Answer:

We can expect $1.7 off

Step-by-step explanation:

We are given 10 fortune cookies out of which

$1 off  = 7 cookies

$2 off = 2 cookies

$6 off = 1 cookie

Probability

A = drawing $1 off cookies    P(A) = 7/10

B= drawing $2 off cookies    P(B)  = 2/10

C= drawing $6 off cookie      P(B)  = 1/10

Expectation = 1*7/10 + 2*2/10+ 6*1/10

                   = 7/10  +   4/10  + 6/10

                   =  17/10 = $1.7 off

One side of a triangle measures 10 inches. Which could be the measures of the other 2 sides of the triangle?
stellarik [79]

Answer:

B. 4 and 6 in

Step-by-step explanation:

The triangle inequality rule states: the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.

So for the first qualification, we can eliminate A, C, and D. Therefore the answer is B, 4 & 6 in

Write an equation of the line that passes through (-5, -2) and is parallel to y = 2/3x+1
rewona [7]

Answer:

Step-by-step explanation:

Ok, so the slope has to be the same because it’s parallel.

y=2/3x+1

slope=2/3

y=-2

x=-5

y=2/3x+ what

-2=-3 1/3 + what

1 1/3

hence, y=2/3x+4/3

In parallelogram HJKL if HM=12 find HK.<br> K<br> M<br> M<br> H<br> L
Anestetic [448]

Answer:

HK = 24

Step-by-step explanation:

HK and JL are diagonals of the parallelogram.

Recall that diagonals of a parallelogram bisect each other. This implies that, they divide each other into equal parts.

Therefore,

HK = 2(HM)

HM = 12

Thus,

HK = 2(12)

HK = 24

11. You are asked to put a V-shaped roof on a house. The slope of the roof is 53°. What is the measure of the angle needed at th
Anestetic [448]
The question said that it told you the base angles. A roof would have two equal base angles. The base angles= 53

All the angles of a triangle each 180, (the roof is shaped like a triangle)

So, let's make x the missing angle.

53(2)+x=180

106+x=180

Subtract 106 on both sides.

180-106= 74

The vertex angle is 74.

I hope this helps!
