Answer:

$120*.12= then add the answer to the money amount

Step-by-step explanation:

Answer:  120*1.12

The multiplier 1.12 represents the idea of increasing by 12%

This is because 100% + 12% = 1 + 0.12 = 1.12

For example, if you spend $100 this week and increase that by 12%, then you'll spend 100*1.12 = 112 dollars next week. Note how 12% of 100 is 12, which is the amount the budget goes up.

If there had been a 2% decrease in total receipts, the new deficit would be $361.08 billion.

If there had been a 2% decrease in total receipts, the new total receipts would be:

New total receipts = $2154 billion - (2% of $2154 billion)

New total receipts = $2154 billion - $43.08 billion

New total receipts = $2110.92 billion

The total outlays would remain the same at $2472 billion.

So, the new deficit would be:

New deficit = New total outlays - New total receipts

New deficit = $2472 billion - $2110.92 billion

New deficit = $361.08 billion

Therefore, if there had been a 2% decrease in total receipts, the new deficit would be $361.08 billion.

The expected number of households that paid between $50 and $70 is

168,100.

As, z-score, also known as the standard score, is a statistical measure that represents the number of standard deviations a particular data point is away from the mean of a distribution.

The formula to calculate the z-score for a data point "x" in a distribution with mean "μ" and standard deviation "σ" is:

z = (x - μ) / σ

First, let's calculate the z-scores:

For $50:

z1 = (50 - 65.43) / 9.22

For $70:

z2 = (70 - 65.43) / 9.22

Using a standard normal distribution table

P(z < z1) = P(z < (50 - 65.43) / 9.22)

P(z < z2) = P(z < (70 - 65.43) / 9.22)

Let's denote these probabilities as p1 and p2, respectively.

So, Expected number = Total number of households * (p2 - p1)

Substituting the given values:

Expected number = 261,500 (p2 - p1)

Now, z1 = (50 - 65.43) / 9.22 = -1.6729

z2 = (70 - 65.43) / 9.22 = 0.4952

So, the corresponding probabilities:

P(z < -1.6729) ≈ 0.0475

P(z < 0.4952) ≈ 0.6879

Expected number = 261,500 (0.6879 - 0.0475)

Expected number ≈ 261,500 x 0.6404

Expected number ≈ 167,100

The expected number of households is 168,100.

Option C is the correct answer.

We have,

To find the expected number of households that paid between $50 and $70, we need to calculate the z-scores for both values and then use the cumulative distribution function (CDF) of the normal distribution to find the probability.

Finally, we multiply this probability by the total number of households to get the expected number.

First, let's calculate the z-score for $50:

\(z_1\) = (\(x_1\) - μ) / σ

= (50 - 65.43) / 9.22

≈ -1.671

Next, let's calculate the z-score for $70:

\(z_2\) = (\(x_2\) - μ) / σ

= (70 - 65.43) / 9.22

≈ 0.495

Now, we can use the CDF to find the probability of the values falling between these z-scores.

\(P(X_1 < X < X_2) = P(z_1 < Z < z_2)\\= P(z < z_2) - P(z < z_1)\)

Using a standard normal distribution table or a calculator, we can find the corresponding probabilities:

P(z < -1.671) ≈ 0.0467

P(z < 0.495) ≈ 0.6868

Subtracting the two probabilities, we get:

P(-1.671 < z < 0.495) ≈ 0.6868 - 0.0467 ≈ 0.6401

Finally, we multiply this probability by the total number of households:

Expected number of households

= P(-1.671 < z < 0.495) * Total number of households

= 0.6401 * 261,500

≈ 167,587.15

Rounding this value to the nearest hundred, we get:

Thus,

The expected number of households is 168,100.

For accounting purposes, depreciation is an allocation of a cost of an asset.

Both depreciation and amortization are techniques for spreading out an asset's cost throughout its useful life, although they are employed for various asset categories. Whereas amortisation is used for intangible assets like patents, copyrights, and trademarks, depreciation is utilised for tangible assets like buildings, machinery, and equipment. Depreciation is a method used to account for an asset's decline in value as a result of damage or obsolescence. During the course of the asset's useful life, the asset's cost is distributed to match the income it produces.

The given sequence is bₙ = 4n ln (1 + 1/n).

To determine the limit of the sequence bₙ using L'Hospital's rule, we follow the steps given below:

Step 1: We have to find the limit of the sequence bₙ in the given form.

That islimₙ→∞bₙ= limₙ→∞[4n ln(1 + 1/n)]

Step 2: We will simplify the above expression to get an indeterminate form 0/0 using the formula n ln (1 + 1/n) = ln [(1 + 1/n)^n].Therefore, limₙ→∞bₙ= limₙ→∞[4 ln(1 + 1/n)^n] / [1/(4n)]

We can rewrite the above expression as below using the exponential function. limₙ→∞bₙ= 4 limₙ→∞ [(1 + 1/n)^n]^(4/n)

Step 3: We evaluate the limit on the right-hand side of the above equation.

It is known as e^(limₙ→∞ (4/n)*ln(1+1/n)).Therefore, limₙ→∞bₙ= 4*e^(limₙ→∞ (4/n)*ln(1+1/n))The above limit is of the form 0 * ∞.

We can apply L'Hospital's rule for this case. We take the natural logarithm of the denominator and numerator and differentiate with respect to n.

We can write the new limit as below,limₙ→∞ (4/n)*ln(1+1/n)=limₙ→∞ (ln(1+1/n)/n)/(1/n^2)

Answer:

y= 2200 (3/4)x

Step-by-step explanation:

You can model a real-world situation involving an initial value and a constant growth or decay factor with an exponential equation in the form y=a(b)x, where b>0 and b≠1.

The constant a represents the initial value. It is the y-value of the equation when x=0.

The constant b represents the growth or decay factor.

When the equation models exponential growth, b>1.

When the equation models exponential decay, 0<b<1.

An exponential equation in the form y=a(b)x can model the value of the machine, y, x years after purchase. To write the equation, first look for phrases in the problem that tell you about the initial value, a, and the growth or decay factor, b.

Tessa is opening Tessa's Terrific Tees, her own custom T-shirt business. She bought a T-shirt printing machine that is currently valued at $2,200. The machine loses  1/4 of its value every year.

The constant a is the initial value. The initial value of the machine is $2,200. So, a=2,200.

The constant b is the decay factor, since the value of the machine is decreasing. The machine loses 1/4 of its value each year. In other words, the value of the machine each year will be 1–1/4= 3/4

times the value the year before. So, b= 3/4.

The exponential equation y= 2200 (3/4)x models the value of the machine.

An exponential equation in the form y=a(b)x that can model the value of the machine, y, x years after purchase is y= 2200*14*x

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0. In mathematics, a linear equation is an equation that may be put in the form \({\displaystyle a_{1}x_{1}+\ldots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}}\) are the coefficients, which are often real numbers.

Given that;

The cost of tshirt printing machine= $2200.

The lose of machine= 14

Now,

Substituting all the values in equation y=a(b)x

a=2200

b=14

y=2200*14*x

Given a ladder leaning against a building with a 73° angle, we can find the height of the building using h = 5 * tan(73°) and the length of the ladder using L² = h² + 5².

(a) In the sketch, draw a vertical line to represent the building. Mark the base of the building and the base of the ladder 5 meters apart. Draw the ladder leaning against the building at an angle of 73 degrees with the ground. The top of the ladder should align with the top of the building.

(b) Label the height of the building as 'h.' Using the tangent function, we can express tan(73°) as h/5. Solving for h, we have h = 5 * tan(73°). Use a calculator to find the value of tan(73°), then multiply it by 5 to determine the height of the building.

(c) To find the length of the ladder, we can use the Pythagorean theorem. The ladder serves as the hypotenuse of a right triangle, with the height of the building (h) as one side and the base of the ladder (5 meters) as the other side. The length of the ladder (L) can be found using the equation L² = h² + 5². Substitute the value of h you found in part (b) and solve for L.

correct me if I'm wrong

the solution is x = 4 and y = -2. To solve using elimination method,

we want to eliminate one of the variables (either x or y) by multiplying one or both equations by a suitable number such that the coefficients of the variable become the same in both equations.

Then we can subtract or add the equations to eliminate that variable.

Let's begin by eliminating x:

Multiplying equation (ii) by 2, we get:

2(x - 2y) = 2(8)

2x - 4y = 16

Now we have two equations:

2x + 3y = 2

2x - 4y = 16

Subtracting the second equation from the first, we get:

(2x + 3y) - (2x - 4y) = 2 - 16

7y = -14

Dividing both sides by 7, we get:

y = -2

Now we can substitute y = -2 into either equation (1) or (2) to solve for x. Let's use equation (2):

x - 2(-2) = 8

x + 4 = 8

x = 4

Therefore, the solution is x = 4 and y = -2.

The critical value that should be used in constructing the confidence interval is 1.645.

We are constructing a 90% confidence interval, so the alpha level is 1 - 0.90 = 0.10. The z-score that corresponds to an alpha level of 0.10 is 1.645.

We can find the critical value using the following steps:

1. We can look up the z-score in a z-table.

2. We can use a statistical calculator to find the z-score.

The following is the z-table for a two-tailed test with an alpha level of 0.10:

```

z-score | Probability

------- | --------

1.645 | 0.9500

```

As we can see, the z-score that corresponds to an alpha level of 0.10 is 1.645.

We can also use a statistical calculator to find the z-score. For example, in Excel, we can use the following formula:

```

What is compound interest?

The principal as well as the interest that has accrued over the previous period are both used to compute interest. Compound interest factors the principal into the calculation for determining the interest for the subsequent month, in contrast to simple interest, which does not. In mathematics, the symbol for compound interest is typically the letter C.I.

We are given the principal amount as $790 paying an interest rate of 6.9% compounded continuously.

The final balance is $2,550.
