Calculate the mean of this data set.

Answer:

Option B is correct

Step-by-step explanation:

We have function f(x)=(x+3)2

The domain of the function is the set of values for which the function is defined and real.

In our case if x belong to all real numbers the function will be real and defined as given in Option B as function has no undefined points.

All other options are subset of real numbers.

So, option B is correct.

ANSWER

[tex]x = 5 {y}^{2} + 10[/tex]

EXPLANATION

The given equation is :

[tex]y = 5 {x}^{2} + 10[/tex]

To find the inverse of this function, we interchange x and y to obtain:

[tex]x= 5 {y}^{2} + 10[/tex]

We simplify this function to solve for y.

Therefore the equation that needs to be simplified to find the inverse of the given function is

[tex]x = 5 {y}^{2} + 10[/tex]

The correct choice is is the first option.

Answer: x = 5y2 + 10

Step-by-step explanation: A is the correct answer on the Quiz!

For this case we have a function of the form [tex]y = f (x)[/tex], where:

[tex]f (x) = \frac {5 + x} {6 + 3x}[/tex]

We must evaluate the function at[tex]x = a-1[/tex]

So:

[tex]g (a-1) = \frac {5+ (a-1)} {6 + 3 (a-1)}\\g (a-1) = \frac {5 + a-1} {6 + 3a-3}\\g (a-1) = \frac {4 + a} {3 + 3a}[/tex]

Thus, the value of the function is:

[tex]\frac {4 + a} {3 + 3a}[/tex]

Answer:

[tex]g (a-1) = \frac {4 + a} {3 + 3a}[/tex]

Step-by-step explanation:

bc is along a straight line with section 4 straight lines are 180° if bc is 30° then 180°-30°=150°

Answer:

The measure of ∠4 is 150°

Step-by-step explanation:

Given the figure in which BD is the diameter of circle and

m∠1=100°

m(arc BC)=∠3=30°

we have to find the measure of ∠4.

As BD is a straight line as BD is diameter therefore

∠4 and ∠3 forms a linear pair

⇒ ∠4 and ∠3 are supplementary i.e these angles adds up to 180°

∠4 + ∠3 = 180°

∠4+30°=180°

∠4=180°-30°=150°

Hence, the measure of ∠4 is 150°

Answer:

The number is 6

Step-by-step explanation:

We let the number be x. If we subtract -2 from x we obtain the following result;

x - (-2)

This can be simplified to yield the following result;

x - (-2) = x + 2

we use the rule that negative multiplied by negative yields a positive sign.

We are further informed that the result of the above operation is 8, therefore;

x + 2 = 8

Solving for x yields;

x = 8 -2

x = 6

the number that we are looking for is 6.

The question asks us to find the number that results in 8 when -2 is subtracted from it. To solve this, we can set up an equation. Let x be the number we are looking for:

x - (-2) = 8

We know that in subtraction, we change the sign of the subtracted number and then follow the addition rules. This means our equation becomes:

x + 2 = 8

Now we subtract 2 from both sides to find the value of x:

x = 8 - 2

x = 6

Thus, the number that we are looking for is 6.

Use the slope formula

Answer:

9.43398

Step-by-step explanation:

The formula is square root of (x2-x1)^2 + (y2-y1)^2.  

So if you plug in the equation, it is 9.43398.

Answer: You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.

Step-by-step explanation:

The equation of the line must be 2x - 1

The equation of the line that represents an equation of a line with a slope of 2 and a point on the line of (1, 2) can be written in the form:

[tex]y-y_0=m(x-x_0)[/tex]

m is the slope of the line

(x0, y0) is the point on the line

Substitute the given parameters into the formula to have:

[tex]y-2=2(x-1)\\y - 1= 2x - 2\\y = 2x -2+1\\y = 2x-1[/tex]

Hence the equation of the line must be y= 2x - 1

Answer:

(f * g)(x) = 4x^3 - x^2

[tex]4x^{3}-x^{2}[/tex]

Step-by-step explanation:

We have been given the following functions;

f(x) = 4x - 1

g(x) = x^2

We are required to determine;

(f * g)(x)

This simply means we shall be finding the product of the two functions given;

(f * g)(x) =  f(x)*g(x)

(f * g)(x) =  x^2 * (4x - 1 )

we open the brackets by multiplying each term by x^2

(f * g)(x) = x^2(4x) + x^2(-1)

(f * g)(x) = 4x^3 - x^2

Try this option:

1.

[tex]\frac{10-4}{(-3)*(-5)+8*2}=6[/tex]

2.

[tex]\frac{8+2-4}{\frac{10}{-5}-(-3)} =6[/tex]

For this case we have that by definition, the domain of a function, is given for all the values for which the function is defined.

We have:

[tex]f (x) = \frac {x + 1} {x ^ 2-6x + 8}[/tex]

The given function is not defined when the denominator is equal to zero. That is to say:

[tex]x ^ 2-6x + 8 = 0[/tex]

To find the roots we factor, we look for two numbers that when multiplied give as a result "8" and when added as a result "-6". These numbers are:

[tex]-4-2 = -6\\-4 * -2 = 8[/tex]

Thus, the factored polynomial is:

[tex](x-4) (x-2) = 0[/tex]

That is to say:

[tex]x_ {1} = 4\\x_ {2} = 2[/tex]

Makes the denominator of the function 0.

Then the domain is given by:

All real numbers, except 2 and 4.

Given : At a high school movie night, the refreshment stand sells popcorn and soft drinks. Of the 100 students who came to the movie, 62 bout popcorn and 47 bought a drink. 38 students bought both popcorn and a drink.

To find : What is the probability that a student buys a drink?          

Solution :

Total number of students are T=100 who came to the movie.

Student who bought popcorn = 62

Student who bought drink = 47

Students who bought both popcorn and a drink = 38

We have to find the probability that a student buys a drink.

Answer:

[tex]h(-9)=-\frac{2}{33}[/tex]

Step-by-step explanation:

The given expression is [tex]h(r)=\frac{2}{3r-6}[/tex]

We want to find the value of h(-9).

We substitute r=-9 to obtain:

[tex]h(-9)=\frac{2}{3(-9)-6}[/tex]

We multiply out to obtain:

[tex]h(-9)=\frac{2}{-27-6}[/tex]

We simplify the denominator to obtain:

[tex]h(-9)=\frac{2}{-33}[/tex]

This is the same as:

[tex]h(-9)=-\frac{2}{33}[/tex]

The value of h(-9) is 0. Function substitution is a mathematical technique that involves replacing a variable with an expression or function, simplifying calculations and solving equations by making them more manageable.

To find h(-9), you simply substitute -9 for r in the function h(r):

h(-9) = (2/3) * (-9) - 6

Now, calculate it step by step:

h(-9) = (-18/3) - 6

Since -18/3 is -6, the equation simplifies to:

h(-9) = -6 - 6

Now, add -6 and -6:

h(-9) = -12

So, the value of h(-9) is -12.

what is 66 1/2% as a decimal and fraction: 0.665 and 665/1000, 133/200

Step-by-step explanation:

These are basically 3 problems, so I won't explain two items for every one of your 13 similar questions.  Here's the explanation for every 3 cases asked in your questions... and the answers.  All you have to do is replace the numbers in the explanations for the ones in each other question asking the same thing.

To express a fraction in percentage, you simply have to put the fraction with a denominator of 100..., for example:

[tex]\frac{1}{20} * \frac{5}{5}  = \frac{5}{100}[/tex]

So, 1/20 is 5%.

[tex]\frac{1}{2} * \frac{50}{50}  = \frac{50}{100}[/tex]

And 1/2 is 50%

To express a percentage as a fraction, you take that percentage and place it over a denominator of 100 and you simplify, like this:

[tex]\frac{12.5}{100} = \frac{1}{8}[/tex]

[tex]\frac{30}{100} = \frac{3}{10}[/tex]

To convert a decimal number to a fraction, the easiest way is to express this number up to the 2nd decimal... then take that as a %.  

Examples:

0.2 you can say 0.2 = 0.20...  so it's 20 hundredths, or 20 per 100... so 20%

0.375, it's already expressed in more than hundredths, so you simply move the dot 2 spots right to get 37.5%

what is 1/20 as a decimal and a percentage: 5% (see above)

what 1/10 as a decimal and a percentage : 10% (save as above)

what 12 1/2% as a decimal and a percentage: 12.5%, it's already as a percentage, if you mean as a fraction... 1/8 (see above)

what is 0.2 as a fraction and a percentage: 1/5 and 20% (see above)

what is 25% as a decimal and fraction: 0.25 and 1/4

what is 30% decimal and fraction :  0.3 and 3/10

Answer: Sally will catch up with Jane after 50 minutes.

Step-by-step explanation:

Since we have given that

Speed of Jane of biking = 12 mph

After 10 minutes,

Speed of Sally of biking = 15 mph

Let the distance be 'x'.

According to question, our required equation becomes,

[tex]\dfrac{x}{12}-\dfrac{x}{15}=\dfrac{10}{60}\\\\\dfrac{5x-4x}{60}=\dfrac{1}{6}\\\\\dfrac{1x}{60}=\dfrac{1}{6}\\\\x=10\ miles[/tex]

Thus, total distance would be 10 miles.

So, the time taken by Sally to catch up with Jane is given by

[tex]\dfrac{10}{12}=\dfrac{5}{6}\times 60=50\ minutes[/tex]

Hence, Sally will catch up with Jane after 50 minutes.
