The equation that can be used to solve for RH is 25/9(DP-T) - 100

Given the formula for the dew point in degrees, Fahrenheit expressed as

To solve for the value of RH, we will make RH the subject of the formula;

Subtract T from both sides:

Multiply both sides by 25

25(DP - T) = 9(100 - RH)

25(DP - T) = 900 - 9RH

25(DP - T) - 900 = 9RH

RH = 25/9(DP-T) - 100

Hence the equation that can be used to solve for RH is 25/9(DP-T) - 100

a. Mixed cost - the cost per unit decreases with increase in units sold.

b. Variable cost - the expense increases with increase in units sold

c. Fixed cost - expense is constant with increase in units sold.

d. Fixed cost - cost is constant with increase in units sold.

e. Variable cost - cost increases with increase in units sold

f. Variable cost - cost increases with increase in units sold

g. Mixed cost- depreciation cost decreases with increase in units sold.

h. Fixed cost - cost is constant with increase in units sold.

i. Variable cost - cost increases with increase in units sold

j. Fixed cost- cost is constant with increase in units sold.

According to the given question;

Mixed costs: That has a high initial cost generally because they contain some fixed components and change in proportion because they contain some variable components.

Fixed costs: Costs that are consistent or constant are known as fixed costs.

Variable costs: These alter as the quantity of units changes.

(a) The price is fixed. This is because even while the price per unit fluctuates, the overall price does not. For instance, the total cost for 20 units is $720 ($36 x 20 units), and the total cost for 100 units is $720 ($7.2 x 100 units).

(b) The overall cost of the phone is mixed. On the basis of unit cost fluctuations, it may be claimed that the first 20 units have a fixed component and that subsequent 20 units have an equal distribution of fixed and variable costs.

(c) The price is vary. Supply costs are fixed regardless of quantity changes, and variable cost per unit is also fixed regardless of quantity changes that affect changes in the aggregate but not in the individual.

(d) The fact that the overall insurance cost remains constant as the quantity changes suggests that it is a fixed cost.

(e) Total salary expenses are mixed costs since they have a higher initial cost due to the inclusion of some fixed costs and ratio changes as a result of the addition of variable costs.

(f) Variable expenses, which rise in line with an increase in quantity, make up the entire cost of items sold.

(g) Depreciation is a fixed cost because, despite the fact that unit cost reduces as quantity increases, total cost remains constant.

(h) The total rent expense is constant despite changes in quantity, indicating that it is a fixed expense.

(i) The price of shopping bags is variable since the price and total fluctuate when the amount changes.

(j) Since individual unit expenses are constant per unit, the cost per unit of goods sold is variable.

\(5110, 5111, 5112\)

Step-by-step explanation:

Let \(x=\) first consecutive number

\(x + (x+1)+(x+2) = 15333\) (\(x\) is the first number, \(x+1\) would be the second consecutive number of the sequence, and \(x+2\) would be the third)

\(3x + 3 = 15333\)

\(3x = 15330\)

\(x = 5110\)

\(x+1 = 5110+1\)

C. 19a + 11b

Step-by-step explanation:

Distribute into the parentheses.

3(5a + b) + 4(a + 2b)

= 15a + 3b + 4a + 8b

Add like terms.

15a + 3b + 4a + 8b

19a + 3b + 8b

= 19a + 11b

Hope that helps.

Hey there!

“Simplify 3(5a + b) + 4(a + 2b)”

FIRST you have to DISTRIBUTE

3(5a + b) + 4(a + 2b)

3(5a) + 3(b) + 4(a) + 4(2b)

3(5a) = 15a

3(b) = 3b

4(a) = 4a

4(2b) = 8b

“15a + 3b + 4a + 8b”

SECOND: COMBINE your LIKE TERMS

P(X = 0) = 0.335 Probability = 0.335.The given formula for probability distribution is:P(X) = (n! / x! (n - x)!) * πx * (1 - π)n - xwhere, P = Probability X = Random variable, n = Total number of trialsπ = Probability of success. Let us consider the given probabilities:(a) For n - 5 and π = 0.16, what is P(X:0)?When n = 5 and x = 0, then n - x = 5.

