Answer:
≈ 3927 litres
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = Ah ( A is the area of the base and h the height )
Note that h of oil = 250 ÷ 2 = 125 cm ( since half full )
V = πr²h
= π × 100² × 125 = 1250000π cm³ ( divide by 1000 )
= [tex]\frac{1250000\pi }{1000}[/tex] = 1250π litres ≈ 3927 litres ( to the nearest litre )
Answer:
3927
Step-by-step explanation:
first u have to find volume of cylinder its volume is
V=
[tex]\pi \times radius ^{2} \times height[/tex]
so it become 7853981cm^3 then convert it into Liters as you know 1liter=1000cm^3
so divide your volume with 1000 and the answers
is 7853 so as u know that it is half filled than divied ur 7853 by 2 then final ans is 3927

What is the equation of the line that passes through the point (-7, 2) and has a
slope of -1?
Answers
Answer: y= -1x - 5
Step-by-step explanation:
The equation has to be in slope-intercept form which uses the formula
y=mx+b where m is the slope and b is the y-intercept.
So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.
the x coordinate is -7 and the y coordinate is 2
2 = -1(-7) + b
2 = 7 + b
-7 -7
b = -5 the y intercept is -5
Now the equation will be y= -1x - 5

Answers
Answer:
Normally Distributed.
Explanation:
After plugging all those numbers into a calculator you can see that the graph isn't left skewed, making both "left skewed" and "all of the above" not an answer. "correlated with a second set of data" is also wrong since there was no second set of data given. That leaves you between "uniformly distributed" and "normally distributed" This graph doesn't show a uniformly distributed graph, which leaves you with the final answer, normally distributed.

Answers
Answer: Lin is the most consistent and I would want to have them on my team.
Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since
range = max - min
So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.

Step-by-step explanation:
It is given that,
6.3% of the 6,540,000 Indiana residents were listed as Hispanic or Latino in 2012. We need to find the no of people for this.
Using the concept of percentage as follows :

Find k so that the distance from (–3, –1) to (k, 5) is 10 units.
Answers
Answer:
k = - 11, 5
Step-by-step explanation:
By distance formula:
[tex] \sqrt{ \{ {k - ( - 3) \}}^{2} + \{5 - ( - 1) \}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(5 + 1)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(6)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + 36 } = 10 \\ \\ (k + 3)^{2} + 36 = {10}^{2} \\ ..(squaring \: both \: sides) \\ {k}^{2} + 6k + 9 + 36 = 100 \\ {k}^{2} + 6k + 45 - 100 = 0 \\ {k}^{2} + 6k - 55 = 0 \\ {k}^{2} + 11k - 5k - 55 = 0 \\ k(k + 11) - 5(k + 11) = 0 \\ (k + 11)(k - 5) = 0 \\ k + 11 = 0 \: or \: k - 5 = 0 \\ k = - 11 \: or \: k = 5 \\ \\ \huge \red { \boxed{k = \{ - 11, \: 5\}}}[/tex]
There are two solutions for [tex]k[/tex]: 5 and -11.
In this case, we must use the Length Equation for Line Segment to solve for [tex]k[/tex], whose formula is described below:
[tex]l = \sqrt{(x_{B}-x_{A})^{2}+ (y_{B}-y_{A})^{2}}[/tex] (1)
Where:
[tex](x_{A}, y_{A})[/tex] - Coordinates of the initial endpoint.
[tex](x_{B}, y_{B})[/tex] - Coordinates of the final endpoint.
[tex]l[/tex] - Length of the line segment.
If we know that [tex](x_{A}, y_{A}) = (-3, -1)[/tex], [tex](x_{B}, y_{B}) = (k, 5)[/tex] and [tex]l = 10[/tex], then the equation is expanded into this form:
[tex](k+3)^{2}+[5-(-1)]^{2} = 100[/tex]
[tex]k^{2}+6\cdot k + 9 + 36 = 100[/tex]
[tex]k^{2} + 6\cdot k -55 = 0[/tex]
The roots of this Second Order Polynomial are determined by Quadratic Formula:
[tex]k = 5[/tex] or [tex]k = -11[/tex].
There are two solutions for [tex]k[/tex]: 5 and -11.

[tex]\frac{-7+x^{2} }{2} = -4\\\frac{1+y^{2} }{2} =1[/tex] You multiply -4 by 2 which gives you -8 then you multiply 1 by 2 which gives 2.
Then you create the equations [tex]-7 + x^{2} = -8\\1 + y^{2} = 2[/tex] you substitute -7 for +7 and add 7 to -8 which gives -1 ([tex]x^{2}[/tex]) and subtract 1 from 2 which gives you 1 ([tex]y^{2}[/tex])

When we roll one die, we have a 1 in 6 probability of getting any particular number on the die. When we roll a pair of dice, there are 36 different pairs that can be produced, yet only 11 actual distinct values. Explain how the probability associated with the roll of each individual die in the pair explains the higher variability in the total outcome of the roll of each pair. How do the concepts of permutations and combinations apply to this example
Answers
Answer:
The probability of an event occurring depends on the sample space and the frequency of the event
permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6
Step-by-step explanation:
The probability of an event occurring depends on the sample space and the frequency of the event
The total outcomes of rolling a pair of fair dice would be = ( total outcome of single dice A * total outcome of single Dice B ) = 6 * 6 = 36. and this is because the Two dice are independent of each other. hence there is a higher variability in the determining the possibility of a particular number ( 1,2,3,4,5,6) showing up when a pair of dice is rolled due to the larger sample space. permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6

These are corresponding angles since they both connect a parallel line and the transversal. This means they are congruent and have the same value. So, we can set up the following equation.
8x-8=5x+25
Subtract 5x from both sides.
3x-8=25
Add 8 to both sides.
3x=33
Divide both sides by 3.

Have a wonderful day! :D
Answer:
x = 11
∠B = 80
Step-by-step explanation:
∠A = ∠B
where
∠A = 8x - 8°
∠B = 5x + 25°
8x - 8° = 5x + 25°
8x - 5x = 25 + 8
3x = 33
x = 33/3
x = 11
plugin x into ∠B = 5x + 25°
∠B = 5x + 25°
∠B = 5(11) + 25°
∠B = 80
