Hi there! Hopefully This helps!

<h2><em>Answer: The mean number of this data set is 43. The mean represents the average number of minutes Julio practiced on his trumpet for 6 days.</em></h2>

Explanation:

<u><em>To find the "mean" you need to count how many numbers are in the data set. Then add up all the numbers in the data set. </em></u>

In this case you have six numbers in the data set, and all the numbers added up together(21+30+39+43+58+67) are 258.

<u><em>After adding up all the numbers, divide them by how many numbers are in the data set.</em></u>

258/6 = 43.

<u><em></em></u>

Answer: Choice B

(x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)

=========================================================

Explanation:

When dilating with respect to the origin, any point of the form (x,y) moves to (kx, ky) for some real number k. The k is the scale factor.

Point C is at (-2,2). It moves to C ' (-5,5)

The jump from x = -2 to x = -5 is "times 5/2" since kx = (5/2)*(-2) = -5

The same scale factor is used when going from y = 2 to y = 5.

Both x and y coordinates are multiplied by 5/2 to move from (-2,2) to (-5,5)

Therefore, the dilation rule we use is (x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)

-----------

We could have these steps to confirm

(x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)\\\\(-2,2) \to \left(\frac{5}{2}*(-2),\frac{5}{2}(2)\right)\\\\(-2,2) \to (-5,5)\\\\

The length of the longer leg of a right triangle is 6 cm more than twice the length of the shorter leg. The length of the hypote
iragen [17]
Let x = the shorter leg
2x + 6 is the longer leg
2x + 9 is the hypotenuse

We now do the Pythagorean Theorem of a^{2}+b^{2} = c^{2}

x^{2} +  (2x+6)^{2} =  (2x+9)^{2}

Multiply out to get:

x^{2} +4 x^{2} +24x+36=4 x^{2} +36x+81

The 4 x^{2} will cancel out each other when you combine like terms to get all the terms on one side of the equal sign. 

Combine like terms with the rest to end with x^{2} -12x-45=0

Factor this to get (x-15)(x+3) = 0 then set each factor equal to zero. 

You end up with two solutions, x = 15 and x = - 3 HOWEVER distance cannot be measure in negatives so that answer will not work so x = 15. Now plug into our given information.

The short leg is 15 cm long.
The longer leg of 2(15) + 6 = 36 cm long
The hypotenuse of 2(15) + 9 = 39 cm long. 

You can check your answers by plugging them into the Pythagorean Theorem again.