Therefore,

P(X = 0) = (5! / 0! (5 - 0)!) * (0.16)0 * (1 - 0.16)5 - 0= (1 / 1) * 1 * 0.3277= 0.3277Round off the answer to four decimal places as needed.P(X = 0) = 0.3277.(b) For n 9 and x-0.50, what is P(X 8)?When n = 9 and x = 8, then n - x = 1. Therefore,P(X = 8) = (9! / 8! (9 - 8)!) * (0.50)8 * (1 - 0.50)9 - 8= (9 / 1) * 0.00390625 * 0.5= 0.0176.

Round off the answer to four decimal places as needed.P(X = 8) = 0.0176(c) For n 9 and -0.40, what is P(X-7)?When n = 9 and x = 7, then n - x = 2. Therefore,P(X = 7) = (9! / 7! (9 - 7)!) * (0.40)7 * (1 - 0.40)9 - 7= (36 / 1) * 0.0809856 * 0.027= 0.0807.

Round off the answer to four decimal places as needed.P(X = 7) = 0.0807(d) For n-6 and x-0.81, what is P(x-5)?When n = 6 and x = 5, then n - x = 1. Therefore,P(X = 5) = (6! / 5! (6 - 5)!) * (0.81)5 * (1 - 0.81)6 - 5= (6 / 1) * 0.3252718081 * 0.19= 0.3727Round off the answer to four decimal places as needed.P(X = 5) = 0.3727.

To determine the given probabilities, the probability distribution formula has been used. The formula used is:P(X) = (n! / x! (n - x)!) * πx * (1 - π)n - xWhere,P is the probability,X is the random variable,n is the total number of trials, andπ is the probability of success. The first probability is to calculate the probability for n - 5 and π = 0.16, what is P(X:0)?The value of x is zero, and n - x is 5. The formula is applied to get the probability, and it is rounded off to four decimal places as needed. The second probability is to calculate the probability for n 9 and x-0.50, what is P(X 8)?The value of x is 8, and n - x is 1. The formula is applied to get the probability, and it is rounded off to four decimal places as needed. The third probability is to calculate the probability for n 9 and -0.40, what is P(X-7)?The value of x is 7, and n - x is 2. The formula is applied to get the probability, and it is rounded off to four decimal places as needed. The fourth probability is to calculate the probability for n -6 and x-0.81, what is P(x-5)?The value of x is 5, and n - x is 1. The formula is applied to get the probability, and it is rounded off to four decimal places as needed.

Therefore, the probabilities for different values of n, x, and π have been calculated by using the probability distribution formula.

The inequality solves to r > 5

The graph has an open hole at 5, with shading to the right

===========================================================

Explanation:

6+9r is the same as 9r+6

We'll subtract 6 from both sides to undo the +6

9r+6 > 51

9r+6-6 > 51-6

9r > 45

Then we'll divide both sides by 9 to isolate r.

9r/9 > 45/9

r > 5

The entire time, the inequality sign stays the same.

The solution set involves anything larger than 5. So something like r = 7 would work while r = 2 does not.

Visually, we'll have an open hole at 5 on the number line. Shade to the right to indicate things larger than 5. The open hole tells the reader "do not include 5 as part of the solution set".

To use long division in polynomials, we follow steps similar to normal long division, but we look for the terms from higher degree to lower.

We are dividing:

By:

We want to multiply the divisor by some expression that will make the higher term equal to the higher term of the dividend. The higher term of the dividend is 4x³, to get to that, we can multiply the divisor by 2x²:

Now we have the same term, so we just substract what we have got from the dividend:

Notice that we don't have a third degree term anymore.

So, until now we have done:

- Multiplied the divisor by 2x²

- Got a remainder of -5x² + 3

Now, we just repeat with the remainder.

We want to multiply 2x - 1 so that the higher term is -5x², so we can multiply by -5x/2:

And we do the substraction:

So, now we have got:

- Multiplied the divisor by 2x² and then by -5x/2

- Got a remainder of -5x/2 + 3

Now, we repeat once more:

To get -5x/2, we multiply the divisor by -5/4:

And we substract from the remainder:

So, we have done:

- Multiplied the divisor by 2x² then -5x/2 then -5/4

- Got a remainder of 7/4

This means that th result of the division is:

And the remainder is:

But, the answer wants us to write what the dividend is equal to.

