Answer: The length of the rectangular prism is 2 inches long

Step-by-step explanation:

The volume of a rectangular prims is its height multiplied by its width multiplied by its length

h×w×l=70

We can sub in the known values of width and height and simplify

5×7×l=70

35l=70

Finally, divide both sides by 35 to isolate l

\frac{35l}{35} =\frac{70}{35} \\l=2

Assume standard deviation of all invoices is $200. Sample 100 invoices. What is the standard deviation of xbar
posledela

Answer:

<h3>20</h3>

Step-by-step explanation:

Standard deviation of the mean is expressed as:

SM = s/√n

s is the standard deviation of all invoices

n is the sample size of the invoiced

Given

s = $200

n = 100

Required

Standard deviation of the mean

Substitute the given parameters into the given equation

SM = 200/√100

SM = 200/10

SM = 20

Hence the standard deviation of xbar is 20

<h3><u>Answer</u> :</h3>

See the attachment for better understanding.

<u>G</u><u>i</u><u>v</u><u>e</u><u>n</u><u> </u>: Length of string (AC) = 300ft

<u>T</u><u>o</u><u> </u><u>F</u><u>i</u><u>n</u><u>d</u><u> </u>: Height of the kite from ground (AB)

:\implies\sf\:sin60^{\circ}=\dfrac{AB}{AC}

:\implies\sf\:\dfrac{\sqrt{3}}{2}=\dfrac{H}{300}

:\implies\sf\:H=\dfrac{300\sqrt{3}}{2}

:\implies\sf\:H=150\sqrt{3}

:\implies\:\boxed{\bf{\red{H\approx 260\:feet}}}

Hope it helps !

Simplify each expression.<br> (-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃
babymother [125]

The result of simplifying each number (-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃  using the exponent rules is -3

To solve this exercise we have to resolve algebraic operations following the exponent rules.

(-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃

Using the product rule that indicates that: the exponent result will be the addition of these exponents, we have:

(-3)¹/₃⁺ ¹/₃ ⁺ ¹/₃

(-3)³/₃

(-3)¹

-3

<h3>What is an exponent?</h3>

In mathematics an exponent is the number of time that a number, called (base) is multiplied by itself. It is also called, power or index.

Example: 3² = 3*3 = 9
