Answer:
Step-by-step explanation:
1) Δ ADE ~ Δ ABC, then
⇒ 
When you rotate a figure, its shape stays the same, only its orientation changes. So, this would also be a rectangle, this time with width 17 and length 15. The area would be the same as before: length * width = 17 * 15 = 255.
Answer:
<u>The correct answer is z = 1.2</u>
Step-by-step explanation:
μ or average income = US$ 3,000
σ or standard deviation = US$ 250
Income in a given month = US$ 3,300
For calculating the z score, we use the following formula:
z = (x – μ) / σ
z = (3,300 – 3,000 / 250)
z = 300/250
z = 6/5 = 1.2
Interpreting z
A Z score tells us how many units of standard deviation (1.2 in this case)from the average a given score is, that is, we do not count in quantity of points, but in quantities of standard deviations. To use the Z score we require the distribution to be normal and to know the average and standard deviation of the scores.
The distance between the two points is 
Explanation:
Given that the two points are 
and 
We need to determine the distance between the two points in simplest radical form.
The distance between the two points can be determined using the distance formula,
Let us substitute the coordinates and in the above formula, we get,
Simplifying the terms, we get,
Squaring the terms, we get,
Adding, we get,
Simplifying, we have,
Thus, the distance between the two points in simplest radical form is
Hi.
I believe the formula for R when you have the voltage and current is:
V/I = R
Plugging in the numbers:
220/4 = 55
The answer is the second option, 55.
