Answer: - 1.3

Step-by-step explanation: I believe that it's -1.3 if you're referring to the arithmetic mean.

(1) Take the sum of -9, -5, -4, -4, -2, 0, 1, 2, 3, 5 and simplify it to -13

(2) Count the number of terms in the data set.

{-9, -5, -4, -4, -2, 0, 1, 2, 3, 5}

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10} - The number of terms in the data set is <u>10.</u>

(3) Divide the sum by the number of terms and simplify.

-13 / 10 = -1.3 (simplified)

On a boat tour in New York Harbor, Samuel views the Statue of Liberty. He knows from a brochure that the statue is 93 meters tal

Natasha2012 [34]

From the given provided, we can form a right triangle as shown in the attached diagram. Since we have the statue's height and the angle formed between the top of the boat and the statue we can use the properties of the tangent function below.

$\tan \theta = \frac{opposite}{adjacent}$
$\tan(26.3) =\frac{93}{A}$
$A = \frac{93}{\tan(26.3)}$
$A = 188$

From this, we can see that the side adjacent to the angle has a measurement of 188 m. This is actually the distance between boat and the base of the statue.

Answer: 188 m

Please help area and perimeter of functions

nalin [4]

Answer:

= 150 square units

Step-by-step explanation:

Area of a right triangle is given by the formula;

1/2 bh ; where b is base and h is the height of the triangle

using Pythagoras theorem, we can find the height;

h² = 20² - 16²

h = √144

= 12 units

The base of the small triangle can also be found using Pythagoras theorem;

b² = 15² - 12²

b = √ 81

= 9

Therefore;

Area = 1/2 bh

= 1/2 × 12 × (16+9)

= 1/2 × 12 × 25

= 6 × 25

= 150 square units or 150 u²

RideAnS [48]

Answer:

Multiply the first equation by 18; multiply the second equation by 18; add the equations.

Multiply the first equation by − 6; multiply the second equation by 4; add the two equations.

Multiply the first equation by 3; multiply the second equation by − 2;add the two equations.

Step-by-step explanation:

All of these procedures work because they are canceling out the x and y values in both equations.
