Describe the graph of y=1/2x-10 compared to the graph of y=1/x

To find f(i), we will substitute i for x in the given function and simplify:

f(i) = (i^{26} + i^{24} + 2i^{22})/(i-1)
= ((i^{22})(i^4 + i^2 + 2))/(i-1)
= ((i^{22})(1 + (-1) + 2))/(i-1)
= ((i^{22})(2))/(i-1)
= (2i^{22})/(i-1)
= (2i^{22})/((-1)(1-i))
= (2i^{22})/((-1)(1-i)) * ((1+i)/(1+i))
= (2i^{22})(1+i)/((-1)(1-i)(1+i))
= (2i^{22})(1+i)/((-1)(1^2 - i^2))
= (2i^{22})(1+i)/((-1)(1 - (-1)))
= (2i^{22})(1+i)/(2)
= i^{22} + i^{23}
= i^{22}(1 + i)
= (i^{22})(1 + i)
= (1)(1 + i)
= 1 + i

Therefore, the answer is (d) (1+i).

Answer:

To find the values of a and b that make the power function y = ax^b pass through the points (2,5) and (6,9), we can use the following system of equations:

5 = a2^b

9 = a6^b

We need to solve for a and b in this system.

One way to do this is to divide the second equation by the first equation, which eliminates a and gives:

9/5 = (6/2)^b

Simplifying this gives:

9/5 = 3^b

Taking the logarithm of both sides (with any base) gives:

log(9/5) = log(3^b)

Using the logarithmic property that log(a^b) = b*log(a), we get:

log(9/5) = b*log(3)

Solving for b, we get:

b = log(9/5) / log(3)

Plugging this value of b into one of the original equations (e.g., the first one) gives:

5 = a*2^(log(9/5)/log(3))

Solving for a, we get:

a = 5 / 2^(log(9/5)/log(3))

Answer:

459 cases per 100,000 people.

Step-by-step explanation:

To calculate the prevalence of DMD, we need to know the number of people living with the condition at a specific point in time. We can estimate this number by multiplying the annual incidence rate by the average duration of the disease:

Prevalence = Annual incidence rate x Average duration of the disease

Annual incidence rate = 0.017% = 17 cases per 100,000 people per year

Average duration of the disease = 27 years

Therefore, the prevalence of DMD can be estimated as:

Prevalence = 17 cases per 100,000 people per year x 27 years = 459 cases per 100,000 people

So, approximately 459 people out of 100,000 are living with DMD. This can also be expressed as a percentage by multiplying the above value by 100, which gives:

Prevalence = 459 cases per 100,000 people x 100% = 0.459% of the population

Therefore, the prevalence of DMD is approximately 0.459% or 459 cases per 100,000 people.

For the equation y = 5, the slope of is obtained as option D: 0.

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

From the graph it can be seen that the line is for the function -

y = 5

So, the coordinate points are (0,5).

Write the equation in slope-intercept form y = mx + b.

Here m is the slope and b is the y-intercept.

So, this will be -

5 = m(0) + b

We can see that the value for m is 0.

Therefore, the slope value is 0.

The average percentage change in population in California from 2000-2009 is 1.35% and population in 2015 will be 39306963.

What is average?

In mathematics, the average is a value that represents the central or typical value in a set of numbers. There are several types of averages, including the mean, median, and mode.

The mean is the most commonly used type of average, and it is calculated by adding up all the numbers in a set and then dividing the sum by the total number of numbers. For example, the mean of the set {3, 5, 8, 12} can be calculated as:

mean = (3 + 5 + 8 + 12) / 4 = 7

Now,

To calculate average of percentage change from 2000-2009

we have to add percentage change for every year

and that will be = 1.97+1.71+1.65+1.42+1.22+1.02+1.07+1.22+0.93

=12.21%

then average=12.21/9=1.35%

hence,

          The average percentage change in population in California from 2000-2009 is 1.35%.

The population in 2015 will be = 37000000 + (1.35)⁶ × 37000000/100

The probability that the sample proportion will exceed 0.2983 is approximately 0.0708.

