the machine is ten years. The
achine can produce 1,000 units per month. If the machine ran at its capacity for ten years, what would be the fixed cost per unit based on
e cost of the machine per part manufactured? (Round to the nearest penny)
oooo
a) $. 42 / unit
b) $1. 00/unit
c) $4,167 / unit
d) $5,000/unit
The fixed cost per unit based on cost of the machine per part manufactured is $0.42 per unit.
What is multiplication ?
Multiplication is a mathematical operation that involves finding the product of two or more numbers or quantities. It is a way of adding a number to itself multiple times. The symbol used to represent multiplication is an "x" or a dot "·". For example, in the expression 5 x 6 = 30, 5 and 6 are multiplied together to give the product of 30. Multiplication can also be represented using parentheses, such as (5)(6) = 30. In addition, multiplication can be done with decimals, fractions, variables, and matrices.
To find the fixed cost per unit based on the cost of the machine per part manufactured, we need to calculate the total number of units produced by the machine over its estimated useful life, and then divide the cost of the machine by that number.
The machine runs at its capacity of 1,000 units per month for 10 years, so the total number of units produced by the machine is:
10 years x 12 months/year x 1,000 units/month = 120,000 units
The cost of the machine is $50,000, so the fixed cost per unit based on the cost of the machine per part manufactured is:
$50,000 ÷ 120,000 units = $0.4167 per unit
Rounding this to the nearest penny gives us the final answer of:
$0.42 per unit (option a)
Therefore, the fixed cost per unit based on cost of the machine per part manufactured is $0.42 per unit.

To get distance we use formula derived in Question 15, which gives an approximation of the circumference of the wheel based on its diameter which is 471.24nft
[tex]C = \pi d[/tex]
where d: diameter and C: circumference.
With the diameter of 150 feet provided, we can calculate the wheel's circumference as follows:
[tex]C = π(150) = 471.24 ft[/tex]
For our issue, let's define some variables:
n: the number of times the Ferris wheel has rotated
d: the Ferris wheel's circumference
C: the Ferris wheel's circumference
S: the total distance a passenger travels
Given that a passenger travels one circumference every spin, the overall distance after n rotations is roughly equal to:
S ≈ nC
In place of our values, we obtain:
[tex]S = n(471.24) = 471.24n ft[/tex]
So, assuming the Ferris wheel has a 150-foot diameter, we may use the equation S 471.24n to roughly calculate the total distance a passenger would have travelled in ferris wheel spins. However keep in mind that this is just a rough estimate, and it might not be completely correct depending on things like the size of the carriage and the height of the passenger above the ground.

The expression (6x+5)/(x+7) written in the form quotient +( remainder )/( divisor ) is
6x + 5 + ( -2 )/( x + 7 ), The expression can be written as the quotient of 6x + 5 divided by x + 7, plus the remainder of -2, all divided by the divisor of x + 7.
To calculate (6x+5)/(x+7), first we must add x to both the numerator and the denominator to get (6x+x+5)/(x+7+x), which simplifies to (7x+5)/(2x+7). Then, divide the numerator by the denominator to get (7x+5)/(2x+7) = 3.5x + 2.5. To find the remainder, subtract 3.5x and 2.5 from both the numerator and denominator, which gives us (7x+5)-(3.5x+2.5) = 3.5x + 2.5 - (3.5x + 2.5) = 3.5x - 2.5. Lastly, divide the remainder by the divisor (2x+7) to get (3.5x-2.5)/(2x+7). Therefore, the answer is 3.5x + 2.5 + (3.5x - 2.5)/(2x+7).

To determine the zeros of f(x) and state the multiplicity of each zero, the following steps should be followed:
Step 1: Determine the roots of the polynomial
To solve for the roots of f(x), use the quadratic formula. f(x) = x⁴ + 12x² - 64
a = 1, b = 12, c = -64
Using the quadratic formula, we have:
x = (-b ± √(b² - 4ac)) / 2a
x = (-12 ± √(12² - 4(1)(-64))) / 2(1)
x = (-12 ± √400) / 2
x = (-12 ± 20) / 2
x₁ = -16
x₂ = 4
x₃ = x₄ = 0
Step 2: State the multiplicity of each zero
After determining the roots of f(x), determine the multiplicity of each root by using the concept of multiplicity. A root has a multiplicity of p if and only if f(x) has a factor of (x - r)ᵖ.
From the quadratic equation above, we have:
x₁ = -16 (multiplicity 1)
x₂ = 4 (multiplicity 1)
x₃ = x₄ = 0 (multiplicity 2)
Therefore, the zeros of f(x) and their multiplicities are: x = -16 (multiplicity 1), x = 4 (multiplicity 1), and x = 0 (multiplicity 2).
The final answer is as follows:
x = -16 with multiplicity 1

What do you mean by probability?Probability is the concept that describes the likelihood of an event occurring. In real life, we frequently have to make predictions about how things will turn out. About an event's outcome, we might be certain or uncertain.
When this occurs, we state that there is a possibility that the event will occur. In general, probability has many excellent applications in games, commerce, and this newly growing area of artificial intelligence.
Now from the question,
The probability that the biscuit is made by machine and not broken:
1 - 25% × 2%
= 50%
Now not broken probability = 1- 25% × 2%
Now next, the probability of breakage: 2% + 3% + 5% = 10%
Finally, the probability that biscuit is not made by machine = 1-5% = 95%

A particle moves according to a law of motion s = f(t), t ≥ 0, where t is measured in seconds and s in feet. (if an answer does not exist, enter dne. ) f(t) = t3 − 8t2 + 25t
f(t) = t3 − 8t2 + 25t + 10. When all the parts are put together, the equation represents a combination of the 3 components, representing a law of motion for a particle.
This equation represents a law of motion, where t is measured in seconds and s in feet. This equation can be broken down into 3 parts; t3, -8t2 and 25t + 10. The t3 part of the equation represents a cubic function, which is usually associated with acceleration. The -8t2 part is a quadratic function, which is typically associated with velocity. Finally, the 25t + 10 is a linear function, which is usually associated with displacement. When all the parts are put together, the equation represents a combination of the 3 components, representing a law of motion for a particle.

finnd the equation of straight line passing through the point (3a,0) and (0,3b) also shwo that the line passese throught the poinits (a , 2b)
Answer:
see explanation
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3a, 0 ) and (x₂, y₂ ) = (0, 3b )
m = [tex]\frac{3b-0}{0-3a}[/tex] = [tex]\frac{3b}{-3a}[/tex] = - [tex]\frac{b}{a}[/tex]
the line crosses the y- axis at (0, 3b ) ⇒ c = 3b
y = - [tex]\frac{b}{a}[/tex] x + 3b ← equation of line
to show that (a, 2b ) lies on the line , substitute x = a into the equation and if y = 2b then the point lies on the line
y = - [tex]\frac{b}{a}[/tex] (a) + 3b = - b + 3b = 2b
then the line passes through the point (a, 2b )
