Answer:

Step-by-step explanation:

There are two functions (f & g), each of which have a table of inputs and outputs.  The same list of inputs is given to both functions, but the outputs are different.

Imagine that you asked your Father 6 questions, (weirdly instead of numbered 1 through 6, numbered -3 through 2), and that he gave you a list of answers.

Imagine that you asked your Grandfather the same 6 questions, and you got a list of answers from him.

On which question did they give the same answer?

It was on question number "1", (really the 5th question, but as we've numbered things from -3 to 2, it's question "1").

Since the "questions" were the input, "x", x=1.

The probability that a value selected at random from this distribution is greater than 31 is essentially 1.

Since the mean of the normal distribution is 31 and the standard deviation is 3, we know that the distribution is centered around 31 and the values are spread out within a range of approximately 3 units on either side of the mean. To find the probability that a value selected at random from this distribution is greater than 31, we need to look at the area under the curve to the right of 31.

Using a z-score table or a calculator, we can find that the z-score for 31 in this distribution is 0. This means that 31 is exactly at the mean of the distribution. To find the area under the curve to the right of 31, we need to find the area between 31 and positive infinity in terms of standard deviations from the mean.

Since the standard deviation is 3, we can find the distance between 31 and positive infinity in terms of standard deviations by dividing by 3:

(infinity - 31) / 3 = infinity/3 - 31/3 = infinity - 10.33

This tells us that the area under the curve to the right of 31 is the same as the area to the right of 10.33 standard deviations above the mean. However, since the normal distribution is continuous and extends infinitely in both directions, the area to the right of any finite value is essentially 1 (i.e. the probability of selecting a value greater than any specific value is essentially 100%).

Answer:

x = 16.5

Step-by-step explanation:

The best way to solve this is to use cross multiplication.

\(\frac{3}{x} = \frac{4}{22}\)

4 * x = 4x

22 * 3 = 66

Your equation is 66 = 4x.

Divide both sides by 4.

66/4 = 16.5

4x/4 = x.

Answer: Let's call Sarah's original amount of money as x. Then, Christine had 0.8x.

After they spent $684 altogether, Christine had 0.8x - 0.25(0.8x) = 0.8x - 0.2x = 0.6x left.

Sarah had x - 684.

Since Christine had thrice as much money left as Sarah, we can write an equation:

0.6x = 3(x - 684)

Expanding the right side of the equation:

0.6x = 3x - 2052

Solving for x:

2.6x = 2052

x = 787.69

So Sarah originally had 787.69 dollars and spent 787.69 - 684 = 103.69 dollars.

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

The length of the garden is 15 meters

The breadth of the garden is 10 meters

From the question, we have the following parameters that can be used in our computation:

Length = 5 + Breadth

So, we have

Perimeter = 2 * (5 + Breadth + Breadth)

The permeter is 50

So, we have

2 * (5 + Breadth + Breadth) = 50

This gives

(5 + Breadth + Breadth) = 25

So, we have

Breadth + Breadth = 20

Divide by 2

Breadth = 10

Recall that

Length = 5 + Breadth

So, we have

Length = 5 + 10

Evaluate

Length = 15

Hence, the length of the garden is 15 meters

In (a), we have

An itemized deduction of $500 with a 36 percent tax rate would reduce a person's taxes by $180.

Itemized deductions reduce a taxpayer's taxable income by the total of the deductions. The amount of tax savings is calculated by multiplying the deduction by the taxpayer's marginal tax rate.

The marginal tax rate is the tax rate paid on the last dollar of taxable income. According to the problem, the tax rate is 36 percent. This indicates that for every dollar earned in taxable income, 36 cents must be paid in taxes.

To calculate the tax savings, we need to multiply the $500 deduction by the 36 percent tax rate:

$500 x 0.36 = $180

Therefore, an itemized deduction of $500 with a 36 percent tax rate would reduce a person's taxes by $180.

Total work done = Work done in interval (i) + Work done in interval (ii) + Work done in interval (iii). Total work done = qE * Δx(i) + qE * Δx(ii) + qE * Δx(iii)

To determine the work done on a positive point charge, we need to know the electric field and the displacement of the charge. Since you haven't provided the electric field, we'll assume it's a constant field of magnitude E.

(i) To find the work done on the charge between x=0 and

x=2nm, we need to calculate the force experienced by the charge and multiply it by the displacement. The force experienced by a positive charge in an electric field is given by F = qE, where q is the charge. The displacement is given by Δx = 2nm - 0.

The work done is given by W = F * Δx

= qE * Δx.

(ii) Similarly, for the second interval between x=2nm and

x=4.5nm, we calculate the force experienced by the charge using

F = qE, where q is the charge, and the displacement is

Δx = 4.5nm - 2nm.

The work done is given by W = F * Δx

= qE * Δx.

(iii) For the third interval between x=4.5nm and

x=6.5nm,

we use F = qE to calculate the force experienced by the charge and

Δx = 6.5nm - 4.5nm for the displacement.

The work done is given by W = F * Δx

= qE * Δx.

(iv) To find the total work done between x=0

and x=6.5nm, we sum up the work done in each interval:

Total work done = Work done in interval (i) + Work done in interval (ii) + Work done in interval (iii)

Total work done = qE * Δx(i) + qE * Δx(ii) + qE * Δx(iii)

Total work done = Work done in interval (i) + Work done in interval (ii) + Work done in interval (iii). This calculation assumes a constant electric field of magnitude E and that the charge remains positive throughout the intervals. Hence, Total work done = qE * Δx(i) + qE * Δx(ii) + qE * Δx(iii).

To determine the total work done on a positive point charge between x-0 and x-6.5nm, we need to calculate the work done in each interval and then sum them up.

(i) For the interval between x-0 and x-2nm, the work done is given by:

Work done in interval (i) = qE * Δx(i),

where q is the charge, E is the magnitude of the constant electric field, and Δx(i) = 2nm - 0.

(ii) For the interval between x-2nm and x-4.5nm, the work done is given by:

Work done in interval (ii) = qE * Δx(ii),

where Δx(ii) = 4.5nm - 2nm.

(iii) For the interval between x-4.5nm and x-6.5nm, the work done is given by:

Answer:

24.25 years

Step-by-step explanation:

We know that average of a set = (sum of all terms) / (number of terms). Right now, we know two things: the average of the set (21 years) and the number of terms in the set (5). Therefore, we can rewrite the equation to solve for the sum of all terms.

We have: 21 = \(\frac{sum}{5}\)

sum = 21 · 5 = 105

Now we know the sum of ages of the 5 girls. We want to find the average age of the 4 remaining girls when we take out the girl who is 8 years old. As previously stated, to find the average of a set, we need to know two things: the sum of all terms in the set and the number of terms in the set. Right now, we only know one of those things: the number of terms in the set, which is 4. To find the sum, we can simply subtract the 8-year-old girl's age from the sum of ages of the 5 girls, which would be 105 - 8 = 97.

Therefore, the average age of the 4 remaining girls is \(\frac{97}{4} = 24.25\) years.

Hope this helps!

Answer:

24.25

Step-by-step explanation:

Since the average of 5 girls is 21, there total age is 105 (21*5)

If one of them is 8, 105-8 is 97 and 97/4 (because there is 4 girls left) is 24.25
