The interval of times which represents the middle 68% of Ryan's finishing times in the 400 meter race, using the empirical rule, is 74.5 seconds to 75.5 seconds.

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]

Here we had  where mean of distribution of X is [tex]\mu[/tex]  and standard deviation from mean of distribution of X is [tex]\sigma[/tex].

When Ryan runs the 400 meter dash, his finishing times are normally distributed with a mean of 75 seconds and a standard deviation of 0.5 seconds.

The interval of times that represents the middle 68% of his finishing times in the 400 meter race is,

[tex]P(75 - 0.5 < X < 75 + 0.5) = 68\%\\P(74.5 < X < 75.5) = 68\%[/tex]

Thus. the interval of times which represents the middle 68% of Ryan's finishing times in the 400 meter race, using the empirical rule, is 74.5 seconds to 75.5 seconds.

The inverse of the function is f ( x )⁻¹ = x + 4

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x - 4   be equation (1)

On simplifying , we get

The inverse of the function is given by replacing x with y

So , the value of the function is

y = x - 4

x = y + 4

On interchanging , we get

f ( x )⁻¹ = x + 4

Hence , the inverse is f ( x )⁻¹ = x + 4

System of equations are equations that is more than one and have two or more unknowns. The solution to the given system of equation is expressed as (0, 2)

System of equations are equations that is more than one and have two or more unknowns.

Given the simultaneous equation

m + 4n = 8

m = n - 2

Substitute equation 2 into 1 to have:

n - 2 + 4n = 8

5n - 2  = 8

5n = 10

n = 2

Recall that m = n - 2

m = 2 - 2

m = 0

Hence the solution to the given system of equation is expressed as (0, 2)

Step-by-step explanation: Reflection across the x axis only flips the sign of the y axis

Answer:

the numbers are -5 and 3

Step-by-step explanation:

First of all, the question is asking you to find the values of x from the given inequalities.

-8x -19<21 and 3x - 4 < 5

group all liked terms, in other words, make x and its coefficient stand alone.

-8x < 21 + 19 and 3x < 5 + 4

-19 became +19 because it crossed the sign <, also -4 became +4 because it crossed the sign <.

so we get

-8x < 40 and 3x < 9

we divide each "x" by its coefficient

[tex] \frac{ - 8x}{ - 8} < \frac{40}{ - 8} \: and \: \frac{3x}{3} < \frac{9}{3} [/tex]

then we get

x < -5 and x < 3

but x is positive so it's greater than -5 so we get

x > -5 and x < 3

Answer:

The boat is 26 mi far from dock .

Step-by-step explanation:

By using PGT

P²+B² = H²

=> 10² + 24² = c²

=> 100 + 576 = c²

=> 676 = c²

=> √676 = c

=> 26 = c

Answer:

26 miles

Step-by-step explanation:

We can use Pythagorean's Theorem for right triangles which states that:

[tex]a^2+b^2=c^2[/tex]

The values 'a' and 'b' are the shorter sides of the triangle, while the value 'c' is the longest side of the triangle. We are given the two shorter sides 'a' and 'b', so let's now find 'c':

[tex](24mi)^2+(10mi)^2=c^2[/tex]

[tex]576mi^2+100mi^2=c^2[/tex]

[tex]c^2=676mi^2[/tex]

[tex]c=\sqrt{676mi^2}[/tex]

[tex]c=26mi[/tex]
