Hello! Answer: Area = 66

What i did was cut them into triangles and used formula for finding triangles

I did 3.3 x 4 = 13.2 then I divide 2 and get 6.6

maks197457 [2]

Answer:

first share 2x=36

Second share=5x=90

Step-by-step explanation:

Ratio 2:5

Share=126

Let first share=2x

Second share=5x

So 2x+5x=126

7x=126

X=126/7

X=18

So first share 2x=36

Second share=5x=90

I NEED HELP BADLY!!!
DaniilM [7]
Vertical angles are where the top equals the bottom or the left equals the right angle. So we would do:
8x - 13 = 5x + 8
And then substitute.
3x = 21
x = 7

vitfil [10]

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
