6 - 0.3 = 5.7 gallons
5.7/4 = 1.425 gallons in each bottle
To find y you must recognize that 141+3y=180 . You know this since half of a circle is 180, and a line is basically half a circle if you arc from end point to end point.
You can then subtract 141 from both sides,
3y = 39
Then divide both sides by 3,
y=13
You would want to use 39° for 3y° since 3·13= 39.
A triangle can only contain 180°, so you would add 68 and 39 together and then subtract this from 180 to give you x.
68 + 39 + x = 180
107 + x = 180
x = 73
Answer:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%
Step-by-step explanation:
Let X the random variable that represent the circumferences of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%
For direct variation:
y = kx
-12 = 9k
k = -12/9 = -4/3
Therefore, the required equation is y = -4/3 x
Answer:
Step-by-step explanation:
A parameter describes a population, and a statistic describes a sample.
The first one is a statistic. A sample was surveyed.
The second one is a parameter. It describes the entire soccer team.
The third one is a statistic. A sample was surveyed.
The fourth one is a parameter. It describes the entire golf team.
