Answer:

x = 6

Step-by-step explanation:

Vertical angels are always equal, there fore angle A = angle B.

If angle A = angle B, and

angle A = 3x - 9 and angle B = x + 3, then

3x - 9 = x + 3

Now you can solve this like a regular inequality

Start by subtracting x by it's self then 3x to get both variables on one side.

2x - 9 = 3

Now you can add 9 to it's self and to 3 on the other side.

2x = 12

Finally, divide 2 by it's self and 12.

x = 6

An operations analyst counted the number of arrivals per minute at an ATM in each of 30 randomly chosen minutes. The results wer
liraira [26]

Step-by-step explanation:

since Poisson distribution parameter is not given so we have to estimate it from the sample data. The average number of of arrivals per minute at an ATM is

\hat{\lambda}=\bar{x}=\frac{\sum x}{n}=\frac{30}{30}=1

So probabaility for \mathrm{X}=1 is

P(X=1)=\frac{e^{-\lambda} \lambda^{x}}{x !}=\frac{e^{-1} \cdot 1^{1}}{1 !}=0.3679

So expected frequency for X=1 is 0.3679^{*} 30=11.037 (or \left.11.04\right) .

Find the distance between each pair of points. Round your answer to the nearest tenth, if necessary. Hint: Use the Pythagorean T
Paul [167]

The distance between two points on the plane is given by the formula below

\begin{gathered} A=(x_1,y_1),B=(x_2,y_2) \\ \Rightarrow d(A,B)=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2} \end{gathered}

Therefore, in our case,

A=(-1,-3),B=(5,2)

Thus,

\begin{gathered} \Rightarrow d(A,B)=\sqrt[]{(-1-5)^2+(-3-2)^2}=\sqrt[]{6^2+5^2}=\sqrt[]{36+25}=\sqrt[]{61} \\ \Rightarrow d(A,B)=\sqrt[]{61} \end{gathered}

Therefore, the answer is sqrt(61)

In general,

-(-n)=n

Remember that

-n=(-1)\cdot n

Therefore,

\begin{gathered} a-(-n)=a+(-1)(-n)=a+(-1)(-1\cdot n)=a+(-1)^2\cdot n=a+1\cdot n=a+n \\ \Rightarrow a-(-n)=a+n \end{gathered}

One-half the cube of m subtracted by 4 *
Anettt [7]

Answer:

\frac{m^3}{2}  - 4

Step-by-step explanation:

Required

Determine an expression for the given statement

The expression can be rewritten as:

one-half    *     the cube of m       subtracted by      4

Convert each statement to mathematical expressions:

One half = \frac{1}{2}

The cube of m = m^3

one-half    *     the cube of m = \frac{1}{2} * m^3

At this stage, we have:

\frac{1}{2} * m^3 subtracted by 4

This gives:

\frac{1}{2} * m^3 - 4

\frac{m^3}{2}  - 4

Hence, The corresponding expression is \frac{m^3}{2}  - 4
