There are 8 red, 5 yellow, and 7 green cubes in a box. What is the probability of drawing a yellow cube and then a green cube, if the first cube is not replaced before the second cube is drawn? *
A)1/2
B)1/4
C)7/80
D)7/76
Will give extra points and brainlist
Answers
Answer:
D) 7/76
Step-by-step explanation:
There are 20 cubes in total
So our first drawing of a yellow cube is 5/20.
Our second drawing of a green cube is 7/19.
We then multiply these fractions together to get our probability.
(5/20) * (7/19) = 0.09210526315 or 7/76ths
Our answer is D

Answers
Question: In ΔRST, the measure of ∠T=90°, the measure of ∠R=6°, and RS = 3.6 feet. Find the length of ST to the nearest tenth of a foot.
Answer:
0.4 Feet
Step-by-step explanation:
From the question,
Applying
SinФ = Opposite/Hypotenuse
SinФ = ST/RS............... Equation 1
From the diagram attached below,
Given: Ф = 6°, ST = y feet, RS = 3.6 feet
Substitute these value into equation 1
Sin6° = y/3.6
make y the subject of the equation
y = 3.6(sin6°)
y = 3.6(0.1045)
y = 0.3762
y = 0.4 feet
Therefore Length ST = 0.4 feet

16) Jenna is responsible for changing the broken light bulb in a streetlamp. The streetlamp is 14 feet high. Jenna places the base of her ladder 3 feet from the base of the streetlamp. Jenna can extend the ladder from 10 feet to 14 feet. How long must her ladder be to reach the top of the streetlamp? Will her ladder work?
Answers
Use the Pythagorean theorem:
Height is 14, base is 3, so we can calculate the length required.
Length = sqrt(14^2 + 3^2)
Length = sqrt( 196 + 9)
Length = sqrt(205)
Length = 14.32 feet.
The ladder needs to be 14.32 feet. The longest her ladder can be is 14 feet so her ladder won’t work.

Step-by-step explanation:
The total stimulations in which all three elevators are working is 12(option d) by the concept of data representation.
What is data representation?Data Representation: A method for analyzing numerical data is data representation. Data representation is used to create a diagram that shows the connections between facts, ideas, information, and concepts. It is a fundamental learning technique that is clear-cut and uncomplicated. The data type in a particular domain is always what determines it. There are many various styles and sizes of graphical representations.
According to the given data:
A building has 3 elevators.
The following set of random numbers represents 20 stimulations of the elevators, with 0, 1 representing the broken elevator and 2,3,4,5,6,7,8and 9 representing a working elevator.
Stimulation data:
931 188 763 841 559 144 652 277 653 673 404 396 011 843 599 797 414 761 273 844
Now, as we observe from the given data, the stimulation in which all three elevators are working are-
763,559,652,277,653,673,396,843,599,797,273,844a total of 12 stimulations.
Thus, the total stimulations in which all three elevators are working is 12
Hence, option d is correct.

Find an equivalent expression for the missing side length of the rectangle. Then find the missing side when x=3.Round to the nearest tenth of an inch
Answers
Answer:
Base of rectangle = 23.25 units (Approx.)
Step-by-step explanation:
Given:
Diagonal of rectangle (Hypotenuse) = 8x
Height of rectangle (Perpendicular) = 2x
Find:
Base of rectangle
Computation:
Base = √Hypotenuse² - Perpendicular²
Base of rectangle = √(8x)² - (2x)²
Base of rectangle = √64x² - 4x²
Base of rectangle = √60x²
Base of rectangle = 7.75x units (Approx.)
If x = 3
Base of rectangle = 7.75x
Base of rectangle = 7.75(3)
Base of rectangle = 23.25 units (Approx.)

For part (a), you don't need to type in the "y=" portion as that is already done for you. For any answer choice involving a percentage, type in the number only. This is because the percent sign is already taken care of.
====================================================
Explanation:
Part (a)
Note how each time x goes up by 1, y drops by 0.2
We can see that
slope = rise/run
slope = (change in y)/(change in x)
slope = (-0.2)/(1)
slope = -0.2
This tells us that the battery life goes down by 20 percentage points for each hour. Note: This is not the same as saying it drops by 20% each time, as this is a subtle difference; however, I can see what your teacher is trying to say for part (b).
The y intercept is b = 1 since this is the location where the graph crosses the y axis.
The slope m = -0.2 and y intercept b = 1 leads y = mx+b to turn into y = -0.2x+1 which is the final answer for part (a).
As a way to check, plug in x = 0 and you should get y = 1. Plug in x = 1 and you should get y = 0.8, and so on. The (x,y) values should match what the graph shows.
----------------------------
Part (b)
As mentioned previously, the slope tells us how much the battery is changing. It's the rate of change. Specifically in this case, the battery is losing 20 percentage points for each hour. Your teacher should have used this careful phrasing, rather than say "the battery life goes down by 20% for each hour" but I can see what they're going for. So 20 is the answer for the first box of part (b)
The x intercept is where the graph crosses the x axis, which is x = 5 in this case. The x intercept always happens when y = 0. When y = 0, the battery is completely dead at 0%. Therefore, we can get 5 hours of battery life. The value 5 goes in the second box of part (b).
On the other end of the spectrum, the battery is 100% full when x = 0, which is at the start of everything. This is due to the y intercept b = 1.0 which represents 100%. In other words, the person starts off with a 100% charge, and they use their laptop for 5 hours, at which point the battery is at 0%. The value 100 goes in the third box for part (b)
----------------------------
Part (c)
We are asked to find the value of x when y = 0.75
y = -0.2x+1
0.75 = -0.2x+1
0.75-1 = -0.2x
-0.25 = -0.2x
-0.2x = -0.25
x = -0.25/(-0.2)
x = 1.25
After 1.25 hours the battery is at 75%

Four of the interior angles of a hexagon measure 92°, 100°, 94°, and 140°. The remaining two angles each measure (x−32)°. What is the value of x? Justify your response.
A. The sum of all interior angle measure is 540°
, so each angle measuring (x−32)° has a measure of 123°
. Thus, (x−32)°=123°, and so x=155.
B. The sum of all interior angle measure is 720°
, so each angle measuring (x−32)° has a measure of 294°. Thus, (x−32)°=294°, and so x=326.
C. The sum of all interior angle measure is 720°
, so each angle measuring (x−32)° has a measure of 147°
. Thus, (x−32)°=147°, and so x=179.
D. The sum of all interior angle measure is 540°
, so each angle measuring (x−32)° has a measure of 246°. Thus, (x−32)°=246°, and so x=275.
Answers
Answer:
The answer is x=294 (B)
Step-by-step explanation:
Remember, all interior angles of a hexagon add to 720.
So add all the given numbers first.
92+100+94+140+x= 720
426+x=720
-426 from both sides
x= 294

can somebody please describe where i put the construction marks? it’d be really helpful.
Answers
Answer:
Step-by-step explanation:
A median bisects the side it intersects with, so the first step is to bisect FG.
Set the compass slightly larger than half of FG.
Put the point on F and draw a half circle that intersects FG and faces G.
Put the point on G and draw a half circle that intersects FG and faces F.
Draw a line through the intersections of the two half circles, and the intersection of that line with FG is FG's midpoint.
Connect the midpoint with E, and the connecting line is the median.
