4. Marcos wants to paint his skateboard ramp shown below. What is the total surface area of the skateboard ramp?​

Step-by-step explanation:

step 1. a diagram is important and can be uploaded. you will get a quicker answer with a diagram

step 2. triangle RST is a right triangle so we can use trigonometry to find <S

step 3. the adjacent side of <S is ST and the hypotenuse is RS so we will use cos

step 4. cosS = adj/hyp = ST/RS = 2.7/4.9

step 5. <S = 56.6° using inverse cos.

Answer:

28 slices

Step-by-step explanation:

Take the length of the roll and divide by the size of the slice

10 1/2 ÷ 3/8

Change the mixed number to an improper fraction

(10*2 +1) /2 ÷ 3/8

21/2 ÷ 3/8

Copy dot flip

21/2 * 8/3

Rewriting

21/3 * 8/2

7 * 4

28

You will get 28 slices

I got

[tex]0.75 + 2\pi \times n[/tex]

[tex]5.28 + 2\pi \times n[/tex]

[tex]1 + 2\pi \times n[/tex]

5.53+2pi times n

WORK:

[tex](3 \sin(2x) + 3 \cos(2x) )) {}^{2} = 9[/tex]

[tex] \sin(2x) + \cos(2x) {}^{2} = 3[/tex]

[tex] \sin(x) + \cos(4 {x}^{2} ) = 3[/tex]

[tex]4 {x}^{2} + x = 3[/tex]

[tex]4 {x}^{2} + x - 3 = 0[/tex]

[tex](4x {}^{2} + 4x - 3x - 3 = 0[/tex]

[tex]4x(x + 1) - 3(x + 1) = 0[/tex]

[tex](4x - 3)(x + 1)[/tex]

Solve for x

[tex]4x - 3 = 0[/tex]

[tex]4x = 3[/tex]

[tex]x = \frac{3}{4} [/tex]

[tex]x + 1 = 0[/tex]

[tex]x = - 1[/tex]

While -1 is a solution, it isn't within the interval of 0,2pi.

However, we can use the reference angle identity

[tex] \cos(x) = \cos(x + 2\pi) [/tex]

So some more possible points are

[tex] - 1 + 2\pi[/tex]

Since it on a interval, it must be less than 2 pi or 6.28.

Let find some more points

[tex] - 1 + 2\pi = 5.28[/tex]

So 5.28 is a point,

[tex] \frac{3}{4} + 2\pi = 7.03[/tex]

That is too big since -6.28 is smaller than 7.03

We can use the identity

[tex] \cos(x) = \cos( - x) [/tex]

[tex] \cos( - 1) = \cos( 1 ) [/tex]

1 is smaller than 2pi so it is true.

[tex] \cos( \frac{3}{4} ) = \cos( - \frac{3}{4} ) [/tex]

Negative 3/4 is smaller than zero so it not a solution.

[tex]0.75[/tex]

[tex]5.28[/tex]

[tex] 1[/tex]

Make sure to include

[tex]2\pi \times n[/tex]

so

[tex]0.75 + 2\pi \times n[/tex]

[tex]5.28 + 2\pi \times n[/tex]

[tex]1 + 2\pi \times n[/tex]

We can also -3/4 plus 2 pi.

Which is about 6

5.53.

You would need to generate a deposit slip or utilize an electronic banking system to send the funds into your account to deposit $15.

A deposit slip is a little paper form that is included by a bank customer when depositing payments into a bank account.

To write a deposit of $15, you would need to create a deposit slip or use an electronic banking system to transfer the money into your account.

To write a deposit slip, you would need to follow these steps:

Obtain a deposit slip from your bank or financial institution, or use a deposit slip provided by your bank's mobile app.

Fill in your personal and account information, including your name, account number, and any other required information.

Indicate the amount of the deposit, in this case $15, in the designated area on the deposit slip.

If you are depositing checks or other negotiable instruments, list the details of each item in the designated area on the deposit slip, including the payee, check number, and amount.

Review the deposit slip for accuracy and completeness, and make any necessary corrections.

Submit the deposit slip and any accompanying cash or checks to a bank teller or use an ATM or mobile app to complete the deposit.

The test statistic  | t |  =4.45

Step-by-step explanation:

Step(i):-

Given that the first sample size n₁ = 36

Given that the second sample size n₂ = 34

Mean of the first sample x₁⁻ = 68.5

Mean of the second sample x₂⁻ = 70

Step(ii):-

Test statistic

       [tex]t = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S^{2} (\frac{1}{n_{1} }+\frac{1}{n_{2} } } )}[/tex]

     [tex]t = \frac{68.5-70}{\sqrt{2(\frac{1}{36}+\frac{1}{34} ) } }[/tex]

    [tex]t = \frac{-1.5}{0.337} = -4.45[/tex]

The test statistic  | t | = |-4.45| =4.45

The test statistic is given by t and t is calculated with the help of the test statistic formula. The value of t is 4.45.

The test statistic summarises the observation data into a unique number using central tendency, the variation, sample, and size in your statistical model.

The given information will be shown below.

The first sample size n₁ = 36

The second sample size n₂ = 34

The mean of the first sample x₁ = 68.5

The mean of second sample x₂ = 70

Then the test statistic will be given as

[tex]\rm t = \dfrac{x_1 - x_2}{\sqrt{S^2 (\dfrac{1}{n_1}+\dfrac{1}{n_1})}} \\\\\\\t = \dfrac{68.5 - 70}{\sqrt{2 (\dfrac{1}{36} + \dfrac{1}{34})}} \\\\\\t = \dfrac{-1.5}{0.337}\\\\\\t = -4.45[/tex]

The test statistic | t | = |–4.45| = 4.45

Answer:

The company's overall profits were 450,000.

Step-by-step explanation:

We know that Jerome received 150,000. This 150,000 also counts as 1/3 of the profit, so if we put it as an equation, it gives us this:

1/3x = 150,000  We need to work out how much the overall profits are, which I've labelled as x.

x = 450,000  Here we multiply 150,000 by 3 to get x on its own, or you could also divide by 1/3.

I hope this makes sense to you. ^-^ If not, do let me know.

Answer:

Mean: [tex]20.2[/tex], Median: [tex]20[/tex], Mode: [tex]18[/tex]

Step-by-step explanation:

The mean or average of a data set is calculating by dividing the sum of the data values by the number of the data values. In this case, the sum of the data values is [tex]18+24+20+18+21=101[/tex] and the number of data values is [tex]5[/tex], so the mean is [tex]\frac{101}{5}=20.2[/tex].

The median of a data set is the middle value when the data is ordered in ascending order, meaning least to greatest. Right now, the data is not in ascending order, but after ordering it, we get [tex]18,18,20,21,24[/tex]. Since there are [tex]5[/tex] data values in this set, the middle value, or median, will be the [tex]3[/tex]rd value, which, in this case, is [tex]20[/tex].

Finally, the mode of a data set is the most frequent value, or the value that shows up the most. In this case, [tex]18[/tex] shows up twice, unlike the other numbers, which only show up once, so we know that the mode is [tex]18[/tex]. Hope this helps!

56.12-9.85= $46.30

Answer:

0.85 pounds

Step-by-step explanation:

We start with a bag that weighs 4.75 pounds and want to find the weight of the pairs added to the bag.

Let x equal the weight of the pairs added to the bag.

We can write an equation containing 4.75 pounds and x, and solve for x to find this weight value.

We know that the final weight of the bag is 5.6 pounds, so we can substitute this value for y.

Subtract 4.75 from both sides of the equation.

The weight of the pairs added to the bag is 0.85 pounds.

Answer:

[tex]3\frac{2}{3} + 2\frac{2}{3} = 6\frac{1}{3}[/tex]

Step-by-step explanation:

Given

See attachment for number line

Required

Determine the model

From the attachment, we can see that each partition is 1/3

The gray rectangle covers 11 partitions.

So:

[tex]Gray = 11 * \frac{1}{3}[/tex]

[tex]Gray = \frac{11}{3}[/tex]

Express as a mixed number

[tex]Gray = 3\frac{2}{3}[/tex]

The black rectangle covers 8 partitions

So:

[tex]Black= 8 * \frac{1}{3}[/tex]

[tex]Black= \frac{8}{3}[/tex]

Express as a mixed number

[tex]Black= 2\frac{2}{3}[/tex]

So, the model is:

[tex]Gray + Black = Total[/tex]

Where Total is the point where the black rectangle stops

[tex]3\frac{2}{3} + 2\frac{2}{3} = 6\frac{1}{3}[/tex]

Good luck, I hope this helps :)

The first part where he mentions "The distribution is skewed right" is correct. The tail on the right hand side is pulled longer than it should be, or longer compared to the left tail. "Right skew" or "skewed right" is the same as "positively skewed". They all mean the same thing.

The portion where Maurice says "This implies that the mean is less than the median" is incorrect. This is where his error is located. The reason for the error is because it should be "The mean is greater than the median" when we have right-skewed data like this.

Here's one example to see why this is the case. Consider the distribution {1,2,3,4,5}. We can see that the median is 3 since it's directly in the center. The mean is also 3 since we add up all the values and divide by 5. Symmetric data has mean = median. Now, we'll replace the '5' with something much larger to get a large outlier. Let's say we have the set {1,2,3,4,55}. The median is still 3. The outlier doesn't pull on the median. However, the mean has changed and it is (1+2+3+4+55)/5 = 65/5 = 13. The mean went from 3 to 13. Therefore, mean > median here. The mean is affected by outliers. Think of it like the outlier is pulling on the mean in a sort of magnetic way. This outlier makes the mean larger than it should be. If the outlier is extreme enough, then it sometimes makes sense to consider the trimmed mean as opposed to the regular arithmetic mean. The trimmed mean is the mean of the main cluster of values ignoring the outlier(s).

-----------------------

To recap:

If we have right skewed data, then mean > median

As you can probably guess, if we had left-skewed data, then mean < median. In symmetric data, mean = median.
