What is the equation of the line that passes through the points (3, 6) and (8,4)

Lostsunrise [7]

In the equation y=mx+b, 'm' is the slope of the line and 'b' is the y-intercept.
First, you should find the slope of the line. To do this, use the equation M=y2-y1/x2-x1. Using the two given points (3,6) and (8,4), you can solve for M.
M=4-6/8-3
M=-2/5 (-0.4 in decimal form)
Now, your equation is y=-0.4x+b
Next you must solve for b to find the y-intercept. You can do this by subbing one of the given points in for x and y.
Using the point (3,6):
y=-0.4x+b
6=-0.4(3)+b
6=-1.2+b
Isolate b:
6+1.2=b
b=7.2
And now you have the equation of the line!
y=-0.4x+7.2 (IN FRACTION FORM: y=-2/5x+36/5)

A jar is filled with 74 different colored marbles, 10 of which are red, 38 of which are blue, and 26 of which are green. A playe

Alex_Xolod [135]

Solution :

Colored marble Prize

Red ---- 10 20

Blue --- 38 10

Green --- 26 5

P(red) = 10/74 = 5/37

P(blue) = 38/74 = 19/37

P( green) = 26/74 = 13/37

Therefore,

X → Red Blue Green

P(X) 5/37 19/37 13/37

The expected values are :

$$20 \times \frac{5}{37} - 10 \times \frac{19}{37} - 5 \times \frac{13}{37}$

= -4.189

Thus it is not profitable to play the game.

Find the measure of the numbered angles in rhombus ABCD

sasho [114]

Answer:

see the explanation

Step-by-step explanation:

we know that

In a Rhombus opposite angles are congruent and consecutive angles are supplementary

The diagonals are perpendicular and bisect the angles

so

step 1

Find the measure of angle 4

we know that

$m\angle 4=27^o$ --->by the diagonals bisect the angles

step 2

Find the measure of angle 1

we know that

$m\angle 1=27^o$ ----> by opposite angles are congruent

step 3

Find the measure of angle 2

we know that

$m\angle 1=m\angle 2$ ----> by the diagonals bisect the angles

so

$m\angle 2=27^o$

step 4

Find the measure of angle 3

we know that

$m\angle 3=90^o$ ----> by the diagonals are perpendicular

step 5

Find the measure of angle 5

we know that

$m\angle 5+27^o=90^o$ ----> by complementary angles

$m\angle 5=90^o-27^o=63^o$

step 6

Find the measure of angle 6

we know that

$m\angle 6=m\angle 5$ ----> by the diagonals bisect the angles

$m\angle 6=63^o$
