There are no extreme values of the function ƒ(x, y, z) = xy z^2 on the given intersection.

To find the extreme values of the function ƒ(x, y, z) = xy z^2 on the given intersection, we need to find the critical points.

First, let's substitute y = x into the equation of the sphere:

x^2 (x^2) z^2 = 4

Simplifying the equation, we have:

x^4 z^2 = 4

Taking the square root of both sides, we get:

x^2 z = ±2

Now, we can substitute y = x into the equation of the function:

ƒ(x, y, z) = x(x)(z^2) = x^2 z^2

Since we have x^2 z^2 in both the function and the equation of the sphere, we can substitute x^2 z^2 = 4:

ƒ(x, y, z) = 4

The function ƒ(x, y, z) = 4 is a constant function, which means it has no critical points.

The sampling distribution of sample means is a mean of 79 and a standard deviation of 3.

The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.

Given that,

Population mean,  \(\bar{x}\) = 79

Population standard deviation, σ = 18

Sample size, n = 36

We have to determine the mean and standard deviation of a sampling distribution of sample means.

Let X denotes a random variable distributed with a mean and standard deviation of 85 and 28 respectively.

Also, if a random sample of size n is drawn from the population, then the sample mean is denoted by \(\bar{x}\).

The sampling distribution of sample means \(\bar{x}\) is given by:

ц \(\bar{x}\) = ц

σ \(\bar{x}\)  = σ/√n

Therefore, for the sample size n = 36, the sampling distribution of sample means \(\bar{x}\) is obtained as:

ц \(\bar{x}\) = 79

σ \(\bar{x}\)  = 18/√36 = 3

Hence, the required sampling distribution of sample means is mean of 79 and a standard deviation of 3.

The surface area can be obtained by integrating the square root of the sum of the squares of the partial derivatives of f(x, y) with respect to x and y over the region r.

To find the surface area, we need to calculate the square root of the sum of the squares of the partial derivatives of f(x, y) with respect to x and y. In this case,

√(1 + (∂f/∂x)^2 + (∂f/∂y)^2) becomes √(1 + 16x^2 + 4y^2).

Then, we integrate this expression over the region r, which is the disk of radius 3 centered at the origin.

Using polar coordinates, we can rewrite the integral as

∫∫r √(1 + 16r^2 cos^2 θ + 4r^2 sin^2 θ) r dr dθ, where 0 ≤ r ≤ 3 and 0 ≤ θ ≤ 2π. By evaluating this integral, we can determine the area of the given surface.

The required positive five-digit integer of the form ab,cba; which should be divisible by 11 is 87,978

Explain the divisibility test of 11.

For a number to be divisible by 11, the difference between the sum of its odd digits (1st, 3rd, 5th...) and the sum of its even digits (2nd, 4th...) must be divisible by 11.

Calculation for the positive five-digit integer of the form ab,cba to be divisible by 11

Required 5 digit number is of the form, ab,cba

Using the divisibility test of 11, we get

(b + b) - (a + c + a) to be divisible by 11

i.e. 2b - (2a + c) to be divisible by 11

Replacing ab,cba using the greatest numbers, such as 7, 8 and 9 and checking its divisibility with 11

78,987 = 2*8 - (2*7 + 9) = 16 - (14 + 9) = 16 - 23 = -7 NO

87,978 = 2*7 - (2*8 + 9) = 14 - (16 + 9) = 14 - 25 = -11 YES

79,897 = 2*9 - (2*7 + 8) = 18 - (14 + 8) = 18 - 22 = -4 NO

97,879 = 2*7 - (2*9 + 8) = 14 - (18 + 8) = 14 - 26 = -12 NO

89,798 = 2*9 - (2*8 + 7) = 18 - (16 + 7) = 18 - 23 = -5 NO

98,789 = 2*8 - (2*9 + 7) = 16 - (18 + 7) = 16 - 25 = -9 NO

Thus, a positive 5-digit number is 87,978

Hence, the required positive five-digit integer of the form ab,cba; which should be divisible by 11 is 87,978

The approximate probability that out of 1000 poker hands there will be at least 450 with a single pair is 0.035

This is a binomial distribution problem with n = 1000 and p = 0.42. Let X be the number of poker hands with a single pair out of 1000 poker hands.

