You Must Solve For The Value Of X To Make The Equation True.
So, There Are Two Ways We Could Try This:
Guess And Check
Or
Solve

I Am Going To Show You How To Solve This Because That Is What You Need To Know. So, We First Need To Look At It.

6x + 3 = 2x + 8

So, we need to subtract 3 from the right side's 8 to begin.
The equation becomes:

6x = 2x + 5

Now, We Need To Simplify The 2x. Subtract 2x from 6x.
The Equation Becomes:

4x = 5

Now, Divide.

4x/4 = 1x = X

So,

X = 5/4

5/4 = 1 and 1/4

So

X = 1 ¼

The heights of baby giraffe are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. If 100 b

ANEK [815]

Answer:

$P(\bar X$

And we can solve this using the following z score formula:

$z = \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And if we use this formula we got:

$z = \frac{63-63.6}{\frac{2.5}{\sqrt{100}}}= -2.4$

So we can find this probability equivalently like this:

$P( Z$

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

$X \sim N(63.6,2.5)$
