Given: f(x) = x - 7 and h(x) = 2x + 3<br><br> Write the rule for h(f(x)).
OLga [1]
So basically you just want to replace all the x's in the h(x) equation with the f(x) equation. 

h(x-7) = 2(x-7) + 3 
h(x) = 2x -14 + 3 
h(x) = 2x - 11

What is the area of the triangle in this coordinate
EastWind [94]

Answer:

<h2>A = 16.5 square units</h2>

Step-by-step explanation:

It's the right triangle.

The formula of an area of a right triangle:

A=\dfrac{(leg)(leg)}{2}

Look at the picture.

We have

leg=3,\ leg=11

Substitute:

A=\dfrac{(3)(11)}{2}=\dfrac{33}{2}=16.5

Sample annual salaries​ (in thousands of​ dollars) for employees at a company are listed. ​(a) Find the sample mean and sample s
Helen [10]

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

The value is attached in the image file please find it.

In point a:

First, we calculate the find the mean,

Formula:

\to Mean (\bar{x}) = \frac{( \sum x)}{n}

                   =\frac{540}{13}\\\\ = 41.54

To calculate the standard deviation, subtract the mean value from all observations then square its value:

SD = \sqrt{\frac{\sum(x-\bar{x})^2}{n-1}} \\   = \sqrt{ \frac{339.2308}{13-1}}

                             = \sqrt{ \frac{339.2308}{12}}\\\\= \sqrt{28.269}\\\\=5.31

please find attached file

In point b:

New x_i = 1 x_i + 0.05 x_i = 1.05 x_i

Calculate new mean:

\to \bar{x} = \frac{\sum x}{n} \\

       =\frac{567}{13} \\\\= 43.62

calculating the standard deviation:

SD = \sqrt{\frac{\sum(x-\bar{x})^2}{n-1}} \\   = \sqrt{ \frac{374.0022}{13-1}}

                             = \sqrt{ \frac{374.0022}{12}}\\\\= \sqrt{31.16}\\\\=5.58

please find attached file

In point C:

Calculate new mean:

\to \bar{x} = \frac{\sum x}{n} \\

       =\frac{47.25}{13} \\\\= 3.46

calculating the standard deviation:

SD = \sqrt{\frac{\sum(x-\bar{x})^2}{n-1}} \\   = \sqrt{ \frac{2.5975}{13-1}}

                             = \sqrt{ \frac{2.5975}{12}}\\\\= \sqrt{0.216}\\\\=0.46

please find attached file

In point d:

for b,

New \bar{x}= 1.05 \bar{x}= 1.05(41.54) =43.62

News= 1.05s= 1.05(5.31)=5.57

for c,

New\bar{x}= \frac{ \bar{x}}{12}= \frac{41.54}{12} = 3.46

New s = \frac{s}{ 12} = \frac{5.31}{12}= 0.44

Naddika [18.5K]

Answer:

3/10

Step-by-step explanation:

Since you are only choosing a marble in the bag and there are three green marbles to choose from out of the 10 marbles combined, you will have a 30% chance of getting a green marble in which you have 3/10 as your probability.

Does anyone has Algebra ll and if so can you please help me with this problem 5i/-2-6i And also I can't pay you but I hope God c
asambeis [7]

Answer:

s = \frac{5i}{-2-6i} = -\frac{30}{40}-\frac{10}{40}i

Step-by-step explanation:

We have the following complex number s = \frac{5i}{-2-6i}, we proceed to simplify the expression as follows:

1) \frac{5i}{-2-6i} Given.

2) (5i)\cdot (-2-6i)^{-1} Definition of division.

3) [(5i)\cdot (-2-6i)^{-1}]\cdot [(-2+6i)\cdot (-2+6i)^{-1}] Modulative and associative properties/Existence of the additive inverser

4) [(5i)\cdot (-2+6i)]\cdot [(-2-6i)^{-1}\cdot (-2+6i)^{-1}] Commutative and associative properties.

5) [(5i)\cdot (-2+6i)]\cdot [(-2-6i)\cdot (-2+6i)]^{-1} a^{c}\cdot b^{c} = (a\cdot b)^{c}

6) [(5i)\cdot (-2+6i)]\cdot [4+36]^{-1}    (a+b)\cdot (a-b) = a^{2}-b^{2}/Definition of complex number/  a\cdot (-b) = -a\cdot b

7) [(5i)\cdot (-2)+(5i)\cdot (6i)]\cdot 40^{-1} Definition of sum.

8) (-10\cdot i+30\cdot i^{2})\cdot 40^{-1}    a\cdot (-b) = -a\cdot b/Associative and commutative properties.

9) (-30-10i)\cdot 40^{-1} Commutative properties/Definition of complex number/ a\cdot (-b) = -a\cdot b

10) -30\cdot 40^{-1}-(10i)\cdot 40^{-1} Distributive property.

11) -\frac{30}{40}-\frac{10}{40}i Definition of division/Result.

s = \frac{5i}{-2-6i} = -\frac{30}{40}-\frac{10}{40}i
