What is the reciprocal of x^3 and a^2

The value of y when x = 28 is y = 112. Since y is directly proportional to the value of x, we can write y = kx.

When a quantity 'p' is increasing with an increase in the other quantity 'q' or decreases with a decrease in 'q', both quantities are said to be directly proportional.

I.e., p ∝ q ⇔ p = kq

Where k is the proportionality constant.

It is given that, the value of y is directly proportional to the value of x.

I.e., y ∝ x

Then, y = kx

If x = 3.5 and y = 14, then k is

k = y/x = 14/3.5 = 4

So, if k = 4 and x = 28, then y is

y = kx = 4 × 28 = 112

Therefore, the value of y is 11.

Option C is the correct option for the given problem; let’s consider all options and identify the different reasons in the number list.

From the second element (index 1) through the last element, this procedure iterates through the list of numbers using a for loop. It determines whether the current number is lower than the previous number after each repetition. If it is, the process gives a prompt False response, meaning that the list is not growing.

The procedure returns True, indicating that the list is growing, if the for loop concludes without running into a number that is less than the number it encountered before.

According to the issue definition, this technique implies the list has at least two elements. This guarantees that the for loop will always have a previous number to compare to.

Answer:

Step-by-step explanation:

Let sharma age be S and Ankit age be A

S = 3a

(s-10) = 5(a-10)

substitute 1 in 2

3a-10 = 5a -50

40 = 2a

a = 20

a) The probability histogram of pmf for the number of students who show up for a professor's office hour on a particular day is shown below.

b) The probability that at least two students show up = 0.55 and the probability that more than two students show up = 0.25

c) The probability that between one and three students show up = 0.7

d) The probability that the professor shows up = 0.20

First we write the number of students who show up for a professor's office hour on a particular day and their pmf in tabular form.

x        p(x)

0       0.20

1       0.25

2       0.30

3       0.15

4       0.10

The probability histogram of this data is shown below.

The probability that at least two students show up would be,

P(x ≥ 2) = p(2) + p(3) + p(4)

P(x ≥ 2) = 0.30 + 0.15 + 0.10

P(x ≥ 2) = 0.55

Now the probbability that more than two students show up:

P(x > 2) = p(3) + p(4)

P(x > 2) = 0.15 + 0.10

P(x > 2) = 0.25

The probability that between one and three students show up would be:

P(1 ≤ x ≤ 3) = p(1) + p(2) + p(3)

P(1 ≤ x ≤ 3) = 0.25 + 0.30 + 0.15

P(1 ≤ x ≤ 3) = 0.7

And the probability that the professor shows up would be: p = 0.20

Step-by-step explanation:

To find the indicated function values for the function f(x) = (-x)^3 - x^2 - x + a, let's substitute the given values of x into the function.

a) f(0):

Substituting x = 0 into the function, we have:

f(0) = (-(0))^3 - (0)^2 - (0) + a

f(0) = 0 - 0 - 0 + a

f(0) = a

Therefore, f(0) = a.

b) f(5):

Substituting x = 5 into the function, we have:

f(5) = (-(5))^3 - (5)^2 - (5) + a

f(5) = -125 - 25 - 5 + a

f(5) = -155 + a

Therefore, f(5) = -155 + a.

c) f(-5):

Substituting x = -5 into the function, we have:

f(-5) = (-(-5))^3 - (-5)^2 - (-5) + a

f(-5) = 125 - 25 + 5 + a

f(-5) = 105 + a

Therefore, f(-5) = 105 + a.

d) f(2) + f(-2):

Substituting x = 2 into the function, we have:

f(2) = (-2)^3 - (2)^2 - (2) + a

f(2) = -8 - 4 - 2 + a

f(2) = -14 + a

Substituting x = -2 into the function, we have:

f(-2) = (-(-2))^3 - (-2)^2 - (-2) + a

f(-2) = 8 - 4 + 2 + a

f(-2) = 6 + a

Therefore, f(2) + f(-2) = (-14 + a) + (6 + a) = -8 + 2a.

To summarize:

a) f(0) = a

b) f(5) = -155 + a

c) f(-5) = 105 + a

d) f(2) + f(-2) = -8 + 2a.

