Answer:

\huge\boxed{\bf\:\frac{4}{3} }

Step-by-step explanation:

If, x^{2} = 64, then,

x^{2} = 64\\x = \sqrt{64}\\x = (+/-)8

Now, remember that any number when folllowed by exponent 0 will always have its value as 1.

Then,

\frac{1}{3} + x^{0} \\ =\frac{1}{3} + (+/-8)^{0} \\= \frac{1}{3} + 1\\=\frac{1}{3} +\frac{3}{3} \:\:\:\: (LCM = 3)\\ \boxed{\bf\:\frac{4}{3} }

Answer:

<u>4/3 or 1 1/3</u>

Step-by-step explanation:

<u>Finding x</u>

  • x² = 64
  • x = ±8

<u>Substitute in the equation</u>

  • 1/3 + (±8)⁰
  • 1/3 + 1
  • <u>4/3 or 1 1/3</u>

what are the mean variacne and standard deviatioon of the values? round to the nerates tenth. 11,11,3,1,11
alexdok [17]

Answer:

Mean = 8

Variance = 22

Standard deviation = 4.6904

Step-by-step explanation:

To find out Mean the formula is : total sum of data set / number of values

(11 + 11 + 3 + 1 + 11 + 11) / 6 = 48 / 6 = 8

Mean = 8

Now for variance we will form a table

x                  11     11     3      1      11      11

(x - Mean)    3     3    -5     -7      3      3  

(x - Mean)²   9     9    25    49    9      9

Now we the formula of variance =

Variance = (9+9+25+49+9+9)/(6-1) = 110/5 = 22

Variance = 22

Now we know Standard deviation = √(variance)

Therefore standard deviation = √22 = 4.6904

Hope this helps!<3

Evaluate the following expression when x = -5 and y = 25.
kykrilka [37]

Answer:

<u>The correct answer is A. 3,120.</u>

Step-by-step explanation:

Let's solve the expression for x = -5 and y = 25, this way:

(5|x| - y³)/x

Replacing x and y, we have:

(5 * 5 - 25³)/-5 (Absolute value of -5 is 5 in the numerator but we keep it without changes in the denominator)

(25 - 15,625)/-5

-15,600/-5

3,120

<u>The correct answer is A. 3,120.</u>
