Answer:  37.778 degrees

Step-by-step explanation:

The third digit to the right of the decimal is thousandths. If the next digit to the right of that is 5 or more, add one to the thousandths. Otherwise leave it as is. Just drop everything to the right of the place you rounded to.

7 is greater than 5, so add 1 to the 7 in the thousandths place and get

37.778

Serious answers only. Do not answer if you dont know please!How does the graph of the circle described by x^2 + (y-7)^2 = 49 cha
Vladimir79 [104]

Answer:

  • The circles radious increases
  • The circles moves left
  • The circles moves down

Step-by-step explanation:

  • The equation of a circle can be written as (x-a)^2+(y-b)^2=r^2, where "r" is the radious, and (a,b) are the coordenates in the axis x and b respectively.
  • Then, in the first circle the coordenates are (0,7), which means that the circle will be center there, and the radious is 7 (\sqrt{49}).
  • The second circle have different coordenates: (-5,4), which means that the circle has moved left (from 0  to -7 in the x axis) and down (from 7 to 4 in the y axis). Additionally, its radious has increased from 7 (\sqrt{49}, from 8 (\sqrt{64}).
  • See the attached figure please.
  • Then, the <u>correct answers</u> are:
  1. The circles radious increases (from r=7 to r=8)
  2. The circles moves left (from x=0 to x=-5)
  3. The circles moves down (from y=7 to y=4)

Bottling cola A bottling company uses a filling machine to fill plastic bottles with cola. The bottles are supposed to contain 3
erik [133]

Answer:

P(X

And we can find this probability using the normal standard table or excel:

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

X \sim N(298,3)  

Where \mu=298 and \sigma=3

We are interested on this probability

P(X

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(X

And we can find this probability using the normal standard table or excel:

P(Z
