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=<span>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

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

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

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

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

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