It is predicated on the likelihood that something will occur. The justification for probability serves as the basic foundation for theoretical probability. For instance, the theoretical chance of receiving a head while tossing a coin is half.

a) 0.28 percent of Canadians have green eyes. This ratio can be used to calculate the anticipated proportion of sample members who have green eyes:

Estimated number of green eyed individuals = Percentage of green eyed individuals * Sample size

Estimated population of those with green eyes: 600 divided by 0.28

168 persons with green eyes are anticipated.

As a result, we would anticipate that 168 members of the sample have green eyes.

b) The formula for calculating the sample proportion's standard deviation is:

Sample proportion's standard deviation is equal to sqrt[(p * (1-p)) / n].

where n is the sample size, and p is the percentage of people with green eyes (0.28). (600).

Sample proportion's standard deviation is equal to sqrt[(0.28 * (1-0.28)) / 600].

Sample proportion's standard deviation is 0.0258.

As a result, 0.0258 is the sample proportion's standard deviation.

c) We're looking for the likelihood that the sample proportion will be more than 0.2983. As the sample size is large enough to allow for the use of the normal approximation, we may use the conventional normal distribution to determine this probability.

Then, we must use the following formula to standardise the sample proportion:

z = [(P * (1 - P)] / sqrt[(p - P)]

where P is the population proportion (0.28), n is the sample size, and p is the sample proportion (0.2983) that we are interested in (600).

z = (0.2983 - 0.28) / sqrt[(0.28 * (1 - 0.28)) / 600]

z = 1.47

The chance of a standard normal variable reaching 1.47 can be calculated using a standard normal distribution table or calculator and is roughly 0.0708.

Thus, 0.0708 is about how likely it is that the sample proportion will be more than 0.2983.

Answer:

The fraction that is not equivalent to 25% is 2/5.

To see why, we can start by converting 25% to a fraction. Recall that "percent" means "per hundred," so 25% is equal to 25/100 or 1/4.

Now, we can check each of the answer choices to see if they are equivalent to 1/4:

1/4 is already in the form of 1/4, so it is equivalent to 25%.

5/20 can be simplified by dividing both the numerator and denominator by 5, which gives 1/4. So 5/20 is also equivalent to 25%.

25/100 is the same as 1/4 (we converted 25% to 1/4 earlier), so it is equivalent to 25%.

This leaves us with 2/5 as the answer choice that is not equivalent to 25%. We can see this by converting 2/5 to a percent:

2/5 = 0.4

0.4 x 100% = 40%

So 2/5 is equivalent to 40%, which is not the same as 25%.

Answer: [tex]2/5[/tex] second option

Step-by-step explanation: 1/4 is equal to 25% because if you multiply by 100 and divide by 4 that will equal 25. 5/20 simplified to 1/4 which we know is 25%, 25/100 also does too. Therefore, the answer is 2/5 because it simplifies to 40% which isn't 25%.

Option A is correct, the experimental probability of not selecting a diamond is 82.5%.

It is a branch of mathematics that deals with the occurrence of a random event.

The total number of cards drawn is 40, and the frequency of diamonds drawn is 7.

This means that the frequency of not selecting a diamond is:

40 - 7 = 33

So the experimental probability of not selecting a diamond is:

P(not diamond) = frequency of not selecting a diamond / total number of cards drawn

P(not diamond) = 33/40

P(not diamond) = 0.825

P(not diamond) = 82.5%

Therefore, the experimental probability of not selecting a diamond is 82.5%.

The quotient of (12x^(3)-9x^(2)-21x+22) divided by (3x-3) is 4x^2 + 6x + 7, and the remainder is 0.

To find the quotient, use long division. First, divide the highest degree term of the numerator by the highest degree term of the denominator: 12x3 ÷ 3x = 4x2. Multiply the denominator by the quotient, then subtract this product from the numerator:

12x3 - 3x(4x2) = 9x2 - 4x2 = 5x2.

Divide the highest degree term of the new numerator by the highest degree term of the denominator: 5x2 ÷ 3x = 5x. Multiply the denominator by the quotient, then subtract this product from the numerator:

9x2 - 3x(5x) = -21x - 15x = -36x.

Divide the highest degree term of the new numerator by the highest degree term of the denominator: -36x ÷ 3x = -12. Multiply the denominator by the quotient, then subtract this product from the numerator:

-21x - 3x(-12) = 22 - (-36) = 58.

Divide the highest degree term of the new numerator by the highest degree term of the denominator: 58 ÷ 3 = 19. Since the degree of the numerator is lower than the degree of the denominator, 19 is the remainder.

Therefore, the quotient of (12x3 - 9x2 - 21x + 22) divided by (3x - 3) is 4x2 + 6x + 7, and the remainder is 0.

The individual would need $405,840.13 at the start of retirement to make semiannual withdrawals of $15,265 for 35 years from an account paying 4.5% compounded semiannually.

What is the Present Value of an Annuity?

With a specific rate of return, or discount rate, the present value of an annuity is the current value of the future payments from an annuity. The present value of the annuity decreases as the discount rate increases.

To determine the amount needed for retirement, we can use the formula for the present value of an annuity:

  [tex]PV= PMT* \frac{1-\frac{1}{(1+r)^{n} } }{r}[/tex]

where PV is the present value, PMT is the payment amount, r is the interest rate per period, and n is the number of periods.

In this case, PMT = $15,265, r = 4.5%/2 = 0.0225 (since the interest is compounded semi-annually), and n = 35 x 2 = 70 (since there are 70 semiannual periods in 35 years).

Plugging in these values, we get:

[tex]PV = (15,265\times(1 - (1 + 0.0225)^{(-70))) / 0.0225[/tex]

PV = $405,840.13

Answer:

Yes, the perimeter and side length of a square are proportional. This is because a square has four equal sides, so if you increase the length of one side by a certain factor, the perimeter (which is the sum of all four sides) will also increase by the same factor. In other words, if you double the length of a side of a square, you will also double its perimeter. Similarly, if you reduce the length of a side by a certain factor, the perimeter will also be reduced by the same factor. This relationship holds true for all squares, regardless of their size or orientation.

The value of a when b = 8 and c = 5 is 41.351.

Jointly proportional refers to a relationship between two or more variables in which all of the variables increase or decrease together in the same ratio. For example, if one variable doubles, the other variables double as well.

The variable a is jointly proportional to b and the cube of c. This means that a = k*b*c^3, where k is a constant. We can use the given values to find k:

127 = k*6*8^3

127 = k*3072

k = 127/3072

k = 0.041351

Now we can use this value of k to find the value of a when b = 8 and c = 5:

a = 0.041351*8*5^3

a = 0.041351*8*125

So the probability of the cost being between $260 and $412 is 0.5953.

a. The probability that the cost will be $260 or less can be found by calculating the z-score and using a standard normal distribution table. The z-score is calculated as follows:

z = (x - μ)/σ

where x is the value we are interested in, μ is the mean, and σ is the standard deviation. In this case, x = 260, μ = 360, and σ = 88. So the z-score is:

z = (260 - 360)/88 = -1.14

Using a standard normal distribution table, we can find that the probability of the cost being $260 or less is 0.1271.

b. The probability that the cost will be more than $412 can be found by calculating the z-score and using a standard normal distribution table. The z-score is calculated as follows:

z = (x - μ)/σ

where x is the value we are interested in, μ is the mean, and σ is the standard deviation. In this case, x = 412, μ = 360, and σ = 88. So the z-score is:

z = (412 - 360)/88 = 0.59

Using a standard normal distribution table, we can find that the probability of the cost being more than $412 is 0.2776.

c. The probability that the cost will be between $260 and $412 can be found by subtracting the probability of the cost being $260 or less from the probability of the cost being $412 or less. Using the z-scores we calculated in parts a and b, we can find the probabilities from a standard normal distribution table:

P(x ≤ 260) = 0.1271
P(x ≤ 412) = 0.7224

P(260 < x < 412) = P(x ≤ 412) - P(x ≤ 260) = 0.7224 - 0.1271 = 0.5953
