Of the first 52 contestants, exactly 12 contestants win the game. How does the actual number of winners compare to the expected number of winners? What needs to happen for the experimental probability to approach the theoretical probability? Explain
pls help me
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.

Find area of the composite figure..
Answer:
627square inches
Step-by-step explanation:
Area of the composite figure.. = area of triangle + area of parallelogram
Since the triangle is an equilateral triangle;
Area of the triangle = r²sintheta
Area of the triangle = 18²sin60
Area of the triangle = 324sin60
Area of the triangle = 324(0.8860)
Area of the triangle = 280.584 square in
Area of the triangle = 281 square inches
Area of parallelogram = absintheta
Area of parallelogram = 20(20)sin60
Area of parallelogram = 400(0.8660)
Area of parallelogram = 346.4square inches
Area of parallelogram = 346 square inches
Area of the figure = 346 + 281
Area of the figure = 627square inches

7 mi
2 mi
351.9 cubic mi.
Ob
117.3 cubic mi.
Ос
29.3 cubic mi.
Od
7.3 cubic mi.
Answer:
c. 29.3 cubic mi
Step-by-step explanation:
Applying,
V = πr²h/3.............. Equation 1
Where V = volume of the cone, r = radius of the circular base, h = height of the cone, π = pie
From the diagram,
Given: h = 7 mi, r = 2 mi
Constant: π = 3.14
Substitute these values into equation 1
V = 3.14(7×2²)/3
V = 29.3 cubic mi
Hence the right answer is c. 29.3 cubic mi
Two square pyramids are similar.
The sides of the bases are 4 cm and
12 cm. The height of the smaller
pyramid is 6 cm. Find the height of
the larger pyramid.
Answer:
18 cm
Step-by-step explanation:
Since the pyramids are similar then the ratio of corresponding sides are equal, that is
12 ÷ 4 = 3
Then the height of the larger pyramid is 3 times the height of the smaller.
height of larger pyramid = 3 × 6 = 18 cm

The number of patients treated at Dr. Frank's dentist office each day was recorded for nine days: 18,
19, 19, 4, 14, 8, 22, 3, 1. Using the given data, find the mean for this sample.
A. 12
B.19
C. 29
D. 14
Answer: 12
Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

if one of the factor of x²+x-20 is (x+5) find other factor
Answer:
Step-by-step explanation:
x^2+x-20
=x^2-(5-4)x-20
=x^2-5x+4x-20
=x(x-5)+4(x-5)
=(x-5)(x+4)
therefore the other factor is (x+4)
Answer:
(x - 4)
Step-by-step explanation:
METHOD 1 (Long Division Method):-
[See the attachment for full solution of Method 1]
One factor of x² + x - 20 is already given. To find the other factor , divide the polynomial with the factor and the quotient you'll get after dividing will be the second factor of the polynomial.
METHOD 2 (Factorising) :-
Factorise x² + x - 20.
Split the middle terms.[tex]=> x^2 + 5x - 4x - 20[/tex]
Take 'x' common from first two terms and take '-4' common from last two terms.[tex]=> x(x + 5) - 4(x + 5)[/tex]
Take '(x+5)' whole common from the expression.[tex]=> (x + 5)(x - 4)[/tex]
(x + 5) & (x - 4) are the factors of x² + x - 20.

Find the length of arc XW. Round your answer to the nearest hundredth.
Answer:
15.08 m
Step-by-step explanation:
The angle XZW :
XZW + 108° = 180°
XZW = 180° - 108°
XZW = 72°
Length of an arc = θ / 360 * πd
d = diameter = XV = 24
Length of arc XW = (72/360) * π * 24
Length of arc XW = 15.0796
Length of XW = 15.08 m
Answer:
15.08

Se va a colocar una escalera que mide 5 metros (m) de longitud sobre una pared. El fabricante de la escalera recomienda que, por seguridad, el ángulo que forme la escalera con el piso sea de 78°, ¿Cuál será la distancia sobre el piso del pie de la escalera a la pared?
Answer:
4.9 m
Step-by-step explanation:
Resolvemos la pregunta anterior usando la función trigonométrica de seno
sin θ = Opuesto / Hipotenusa
θ = 78 °
Hipotenusa = Longitud de la escalera = 5 m
Opuesto = Distancia sobre el suelo = x
sin 78 = x / 5m
Multiplicar cruzada
x = sin 78 × 5 m
x = 4.8907380037m
Aproximadamente
= 4.9 m
Jack tool out a 6-year loan for $25,000 to purchase a boat at a 4.5% interest rate. If the interest is compounded monthly, what will he have paid total over the course of the loan?
Answer:
A = $32,732.58
A = P + I where
P (principal) = $25,000.00
I (interest) = $7,732.58
Step-by-step explanation:
Given data
Time= 6 years
Principal= $25,000
Rate= 4.5%
First, convert R as a percent to r as a decimal
r = R/100
r = 4.5/100
r = 0.045 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 25,000.00(1 + 0.045/12)^(12)(6)
A = 25,000.00(1 + 0.00375)^(72)
A = $32,732.58
Determine the value of x.
A) 12
B) 2√3
C) 12√3
D) 6√3
Answer:
D
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° = [tex]\sqrt{3}[/tex] , then
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{6}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by 6 )
x = 6[tex]\sqrt{3}[/tex] → D

Write True or False. You can use the measures of the angles formed by two lines and a transversal to determine whether the two lines are parallel.
Answer:
I think that the answer is true (explanation might not be 100% accurate)
Step-by-step explanation:
Given that for 2 lines to be parallel, they have to never intersect at any point, meaning they both have to be straight and "facing" the same way. If either line has a tilt/angle of any sort, then they are not parallel.

Answer: Por ejemplo, un televisor podría costarle originalmente $ 5000. Determine el porcentaje de descuento: en nuestra tienda de ejemplo, todo tiene un 75% de descuento. La suma que queda en su bolsillo, sus ahorros, es simplemente estos dos valores multiplicados entre sí: 75% * $ 5000 = 0,75 * $ 5000 = $ 3750.
What is the slope (rate of change)
Someone please help me with this im not good with graphs.
Answer:
1
Step-by-step explanation:
1. To get the slope, you need to divide the rise by the run.
2. Pick two points each on the X-axis and pick corresponding points on the Y axis and then name them y2, x2 and y1, x1.
3. The rise will be y2-y1
4. The run will be x2-x1
5. Therefore, the slope is rise/run = (y2-y1)/(x2-x1)
In this case, let's take 2 on the X axis as x2 and the corresponding point on the Y axis as y2 which in this case happens to also be 2.
Now, let's take 1 on the X axis as x1 and the corresponding point on the Y axis as y1 which is also 1.
now using the formula (y2-y1)/(x2-x1), we get: slope = (2-1)/(2-1) = 1
A baker is selling pies his first customer buys 1/2 of all the pies plus 1/2 of a pie. His second customer then buys 1/2 of the pies plus 1/2 of a pie the last customer buys 1/2 of the pies plus 1/2 pie. he has no more pies. how many did he start with?
Answer:
7 pies
Step-by-step explanation:
The first customer buys half of the pies (3-1/2) plus 1/2 of a pie (technically 4 pies in total) -----> there are 3 pies left.
The second customer buys half of the pies leftover (1-1/2) plus another 1/2 (technically 2 pies in total) -----> this leaves 1 pie.
The last customer buys half of the pies leftover (1/2) plus another 1/2 (technically 1 pie in total) -----> this leaves 0 pies.