To find the probability that there are at least 450 poker hands with a single pair, we need to calculate P(X ≥ 450).

Using the normal approximation to the binomial distribution, we have:

μ = np = 1000 × 0.42 = 420

σ = √(np(1-p)) = √(1000 × 0.42 × 0.58) ≈ 16.08

Using the continuity correction, we can approximate P(X ≥ 450) as P(Z ≥ (449.5 - 420)/16.08) where Z is the standard normal distribution.

P(Z ≥ (449.5 - 420)/16.08) = P(Z ≥ 1.814) ≈ 0.035

Therefore, the approximate probability that out of 1000 poker hands there will be at least 450 with a single pair is 0.035.

Solving a system of equations we can see:

First, let's define the variables:

We can write the system of equations:

S = (3/4)*M

M = K - $18

S + M + K = $286.40

First, we can rewrite the second equation to get:

K = M + $18

Now we can replace the first and second equations into the third one:

(3/4)*M + M + (M + $18) = $286.40

Now we can solve this for M:

M*(1 + 1 + 3/4) = $286.40 - $18

M = $268.40*(4/11) = $97.60

Now we can find the other two values:

K = M + $18 =  $97.60 + $18 = $115.60

S =  (3/4)*M =  (3/4)*$97.60 = $73.20

CFSE = (2.73 × 10-19 J) / (1000 J/mol)

= 2.73 × 10-22 kJ/mol

The crystal field splitting energy (CFSE) can be calculated from the wavelength of maximum absorption.

The energy of a photon of light is proportional to its frequency (ν) and inversely proportional to its wavelength (λ).ν = c / λ

where,ν = frequency,

λ = wavelength,

c = speed of light in vacuum

The relationship between frequency (ν) and energy (E) is given by:

E = hν

where,

E = energy of a photon of light,

h = Planck's constant

The absorption of light in transition metal complexes is due to the promotion of an electron from a lower energy orbital to a higher energy orbital.
Therefore, the energy of the photon of light absorbed (E) must be equal to the energy difference (ΔE) between the two orbitals.
ΔE = hc / λwhere,

ΔE = energy difference,

h = Planck's constant,

c = speed of light in vacuum,

λ = wavelength of maximum absorptionThe crystal field splitting energy (CFSE) is equal to the energy difference between the d orbitals of a transition metal ion that are split in energy due to the presence of ligands around the ion.
Therefore,CFSE = ΔE

where,ΔE = energy difference calculated above
Therefore, the crystal field splitting energy (CFSE) for the [CrCl6]3- ion is:

CFSE = ΔE

= hc / λ= (6.626 × 10-34 Js) × (2.998 × 108 m/s) / (735 × 10-9 m)

= 2.73 × 10-19 J
The value of the CFSE can be converted from joules to kilojoules per mole (kJ/mol).1 J = 1 kg m2 s-21 kJ/mol

= 1000 J/mol

Therefore,CFSE = (2.73 × 10-19 J) / (1000 J/mol)

= 2.73 × 10-22 kJ/mol

Answer:

16 cans per minute

Step-by-step explanation:

Its simple 80 divided by 5 is 16 so ever minute 16 cans are packed.

The ratio of the cans to minutes is 80 : 5 or 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.

A machine can pack 80 cans in 5 minutes.

let's denote the number of cans with X and

Time with T

So we have to find the value of X : T

X = 80 and

T = 5 minutes

X : T = 80 : 5  or

X : T = 16 : 1   (divide by 5 on both sides)

It means the machine can pack 16 cans per minute.

Thus, the ratio of the cans to minutes is 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.
