Probability that a random sample of 45 oil changes result in a sample mean time less than 10 minutes is 0.0001

Given information:

The mean time is, = 16.2 min.

The standard deviation = 3.4 min.

Let X' is sample mean time :

Now the sample mean time is given by the equation

Z = (X' - μ) / (σ/√n)

Where, μ population mean time

(σ) is Standard deviation

(A) Probability of random sample of 45 oil changes:

p (X' < 10) = 1 - p (Z ≤ 12.33)

Z = (10 - 16.2) / (3.4 √45)

Answer:

It’s 2.07 pounds/in 3

Step-by-step explanation:

1 kilogram = 2.2 × pounds, so,2.07 × 1 kilogram = 2.07 × 2.2 pounds (rounded), or2.07 kilograms = 4.554 pounds.Step 2: Convert the decimal part in pounds to ouncesAn answer like "4.554 pounds" might not mean much to you because you may want to express the decimal part, which is in pounds, in ounces which is a smaller unit.So, take everything after the decimal point (0.55), then multiply that by 16 to turn it into ounces. This works because one pound equals 16 ounces. Thus,4.55 pounds = 4 + 0.55 pounds = 4 pounds + 0.55 × 16 ounces = 4 pounds + 8.8 ounces. So, 4.55 pounds = 4 pounds and 8 ounces (when rounded). Obviously, this is equivalent to 2.07 kilograms. Step 3: Convert from decimal ounces to a usable fraction of ounceThe previous step gave you the answer in decimal ounces (8.8), but how to express it as a fraction? See below a procedure, which can also be made using a calculator, to convert the decimal ounces to the nearest usable fraction: a) Subtract 8, the number of whole ounces, from 8.8:8.8 - 8 = 0.8. This is the fractional part of the value in ounces.b) Multiply 0.8 times 16 (it could be 2, 4, 8, 16, 32, 64, ... depending on the exactness you want) to get the number of 16th's ounces:0.8 × 16 = 12.8.c) Take the integer part int(12.8) = 13. This is the number of 16th's of a pound and also the numerator of the fraction.Finalmente, 2.07 quilogramas = 4 pounds 8 3/4 ounces.A fração 12/16 não está simplificada, e ainda pode ser reduzida para 3/4 para que possamos expressar como a fração mais simples possível.In short:2.07 kg = 4 pounds 8 3/4 ounces

In pigs, the length of pregnancies varies according to a Normal distribution with mean 114 days and standard deviation 5 days, approximately 2.28% of pig pregnancies are longer than 124 days.

We can start by standardizing the value 124 using the formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

So in this case:

z = (124 - 114) / 5 = 2

Using a standard normal distribution table or calculator, we can find that the proportion of values greater than 2 is approximately 0.0228.

Therefore, approximately 2.28% of pig pregnancies are longer than 124 days.

By using the substitution method, the value for (x,y) = (-2, 2)

The substitution method for solving a system of algebra equations is a process where by we make a variable (say variable x) the subject of the formula and substitute it into the second equation to solve for the other variable.

In essence, from the given system of equations; let's make x the subject of the formula in the first equation.

5x + 3y = -4

5x = -4 - 3y

Divide both sides by 5;

x = -4/5 - 3y/5

Now, we are going to substitute this value for x into the second equation. The second equation says:

y - 2x = 6

y - 2(-4/5 - (3y/5)) = 6

By solving for y;

y = 2

Now, let's replace the value of y with any of the given equation (2);

y - 2x = 6

2 - 2x = 6

-2x = 6 - 2

-2x = 4

Divide both sides by -2

-2x/-2 = 4/ -2

x = -2

Therefore, we can conclude that by using the substitution method, the value for (x,y) = (-2, 2)

Plug the numbers of the ordered pair into the equation: y = 6x

3 = 6 × ( 0 )

3 = 0

Three does not equal zero...

3 [tex]\neq[/tex] 0

The value of the integration are:

∫(√(2 + (cos x)²) / sec x - cosec x) dx = 3 ln|cos x - sin x| + √2 + C

∫arc tan√x dx = √x arc tan √x - ln|1 + x| + C

We have,

∫(√(2 + (cos x)²) / sec x - cosec x) dx:

We can simplify the expression in the integral as follows:

√(2 + (cos x)²)

= √(1 + (cos² x)) + √1

= √(sin² x + cos² x + cos² x) + 1

= √(2cos² x + 1) + 1

So the integral becomes:

∫[(√(2cos² x + 1) + 1) / (1/cos x - 1/sin x)] dx

= ∫[(√(2cos² x + 1) + 1) / ((sin x - cos x)/ (sin x cos x))] dx

= ∫[(√(2cos² x + 1) + 1) / ((sin x cos x - cos² x)/ (sin x cos x))] dx

= ∫[(√(2cos² x + 1) + 1) sin x / (cos x - sin x)] dx

Now we can make the substitution u = cos x - sin x, which gives us

du = (-sin x - cos x) dx, or -du = (sin x + cos x) dx.

Making this substitution and simplifying, we get:

∫[(√(2u² + 2) + 2) / u] du

= ∫[(√2(u² + 1) + √2) / u] du

= √2 ∫[(u² + 1)^(1/2) / u] du + 2 ∫(1/u) du

Using integration by substitution,

let w = u^2 + 1, then dw = 2u du, and we have:

= √2 ∫(1/w) dw + 2 ln|u|

= √2 ln|u| + 2 ln|u| + C

= 3 ln|cos x - sin x| + √2 + C

where C is the constant of integration.

And,

∫arc tan√x dx:

We can make the substitution u = √x, which gives us du = (1/2√x) dx, or 2u du = dx.

Substituting these into the integral, we get:

∫arc tan√x dx = ∫arc tan u x 2u du

Now, using integration by parts with u = arc tan u and dv = 2u du, we get:

∫arc tan u  2u du = u arc tan u - ∫(1 + u²)/(1 + u²)² du

= u arc tan u - ∫1/(1 + u²) du

= u arc tan u - ln|1 + u²| + C

Substituting back u = √x, we get:

∫arc tan√x dx = √x arc tan √x - ln|1 + x| + C

where C is the constant of integration.

Thus,

The value of the integration are:

∫(√(2 + (cos x)²) / sec x - cosec x) dx = 3 ln|cos x - sin x| + √2 + C

∫arc tan√x dx = √x arc tan √x - ln|1 + x| + C

To find the polynomial M, we need to rearrange the equation given to us. We can start by adding M to both sides of the equation to isolate the constant term. This gives us:

2[tex]x^{2}[/tex] - (1/3)ax + by = M

Now, we have the polynomial M in terms of x, a, b, and y. However, this is not in its simplest form yet. We can simplify this further by factoring out the coefficient of x. This gives us:

2([tex]x^{2}[/tex] - (1/6)ax) + by = M

Now, we can complete the square inside the brackets to get a perfect square trinomial. This means taking half of the coefficient of x, squaring it, and adding it and subtracting it inside the brackets. This gives us:

2((x - [tex](\frac{1}{12}a)^{2}[/tex]  - (1/144)[tex]a^{2}[/tex]) + by = M

Simplifying this further, we get:

2(x - [tex](\frac{1}{12}a)^{2}[/tex]  - (1/72[tex]a^{2}[/tex] + by = M