Now let's move on to the second part of the question.

Using the provided table for the function h(x):

X | h(x)

6 | 3

0 | 3

6 | ?

a) h(-6):

Looking at the table, we don't have a value for h(-6).

b) h(6):

From the table, h(6) = 3.

c) For what values of x is h(x) = 6?

Looking at the table, there is no x value where h(x) equals 6.

Therefore:

a) h(-6) = N/A

b) h(6) = 3

c) For what values of x is h(x) = 6? None.

Finally, let's analyze the given statement regarding the functions f(x) and g(x):

f(x) | g(x)

-1 | -7

-7 | -1

-8 | -2

-2 | -8

The statement is: f(-1) - f(-2) = -2 - (-8) = -2 + 8 = 6.

The statement f(-1) - f(-2) = 6 is false because the actual result is 10, not 6.

Therefore, the correct choice is:

OB. False; f(-1) - f(-2) = 10.

1 standard deviation =  8 inches. the answer is OPTION E

We know that 99.7% of American men have heights between 5'0" and 7'0". Since height is normally distributed, we can use the empirical rule to estimate the standard deviation.

According to the empirical rule, 99.7% of the data falls within 3 standard deviations of the mean. Therefore, we can say that the range of heights from 5'0" to 7'0" is 3 standard deviations.

We can use this information to estimate the standard deviation as follows:

Range of heights = 7'0" - 5'0" = 2 feet

3 standard deviations = 2 feet

1 standard deviation = 2/3 feet

1 foot = 12 inches

Therefore, 1 standard deviation = 2/3 * 12 inches = 8 inches

So, our estimate of the standard deviation of the height of American men is 8 inches. Therefore, the answer is OPTION E in the given options.

Add 10 to each side x/3=18 Multiply by 3

Answer:

x/3 - 10 = 8

Step-by-step explanation:

It seems like you want me to provide an equation, so here it is:

10 less equates to "minus 10", or "10 minus". [-10]

Quotient refers to division, and "a number" can be replaced with a variable: x. This is our numerator. Our denominator is "3", as it states, "and 3". Finally, the "is" statement refers to equality, and we can replace this with the equal sign.

Putting these all together, you get the equation, x/3 - 10 = 8.

The probability that exactly two of the marbles are red depends on the total number of marbles and the number of red marbles in the set. Let's assume we have a set of 10 marbles and 4 of them are red.

We can use the binomial probability formula to calculate the probability of exactly two red marbles. This formula is: P(X=k) = (n choose k) * p^k * (1-p)^(n-k), where n is the total number of marbles, k is the number of red marbles, p is the probability of drawing a red marble and (1-p) is the probability of drawing a non-red marble. Using this formula, we get: P(X=2) = (10 choose 2) * (4/10)^2 * (6/10)^8 = 0.3024 or approximately 30.24%. Therefore, the probability that exactly two of the marbles are red is 0.3024 or 30.24%.

The mean, median, and mode are:

Mean = 10

Median = 8

Mode = 8

To find the mean, median, and mode of the given set of numbers: 5, 8, 18, 1, 14, 6, 8, 13, 8, 19, we can perform the following calculations:

Mean: The mean is calculated by summing up all the numbers and dividing by the total count of numbers.

Mean = (5 + 8 + 18 + 1 + 14 + 6 + 8 + 13 + 8 + 19) / 10

= 100 / 10

= 10

Therefore, the mean is 10.

Median: The median is the middle value when the numbers are arranged in ascending order. If there are an odd number of values, the median is the middle number. If there are an even number of values, the median is the average of the two middle numbers.

Arranging the numbers in ascending order: 1, 5, 6, 8, 8, 8, 13, 14, 18, 19

Since there are 10 numbers, the median is the average of the two middle numbers, which are the 5th and 6th numbers:

Median = (8 + 8) / 2

= 16 / 2

= 8

Therefore, the median is 8.

Mode: The mode is the number(s) that appear(s) most frequently in the set.

In this case, the number 8 appears three times, which is more than any other number.

Therefore, the mode is 8.
