Answer:

Step-by-step explanation:

We are given the expression:

1/3z+10

We also are given z=135. Since z is equal to 135, we can substitute 135 in for z.

1/3(135)+10

Now, solve according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

Multiply 135 by 1/3, or divide 135 by 3.

45+10

Add 45 and 10

How do you find a nonzero rational number closed under division

vredina [299]

For rational numbers to be closed under division, then any rational number divided by another rational number would have to be a rational number. This works for every rational number except when the second number is 0. Since division by 0 is undefined, dividing any rational number by the rational number zero will not give you a rational number. In order to make the rational numbers closed under division, you can choose any rational number you want except 0.

In other words, the set of rational numbers is not closed under division. The problem occurs only with division by zero. The set of rational numbers from which zero is removed is closed under division.

Every nonzero rational number is closed under division.

512 feet because to find the area u multiply length times width and since your givin the area and width you divide the area by the width

Solve for x.

astra-53 [7]

Answer:

Option: C is correct.

$x=\ln\sqrt{\dfrac{t+1}{1-t}}$

Step-by-step explanation:

We are asked to solve for 'x' such that we are given a equation as:

$\dfrac{e^x-e^{-x}}{e^x+e^{-x}}=t$

This equation could also be written as:

$e^x-e^{-x}=t(e^x+e^{-x})\\\\e^x-e^{-x}=te^x+te^{-x}\\\\e^x-te^x=te^{-x}+e^{-x}\\\\(1-t)e^x=(t+1)e^{-x}\\\\e^{2x}=\dfrac{t+1}{1-t}$

on taking logarithmic function on both the sides we have:

$2x=\ln (\dfrac{t+1}{1-t})$

(since $\ln (e^x)=x$ )

$x=\dfrac{1}{2}\times \ln (\dfrac{t+1}{1-t})$

as we know $\dfrac{1}{2}\times \ln b = \ln (b^\frac{1}{2})$

Hence, we have: $x=\ln\sqrt{\dfrac{t+1}{1-t}}$

Hence, option C is correct.

Give reasons why teachers use measures of variability i n examination analysis

baherus [9]

Answer:

<h2>The range is the simplest measure of variability to compute. The standard deviation can be an effective tool for teachers. The standarddeviation can be useful in analyzing class room test results. A large standarddeviation might tell a teacher the class grades were spead a great distance from the mean.</h2>
