Given that z is a standard normal random variable, find z for each situation. The area between 0 and z is .4750. Answer The area
algol13

Answer:

P(0

And solving for z we have

P(Z

And we can find the value for z with the following excel code:

"=NORM.INV(0.975,0,1)"

And we got z =1.96

P(Z>z)= 0.1314

And we can use the complement rule and we got:

P(Z>z) = 1-P(Z

P(Z

And we can find the value for z with the following excel code:

"=NORM.INV(0.8686,0,1)"

And we got z =1.120

P(Z

And we can find the value for z with the following excel code:

"=NORM.INV(0.67,0,1)"

And we got z =0.440

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

We want this probability:

P(0

And solving for z we have

P(Z

And we can find the value for z with the following excel code:

"=NORM.INV(0.975,0,1)"

And we got z =1.96

For the next part we want to calculate:

P(Z>z)= 0.1314

And we can use the complement rule and we got:

P(Z>z) = 1-P(Z

P(Z

And we can find the value for z with the following excel code:

"=NORM.INV(0.8686,0,1)"

And we got z =1.120

For the next part we want to calculate:

P(Z

And we can find the value for z with the following excel code:

"=NORM.INV(0.67,0,1)"

And we got z =0.440

Peter says, "If you subtract 13 from my number and multiply the difference by -3, the result is
Art [367]

Answer:

Peter's number is 36.

Step-by-step explanation:

If you subtratct 13 from 36, you get 23.

If you multiply that times -3, you get -69.

(The way I got 23 was by dividing -69 and -3)

I hope this helped you even though it's late.

** This is<br> Directions: Find each missing measure.<br> 1.<br> 15<br> 26°<br> х
suter [353]

Answer:

x = 13.48

Step-by-step explanation:

Given that,

Angle, \theta=26^{\circ}

base, b = x

Hypotenuse, H = 15

We need to find the measure of x. It can be solved using trigonometry i.e.

\cos\theta=\dfrac{b}{H}

Put all the values,

\cos(26)=\dfrac{x}{15}\\\\x=15\times \cos(26)\\\\x=13.48

So, the value of x is equal to 13.48.
