Answer:

MAD = 1.333 Pounds

Step-by-step explanation:

The first step is to find the , mean of the data 6, 4, 8, 7, 8, 9

\mu= \frac{6 + 4 + 8 + 7 + 8 + 9}{6}\\\\\mu = 7

Now we find the difference between each data x_i and the mean . |\mu-x_i|

| 7-6 | = 1\\\\| 7-4 | = 3\\\\| 7-8 | = 1\\\\| 7-7 | = 0\\\\| 7-8 | = 1\\\\| 7-9 | = 2

Now we add all the difference and then we divide the result between the data number n=6:

MAD = \frac{1 + 3+ 1 + 0 +1 +2}{6}

MAD = 1.333 Pounds

This value means that the average difference between the weight of each bag and the average weight of the bags is 1,333 pounds.

The mean deviation represents a measure of how scattered the data are with respect to the mean. That is, the DMA measures how much the weight of a bag differs from the average weight of the 6 bags

irga5000 [103]

Answer:

v = 220 yd²

Step-by-step explanation:

Small portion

v = 5 * 4 * 3

v = 60 yd²

Large portion

v = 9 * 6 * 3

v = 162 yd²

Total

v = 60 + 162

v = 220 yd²

1. SIMPLIFY EACH EXPRESSION:
natka813 [3]

Answer:

1. 8x2 - 7x + 4x3 - 2-3x2 + 9x - 4 = 16+2x

Step-by-step explanation:

1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)

2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)

Bringing us to the answer → <u>16 + 2x!</u>

1. Trapezoid BEAR has a height of 8.5 centimeters and parallel bases that measure 6.5 centimeters and 11.5 centimeters. To the n
e-lub [12.9K]
<h3>Given</h3>

1) Trapezoid BEAR with bases 11.5 and 6.5 and height 8.5, all in cm.

2) Regular pentagon PENTA with side lengths 9 m

<h3>Find</h3>

The area of each figure, rounded to the nearest integer

<h3>Solution</h3>

1) The area of a trapezoid is given by

... A = (1/2)(b1 +b2)h

... A = (1/2)(11.5 +6.5)·(8.5) = 76.5 ≈ 77

The area of BEAR is about 77 cm².

2) The conventional formula for the area of a regular polygon makes use of its perimeter and the length of the apothem. For an n-sided polygon with side length s, the perimeter is p = n·s. The length of the apothem is found using trigonometry to be a = (s/2)/tan(180°/n). Then the area is ...

... A = (1/2)ap

... A = (1/2)(s/(2tan(180°/n)))(ns)

... A = (n/4)s²/tan(180°/n)

We have a polygon with s=9 and n=5, so its area is

... A = (5/4)·9²/tan(36°) ≈ 139.36

The area of PENTA is about 139 m².

If f(x)= x*2 +3 and g(x) = 4x + 1, what is f(g(2))?
enot [183]

Answer:

f(g(2))=84

Step-by-step explanation:

Step one:

Given data

f(x)= x*2 +3

g(x) = 4x + 1

Step two

Let us find g(2) first then we proceed to find f(g(2))

g(2)=4(2) +1

g(2)=8+1

g(2)=9

Since g(2)=9

f(g(2))=x*2 +3

f(g(2))=9*2 +3

f(g(2))=81+3

f(g(2))=84

The sum of 25 and x is 48 find x. . Solve.
ahrayia [7]

Answer:

x = 23

Step-by-step explanation:

Sum of 25 and x = 48

25 + x = 48

Subtract 25 from both sides

25 - 25 cancels out

48 - 25 = 23

We would be left with x = 23
