Answer:

[tex]\displaystyle \frac{3^5}{3^{-6}}=3^{11}[/tex]

Step-by-step explanation:

Properties of Exponents

They can be used to simplify expressions of the form

[tex]b^x\cdot b^y=b^{x+y}[/tex]

[tex]\displaystyle \frac{b^x}{b^y}=b^{x-y}[/tex]

The last property will be used to simplify:

[tex]\displaystyle \frac{3^5}{3^{-6}}=3^{5-(-6)}=3^{5+6}=3^{11}[/tex]

[tex]\mathbf{\displaystyle \frac{3^5}{3^{-6}}=3^{11}}[/tex]

Answer:

P(X>5) = 0.857

Step-by-step explanation:

Let X [tex]\sim[/tex] uniform(3.17)

[tex]f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17[/tex]

The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:

[tex]P(X > 5) = \int ^{17}_{5} f(x) \ dx[/tex]

[tex]P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx[/tex]

[tex]P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}[/tex]

[tex]P(X > 5) =\dfrac{1}{14} [17-5][/tex]

[tex]P(X > 5) =\dfrac{12}{14}[/tex]

P(X>5) = 0.857

Answer:

509

Step-by-step explanation:

formula

L = a + (n - 1)*d

Givens

n = 57

a = 5

d = 9

Solution

t = 5 + (57 - 1)*9

t = 5 + 56*9

t = 5 + 504

t = 509

t = 556

Step-by-step explanation:

Answer:

y=1/5(x+37)

Step-by-step explanation:

y=1/5x+4/5

Plug in the (3,8)

8=1/5(3)+b

8=3/5+b

7 2/5=b

y=1/5(x+37)

The equation of the line is y = 1/5(x + 37)

Since our new line is parallel to the line y = 1/5(x + 4), and 1/5 is the gradient of the line y = 1/5(x + 4), the gradient of the new line is 1/5.

Using the equation of a line in slope-point form,  [tex]\frac{y - y_{1} }{x - x_{1} } = m[/tex] where (x₁, y₁) = (3, 8) and m = 1/5

Substituting the values of the variables into the equation, we have

[tex]\frac{y - y_{1} }{x - x_{1} } = m[/tex]

[tex]\frac{y - 8 }{x - 3 } = \frac{1}{5}[/tex]

Cross-multiplying. we have

5(y - 8) = x - 3

Expanding the bracket, we have

5y - 40 = x - 3

5y = x - 3 + 40

5y = x + 37

y = 1/5(x + 37)

So, the equation of the line is y = 1/5(x + 37)

Answer:

The value is  [tex]P(X > 500 ) = 0.011942[/tex]

Step-by-step explanation:

From the question we are told that

       The mean is  [tex]\mu = 430[/tex]

       The standard deviation is  [tex]\sigma = 120[/tex]

       The sample size is  n  =  15

Generally  the probability that the sample mean is above 500

Gnerally the standard error of mean is mathematically represented as

             [tex]s = \frac{\sigma }{ \sqrt{n} }[/tex]

=>          [tex]s = \frac{ 120 }{ \sqrt{15} }[/tex]

=>           [tex]s = 30.984[/tex]

Generally  the probability that the sample mean is above 500

     [tex]P(X > 500 ) = P( \frac{X - \mu }{\sigma_x} > \frac{500 - 430 }{ 30.984 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

       [tex]P(X > 500 ) = P( Z > 2.259 )[/tex]

=>     [tex]P(X > 500 ) = P( Z > 2.259 )[/tex]

From the z table  the area under the normal curve to the right  corresponding to  2.259  is

          [tex]P( Z > 2.259 ) = 0.011942[/tex]

=>       [tex]P(X > 500 ) = 0.011942[/tex]
