Answer:

He received $320

Step-by-step explanation:

It's $10 less than  half of last year so we add 10 to 150 which give 160 *2 (because it was half) and we get $320(the amount he got last year) All, in all this kids parents are losing money.

Answer:

The answer is $320

Step-by-step explanation:

This year, Arthur received $150 for his birthday, which is $10 less than half the amount he received last year.

So, half of the amount of money he received last year was $150+$10 = $160.

In order to find the money Arthur received last year, this number has to be multiplied by 2.

Arthur received $160*2 = $320 in total.

Using the Divergence Theorem to compute the net outward flux of the following field across the given surface  the net outward flux of the vector field F across the surface S is -36π.

To compute the net outward flux across the given surface S using the Divergence Theorem, we need to evaluate the surface integral of the dot product between the vector field F and the outward unit normal vector dS over the surface S. The Divergence Theorem relates this surface integral to the volume integral of the divergence of the vector field over the region enclosed by the surface.

Let's denote the surface S as the sphere with equation x² + y² + z² = 9. The outward unit normal vector dS for a sphere can be expressed as (x, y, z)/r, where r is the radius of the sphere.

First, we need to compute the divergence of the vector field F. Taking the divergence of F yields:

div(F) = ∂(−9y - x)/∂x + ∂(−4x - 2y)/∂y + ∂(−7y - x)/∂z

      = -1 - 2 - 0

      = -3.

According to the Divergence Theorem, the net outward flux across the surface S is equal to the volume integral of the divergence of F over the region enclosed by the sphere. Since the sphere completely encloses the region, the volume integral reduces to a simple computation over the sphere.

Using the divergence -3 and the surface area of a sphere 4πr², where r is the radius, which is 3 in this case, we can calculate the net outward flux:

Net outward flux = ∫∫∫V div(F) dV

               = -3 * ∫∫∫V dV

               = -3 * (4/3)π(3^3)

               = -3 * (4/3)π * 27

               = -36π.

Therefore, the net outward flux across the surface S is -36π.

Step-by-step explanation:

The answer to questions are as follows- a)720 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once. b)240 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once, containing the block cd. c)120 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once, that start with the letter f.d)4 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once, that contain the blocks abc and ef.

a) To find the number of strings that can be formed using the letters a, b, c, d, e, f with each letter used formerly, we need to find the number of permutations of the letters. This can be set up using the formula for permutations of n objects taken r at a time, which is n!/( n- r)!.

In this case, we've 6 objects and we want to take all 6, so we have

6!/( 6- 6)! = 6! = 720

thus, there are 720 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly.

b) To find the number of strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that contain the block cd, we can treat the block cd as a single object and find the number of permutations of the performing 5 objects( alphabet, e, f, and the block cd). We also multiply this by the number of ways that cd can be arranged within the string( which is 2 since cd can be arranged as cd or dc).

So we have

5! * 2 = 240

thus, there are 240 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, containing the block cd.

c) To find the number of strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that starts with the letter f, we can fix f as the first letter and also find the number of permutations of the remaining 5 objects. This can be set up using the formula for permutations of n objects taken r at a time, which is n!/( n- r)!.

In this case, we've 5 objects and we want to take all 5, so we have

5!/( 5- 5)! = 5! = 120

thus, there are 120 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that start with the letter f.

d) To find the number of strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that contain the blocks alphabet and ef, we can fix alphabet and ef as blocks and find the number of permutations of the remaining 2 objects( d and f). We also multiply this by the number of ways that the blocks can be arranged within the string( which is 2 since alphabet can be before ef or ef can be before the alphabet).

So we have

2 * 2! = 4

thus, there are 4 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that contain the blocks alphabet and ef.

The solution to the equation cos(x + 2π/3) = √2/2 over the interval

(0, 2π) is [7π/12, 3π/4]

A periodic function has a range that is determined for a fixed interval and a domain that includes all real number values.

Any function that has a positive real integer p such that f (x + p) = f (x), with all x being real values, is said to be periodic.

The given function is cos(x + 2π/3) = √2/2 over the interval (0, 2π).

(x + 2π/3) = cos⁻1(√2/2).

x + 2π/3 = π/4  or 21π/12   (As cos is +ve on I and IV)

Now,

x + 2π/3 = π/4.

x = π/4 - 2π/3.

x = (3π - 8π)/12.

x = - 5π/12.

x = π - 5π/12.

x = (12π - 5π)/12.

x = 7π/12.

And,

x + 2π/3 = 21π/12.

x = 21π/12 - 2π/2.

x = (21π - 12π)/12.

x = 9π/12.

x = 3π/4.

Therefore, it will take approximately 13.7 years for the population to double.

a. To determine the growth rate, you need to calculate the percentage increase in population. The formula for growth rate is:

Growth Rate = (New Value - Old Value) / Old Value * 100

Using the given values, we have:

Growth Rate = (1577 - 1500) / 1500 * 100
Growth Rate = 77 / 1500 * 100
Growth Rate ≈ 5.13%

b. To write a general equation for the population, you can use the formula:

p(t) = p(0) * (1 + r/100)^t

where p(t) is the population at time t, p(0) is the initial population, r is the growth rate, and t is the number of years.

c. To estimate the population in 2010, we need to find the population at time t = 2010 - 2000 = 10 years. Using the general equation from part b, and substituting the given values:

p(10) = 1500 * (1 + 5.13/100)^10
p(10) ≈ 1500 * (1.0513)^10
p(10) ≈ 1500 * 1.6436
p(10) ≈ 2465.4

Therefore, the estimated population in 2010 is approximately 2465.

d. To find out how many years it will take for the population to double, we need to solve the equation:

2 * p(0) = p(0) * (1 + r/100)^t

Simplifying the equation, we have:

2 = (1 + r/100)^t

Taking the logarithm of both sides, we get:

log(2) = t * log(1 + r/100)

Finally, solving for t, we have:

t = log(2) / log(1 + r/100)

Substituting the growth rate from part a, we have:

t = log(2) / log(1 + 5.13/100)
t ≈ log(2) / log(1.0513)
t ≈ 13.7 years

Therefore, it will take approximately 13.7 years for the population to double.

Rounding up to the nearest whole number, you would need to survey approximately 753 randomly selected air passengers to be 90% confident that the sample percentage is within 3.5 percentage points of the true population percentage.

To determine the sample size needed for estimating a population percentage with a specified margin of error and confidence level, we can use the formula for sample size calculation for proportions. The formula is:

n = (Z^2 * p * (1-p)) / E^2

Where:

n is the required sample size,

Z is the Z-score corresponding to the desired confidence level (for a 90% confidence level, Z ≈ 1.645),

p is the estimated population proportion (since we don't have an estimate, we can use 0.5 for maximum sample size),

E is the desired margin of error (in decimal form).

In this case, the desired margin of error is 3.5 percentage points, which is 0.035 in decimal form.

Plugging in the values, we have:

n = (1.645^2 * 0.5 * (1-0.5)) / 0.035^2

Calculating this expression gives us:

n ≈ 752.93
