2. The weights (in pounds) of three adult males are

160, 215, and 195. The standard error of the mean of

these three weights is

(a) 190. (b) 27.84. (c) 22.73. (d) 16.07. (e) 13.13.

Answers

Answer:

(d) 16.07

Step-by-step explanation:

Step 1

We find the mean

Formula = Sum of Terms/Number of Terms

= 160+ 215 + 195/3

= 570/3

= 190

Step 2

We find the Standard Deviation

We use the formula for Sample Standard deviation =

√Mean - x/n - 1

n = 3

= √[(160 - 190)² + (215 - 190)² + (195 - 190)²]/3 - 1

= √1550/3

= √775

= 27.83882181

Approximately = 27.84

Step 3

We find the Standard Error of the mean

The formula = Standard deviation/√n

= 27.84/√3

= 16.07

Option d is correct

Based on the information given, the standard error of the mean of these three weights is 16.07.

The mean of the numbers will be:

= (160 + 215 + 195)/3

= 190

The standard deviation will be approximately 27.84.

Lastly, the standard error will be:

= 27.84 × ✓3

= 16.07

Answer:

Scale factor = 3

Step-by-step explanation:

Using similar triangles

AT/AG = AB/AC

9/3 = x+10/3x-10

Cross multiply

3(x+10) = 9(3x-10)

Expand

3x+30 = 27x-90

3x-27x = -90 - 30

-24x = -120

x = 120/24

x = 5

For the larger triangle;

AC = 3x-10

AC = 3(5)-10

AC =15-10

AC = 5

AB = x+10

AB = 5+10

AB = 15

For the scale factor;

Since AT/AG = AB/AC

9/15 = 3/5

3*3/5*3 =3/5

Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3

The McDonald's Play Place is going to increase its ball pit size to allow for more fun! The ball pit was originally 10 feet by 12 feet. They have decided to increase each side by the same amount. Express the area of the new pit as a polynomial in simplest form.

Answers

Please note that I'm not 100% sure on this question!

Answer:

[tex]x^{2} + 22x + 120[/tex]

Step-by-step explanation:

The ball pit was originally 10 × 12 feet long, or a 120ft area.

We can express the areas of the side and bottom extensions as [tex]12x[/tex] and [tex]10x[/tex] respectively.

The corner adjacent to both extensions can be expressed as [tex]x^{2}[/tex].

We can put these numbers into a polynomial:

[tex]x^{2} + 12x + 10x + 120[/tex]

This polynomial can then be simplified.

[tex]x^{2} + 22x + 120[/tex]

Step-by-step explanation:

The three angles in a triangle measure 180°. So add the the 2 known angles 70° + 63° = 133. Then subtract it from 180° to get the unknown angle 180 - 133 = 47.

Now that we know the third angle is 47 we find which number that when multiplied by 11 and 3 is added to that number you get 47.

11×4+3 = 47

A shirt that is normally 19.95 is on sale for 20% off what is the sale price

Answers

Answer:

$15.96

Step-by-step explanation:

Sales price = $19.95

Discount = 20%

Amount paid = $19.95 - ($19.95*20%) = $19.95 - $3.99 = $15.96

Answer:

$15.96

Step-by-step explanation:

The sales price is $19.95. The discount is 20%.

$19.95 - ($19.95 × 20%)

$19.95 × 20% = $3.99

$19.95 - $3.99 = $15.96

Answers

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is rotated 90° counterclockwise, the new point is at A'(-y, x).

If a point A(x, y) is rotated 90° clockwise, the new point is at A'(y, -x).

If a point A(x, y) is rotated 180° counterclockwise, the new point is at A'(-x, -y).

If a point A(x, y) is rotated 270° counterclockwise, the new point is at A'(y, -x).

Polygon ABCD is defined by the points A(-4, 2), B(-2, 4), C(1, 3), and D(2, 2).

The coordinates of D′ if polygon ABCD rotates 90° counterclockwise to create A′B′C′D′ is D'(-2, 2)

The coordinates of C″ if polygon ABCD rotates 90° clockwise to create A″B″C″D″ is C"(3, -1).

the coordinates of A′′′ if polygon ABCD rotates 180° clockwise to create A′′′B′′′C′′′D′′′ is A''"(4, -2)

the coordinates of B″ if polygon ABCD rotates 270° counterclockwise to create A″B″C″D″ is B"(4, 2)
