Answer:
Expected number of winners with 52 contestants:52*5/13 = 20.The experiment result is almost twice less (12 vs 20).In order to change the results of experimental probability some of the letters may need swapped, (probably the letters are in alphabet order) but for this we need more data.
Step-by-step explanation:
Experimental probability is probability that is determined on the basis of the results of an experiment repeated many times. Theoretical probability is probability that is determined on the basis of reasoning. Probability is a value between (and including) zero and one.

Answer:
yes it's similar triangle because it has same shape but size is not equal
which is the solutions to the system of equations shown { 3x - y = 6 and here is the other equation{ x - 2y = -18
Answer:
(6, 12)
Step-by-step explanation:
{ 3x - y = 6
{ x - 2y = -18
by using elimination:
6x -2y=12
x - 2y= -18
________-
5x = 30
x = 6
y = 18-6 = 12
the solutions = {(6, 12)}
Sharon started driving on the highway in the morning. The equation m=60h represents the number of miles, m, that Sharon has driven on the highway in h hours. Four other cars are on the same highway. click on all the graphs that represent cars moving faster than Sharon's car.
Answer: car 1, and car 4
Step-by-step explanation: if you look at the graphs you would have to look at where 1 hour would hit 60. If it’s past 60, the car is moving faster than sharon. Hope this helps!

a square garden plot has an area of 828 square feet. what is th eexact value of the one side of the garden
Answer:
B - 6sqrt(23) ft.
Step-by-step explanation:
Area = (Side)^2 = 828.
Side = sqrt(828) = sqrt(36*23) = 6 sqrt(23).
So B - 6sqrt(23) ft.

Andrew had 40 dollars to spend on paying the paint store was having a sale each color comes in one gallon container that cost $12 each 3/8 of a gallon is needed to paint each wall will he have enough money to buy for the room explain your answer there are four walls to be painted
Answer:
yes, he would have enough money
He would need a total of 1.5 gallons to paint the wall .
the cost of 1.5 gallons is $18 dollars.
Andrew has 40. he has enough money
Step-by-step explanation:
total gallon needed to pain four walls = 3/8 x 4 = 1 1/2 gallons
total cost of 1 1/2 gallons = 1 1/2 x $12
to calculate this amount convert 1 1/2 to improper fraction
to convert to improper fraction, take the following steps :
1. Multiply the whole number by the denominator
2. Add the numerator to the answer gotten in the previous step
3. divide the number gotten in the previous step by the denominator
3/2 x $12 = $18
A circle has a diameter that measures 14in. what is the area of the circle to the nearest tenth?
Answer:
153.9
Step-by-step explanation:
14/2=7 which is the radius which you square and it results to 49. multiply that times pi for 153.86 or 153.9 to the nearest tenth.
Answer:
153.9
Step-by-step explanation:
We know that the equation to find the area of a circle in [tex]\pi r^2\\[/tex]. So we divide the diameter by half and we plug in the radius.

From the top of a cliff 8 metres high,two boats are seen in a direction due West. Find the distance between the boats if their angles of depression from the top of a cliff are 45 degrees and 30 degrees. Find also the actual distance the further boat from the top of the cliff.
Answer:
Distance of first boat = 8 meter
Distance of second boat = 13.87 meter (Approx.)
Step-by-step explanation:
Given:
Height of cliff = 8 meter
Angle of depression respectively = 45° and 30°
Find:
Distance of boats
Computation:
Tanθ = Perpendicular / Base
Tan45 = 8 / Distance of first boat
1 = 8 / Distance of first boat
Distance of first boat = 8 meter
Tan30 = 8 / Distance of second boat
0.577 = 8 / Distance of second boat
Distance of second boat = 8 / 0.577
Distance of second boat = 13.8648
Distance of second boat = 13.87 meter (Approx.)
hello guys I am with another new question-- 5√6=what? who answers will get!!

Hope this helps!!! :)
What is the length of this rectangle?
Answer and Step-by-step explanation:
The answer is:
[tex]x^3 - 3[/tex]
When we multiply this length by the height ([tex]8x^{2}[/tex]), we get the area.
When a power/exponent (attached to a base/number) is having its' base being multiplied to another base with an exponent (and the bases are the same), the exponents will add together.

