Answer:

x ≤ 3

Step-by-step explanation:

In the graph given, values of variable x is represented.

From the plot, we note that a small circle is at point 3 on the numberline. This small "o" is shaded, which indicates that the values of x includes 3.

The arrow which starts at 3 on the numberline, points towards our left. This means that the values of x are less than or equal to 3. No value of x is greater than 3.

Therefore, the following inequality can be written for the graph:

x ≤ 3

Answer:

-1

Step-by-step explanation:

First find the inverse function.  Rewrite the given function as

y = 5(x + 4) - 6  =  5x + 20 - 6  =  5x + 14

Second, interchange x and y:

x = 5y + 14

Third, solve this result for y:

5y = 14 - x, or y = (1/5)(14 - x)

This last result is the inverse function of the given f(x).

The value of this inverse at x = 19 is (1/5)(14 - 19) = (1/5)(-5) = -1

Answer:

15 years.

Step-by-step explanation:

We have the equation:

20000 = 10000(1 + 0.048)^t     where t is the number of years.

1.048 t = 20000/10000 = 2

Taking logs:

t ln 1.048 = ln 2

t = ln 2 / ln 1.048

t = 14.78

Answer:

la distancia del punto de observación A al incendio = 5.5 millas

la distancia del punto de observación B al incendio = 3.8 millas

Step-by-step explanation:

La expresión esquemática de la pregunta se puede ver en la imagen adjunta a continuación :

Del siguiente diagrama;

Usando la sine regla:

[tex]\dfrac{sin \ F}{f} = \dfrac{sin \ A }{a}[/tex]

[tex]\dfrac{sIn \ 79}{6} = \dfrac{sin \ 63}{a}[/tex]

a sin 79 = 6 sin 63

[tex]a =\dfrac{6 \times sin \ 63}{sin \ 79}[/tex]

[tex]a =\dfrac{6 \times 0.8910}{0.9816}[/tex]

a = 5.446 millas

la distancia del punto de observación A al incendio = 5.5 millas (a la décima más cercana)

[tex]\dfrac{sin \ F}{f} = \dfrac{sin \ B}{b}[/tex]

[tex]\dfrac{sin \ 79}{6} = \dfrac{sin \ 38}{b}[/tex]

b sin 79 = 6 sin 38

[tex]b = \dfrac{6 \times sin \ 38}{sin \ 79}[/tex]

[tex]b = \dfrac{6 \times0.6157 }{0.9816}[/tex]

b = 3.7635 millas

la distancia del punto de observación B al incendio = 3.8 millas (a la décima más cercana)

The null hypothesis is  [tex]H_o: \mu_1 = \mu_2[/tex]

The  alternative hypothesis is  [tex]H_1 : \mu_1 \ne \mu_2[/tex]

The test statistics is  [tex]t = -1.667[/tex]

Step-by-step explanation:

From the question we are told that

  The first sample size is  [tex]n_1 = 12[/tex]

   The  first sample  mean is  [tex]\= x_1 = 79.8[/tex]

    The first standard deviation is  [tex]\sigma _1 = 8.8[/tex]

   The second sample  size is  [tex]n_2 = 17[/tex]

    The  second  sample  mean is  [tex]\= x_2 = 85.2[/tex]

    The second  standard deviation is  [tex]\sigma _2 = 8.3[/tex]

The null hypothesis is  [tex]H_o: \mu_1 = \mu_2[/tex]

The  alternative hypothesis is  [tex]H_1 : \mu_1 \ne \mu_2[/tex]

Generally the test statistics is  mathematically represented as  

                 [tex]t = \frac{\= x_ 1 - \= x_2 }{ \sqrt{ \frac{\sigma_1^2 }{n_1 } +\frac{\sigma_2^2 }{n_2} } }[/tex]

   =>          [tex]t = \frac{ 79.8 - 85.2 }{ \sqrt{ \frac{8.8^2 }{12} +\frac{ 8.3^2 }{17} } }[/tex]

=>                [tex]t = -1.667[/tex]

the answer is -67 because you use the given function to set up and simplify  f(7).

Answer:

10 and 11

Step-by-step explanation:

Let the first integer be x.

Then the next one, since it's consecutive, must be (x+1).

The two equals 21. Thus:

[tex](x)+(x+1)=21[/tex]

Combine like terms:

[tex]2x+1=21[/tex]

Subtract 1 from both sides:

[tex]2x=20[/tex]

Divide both sides by 2:

[tex]x=10[/tex]

So, the first integer is 10.

And the second integer is 10+1=11.

Answer:

10 , 11

Step-by-step explanation:

The sum of two consecutive integers is 21.

Let the least of the integer be signified by the variable x.

Consecutive means "directly after", which means the other integer would be: x + 1

Set the equation:

(x) + (x + 1) = 21

Simplify. Combine like terms:

x + x + 1 = 21

(x + x) + 1 = 21

2x + 1 = 21

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 1 from both sides:

2x + 1 (-1) = 21 (-1)

2x = 21 - 1

2x = 20

Next, divide 2 from both sides:

(2x)/2 = (20)/2

x = 20/2

x = 10

Plug in 10 for x in the equation:

(x) + (x + 1) = 21

10 + (10 + 1) = 21

10 + 11 = 21

21 = 21 (True)

The two numbers are 10, 11.

