Answer: p = 7.50h

Step-by-step explanation: If you compare the hours worked (h) with pay (p) you'll find that the pay is always 7.50 times the hours worked in dollars. Hence, p = 7.50h.

Liono4ka [1.6K]

Answer:

His book was opened at Page no.296 and Page no.297

Step-by-step explanation:

Let the page number of one page be x

Page number of page facing page no. x = x+1

We are given that the product of the facing pages was 87,912.

So, x(x+1)=87912

$x^2+x=87912$

$x^2+x-87912=0$

$x^2-296x+297x-87912=0$

$x(x-296)+297(x-296)=0$

(x+297)(x-296)=0

x=296,-297

Since Page no. cannot be negative

So, x=296

x+1=296+1=297

So, his book was opened at Page no.296 and Page no.297

NeX [460]

Answer:

$z=-0.994$

And if we solve for a we got

$a=3 -0.994*0.4=2.6024$

So the value of height that separates the bottom 16% of data from the top 84% is 2.6024 years

The answer rounded would be 2.6 years approximately

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 shelf life of a population, and for this case we know the distribution for X is given by:

$X \sim N(3,0.4)$

Where $\mu=3$ and $\sigma=0.4$

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

$P(X>a)=0.84$ (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 0.16 of the area on the left and 0.84 of the area on the right it's z=-0.994. On this case P(Z<-0.994)=0.16 and P(z>-0.994)=0.84

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:

$z=-0.994$

And if we solve for a we got

$a=3 -0.994*0.4=2.6024$

So the value of height that separates the bottom 16% of data from the top 84% is 2.6024 years

The answer rounded would be 2.6 years approximately