What is the supplement of ([dozen sixes] + 80)degrees?
28 degrees
22 degrees
82 degrees
188 degrees
Answer:
28°
Step-by-step explanation:
Supplementary angles sum to 180°
( dozen sixes) + 80
= 12 × 6 + 80
= 72 + 80
= 152°
supplement = 180° - 152° = 28°
GEOMETRY HELP ASAP !!!!
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
copy the above onto your computer for future reference
sin(g) = 420/427
tan(z) = 77/420
cos(z) = 420/427
sin(m) = 427/427
part (E) the sin of any right angle will be 1 :)
Answer:
Solution given:
Sin G=opposite/hypotenuse=420/427
TanZ=Opposite/adjacent=77/420
CosZ=adjacent/hypotenuse=420/427
Sin M=opposite/hypotenuse=427/427=1
What angle is this?

One day, the hours without daylight in a particular city was 17 3/4 hours. What was the number of hours of daylight? PLS help me ASAP!
Answer:
6 ¼ hours of Daylight
Step-by-step explanation:
a day = 24 hoursyou know that there was 17 ¾ hours of no day light 17 ¾ = 17.7524 - 17.75 = Daylight hoursdaylight hours = 6.25A silo for storing grain Is shaped like a cylinder with a cone on top the cylinder is 40 feet tall and has a radius of 20 feet the cone is 10 feet tall with the same radius approximately how many cubic feet of grain can fit in the is shaped like a cylinder with a cone on top the cylinder is 40 feet tall and has a radius of 20 feet the cone is 10 feet tall with the same radius approximately how many cubic feet of grain can fit in the
silo
Answer: 54,454 ft^3
The volume of the cylinder is about 50265.4 and the volume of the cone is 4188.7. If you add this together you get 54,454.1. Therefore, 54,454 ft^3 is the answer
Matti built a greenhouse in his backyard as shown below. A triangular prism with a rectangular base. The prism has a base of 7 feet by 15 feet. The height is 7 feet. The side lengths are 7.8 feet. How much cubic space is in Matti's greenhouse? 191.1 ft 367.5 ft 382.2 ft 735.0 ft
Answer:
Capacity of Matti's green house = 367.5 cubic feet
Step-by-step explanation:
Given:
Base Width and Length = 7 feet by 15 feet
Height of prism = 7 feet
Find:
Capacity of Matti's green house
Computation:
Capacity of Matti's green house = Volume of rectangular base[triangular prism]
Volume of rectangular base[triangular prism] = Area of triangular base x Height
Capacity of Matti's green house = [(1/2)(7)(7)][15]
Capacity of Matti's green house = [(1/2)(49)][15]
Capacity of Matti's green house = [(24.5)][15]
Capacity of Matti's green house = 367.5 cubic feet

help find value of x and Angle HIK
Answer:
4) x = 19
Part B = 37
Step-by-step explanation:
These 2 angles are equal to each other because they're vertical angles.
4x + 67 = 143
4x = 143 - 67
4x = 76
x = 19
m<HIK:
180 - 143 (because it's supplementary to m<GIK)

Answer:
Step-by-step explanation:
surface are of cuboid=2(lb+bh+hl)
=2(14*12+12*6+6*14)
=2(168+72+84)
=2*324
=648 in.^2
Answer:
648 inches
Step-by-step explanation:
First, you do 14 times 12 times 2 and get 336.
Next, you do 14 times 6 times 2 and get 168.
Then you do 6 times 12 times 2 and get 144.
Now add 336, 168, and 144 together to get 648.

R = {8, 27, 64}
The perimeter fence of a certain lot for Ipil-Ipil seedlings is 60 meters with the length of 10 meters. What is the area of the lot?
Answer: 200 m²
Step-by-step explanation:
The perimeter is calculated by the formula:
= (2 * length) + (2 * width)
We have the perimeter so we can find the width:
60 = (2 * 10) + (2 * w)
60 = 20 + 2w
2w = 60 - 20
w = 40 / 2
w = 20 meters
Area of a rectangle can be used because this fits the characteristics of a rectangle:
= Length * Width
= 10 * 20
= 200 m²
