Answer:
Probability of getting a green ball is more than that of getting a white ball.
Step-by-step explanation:
There are in all (5+3= 8) outcomes of the experiment. There are 5 outcomes in favour of the event of getting a green ball as there are 5 identical green balls in the bag.
Therefore, P(a green ball) = 5/8
In the same way,P(a white ball) = 3/8
5/8 > 3/8Thus, clearly the probability of getting a green ball is more than that of getting a white ball.
Find the distance points
Answer:
8/5x
Step-by-step explanation:
it's (-4,-4) and (1,4) so you subtract the y's getting 8. then you subtract the x's getting 5. y/x is the rule so you would get 8/5 or 8/5x as the slope/distance between points.
Suppose you are a lawyer representing a Hispanic individual in a criminal trial. Twelve jurors are randomly selected by the state from a population that you know to be 40% Hispanic.
a. How many jurors would you expect to be Hispanic?
b. The select process produces a jury with 3 Hispanic individuals What proportion of the jury is Hispanic? (Enter your answer as a decimal, rounded to four decimal places)
c. Use the binomial distribution and find the probability that 3 or fewer jurors would be Hispanic.
Using the binomial distribution, it is found that the desired values are given as follows:
a) 4.8 jurors.
b) The proportion is of 0.25.
c) 0.2254 = 22.54% probability.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, we have that:
Twelve jurors are randomly selected by the state, hence n = 12.The state is known to be 40% Hispanic, hence p = 0.4.Item a:
The expected value of the binomial distribution is given by:
E(X) = np
Hence:
E(X) = 12 x 0.4 = 4.8 jurors.
Item b:
The proportion of 3 out of 12 is 3/12 = 1/4 = 0.25.
Item c:
The probability is given by:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{12,0}.(0.4)^{0}.(0.6)^{12} = 0.0022[/tex]
[tex]P(X = 1) = C_{12,1}.(0.4)^{1}.(0.6)^{11} = 0.0174[/tex]
[tex]P(X = 2) = C_{12,2}.(0.4)^{2}.(0.6)^{10} = 0.0639[/tex]
[tex]P(X = 3) = C_{12,3}.(0.4)^{3}.(0.6)^{9} = 0.1419[/tex]
Then:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0022 + 0.0174 + 0.0639 + 0.1419 = 0.2254[/tex]

Which of the following is a polygon?
A shape can only be classified as a polygon if:
(1) There must be no curves in the shape.(2) The shape is not opened. It has to be closed.(3) The sides of the shape must not intersect each other.Option A
We can see that the figure is opened. Therefore, the shape is not a polygon. According to (2), to classify a shape, a polygon, the shape must not be opened.
Therefore, this shape is not a polygon.
Option B
This shape is a polygon because it has no curves, it is not opened, and the sides of the shape are not forming an intersection.
Therefore, this shape is a polygon.
Option C
This figure has a side length intersecting another side length. Therefore, this figure is not a polygon. According to (3), to classify a shape, a polygon, the sides of the shape must not intersect each other.
Therefore, this shape is not a polygon.
Option D
This figure is not a polygon because a side length of the figure is curved. According to (1), To classify a shape, a polygon, there must be no curves in the shape.
Therefore, this shape is not a polygon.
Hence, Option B is correct.
Daniel’s spinner is divided into 8 equal sections. A spinner divided into 8 equal sections labeled gray, green, red, purple, gray, green, yellow, blue. He plans to spin it 80 times. Which equation predicts the number of times that he could spin green? P (green) = StartFraction 1 over 8 EndFraction (80) P (green) = StartFraction 2 over 8 EndFraction (80) P (green) = StartFraction 3 over 8 EndFraction (80) P (green) = one-half (80)
We expect to get the color green 10 times out of the 80.
How many times we expect to get the color green?
The spinner is divided into 8 equal colors, so we can assume that each one of the 8 colors has the same probability of being spun.
This means that if we spin the spinner, the probability of getting the color green is p = 1/8.
So, in 80 tries, we will expect to get the color green a total of:
N = (1/8)*80 = 10
We expect to get the color green 10 times out of the 80.

Answer:
The correct answer is P(green)=2/8 (80)
Step-by-step explanation:
Daniel’s spinner is divided into 8 equal sections.
A spinner divided into 8 equal sections labeled gray, green, red, purple, gray, green, yellow, blue.
As you can see there are 2 greens so it would be 2/8 since there are 8 pieces and 2 greens out of those 8.

What is the surface area for each part of the figure?
The surface area of the pyramid is (96, 60, 48) square feet.
The surface area of the square prism is (480, 552) square feet.
The surface area of the cube is (180, 216) square feet.
The total surface area is (816, 700, 688, 756) square feet.
The surface area of the pyramid is 96 ft²
The surface area of the square base prism is 552 ft²
The surface area of the cube is 216 ft²
The total surface area is 756 ft²
How to find surface area?The surface area of the pyramid = A + 1/2 ps
where
A = base areap = perimeters = slant heightTherefore,
A = 6² = 36 ft²
p = 4(6) = 24 ft
s = √3² + 4² = √9 + 16 = √25 = 5 ft
Hence,
The surface area of the pyramid = 36 + 1 / 2 × 24 × 5 = 96 ft²
The surface area of the square base prism = 2a² + 4ah
where
a = side of the square baseh = heightTherefore,
The surface area of the square base prism = 2(6)² + 4(6)(20) = 72 + 480 = 552 ft²
The surface area of the cube = 6l² = 6 × 6² = 6 × 36 = 216 ft²

Answer:
56
Step-by-step explanation:
We know that every triangle no matter will equal 180 degrees. So we will make an algebreic expression.
2x+8+60=180
When doing algebreic expression we want to simply as much as possible to find our answer. First we will do 60-180. Since the expression is adding 60 we want to do the opposite and subtract is by 60 on both sides. SO now we have 2x+8=120. We do the same thing with 8. Subtract it on both sides since its adding in the expression. Now we have 2x=112. FInally, we will divide by two on both sides since its multiplying on the other side of the equation. So now we are left with x=56.
