Step-by-step explanation:
Hope this helped can I have brainliest please
The probability that she takes either a hard center or a soft center is, 5/6
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
A box of chocolates contains 4 hard centers, 6 soft centers and 2 plain chocolates.
Hence, We get;
Number of chocolates = 4 + 6 + 2 = 12
And, Number of a hard center or a soft center chocolates = 4 + 6 = 10
Thus, The probability that she takes either a hard center or a soft center is,
⇒ 10 / 12
⇒ 5/6
Hence, The probability that she takes either a hard center or a soft center is, 5/6

Travelers who fail to cancel their hotel reservations when they have no intention of showing up are commonly referred to as no-shows. In anticipation of no-shows and late cancellations, most hotels overbook(i.e., accept reservations for more rooms than the number of rooms in their inventory). The Journal of Travel Research(Spring 1985) reported that six major hotels in the Seattle area had a no-show rate of10%. Let X equal the number of no-shows among the four travelers who have made hotel reservations in this study.
a) What is the probability that at least two of the four selected will turn to be no-shows?
b) What is the most likely value for X?
Answer:
a) 0.0523 = 5.23% probability that at least two of the four selected will turn to be no-shows.
b) 0 is the most likely value for X.
Step-by-step explanation:
For each traveler who made a reservation, there are only two possible outcomes. Either they show up, or they do not. The probability of a traveler showing up is independent of other travelers. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
No-show rate of 10%.
This means that [tex]p = 0.1[/tex]
Four travelers who have made hotel reservations in this study.
This means that [tex]n = 4[/tex]
a) What is the probability that at least two of the four selected will turn to be no-shows?
This is [tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.1)^{2}.(0.9)^{2} = 0.0486[/tex]
[tex]P(X = 3) = C_{4,3}.(0.1)^{3}.(0.9)^{1} = 0.0036[/tex]
[tex]P(X = 4) = C_{4,4}.(0.1)^{4}.(0.9)^{0} = 0.0001[/tex]
[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.0486 + 0.0036 + 0.0001 = 0.0523[/tex]
0.0523 = 5.23% probability that at least two of the four selected will turn to be no-shows.
b) What is the most likely value for X?
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.1)^{0}.(0.9)^{4} = 0.6561[/tex]
[tex]P(X = 1) = C_{4,1}.(0.1)^{1}.(0.9)^{3} = 0.2916[/tex]
[tex]P(X = 2) = C_{4,2}.(0.1)^{2}.(0.9)^{2} = 0.0486[/tex]
[tex]P(X = 3) = C_{4,3}.(0.1)^{3}.(0.9)^{1} = 0.0036[/tex]
[tex]P(X = 4) = C_{4,4}.(0.1)^{4}.(0.9)^{0} = 0.0001[/tex]
X = 0 has the highest probability, which means that 0 is the most likely value for X.

There is a spinner with 10 equal areas, numbered 1 through 10. If the spinner is spun
one time, what is the probability that the result is a multiple of 5 or a multiple of 2?
Answer:
3/5
Step-by-step explanation:
In the numbers 1 thru 10, there are 5 multiples of 2 (2, 4, 6, 8, 10) and 2 multiples of 5 (5, 10). Since you cannot count 10 twice, there are 6 possibilities (2, 4, 5, 6, 8, 10)
So the probability of spinning a multiple of 2 or 5 is 6/10 = 3/5
Answer:2/10 probabilty for the multiple of 5 and a 5/10 or 50% chance that it will be a multiple of 2
Step-by-step explanation: 10 areas, there are 2 multiples of 5,( 5 and 10 )and there is a 2/10 chance of landing on landing 5 or 10 because there are 2 multiples of 5. There are also 5 multiples of 2, (2, 4, 6, 8, 10) 5/10 chance because there are 5 multiples out of 2

Precio sin IVA= $66,67
The circle below is centered at the point (1, 2) and has a radius of length 3.
What is its equation?
Answer:
[tex](x - 1) {}^{2} + (y - 2) {}^{2} = 9[/tex]
Step-by-step explanation:
The general circle equation is
[tex](x - h) {}^{2} + (y - k) {}^{2} = r {}^{2} [/tex]
where r is the radius.
Since we know all the information just plug it in the equation above.
[tex](x - 1) { }^{2} + (y - 2) {}^{2} = {3}^{2} [/tex]
Simplify 3 squared.
[tex](x - 1) {}^{2} + (y - 2) {}^{2} = 9[/tex]
Although traffic fatalities have been decreasing for years, this decrease has not been experienced equally in all segments of the population. In fact, although the overall rate of traffic fatalities has been decreasing, the rate has declined the most for those with more education and has actually gone up for those without high school degrees. A recent study shows that among those over 25, as education level increased from less than high school, to high school grad, to some college, to college grad, the rate of motor vehicle crash deaths decreased.
1) What are the explanatory and response variables? Drag each variable to the appropriate column
1. Rate of motor vehicle crash deaths
2. Level of education
A) Response Variable
B) Explanatory Variable
2) Those with less education tend to drive cars that are older, have poorer crash test ratings, and have fewer safety features such as side airbags. Are the variables age of car, crash test rating, and presence of safety features explanatory variables, response variables, or lurking variables?
A) They are all explanatory variables since they are all characteristics of a car.
B) They are lurking variables as they are neither the primary explanatory nor response variables
C) They are all response variables since they can determine how much damage a car will receive in a motor vehicle crash.
D) None of the choices are correct education level good.
3) Is the association between traffic fatalities reason to think that a higher level of education actually causes an individual to be a safe driver? None of the choices are correct
A) Without an experiment, no causal relationship can be made.
B) There is a causal relationship because the study shows that the level of education has an impact on traffic fatalities are associated.
C) There is a causal relationship because level of education and motor vehicles.
D) None of the choices are correct.
Answer:
1.
The explanatory variable is the level of education.
response variable is Rate of motor vehicle crash deaths
2. b
3. A) Without an experiment, no causal relationship can be made.
Step-by-step explanation:
1.
The explanatory variable is the level of education.
The explanatory variable tells us that more education among people over 25 years, brings about a reduction in motor deaths.
The response variable is the rate of motor vehicle deaths.
This variable actually responds to the changes in the explanatory variable. The rate of motor vehicle deaths could increase or decrease based on the level of education.
2.
They are lurking variables. option B
These variables are not known primarily as explanatory variables here in this relationship but they have the ability to affect the result of the study.
3. We have to carry out an experiment first in order to carry out a causal relationship.

Palindrome numbers are numbers that read the same foward or backward. Here are some palindrome numbers: 11, 121, 75257, and 1234321. The smallest three digit palindrome is 101. How many palindrome numbers are there between 10 to 1000?
Answer:
99.
Step-by-step explanation:
A palindrome number is one that can be read in the same way both from the front and from the back. A clear example is the number 242, which starts and ends in the same way from the front or back.
Between 10 and 100, there are 9 palindromes, from 11 to 99. In turn, between 100 and 200, 200 and 300 and so on, each hundred has within it 10 palindromes (101, 111, 121, 131, 141 , 151, 161, 171, 181 and 191, for example).
Therefore, considering the 9 hundreds between 100 and 1000, there will be 90 palindromes, which added to the 9 between 10 and 100 give a total of 99 palindromes.
What is the area of the segment?
Answer:
The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin(θ) 2 × r2 (when θ is in radians) Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)
