Answer:
53 52 72 61 68 58 47 47 (arrange it)
47 47 52 53 58 61 68 71 (done!)
Mode: 47 (appear twice)
Median: (53+58)/2 = 55.5
Mean = 47+47+52+53+58+61+68+71/ 8
=457/8
=57.12
Given exponential expression : 
.
<em>According to exponents of exponent rule, we need to distribute whole exponent over exponents of inside terms of parenthesis.</em>
We are given whole exponent 2 there.
We can apply exponents of exponent rule.
Therefore,
Therefore, 
<h3>Correct option is second option
</h3>
<span>(x - y + 1) - (x + y - 1)
x - y + 1 - x - y + 1
= (x - x) + (y - y) + (1 + 1)
= -2y + 2
In short, Your Answer would be: -2y + 2
Hope this helps!</span>
Answer:
hypotenuse = 17.46
Step-by-step explanation:
The Pythagorean Theorem is a^2+b^2=c^2.
Since we are finding the hypotenuse, we must plug in 16 and 7 since they represent the lengths of both side.
16^2+7^2=c^2
256+49=c^2
305=c^2
which means we have to find the square root of c^2 AND 305, round it to the nearest hundredth, which means that;
c=17.46
