probability that is not red=
[tex] \frac{12}{284} [/tex]
Step-by-step explanation:
i think that is the portability that is not red
The probability that the light is not red is 13/17
How to determine the probability?The given parameters are:
Green = 2 minutes
Red = 40 seconds
Yellow = 10 seconds
Express green as seconds
Green = 120 seconds
The probability that the light is red is:
P(Red) =Red/Total
This gives
P(Red) = 40/(120 + 40 + 10)
Divide
P(Red) = 4/17
The probability that it is not red is:
P(Not Red) = 1 - P(Red)
This gives
P(Not Red) = 1 - 4/17
Subtract
P(Not Red) = 13/17
Hence, the probability that the light is not red is 13/17

Triangle G F E is cut by line segment H J. Line segment H J goes from side G E to F E. The length of G F is 4 x minus 4, the length of H J is x + 3, and the length of J E is x minus 1.
If H is the midpoint of GE and J is the midpoint of FE, determine the following lengths.
HJ =
JE =
Answer:
HJ = 8 JE = 4
Step-by-step explanation:
it is given that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem the line segment connecting the midpoint of two sides is parallel to the three side and its length is half of the third side. since JH is connecting the midpoints.
HJ= 1/2 (GF)
x + 3 = 1/2 (4x - 4)
x + 3 = 2x - 2
x = 5
^ Thus meaning the value of x is 5.
Now you just fill into your equations:
HJ = x + 3 = (5) + 3 = 8
JE = x - 1 = (5) - 1 = 4
Therefore, HJ = 8; JE = 4.
Answer:
HJ = 8
JE = 4

Kathleen, a professional golfer, had an average score last season
of 80 points. This season, her average score has been 72 points.
What is the percent of decrease in Kathleen's average score?

How can you determine the part of an hour that is 15 minutes?
Answer:
You'll need to convert the minutes part to hours. 15 minutes times 1 hour per 60 minutes will make the conversion to hours and minutes will cancel out. 0.25 hours times 60 minutes per 1 hour = 0.25 hr × (60 min/ 1hr) = (0.25 × 60) min = 15 minutes.

None of he choices are correct. Now before you say I'm wrong, look at any one of the unknown angles. You can plainly see that they each are greater than 90 °.
x = 120°
Step-by-step explanation:
5 sides
(180 x 5) - 360 = 540° total of interior angles
540 - 90 - 90 = 360° total for the 3 unknown angles
x = 360/3 = 120°

Solve the following:
⅜x - 16 = 16
Answer:
x = 256/3
Step-by-step explanation:
3/8x - 16 = 16
Add 16 to both sides
3/8x = 32
Multiply 8 by both sides
3x = 256
Divide 3 by both sides
x = 256/3 or 85.3333333

A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 4 milliliters of compound B. If a chemist wants to make 378 milliliters of the drug, how many milliliters of compound B are needed?
Answer:
216 milliliters
Step-by-step explanation:
Since, there are 3 milliliters of compound A used for every 4 milliliters of compound B.
Therefore,
A : B = 3 : 4
Let the common multiplier of the given ratios be x.
So, A = 3x & B = 4x
Since, chemist wants to make 378 milliliters of the drug.
Therefore, total volume of drug = 378 milliliters.
3x + 4x = 378
7x = 378
x = 378/7
x = 54
4x = 4*54 = 216
Thus, 216 milliliters of compound B are needed.
A bottle holds exactly 2/3 pint of liquid. How many 2/3-pint bottles can be filled from a 24-pint container
Answer:
36 number of 2/3-pint bottles can be filled from a 24-pint container

Suppose WX = 4x - 8 and WZ = 2x + 2. Solve for x
Answer: 5
Step-by-step explanation:
Because the shape is a kite we can tell that WX and WZ are congruent.
So 4x-8 = 2x+2
Add 8 to both sides
4x = 2x+10
Subtract 2x
2x = 10
Divide by 2
x = 5
