Answer:

-6

Step-by-step explanation:

When multiplying a number by a -1, it's sign switches. So if the number is posative(+ or has no sign in front) then it becomes negative. If it was originallt negative(- in front) then it becomes posative. Since 6 is positive it becomes -6

Answer:

a) $P(2.9$

And we can find this probability with the following difference:

$P(-1$

b) $P(2.9$

And we can find this probability with the following difference:

$P(-3.5$

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".

Part a

Let X the random variable that represent the diameters of a population 1, and for this case we know the distribution for X is given by:

$X \sim N(3,0.1)$

Where $\mu=2$ and $\sigma=0.1$

We are interested on this probability

$P(2.9$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(2.9$

And we can find this probability with the following difference:

$P(-1$

Part b

$X \sim N(3.04,0.04)$

$P(2.9$

And we can find this probability with the following difference:

$P(-3.5$

Stanley drew a rectangle that was w inches wide. The expression 2(2w)+2(w) represents the perimeter of the rectangle Stanley dre

k0ka [10]

The complete question in the attached figure

we know that
[the perimeter of a rectangle]=2*[length+width]
the perimeter=2(2w)+2(w)----> 2*[2w+w]------> 4w+2w----> 6w
P=6w-------> the perimeter is 6 times the width
so
in this problem
length=2w
width=w

statements
A) The perimeter is 6 inches more than the width------> is not correct
Because we were not given specific lengths

B) The perimeter is 6 times the width.------> is correct
P=6*w

C) The perimeter is 2 inches more than the width.------> is not correct
Because we were not given specific lengths

D) The perimeter is 2 times the width------> is not correct
because the perimeter is 6 times the width

the answer is the option
B) The perimeter is 6 times the width
