The vertices of triangle PQR are P(10,-6), Q(6,2), & R(4,-1). Describe a translation that places the image of the triangle e

Gnoma [55]

Answer:

Translate 7 units up and then translate 11 units to the left.

Step-by-step explanation:

We have the triangle PQR having co-ordinates (10,6), (6,2) and (4,-1).

It is required to translate ΔPQR so that the resulting image is completely inside the 2nd quadrant.

So, for that we will apply the following sequence of translations:

1. Translate 7 units up.

This will give us the figure in the 1st quadrant having co-ordinates (10,1), (6,9) and (4,6).

2. Translate 11 units to the left

We will get the final triangle P'Q'R' with the co-ordinates P'(-1,1), Q'(-5,9) and R'(-7,6) as shown below.

jeyben [28]

Answer:

The sample size must be atleast 3600

Step-by-step explanation:

We are given the following in the question:

The scores of individual students on the American College Testing (ACT) Program is a bell shaped distribution that is a normal distribution.

Population standard deviation = 6.0

We want that the sample standard deviation should not be more than 0.1.

Thus, the standard error should not be more than 0.1.

Standard error =

$=\dfrac{\sigma}{\sqrt{n}}$

Putting values, we get,

$\dfrac{\sigma}{\sqrt{n}}\leq 0.1\\\\ \dfrac{6}{\sqrt{n}} \leq 0.1\\\\ \sqrt{n}\geq 60\\n\geq 3600$

Thus, the sample size must be atleast 3600

Jorell is incorrect, because converting 18 out of 40 shots into a fraction is 18/40. In order to determine the percentage of shots which Jorell made, you can divide the two numbers. 18 divided by 40 is equal to .45. To convert .45 into a percentage, move the decimal over twice. Therefore, Jorell made 45% of the shots and not 40%.
