What is the median of the data?

1 answer:

3 0

You need to order the data, so
11, 12, 13, 14, 14, 15, 17, 17, 18, 18, 18, 20
Then find the middle of the data. Because there are 12 data points, the median will lie between the two 6th placed numbers
The two numbers are 15 and 17, so work out the mean of them. (15+17)/2 = 16
So the answer is B. 16

Identify the arc length of TV in terms of π. (image is attached)

uranmaximum [27]

Use the formula of arc length that is
s = rθ
where s = arc length, r = radius, θ = angle (unit must be in radian)
Given r = 5 in and θ = 48°( π /180°) = (4/15)* π = 0.2667 π,
s = 5 in (0.2667π) = 1.333 π in

If the graph of the following parabola is shifted two units left and three units down, what is the resulting equation?

mafiozo [28]

Answer:

$x=-8\left(y+3\right)^2-2$

Step-by-step explanation:

Because the x and y have been reversed in this equation, shifting the parabola to the left will be outside of the exponent and shifting up and down will be inside with the exponent.

The equation becomes $x=-8\left(y+3\right)^2-2$ .

Where subtracting by 2 moves it two units to the left and adding by 3 moves it 3 units down.

mylen [45]

Answer:

x = 35 degrees.

Step-by-step explanation:

(x\°) + (20+x) \°=90\°

want to solve for solve for x

2x = 90 - 20

2x = 70

x = 70 / 2

x = 35 degree
