In the data set (0,-1);(-2,4);(-4,-8);(-1,5);(2,1);(3,-2);(-1,2)},which point is a possible outlier?

1 answer:

6 0

If it’s possible just graph:
Here you can see (-4,-8) is far away from the other points.

If you want a mathematical explanation basically look for trends in the data, and the rest of the points trend negative linear.

If you want to use formulas or equations there’s a very complicated one online, that is very difficult to understand.

Ed bought 3 liters of water, 2,750 milliliters of sports drinks, and 2.25 liters of juice. For numbers 4a-4e, select True or Fal

Naily [24]

<span>4a) 1000 milliliters = 1 liter, thus 3 liters = 3 x 1000 = 3000 milliliters.
Thus Ed bought 3000 - 2750 = 250 more water than sports drink.
Therefore, Ed bought 250 milliliters more water than sports drink is True.

4b) Ed bought 3 - 2.25 = 0.75 more water than juice.
Therefore, Ed bought 1.25 liters more water than juice is False.

4c) Ed bought 2.25 liters = 2.25 x 1000 = 2250 milliliters of juice.
Thus, Ed bought 2750 - 2250 = 500 more sports drink than juice.
Therefore, Ed bought 50 milliliters more sports drink than juice is False.

4d) Ed bought 2750 milliliters = 2750 / 1000 = 2.75 liters of sports drink.
Ed bought 2.75 - 2.25 = 0.5 liters more sports drink than juice.
Ed bought 0.5 liter more of sports drink than juice is True.

4e) Ed bought 3000 milliliters of water and 2250 milliliters of juice.
Ed bought 3000 - 2250 = 750 more milliliters of water than juice.
Therefore, Ed bought 75 milliliters more water than juice is False.</span>

Which is the graph of g(x)=10/x

crimeas [40]

Answer:

Check the attached graph

Step-by-step explanation:

Given equation is $g\left(x\right)=\frac{10}{x}$ .

Now we need to graph the given equation $g\left(x\right)=\frac{10}{x}$ ..

Clearly it is not linear as equation is not of the form $y=mx+b$ . So we need to find some points on given equation $g\left(x\right)=\frac{10}{x}$ . by plugging some random values of x like -5,-3,1,... etc.

for x=-5, we get:

$g\left(x\right)=\frac{10}{x}$

$g\left(-5\right)=\frac{10}{-5}=-2$ .

Hence first point is at (-5,-2). Similarly we can find more points and graph those points.

x can't be 0 as division by 0 is not defined so it will have vertical asymptote at x=0.

Since degree of numerator is less than degree of denominator so y=0 will be horizontal asymptote.

Now join those points by a curved line to get final graph.

What is the equation of a line that passes through the point (1, 8) and is perpendicular to the line whose equation is y=x2+3 ?

Nonamiya [84]

<span>Perpendicular lines' slopes are reciprocals of one another. So we know the perpendicular line will have a slope of 1/2. Then we can use our points to find the rest. 8=1/2(1)+b 8=0.5+b 7.5=b y=2x+b</span>

Given: rectangle ABCD is similar to rectangle ZBXY. If ZY = 5, XC = 3, DC = 4, then XY =

soldier1979 [14.2K]

Answer:

The length of XY is either 10 or 2.5.

Step-by-step explanation:

Given information: ZY = 5, XC = 3 and DC = 4.

Case 1: Rectangle ABCD is smaller than ZBXY.

The opposite sides of the rectangle are same.

$ZY=BC+XC$

$5=BC+3$

$2=BC$

The length of ABCD is 4 and width of ABCD is 2. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.

$\frac{4}{XY}=\frac{2}{5}$

$\frac{4\times 5}{2}=XY$

$10=XY$

Therefore the value of XY is 10.

Case 2: Rectangle ABCD is larger than ZBXY.

$ZY=BC-XC$

$5=BC-3$

$8=BC$

The length of ABCD is 4 and width of ABCD is 8. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.

$\frac{4}{XY}=\frac{8}{5}$
