Picture relating to the required graph is attached below

Answer:

C. (3, 13)

Step-by-step explanation:

According to the inspected scatterplot, we could actually observe a possible data trend which is where the majority of the samples are clustered. In a graphical representation of data, data points which deviates away from the trend of the majority of the points are considered as outliers. In the scenario above, the point (3, 13) seems too far off from the actual trend line, thus showing a greater y value than the pattern actually predicts.

Solve for x in the simultaneous equation 2x+y=3 ,5x-2y=12

sp2606 [1]

Answer:

x = 2

Step-by-step explanation:

Given the 2 equations

2x + y = 3 → (1)

5x - 2y = 12 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the y- term

4x + 2y = 6 → (3)

Add (2) and (3) term by term

(5x + 4x ) +( - 2y + 2y) = 12 + 6 , that is

9x = 18 ( divide both sides by 9 )

x = 2

From a train station, one train heads north, and another heads east. Some time later, the northbound train has traveled 12 miles

tigry1 [53]

9514 1404 393

Answer:

20 miles

Step-by-step explanation:

The north and east distances form the legs of a right triangle. The straight-line distance between the trains is the hypotenuse of that triangle. The Pythagorean theorem can be used to find the length of the hypotenuse (d).

d² = 12² +16²

d² = 144 +256 = 400

d = √400 = 20

The two trains are 20 miles apart.

<em>Additional comment</em>

You may recognize the given distances are in the ratio 3 : 4. You may recall that side ratios of 3 : 4 : 5 make a right triangle. If so, you recognize that the straight-line distance is (4 miles)×5 = 20 miles. (3:4:5 right triangles show up often in algebra and geometry problems, so might be something you want to look for.)

I need help it’s hard please help

mel-nik [20]

Woohoo
okay, so is z less than or grater than 2/5? greater so you would just label your graph then where ever you put 2/5 you put all the other dots or an arrow going to the right but put an open circle then the arrow something like this
o------------>
(2/5--------->)
sorry if confusing

A piece of rope is 33 1/3 yards long and was cut into equal pieces. How many yards was each piece?

malfutka [58]

Answer:

<h2> 11 ¹/₉ yards</h2>

Step-by-step explanation:

You didn't say how many pieces. My answer is for 3 equal pieces. $33\frac13\div3=(33+\frac13)\div3=33\div3+\frac13\div3=11+\frac13\times\frac13=11+\frac19=11\frac19$

For two it would be:

$33\frac13\div2=(33+\frac13)\div2=33\div2+\frac13\div2=16\frac12+\frac13\times\frac12=\\\\=16\frac36+\frac16=16\frac46=16\frac23$
