Hello.
Move <span><span>−25</span><span>-25</span></span> to the right side of the equation by subtracting <span><span>−25</span><span>-25</span></span> from both sides of the equation.<span><span><span>x2</span>=25</span><span><span>x2</span>=25
</span></span>Take the square root of both sides of the equation to eliminate the exponent on the left side.
<span><span>
</span></span>The complete solution is the result of both the positive and negative portions of the solution.
Simplify the right side of the equation.
Rewrite <span>2525</span> as <span><span>52</span><span>52</span></span>.
Pull terms out from under the radical, assuming positive real numbers.The complete solution is the result of both the positive and negative portions of the solution.

Answer:
5y^5
Step-by-step explanation:
there is no real solution. really i just simplified. if you wanted a real answer y would have to be giving. if not then this is all the question is asking. for you to simplify
Answer:
a. Grand Mean = 2.799
b. Standard Deviation = 0.01387
c. Standard Error = 0.0016
d. The range with a Z score of 3 = (2.75739, 2.84061)
Step-by-step explanation:
a. Grand mean :
Given that
Sum of 80 values = 223.91
Total observation = 80
Grand mean = 223.91/80 = 2.799
b. With the excel command "STDEV[range of cells]", we get the standard deviation as = 0.01387
c. Standard error = Standard deviation / root of n

d. The range with a Z score of 3 :
lower limit = mean - (3 * SD) = 2.799 - (0.04161) = 2.75739
upper limit = mean + (3 * SD) = 2.799 + (0.04161) = 2.84061
Answer:
8x + 1/2 or 8x + 0.5
Step-by-step explanation:
-6x + 3 3/4 + 14x - 3.25
u can either convert the fraction to a decimal or convert the decimal into a fraction, i'm going to do the latter
-6x + 3 3/4 + 14x - 3 1/4
rearrange to make it easier, don't need to do this i'm just doing this for the sake of it
-6x + 14x + 3 3/4 - 3 1/4
8x + 2/4, simplify this
8x + 1/2
The decimal way if u want:
-6x + 3 3/4 + 14x - 3.25
-6x + 3.75 + 14x - 3.25
-6x + 14x + 3.75 - 3.25
8x + 0.5
It’s A because when u do (6.4)^2 times pi equals 128.6796351 and u subtract to the total volume(1119.5cm) and equals to 8.69; u later round to nearest tenth which equals to A, 8.7cm
