Look at the angles and the little tallies to match up the triangle. Or use the given: triangle DEF is similar to triangle KJI. If it’s like that in a given you know the order is equal. (D and K are similar, E and J, and F and I)
So if line FD is the 3rd and 1st letters of the first triangle, then it has to be equal to the 3rd and 1st letter of the 2nd triangle.
IK

Another way to do this is that when you find FD on the triangle you can set that the line has 3 tally marks. Then look at the other triangle and find a line in which there are 3 tally marks.
The order in which you put the letters does not matter. IK and KI should both be considered correct
Hope this helped

Miles has a square garden in his backyard. He decides to decrease the size of the garden by 1 foot on each side in order to make
trapecia [35]

Let

x-------> the length side of the original square garden

Step 1

<u>Find the value of x</u>

we know that

(x-1)^{2}=25

taking square root both sides

(x-1)=(+/-)\sqrt{25}

(x-1)=(+/-)5

x1=1+5=6\ ft

x2=1-5=-4\ ft

the solution is

x=6\ ft

therefore

<u>the answer Part a) is</u>

The original length side of the square garden is 6\ ft

Step 2

<u>Find the area of the original square garden</u>

we know that

the area of the original square garden is equal to

A=x^{2}

substitute the value of x in the formula

A=6^{2}=36\ ft^{2}

therefore

<u>the answer part b) is</u>

the area of the original square garden is 36\ ft^{2}

algol [13]

Answer:

Rotation because it is the right answer due to dialations changing size and reflections and translations would not change the way the shape is oriented.

A study of the use of social media asked a sample of 488 American adults under the age of 40 and a sample of 421 American adults
mr_godi [17]

Answer:

The correct option is (c).

Step-by-step explanation:

The assumptions of a two-sample <em>t</em>-test are:

  • Independent samples
  • Normality
  • Equal variances

It is provided that the sample of selected for American adults under the age of 40 is of size, <em>n</em>₁ = 488 and the sample of selected for American adults aged 40 or over is of size, <em>n</em>₂ = 421.

As the sample size is quite large the according to the Central limit theorem the sampling distribution of the sample mean would follow a Normal distribution.

And even if the sample was selected by dialing of various telephone numbers, the sample is not biased since the size of the sample is too large.

So, the sample can be considered as a simple random sample.

Thus, the conditions for two-sample t inference are satisfied.

The correct option is (c).
