The weights of 5 girls are 70 pounds, 68 pounds, 85 pounds, 62 pounds, and 70 pounds. Nina finds measures of center and measures

of variation of this data. Match the descriptions to the type of measure.
1. She found the difference of the least
and the greatest values.

2. She found the middle value after
arranging all the values from least
to greatest.

3. She added all the values and divided the
sum by 5.

4. She found the value that appeared the
most often.

5. She found the difference of the
upper quartile and the lower
quartile.

6. She found the mean and then
found the average deviation of
the weights from the mean.

The Measure of center or measure of variation of the weights are; Range = 23 pounds; Median = 70 pounds; Mean = 71 pounds; Mode = 70 pounds

<h3>How to find the measures of Central Tendency?</h3>

We are given the weights as;

Weights of 5 girls = 70 pounds, 68 pounds, 85 pounds, 62 pounds, and 70 pounds

1) The difference of the least and the greatest values is;

Range = 85 - 62 = 23 pounds

2)  The middle value after arranging all the values from least to greatest is; 62, 68, 70, 70, 85

Median = 70

3) Adding all the values and dividing by 5 is;

Mean = (62 + 68 + 70 + 70 + 85)/5

Mean = 71 pounds

4) Value that appeared the most is;

Mode = 70

Use Newton’s Method to find the solution to x^3+1=2x+3 use x_1=2 and find x_4 accurate to six decimal places. Hint use x^3-2x-2=
luda_lava [24]

Let f(x) = x^3 - 2x - 2. Then differentiating, we get

f'(x) = 3x^2 - 2

We approximate f(x) at x_1=2 with the tangent line,

f(x) \approx f(x_1) + f'(x_1) (x - x_1) = 10x - 18

The x-intercept for this approximation will be our next approximation for the root,

10x - 18 = 0 \implies x_2 = \dfrac95

Repeat this process. Approximate f(x) at x_2 = \frac95.

f(x) \approx f(x_2) + f'(x_2) (x-x_2) = \dfrac{193}{25}x - \dfrac{1708}{125}

Then

\dfrac{193}{25}x - \dfrac{1708}{125} = 0 \implies x_3 = \dfrac{1708}{965}

Once more. Approximate f(x) at x_3.

f(x) \approx f(x_3) + f'(x_3) (x - x_3) = \dfrac{6,889,342}{931,225}x - \dfrac{11,762,638,074}{898,632,125}

Then

\dfrac{6,889,342}{931,225}x - \dfrac{11,762,638,074}{898,632,125} = 0 \\\\ \implies x_4 = \dfrac{5,881,319,037}{3,324,107,515} \approx 1.769292663 \approx \boxed{1.769293}

Compare this to the actual root of f(x), which is approximately <u>1.76929</u>2354, matching up to the first 5 digits after the decimal place.

A department store buys 400 shirts at a cost of $7 200 and sells them at a selling
noname [10]

Answer:

down below.

Step-by-step explanation:

20 × 400 = 8000

8000 - 7200 = 800

therefore the % mark up is 10%, because 10% of 8000 is 800.

800 + 7200 = 8000
