Answer

a) PQ = 50

b) PC = 18

PY = 27

c) ZC = 6

ZQ = 18

Explanation

Centroid is a point inside a triangle where all lines drawn from each vertex to the midpoints of opposite side intersect.

Part a

X is the midpoint of PQ. SoPX = XQ.

If PX = 25,

then PQ = 2PX

PQ = 2×25

PQ = 50

Part b

The centroid is alway two thirds away from the vertex.

Also PC = twice CY

PC = 2×9

PC = 18

So, if CY = 9, then PY = 3 × 9

PY = 27

Part c

(i) The centroid is alway two thirds away from the vertex.

If ZC = 12, then CZ =(1/2)QZ

CZ = (1/2) × 12

CZ = 6

(ii) The centroid is alway two thirds away from the vertex.

So, if CZ = 6, then QZ =3 CZ

QZ = 3×6

QZ = 18

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ

ZanzabumX [31]

Answer:

y = $\frac{2}{3}$ x+ $\frac{13}{3}$

Step-by-step explanation:

Okay, the first thing to do here is calculate something known as the "slope".

We know two points are ( 1 , 5 ) and ( − 2 , 3 )

The slope is represented by "m" in the standard form: y = mx+b

The slope is also known as the rise over the run, y2-y1/x2-x1 = $\frac{3-5}{-2-1}$ = $\frac{2}{3}$

=> the standard form: y = $\frac{2}{3}$ x+b

Now we have to use the slope, and resubstitute another point to get b

5 = $\frac{2}{3}$ (1) + b

<=> b= 5- $\frac{2}{3}$ = $\frac{13}{3}$

So the equation that model the line is: y = $\frac{2}{3}$ x+ $\frac{13}{3}$

Total freshman = 58. Number of freshman who prefer cheese toppings= 14. Determined the probability that a freshman prefer cheese

Yakvenalex [24]

Answer:

The probability that a freshman prefer cheese toppings is 0.241

Step-by-step explanation:

Probability of any event E = $\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}$

Here, let E : Event of choosing cheese toppings

So, the number of favorable outcomes = 14

Total number of outcomes = 58

So, $P(E) = \frac{\textrm{Number of students who like cheese toppings}}{\textrm{Total number of students}}$

or, P(E) = $\frac{14}{58} = 0.241379$

So,the probability that a freshman prefer cheese toppings is 0.241379

Rounding of 0.241379 to the <u>nearest thousandth</u>, we get

Here , in 0.241379 thousandth digit is 3, and 3 < 5,

so the value of P(E) = 0.241

Please I want the area and perimeter of this shape!!<br> With steps and explanation please!!

worty [1.4K]

For perimeter you will add each side together so

8ft+22ft+12ft+16ft=58

So your perimeter is 58ft.

For area your going to divide the shape into 2 to get the area as this is an irregular shape, so

Base 1+base2x height / by 2

22+8 x4/2

30x4/2

120/2

If you’re wondering how I got 4 I subtracted 16 with 12 to know what the height was. Good luck!!
