Answer:

  • the domain of the function g(x+4)-7 is (-\infty,-2);
  • the range of the function g(x+4)-7 is [-10,\infty).

Step-by-step explanation:

If the function f(x) has the domain [-3,\infty) and the range (-\infty,2), then the function g(x)=f^{-1}(x) has the domain that id the function's f(x) range and the range that is function's f(x) domain. Therefore,

  • the domain of the function g(x) is (-\infty,2);
  • the range of the function g(x) is [-3,\infty).

The function g(x+4)-7 is the translation of the function g(x) 4 units to the left and 7 units down, hence

  • the domain of the function g(x+4)-7 is (-\infty,-2);
  • the range of the function g(x+4)-7 is [-10,\infty).

notsponge [240]

Answer:

z=0.842

And if we solve for a we got

\mu=13.16 +0.842*3=15.69

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the hourly rates of a population, and for this case we know the distribution for X is given by:

X \sim N(\mu,3)  

For this part we want to find a value a, such that we satisfy this condition:

P(X>13.16)=0.20   (a)

P(X   (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.80 of the area on the left and 0.20 of the area on the right it's z=0.842. On this case P(Z<0.842)=0.8 and P(z>0.842)=0.20

If we use condition (b) from previous we have this:

P(X  

P(z

But we know which value of z satisfy the previous equation so then we can do this:

z=0.842

And if we solve for a we got

\mu=13.16 +0.842*3=15.69

Once again... we almost finish, solve for x
algol13

Answer:

x = 34

Step-by-step explanation:

Angles are supplementary:

x + 7 + 4x + 3 = 180

5x + 10 = 180

5x = 170

x = 34

Find the length of the missing side Geometry
leonid [27]

7.

Since it is a right triangle we can use Pythagorean Theorem to solve.

A^2+B^2=C^2

We are given C and B. We are solving for A, so we can input what we know.

A^2+24^2=25^2

A^2+576=625

A^2=49

A=7

Therefore, the missing side is equal to 7.