[tex]Sum=4*[\frac{n^2-1}{n^2}][/tex]

For n=10:

Sum=3.96

For n=100:

Sum=3.9996

For n=1000:

Sum=3.999996

For n= 10000:

Sum=3.99999996

Step-by-step explanation:

Formula:

[tex]\sum_{k=1}^n \frac{12k(k-1)}{n^3}[/tex]

Rearranging the above formula:

[tex]\sum_{k=1}^n \frac{12}{n^3}*k(k-1)\\\sum_{k=1}^n \frac{12}{n^3}*(k^2-k)[/tex]            Eq (1)

According to summation formula:

[tex]\sum_{k=1}^n\ k= \frac{n(n+1)}{2}\\ \sum_{k=1}^n\ k^2= \frac{n(n+1)(2n+1)}{6}\\[/tex]

Putt these in Eq (1), and we will get:

[tex]=\frac{12}{n^3}[\frac{n(n+1)(2n+1)}{6}-\frac{n(n+1)}{2}]\\Taking\ n\ as\ common\\=n*\frac{12}{n^3}[\frac{(n+1)(2n+1)}{6}-\frac{(n+1)}{2}] \\=\frac{12}{n^2}*[\frac{(n+1)(2n+1)}{6}]-\frac{12}{n^2}*[\frac{(n+1)}{2}] \\=\frac{2*(n+1)(2n+1)}{n^2}-\frac{6(n+1)}{n^2}\\[/tex]

Taking [tex]2(n+1)[/tex] as common:

[tex]=2(n+1)*\frac{2n+1-3}{n^2} \\=(2n+2)*\frac{2n-2}{n^2}\\=\frac{4n^2-4}{n^2}[/tex]

After more simplifying,

[tex]Sum=4*[\frac{n^2-1}{n^2}][/tex]

Now ,for n=10:

For n=10000:

[tex]Sum=4[\frac{(10000^{2})-1}{10000^{2}}]\\Sum=3.99999996[/tex]

Answer:

Step-by-step explanation:

Since angles R and S are supplementary angles it means that the sum of their angles add up to 180°

To find R we must first find x

To find x , add angles R and S and equate them to 180

That's

R + S = 180

80 - x + 3x - 30 = 180

2x + 50 = 180

2x = 180 - 50

2x = 130

Divide both sides by 2

x = 65°

From the question

R = 80 - x

But x = 65°

Substitute the value of x into the expression

That's

R = 80 - 65

We have the final answer as

Answer:

(-3,0) and (1,0)

Step-by-step explanation:

The x-intercepts of the function that is graphed above are the points where the line of the graph intercepts or crosses the y-axis. At that point, y is always 0.

Thus, the line of the graph intercepts the x-axis at x = -3, when y = 0 (-3, 0), and also at x = 1, when y = 0 (1, 0).

Therefore, the x-intercepts of the graphed function are (-3,0) and (1,0).

Answer:

[tex]x = -\frac{5}{7}, 2[/tex]

Step-by-step explanation:

To solve this equation, we need to simplify it down first. To do this, we must apply the distributive property to each term.

[tex]7x(x-2) + 5(x-3) = -5\\\\(7x^2 - 14x) + (5x - 15) = -5[/tex]

Now we can combine like terms.

[tex]7x^2 - 9x - 15 = -5[/tex]

Add 5 to both sides:

[tex]7x^2 -9x - 10 = 0[/tex]

We can see that this is a quadratic equation, in the form [tex]ax^2 + bx + c[/tex]. To solve for x, we must use the Quadratic Formula, which is [tex]\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex], where a is 7, b is -9, and c is -10.

Substitute inside the equation:

[tex]\frac{-(-9)\pm\sqrt{-9^2-4\cdot7\cdot-10}}{2\cdot7}\\\\\frac{9\pm\sqrt{81+280}}{14}\\\\\frac{9\pm19}{14}\\\\(9+ 19)\div14 = 2\\\\(9 - 19)\div14 = -\frac{5}{7}[/tex]

Answer:

The probability of rolling a 2 then 4 is 3%

Step-by-step explanation:

Given

A die rolled twice

Required

Probability of rolling a 2 then 4; i.e. P(2 n 4)

First, we need to list out the sample space

[tex]S = \{1,2,3,4,5,6\}[/tex]

[tex]n(S) = 6[/tex]

Next, is to calculate P(2)

[tex]P(2) = \frac{n(2)}{n(S)}[/tex]

[tex]P(2) = \frac{1}{6}[/tex]

Next, is to calculate P(4)

[tex]P(4) = \frac{n(4)}{n(S)}[/tex]

[tex]P(4) = \frac{1}{6}[/tex]

Next,is to calculate the required probability using the following formula

[tex]P(2\ n\ 4) = P(2) * P(4)[/tex]

[tex]P(2\ n\ 4) = \frac{1}{6} * \frac{1}{6}[/tex]

[tex]P(2\ n\ 4) = \frac{1}{36}[/tex]

[tex]P(2\ n\ 4) = 0.02777777777[/tex]

Convert to Percentage

[tex]P(2\ n\ 4) = 2.777777777\%[/tex]

Approximate

[tex]P(2\ n\ 4) = 3\%[/tex]
