When results from a scholastic assessment test are sent to test-takers, the percentiles associated with their scores are also gi

hram777 [196]

Answer:

The correct option is (D).

Step-by-step explanation:

Percentiles are statistical measures that are used to interpret data. It represents the data value which is more that a specific percentage of the data set.

The <em>n</em>th percentile of a data set is the value that is more that <em>n</em>% of the data set.

⇒ It is provided that a test-taker's score was at the 94th percentile for their verbal grade.

This statement implies that the test taker scored a mark more than 94% of the other test-takers, i.e. he\she performed better than 94% of the other test-takers in the verbal grade.

⇒ Also the test-taker's score was at the 16th percentile for their quantitative grade.

This implies that the test taker scored a mark more than 16% of the other test-takers, i.e. he\she performed better than 16% of the other test-takers in the quantitative grade.

Thus, the correct option is (D).

Which circles have an area of 36pift2?

san4es73 [151]

Area=pi times radius^2
area=36pi
36pi=pi times radius^2
divide both sides by pi
36=radius^2
square root both sides
6=radius

2radius=diameter
2 times 6=12
radius=6
diamater=12

the answers area A and D
(if you know your radius and diameter, you would know that diameter is 2 times radius and you could eliminate 2 choices imedietly (B and C))

y-1/6x+5=0 Is this written in standard form if not then what is the equation in standard form. A.yes B.no;y=1/6x-5 C.x=-6y+30 D.

trasher [3.6K]

Answer:

Step-by-step explanation:

Not in standard form. The coefficients should be integers and the coefficient of x should be positive.

x+6y=30

Note that the choices given are not in standard form.

Create a sequence with a pattern rule of "add ." Sequence terms Create a sequence with a pattern rule of "multiply by ." Sequenc

Anuta_ua [19.1K]

Answer:

Firstly, to create a sequence we need our natural numbers which will stand for our n and the pattern created will be f(n). where n = 1, 2, 3, 4, . . .

1. If we have f(n) = n + 1, then our sequence would be 2, 4, 5, 6, . . . with a pattern of adding 1 to our n.

2. If we have f(n) = n x 2, then our sequence would be 1, 4, 6, 8, . . . with a pattern of multiplying 2 by our n.

3. If we have f(n) = n + 2 when n is odd and n - 1 when even, then we have 3, 1, 5, 3, . . . as our sequence following the add subtraction pattern.

4. if we have f(n) = n x 2 when n is odd and n/1 when n is even, then we have 2, 4, 10, 6, . . .

Circle

Doss [256]

Siras ! Don't try to picture this all in your head !
You'll wear out your brain.
You MUST sketch it on a piece of paper.
Draw an x-axis and a y-axis, then draw the two circles.

I'm drawing myself a picture right now, and I'm
supposed to be some kind of a genius.

a). In order to move Circle-Q so that both centers are
at the same point, you need to move the center of Q
4 units down and 2 units to the right.
      When you do that, you'll have the little circle inside the
big circle, with their centers both at the same place.

b). The radius of Q is 2.
   The radius of P is 20.
   What do you have to multiply 2 by, in order to get 20 ?
   THAT's the scale factor to dilate Q so that it has the same
radius as P.
   When you do that, suddenly it'll look like you only have one circle
on the paper ... they'll both have the same radius and their centers are
at the same place, so you can't tell them apart.

c). All circles are similar !

I went online (you could easily go there too). I searched the question
"Are circles similar ?" and a lot of interesting stuff came up. (you could
do that too). I saw a lot of ways to prove that all circles are similar.
The best one says:

   Two figures are "similar" if you can make one of them
   exactly fit on top of the other one (make them congruent)
   with translations and dilations.

You just did that with P and Q !

-- Translation is moving them around.
   You moved Q and put the centers of both circles at the same place.

-- Dilation is blowing it up or blowing it down, so its size changes
but its shape doesn't change.
   You blew Q up so that it had the same radius as P.
   Then the two circles exactly fit over/under each other.

So the two circles are similar.
