Answer:

median- 58.5

first quartile- 56

third quartile- 65

interquartile range- 9

Step-by-step explanation:

median is when you put the numbers from least to greated and find the middle number; so, you will put this set in that order= 38, 46, 55,56,58,59,61,65,67,75. now, you get stuck between 58 and 59. so you add them and divide by two to get 58.5. thats the median. The first quartile is any number from the set that is smaller than the median, basically the first half of it. now you will just find the median of that which is 56. that is your first quartile. third quartile is the second half of the set, any number in the set that is greater than the median. you will find the median of that half to get 65. that is your 3rd quartile. interquartile range ius the difference bewteen your first and third quartile. 65-56 is 9. hope this helped marck as brainlyest and help me with my que tooo :)

For the graph find a) b) c) and d)

Whitepunk [10]

Answer:

$f(0) = -1$

$f(\pi) = 1$

Domain: All real numbers

$Range = [-1,1]$

Step-by-step explanation:

Given

The attached graph

Solving (a): f(0)

On the attached graph

$f(x) = -1$ when $x =0$

So:

$f(0) = -1$

Solving (b): f(pi)

On the attached graph

$f(x) = 1$ when $x =\pi$

So:

$f(\pi) = 1$

Solving (c): Domain

There is no restriction on x.

Hence, the domain is the set of all real numbers

Solving (d): Range

In the attached graph

$y_{min} = -1$

$y_{max} = 1$

So, the range is:

$Range = [-1,1]$

Which equation below can be used to determine the missing angle in the triangle?

Sedaia [141]

Answer:You can use this fact to solve for the missing angle of a triangle. ... Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees. ... Let x = the degree measure of each angle.

The graph of the parent function p(x)=x^2 passes through the point E (21,184). The graph p is transformed such that the new grap

NemiM [27]

The new coordinates of E are (13 , 179)

Step-by-step explanation:

Let us revise some transformation

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

∵ p(x) = x²

∵ The graph p is transformed such that the new graph represents

the function f(x)

∵ f(x) = (x + 8)² - 5

∴ x of p(x) is add by 8 and p(x) subtracted by 5

- By using the 2nd and 4th rule above

∴ The graph of p(x) is translated 8 units left and 5 units down

∵ Point E (21 , 184) lies on the graph of the parent function p(x)

∴ Point p translated 8 units to the left and 5 units down

- That means subtract 8 from its x-coordinate and 5 from its

y-coordinate

∴ The new coordinates of E = (21 - 8 , 184 - 5)

∴ The new coordinates of E = (13 , 179)

The new coordinates of E are (13 , 179)

What is the result of rotating the triangle 90° counterclockwise around the point (2, -1)?

NARA [144]

Answer:

(0, 2) -> (-1, -3)

(1, 5) -> (-4, -2)

(3, 1) -> (0, 0)

Step-by-step explanation:

The general rule for a rotation 90° counterclockwise around the origin if you have a point (x, y) -> (-y, x). But since this isnt around the origin. You need to do a simple step before applying the rule.

To each point you want to rotate you need to substract the point that is the center of the rotation.

The points of the triangle are:

(0, 2)

(1, 5)

(3, 1)

Now you have to substract (2, -1) to each of them

(0, 2) - (2, -1) = (-2, 3)

(1, 5) - (2, -1) = (-1, 6)

(3, 1) - (2, -1) = (1, 2)

And with the new points you apply the rule for rotation (x,y) -> (-y,x)

(-2, 3) -> (-3, -2)

(-1, 6) -> (-6, -1)

(1, 2) -> (-2, 1)

And now you add the previously substracted point (center of rotation).

(-3, -2) + (2, -1) = (-1, -3)

(-6, -1) + (2, -1) = (-4, -2)

(-2, 1) + (2, -1 = (0, 0)
