Answer: x = 3

Step-by-step explanation:

-3 +9x = 24

9x= 24+3

9x=27

9x/9= 27/9

x=3

Answer:

x = 3

Step-by-step explanation:

-3 + 9x = 24

rearrange:

9x - 3 = 24

Add 3 to both sides of the equation:

9x - 3 + 3 = 24 + 3

9x = 27

Divide both sides by 9:

9x/9 = 27/9

x = 3

If there were only twenty-two students instead of fifty-two who contributed their moms' heights and we wanted to use a one-sample confidence interval procedure (whether it would be z or t), we would have had to assume that the population of mom-heights was normally distributed.

The one-sample confidence interval is used to estimate the true population mean based on a sample mean and standard deviation. The procedure assumes that the sample is a random sample from a normally distributed population. With a sample size of at least 30, the central limit theorem allows for the use of a z-test to construct the confidence interval. With a smaller sample size, a t-test would be more appropriate. However, the assumption of normality still needs to hold for the validity of the confidence interval.

If the sample size is smaller than 30, the assumption of normality can be replaced by the assumption of approximately normal data. This means that the data follows a distribution that is symmetric and bell-shaped, even if it is not exactly normal.

However, the validity of the confidence interval can be compromised if the data is highly skewed or contains outliers. In such cases, it may be necessary to use non-parametric methods to construct a confidence interval.

Because the graph is starting high and going down, your answer is c- exponential decay

Answer:

This is exponential decay.

Step-by-step explanation:

Lets break down the answers:

A: Linear Growth. Well, we can eliminate this because the line is going down, its decay. Also, linear means line, a straight line.

B: Exponential Growth. This might work, but then again, it says *growth* not decay. Exponential is correct because as the values get bigger and bigger, the line curves.

C: Exponential Decay. Yes! This is exactly what we need. Exponential because of the curve... and of the decay.

D: Linear Decay. No, linear, again, is for lines. But now, we have already eliminated it because it says linear.

The value of a(t) is -1 and b(t) is 55 + \(e^t\)

No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.

In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.

For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:

μ(t) = e^∫a(t)dt

To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.

To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).

Comparing the given equation with the standard form, we can identify:

a(t) = -1

b(t) = 55 + \(e^t\)

Therefore, The value of a(t) is -1 and b(t) is 55 + \(e^t\)

It will take B 8 hours to travel in order to overtake A.

The relationship among the distance, time and speed can be expressed by using the relation.

\(\mathbf{speed = \dfrac{distance}{time}}\)

In this kind of ratio relation, it is pertinent to understand that, the rise in a variable cause a decrease in the other, where the third variable is constant.

Here:

From the given relation:

So, we can have a table expressing the parameters given in the question as follows:

A          4            t+2     4t + 8

B          5             t         5t

Equating both distance together, we have:

4t + 8 = 5t

Ciphers, such as the enigma machine, that rearrange the sequence of characters based on a fixed rule are known as substitution cipher.

A type of encryption known as a replacement cypher employs a key to substitute certain plaintext chunks with the ciphertext in a predetermined manner.

Single letters, pairs of letters, triplets of letters, combinations of the aforementioned, etc. are all acceptable "units." The receiver decodes the text using the inverse substitution technique to ascertain what the original message was.

Cyphers for transposition and substitution are similar. In a transposition cypher, the plaintext's units are not changed; instead, they are rearranged in a brand-new, frequently extremely complex pattern. A substitution cypher modifies the units themselves while preserving the order of the units from the plaintext in the ciphertext.

The substitution cypher can take many different shapes. If a cypher only functions with single letters, it is referred to as a simple substitution cypher; a polytrophic cypher, on the other hand, functions with larger groups of letters.

Answer:

275 yards of ribbon need to be ordered

Step-by-step explanation:

Figure out how much ribbon, in inches, is needed altogether by multiplying the amounts of ribbon by how many boxes are expected to sell for both box sizes:

Small Boxes:

20 in • 225 boxes = 4500 in of ribbon needed

Large Boxes:

30 in • 180 boxes = 5400 in of ribbon needed

Add it up to see how much you need:

4500 + 5400 = 9900 in of ribbon needed in total

There are 36 inches in 1 yard, so divide 9900 by 36 to see how many yards need to be ordered:

9900 ÷ 3 = 275 yards

(Alternatively, you could divide 9900 by 12 inches in a foot to get 825 feet. Then you would divide 825 by 3 feet in a yard to get 275 yards)

The predicted temperature to the nearest degree fahrenheit, at 9 p.m. is 75  degree fahrenheit.

Given the equation that expresses the temperature, in degrees fahrenheit, in London during a day in august as;

t(x) = 9sin(0.4x - 4) + 74,

where;

x is the number of hours after midnight.

If the time is 9pm after midnight, the total number of hours will be 21 hours

Substitute x = 21 into the function to have;

t(21) = 9sin(0.4(21) - 4) + 74

t(21) = 9sin(4.4) +74
t(21) = 9(0.0767)+74

t(21) = 74.69 degree fahrenheit,

Answer:

76.8

Step-by-step explanation:

1. We assume, that the number 31.25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 31.25, so we can write it down as 100%=31.25.

4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.

5. Now we have two simple equations:

1) 100%=31.25

2) x%=24

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=31.25/24

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24 is what percent of 31.25

100%/x%=31.25/24

(100/x)*x=(31.25/24)*x       - we multiply both sides of the equation by x

100=1.3020833333333*x       - we divide both sides of the equation by (1.3020833333333) to get x

100/1.3020833333333=x

76.8=x

x=76.8

now we have:

24 is 76.8% of 31.25

The family need to earn $4000 per month, so that exactly 30% of their  monthly income is $12000 per month

It is recommended that families should not spend more than 30% of there income on mortgage payments.

Consider the income as x

The percentage of income = 30%

The 30% of income = $1200

Then the equation will be

The 30% of income  = The total income × 30% of the income

Substitute the values in the equation

1200 = x × (30/100)
1200 = x × 0.3

x = 1200 / 0.3

x = $4000

Hence, the family need to earn $4000 per month, so that exactly 30% of their  monthly income is $12000 per month

The length and width of the rectangle is 27 inches and 13 inches, respectively.

Let the width be w inches and the length be l inches

According to the question, length of the rectangle is 12 less than 3 times the width of the rectangle

=> l = 3w - 12

=> 3w - l = 12      -   eq 1

The perimeter of the rectangle is also given as 40.

We know, perimeter of a rectangle is equal to twice the sum of the length and width of the rectangle.

=> 2 (l + w) = 40

=> l + w = 20

=> w + l = 20      -   eq 2

Adding eq 1 and eq 2, we get

4w = 32

=> w = 8

Substituting the value of w in any of the two equations, we get

l = 12
