Answer:

1st question: $-4.5

2nd question: 32

3rd question: -27

Step-by-step explanation:

1st question:

Alan's octopus is $-7 dollars right now. After reloading $50 dollars in, it just means that he put $50 dollars in. We can work it out like this:

-7+50=43 (you can switch the equation around but the sign has to go with it: 50-7)

Now Alan's octopus has $43 in it. It then says that Alan spends $48.5 for a really expensive pencil case. You can calculate it like this:

43-48.5=-4.5 (43-48.5 is the same as 43.0-48.5 and you can work it out on a number line).

This leaves Alan's octopus to only have $-4.5 which means he is in debt again.

2nd question:

I can make it out that it says: Tony adds -18 to +50. Find the results (I hope I saw it right). The equation of it would look like:

-18+50 or you can flip it around but the sign has to go with them like in question one which will look like this: 50-18=32. So the result of Tony's problem is 32.

3rd question:

Patty subtracts +11 from -16. Find the results.

First of all don't do this 11-16 because that would be 16 subtracted from 11 which is wrong because 1, the sign completely disappears unless you make it -16 plus 11 and 2, it's order would be incorrect. The correct equation should look like this:

-16-11=-27 ( -16-(+11) positive combined with negative is negative).

You can think of it like this: If it's the same sign that's addition or subtraction eg. -4-2 or +6+8, you just add it up together and put the sign in front which you would not have to do for the addition one unless you are asked to.

I hope you find this helpful!

The measure of the angle can be found by solving the equation

x = 5(180 - x) - 660.

Let's assume the measure of the angle is x. The supplement of the angle is 180 - x since they are supplementary angles.

According to the given information, the measure of the angle is 660 less than five times its own supplement. Mathematically, we can represent this as

                                          x = 5(180 - x) - 660

To solve this equation, we first distribute 5 to 180 - x, resulting in

                                                      900 - 5x

Then we can simplify the equation as follows: x = 900 - 5x - 660. Combining like terms, we get 6x = 240. Dividing both sides by 6, we find that x = 40.

Therefore, the measure of the angle is 40 degrees.

In inferential statistics, the objective is to determine the probability of the alternative hypothesis being true or the null hypothesis being true.

This involves using sample data to make inferences and draw conclusions about a larger population. By analyzing the data and performing statistical tests, we assess the likelihood of the alternative hypothesis or the null hypothesis being accurate.

The alternative hypothesis represents a claim or statement that contradicts the null hypothesis and suggests that there is a significant relationship or difference between variables. To determine its probability, statistical methods such as hypothesis testing and p-values are employed. These methods evaluate the strength of evidence against the null hypothesis and support the alternative hypothesis when the evidence is substantial.

To find the probability that exactly k out of the next n months have sales greater than 100, you can use the binomial probability formula:

P(k successes in n trials) = (n choose k) * p^k * (1-p)^(n-k)

where p is the probability of success in a single trial, and n choose k is the binomial coefficient, which is equal to n!/(k! * (n-k)!).

To use this formula, you first need to determine the values of p and n. The value of p is the probability that a single month's sales will be greater than 100. To find this probability, you need to know the mean and standard deviation of the normal distribution representing the monthly sales.

Once you have the values of p and n, you can plug them into the formula and compute the probability of exactly k successes in n trials.

For example, suppose the mean monthly sales are 80 and the standard deviation is 20. This means that the normal distribution representing the monthly sales has a mean of 80 and a standard deviation of 20. To find the probability that a single month's sales will be greater than 100, you can use the standard normal distribution table or a calculator to find the area under the curve of the standard normal distribution that is greater than 100. Suppose the result is 0.15. This means that the probability of a single month's sales being greater than 100 is 0.15.

Now suppose you want to find the probability that exactly 2 out of the next 3 months will have sales greater than 100. In this case, p is 0.15, k is 2, and n is 3. Plugging these values into the formula gives:

P(2 successes in 3 trials) = (3 choose 2) * 0.15^2 * (1-0.15)^(3-2)

= 3 * 0.15^2 * 0.85

= 0.3483

This is the probability that exactly 2 out of the next 3 months will have sales greater than 100.

Probability of doing something with the thirty percent chances twice is equal to 0.51.

As given in the question,

Percent chances of doing something is equal to 30%

Here, x value of 8 would be located on the left tail of the normal distribution curve, 3.67 standard deviations below the mean (μ=22.3) and with a very low value in terms of percentile or probability (0.015%).

To indicate where the given x value of 8 would be on the curve, we need to plot it on a normal distribution curve with a mean (μ) of 22.3 and a standard deviation (σ) of 3.9.
First, we need to convert the given x value of 8 into a z-score by using the formula:  z = (x - μ) / σ
Plugging in the values, we get: z = (8 - 22.3) / 3.9 = -3.67
This means that the value of 8 is located 3.67 standard deviations below the mean.
Next, we need to find this point on the normal distribution curve. We can use a z-score table or a graphing calculator to find the corresponding area under the curve.
If we use a z-score table, we can look up the area to the left of -3.67, which is 0.00015. This means that only 0.015% of the data falls below this point.
To plot this on the curve, we can locate the mean (μ) and mark it as the center of the curve. Then, we can count 3.67 standard deviations to the left of the mean and mark this as the point where the value of 8 would be located.

The total length of craft wire used by Samantha is 10x + 9

What is the scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

Let's call the length of the smaller quadrilateral's 6-centimeter side "x".

Then the length of the corresponding side in the larger quadrilateral would be 6+3=9 centimeters, since the scale factor is 3.

To find the total length of craft wire used, we need to add up the lengths of all the sides in both quadrilaterals.

The smaller quadrilateral has four sides, each with a length of x.

The larger quadrilateral also has four sides, but only one of them has a different length (9 cm), while the other three sides are simply 3 times longer than the corresponding sides in the smaller quadrilateral.

So the total length of craft wire used by Samantha is:

4x + 9 + 3x + 3x + 3x

Simplifying this expression, we get:

10x + 9

Hence,  the total length of craft wire used by Samantha is:

The area of the cone is:

We can find a using pitagoras:

The area is:

The answer is C.

Step-by-step explanation:

△ on the right hand side is a equilateral triangle

which means all interior angles are the same, which is 60°

for the overall triangle, thats a right angle on the top, which is 90° obviously

so because THAT right angle is formed by (4x-2)° and one of the interior angle from the equilateral triangle, which is 60°

so

90°=60°+(4x-2)°

30°=4x°-2° (Hi)

32°=4x°

x=8°

now for the △ on the left hand side is a isocelea triangle, which means two of its angle are the same

so that

(4x-2)°=(7y+9)° (Hi:Sub in (4x-2)°=30° into the equation)

30°=7y°+9°

21°=7y°

y=3°

Note that the depreciation for this vehicle using method 2 will be $340.

To calculate the depreciation using method 2, we need to multiply the cost of the car by the depreciation rate per mile, which is given in cents per mile.

First, we need to calculate the total depreciation for the car in cents by multiplying the miles driven by the depreciation rate per mile:

Total depreciation = Miles driven x Depreciation rate per mile

Total depreciation = 10,000 x 3.4 cents per mile

Total depreciation = 34,000 cents

Next, we need to convert the total depreciation from cents to dollars by dividing it by 100:

Total depreciation = 34,000 cents ÷ 100 cents/dollar

Total depreciation = $340

Therefore, the depreciation for this vehicle using method 2 will be $340.