Let's write first in the division form:

Notice that we result is the quotient plus the remainder divided by the divisor.

If we multiply both sides by the divisor, we will get:

That is the answer.

100 same-day tickets were sold for the cost using equation.

To solve this problem, we can use a system of two equations with two variables. Let x be the number of advance tickets sold and y be the number of same-day tickets sold. Then we have:

x + y = 600   (equation 1: total number of tickets sold)
50x + 30y = 28000   (equation 2: total amount paid for tickets)

We can solve for x and y by using elimination or substitution. Here's one way to do it using substitution:
From equation 1, we have y = 600 - x. Substitute this into equation 2:

50x + 30(600 - x) = 28000

Simplify and solve for x:
50x + 18000 - 30x = 28000
20x = 10000
x = 500

So 500 advance tickets were sold. To find the number of same-day tickets, we can substitute x = 500 into equation 1:

500 + y = 600
y = 100

So 100 same-day tickets were sold.

Question 3: True

Question 4: False

Question 5: True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c.

This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

Question 3: If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c.

True

When the derivative of a function, f'(x), is negative at a point c, it indicates that the function is decreasing at that point. Additionally, if the second derivative, f''(x), exists and is negative at x = c, it implies that the graph of f(x) is concave down at that point.

Question 4: A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0.

False

A local extreme point of a polynomial function can occur when f'(x) = 0, but it is not the only condition. A local extreme point can also occur when f'(x) does not exist (such as at a sharp corner or cusp) or when f'(x) is undefined. Therefore, f'(x) being equal to zero is not the sole requirement for a local extreme point to exist.

Question 5: If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = c.

True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c. This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

The volume of the solid obtained by rotating the region enclosed by y=x², x=y² about the line x=−7 can be computed using the method of discs or washers via an integral.

The given region enclosed by y=x², x=y² can be represented as:

As we need to rotate the region about the line x = -7, then we need to perform the following transformation:

x = t - 7So, the region enclosed by y=x², x=y² can be represented as:

y = (t - 7)², t = y²

The limits of integration of the variable 't' will be a = 0 and b = 1

As we are using the method of cylindrical shells, then the volume of the solid obtained can be represented as:

V = 2π∫₀¹ (y)(t(y)) dy

where, (y)(t(y)) = (t - 7)²

The integral can be written as:

V = 2π∫₀¹ (t - 7)² dy

By substituting t = √y, we have the following:

dt/dy = 1/2y^(-1/2)

Therefore, the integral becomes:

V = 2π∫₀¹ (t - 7)²

dy= 2π∫₀¹ (√y - 7)²

dy= 2π∫₀¹ y - 14√y + 49

dy= 2π[(1/2)y² - (28/3)y^(3/2) + 49y] from 0 to 1

By substituting the limits of integration a = 0 and b = 1, we have:

V = 2π[(1/2) - (28/3) + 49] = 2π[97/6]

Therefore, the volume of the solid obtained is V = 97π/3 square units.

The first equation has to be the ratio of raisins to sunflower seeds. If r is raisins and p is sunflower seeds and there are 3 times as many raisins as sunflower seeds then the first equation must be 3r=p

The second equation should model the prices properly. Raisins are 1.5 per pound and sunflower seeds are 4 per pound, because of this we should have 1.5r (r being each pound of raisins) and 4p (p being each pound of sunflower seeds). From this we know the second equation must be 4p+1.5r=34

The probability that 8% or fewer of a random sample of 500 adults will be left-handed is approximately 0.246.

The probability that 8% or fewer of a sample of 500 adults will be left handed can be calculated using the binomial distribution. The binomial distribution models the probability of a certain number of successes in a fixed number of Bernoulli trials, where the probability of success remains constant.

In this case, the number of Bernoulli trials is 500 (the sample size), the probability of success is 10% (the percentage of left-handed adults in the population), and the number of successes is the number of left-handed adults in the sample (which we are trying to calculate the probability of).

We can use the binomial cumulative distribution function (CDF) to calculate the probability of 8% or fewer successes (left-handed adults in the sample). This is given by:

P(X <= 40) = binomial_cdf(500, 0.1, 40)

Where X is the number of left-handed adults in the sample.

Plugging in the values, we get:

P(X <= 40) = binomial_cdf(500, 0.1, 40) = 0.246
