Answer:

a) y = 11x

b) y = $660

Step-by-step explanation:

a) For 10 people is $110, so simply divide.

110/10 = $11 per person.

y = 11x

b) So using that, substitute 60 for x.

y = 11(60)

y = $660

The necessary equation in the case at hand will be 40x + 50 = P, where P represents the total number of pages read and x represents the number of hours read.

A mathematical equation compares two numbers or values to a meaningful word, for instance, 6 x 4 = 12 x 2.

An equation is employed when more than one factor needs to be considered in order to fully understand or describe a situation.

So, to answer the question:

Chole has read the first fifty pages of the book.

Every hour, he reads forty pages.

For more than x hours, he reads.

The equation will then be as follows:

40x + 50 = P

P is the total number of pages read, while x denotes the number of hours spent reading.

Therefore, the necessary equation in the case at hand will be 40x + 50 = P, where P represents the total number of pages read and x represents the number of hours read.

Here the relation between number of weeks and Cost can be formulated as 42 = 15+ 8x. By simplifying the equation we get x= 3.375. So you need to save for 4 weeks to get enough money to buy the hamster.

Here you are saving money to buy a hamster. We have to formulate an equation to find out the number of weeks you should save to obtain the money.

The cost of the hamster =  $42

Amount you have with you = $15

Amount you can save a week = $8.

Let the number of weeks is x

Then, the equation is

 42 = 15 + 8x

  8x = 42 -15

  8x = 27

    x = 27/8 = 3.375

Since it is the number of weeks, we could take only whole numbers. Here x is greater than 3. So the number of weeks to save the money to reach the target would be 4.

So by saving $8 for 4 weeks, you could buy the hamster.

Answer:

Step-by-step explanation:

Given the formula for the volume of a torus (v = πh(R + r)), you can isolate R by dividing both sides of the equation by πh(R + r), as follows:

v / (πh(R + r)) = R

πh(R + r) * R = v

R^2 = v / (πh(R + r))

R = √(v / (πh(R + r)))

So, R is the square root of the volume divided by πh(R + r).

In other words, altering the sampling distribution in this way increases the likelihood of making a type 1 error.

The arithmetic mean, arithmetic average, or simply the mean or average, is the sum of a collection of numbers divided by the number of numbers in the collection in mathematics and statistics. The collection is frequently a collection of results from an experiment, observational research, or survey.

Here,

The sampling distribution is a distribution of the values of a statistic (such as the mean or median) calculated from a set of sample data. It gives us information about how the statistic is likely to vary from sample to sample, and it is used in hypothesis testing to calculate the probability of observing certain results if the null hypothesis is true.

Filtering out all values below the mean has the effect of changing the shape, location, and spread of the sampling distribution. For example, if the original sampling distribution is normally distributed with a mean of 0 and a standard deviation of 1, filtering out all values below the mean would result in a new sampling distribution with a mean greater than 0 and a standard deviation smaller than 1.

When the sampling distribution is altered, for example by filtering out all values below the mean, it can have an effect on type 1 errors. Type 1 errors occur when we reject the null hypothesis when it is actually true.

The value of a1 in a geometric series for which Sn=21825, an=125, r=15 will be 5/9.

The formula for the nth term in a geometric series is given by:

an = a1 * r^(n-1)

Where a1 is the first term, r is the common ratio, and n is the number of terms.

We are given Sn, an and r, and we can use the formula for the sum of a geometric series to solve for n:

Sn = a1 * (1 - r^n) / (1 - r)

Substituting the given values, we get:

21825 = a1 * (1 - 15^n) / (-14)

Multiplying both sides by -14, we get:

-304350 = a1 * (1 - 15^n)

Since we are given that an = 125, we can substitute this into the formula for an and solve for n:

125 = a1 * 15^(n-1)

Substituting a1 = -304350 / (1 - 15^n) from the equation above, we get:

125 = -304350 / (1 - 15^n) * 15^(n-1)

Dividing both sides by 15^(n-1), we get:

125 * 15^(1-n) = -304350 / (1 - 15^n)

Multiplying both sides by (1 - 15^n), we get:

125 * 15^(1-n) * (1 - 15^n) = -304350

Expanding the right-hand side, we get:

125 * (15 - 15^n) = -304350

Dividing both sides by 125, we get:

15 - 15^n = -2434.8

Adding 15^n to both sides, we get:

15^n = 15 - (-2434.8) = 2449.8

Taking the natural logarithm of both sides, we get:

n * log(15) = log(2449.8)

Dividing both sides by log(15), we get:

n = log(2449.8) / log(15)

Since n is the number of terms, it must be a positive integer. The closest positive integer to this value is 3, so n = 3.

Finally, we can use the formula for an to find a1:

an = a1 * r^(n-1)

Substituting the given values and n = 3, we get:

125 = a1 * 15^(3-1)

Dividing both sides by 15^(3-1), we get:

125 / 15^2 = a1

Calculating, we get:

a1 = 125 / 15^2

= 125 / 225

= 5/9.

Answer:

  y = -3cos(πx/4) +3

Step-by-step explanation:

You want a possible trig function that describes the values in the given table.

Looking at the table, we find the minimum y-value is 0, and it corresponds to x=0 and x=8. This means the period (P) of the function is 8.

The maximum y-value is 6. This means the midline (M) of the function is 3, the average of the minimum and maximum: (0 +6)/2 = 3.

The amplitude (A) of the function is the difference between the maximum value and the midline value: 6 -3 = 3.

The sine and cosine functions both oscillate back and forth between a value of -1 and a value of +1. The cosine function has its maximum at x=0, but the function needed here will have a minimum at x=0. We can use the cosine function, but it needs to be reflected over the x-axis (or midline).

In general the trig function we're looking for will have the form ...

  y = Acos(2πx/P) +M

As discussed above, the value of A will need to be negative to reflect the function over its midline. For A=-3, M=3, P=8, the function is ...

  y = -3cos(2πx/8) +3

  y = -3cos(πx/4) +3

__

Additional comment

In the case where the extreme values (cosine) or the midline values (sine) are not at x=0, there is a "phase shift" involved. That is, the trig function will need to be translated horizontally to match values in the table. That translation is accomplished by adding or subtracting a value from x. Translation of the cosine function is not needed in this case.

The probability that a woman is having one child of each sex is 0.2548.

The probability of having two children of the same gender (either both girls or both boys) can be calculated by multiplying the probability of having a girl or a boy is (which is 1/2 or 0.5) by itself twice, as each child is independent of the other:

0.5 × 0.5 = 0.25 (probability of having either two girls or two boys)

Since the total probability of having two girls or two boys is 0.5048 as given in the question, the probability of having one child of each sex is: 0.5048 - 0.25 = 0.2548.

Therefore, the probability that a woman with two children has one child of each sex is 0.2548

Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.

Given:

Deselectric costs $11900 more than the Deswagon.

Unit cost:

Deselectric: $0.11 per mile.

Deswagon: $0.12 per mile.

Kweku drives about 18,000 miles a year.

That means

The cost for each car;

Deselectric: 18000 x 0.11 = $1980

Deswagon: 18000 x 0.12 = $2160

The more cost is,

= $2160 - $1980

= $180 of savings in a year.

Answer:

So the derivative of the function F(x) = x^2 - 1/x + 1 is F'(x) = 2x - (x - 1)/x^2.

Step-by-step explanation:

The derivative of the function F(x) = x^2 - 1/x + 1 can be found by using the limit definition of the derivative. The derivative is the rate of change of the function at a given point and it is calculated as:

F'(x) = Lim h=0 (x + h)^2 - 1/(x + h) + 1 - (x^2 - 1/x + 1)/h

Expanding the expression inside the limit and simplifying, we get:

F'(x) = Lim h=0 2xh + h^2 - (1 - hx)/(x + h)^2

Using L'Hopital's Rule, we get:

F'(x) = Lim h=0 2x + 2h - (x - 1)/(x + h)^2

As h approaches 0, the limit becomes:

F'(x) = 2x + 2(0) - (x - 1)/x^2 = 2x - (x - 1)/x^2

So the derivative of the function F(x) = x^2 - 1/x + 1 is F'(x) = 2x - (x - 1)/x^2.

Add 23 to both sides,

Subtract 6x from both sides,

            2x = 18

Divide both sides by 2,

              x = 18 ÷ 2

∠A = 8x - 23
