Write two equations so that each have variables on both sides and a solution of 1/2

1 answer:

3 0

The solution will be:

x= $\frac{1}{2}$

we can start here and just modify this, for example: add x to both sides:

2x= $\frac{1}{2}$ +x

this is one such equation!

and further let's add 5 to both sides

2x+5=5 $\frac{1}{2} +x$
and another such equation!

For part B problem 1. It's telling you to add the numbers from the difference high row and if your answer is not an integer, what two integers is it between.

-7 + -7 + 2 + 5 + -3 + -2= -12

Then you do the same for problem 2 But this time with the difference low row

0 + -3 + -7 + -1 + 1 + 0= -10

now you determine if both answers are integers or not

A sales completion team, aiming to reduce the shipment time of urgent orders, studies the current process and finds that the cur

Answer:

$P(1$

And we can find this probability with thi difference:

$P(-2$

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.

$P(-2$

So then we expect about 72.5% of the current shipment times between 1 and 5 days

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 current shipment time of a population, and for this case we know the distribution for X is given by:

$X \sim N(4,1.5)$
