Answer:
c = 12
Step-by-step explanation:
a, b, and c are all vectors that have the same direction.
a + b = c
The magnitude of a = 6 and the magnitude of b = 8.
Find the magnitude of c.
Answer:
14 = c
Step-by-step explanation:
it is just like u said;
a + b = c
6 + 8 = c = 14
(it could also be 8-6 = c = 2)
Michael is writing an article for the school newspaper. He wants to know which subject (math, reading, science, history, or physical education)
is most liked. He is trying to decide who to survey.
Which population sample does NOT produce a biased result?
A. He asks the school’s teachers
B. He asks his friends after school
C. He asks the students in his math class
D. He asks students he meets in the hallways
E. He asks every fifth student arriving at school
Answer: E is the answer
Step-by-step explanation:
The population sample that does not produce a biased result is when he asks every fifth student arriving at school. The correct option is E.
What is a survey?Surveys can be used to determine how representative each person's opinions and experiences are.
When conducted properly, surveys offer precise data about people's beliefs and actions that can be utilized to inform significant decisions.
A huge population's characteristics can be described through surveys. No other research methodology can offer such a wide range of capabilities.
This guarantees a more accurate sample to collect focused results from which to draw conclusions and make significant judgments.
Survey bias is when a question is worded or presented in a way that encourages individuals to select one response over another.
The same holds true if your queries are challenging for customers to comprehend and honestly answer.
As, when he asks every fifth student arriving at school, it can lead to an unbiased result.
Thus, the correct option is E.

What is the probability of spinning a blue or yellow?
Answer:
2/4 or 1/2
Step-by-step explanation:
The solution is, 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
There are four (4) colors to choose from.
The number of sample space is equal to 4.
With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4.
Similarly, the probability of landing on yellow on the second spin is 1/4.
so, we get,
P = (1/4)(1/4)
P = 1/16
Answer: 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin

Question 8 of 25
If a sample mean is 96, which of the following is most likely the range of
possible values that best describes an estimate for the population mean?
O A. (76, 108)
O B. (82, 114)
O C. (78, 110)
O D. (80, 112)
The correct range is (80, 112).
The correct option is (D).
What is mean?Mean is also said to be arithmetic mean. The meaning of mean is to evaluate the average. It is defined as the average of the given numbers.
As per the given data:
We are given the mean of the sample.
The mean of the sample = 96
In each option, a range is given.
We have to find out which is the correct range for the given mean.
For a range (a, b) the mean is given by:
mean = (a + b)/2
By using the above definition and checking all the options:
For (76, 108)
mean = (76 + 108)/2 = 92, Not the correct range
For (82, 114)
mean = (82 + 114)/2 = 98, Not the correct range
For (78, 110)
mean = (78 + 110)/2 = 94, Not the correct range
For (80, 112)
mean = (80 + 112)/2 = 96, The correct range
The correct range is (80, 112).
Hence, the correct range is (80, 112).

Events M and N have probabilities such that P(M) = 0.4, P(N) = 0.28, P(M ∪ N) = 0.56, and P(M ∩ N) = 0.12. Are events M and event N independent?
A.
Yes, because P(M) + P(N) = P(M ∪ N).
B.
No, because P(M) ∙ P(N) ≠ P(M ∩ N).
C.
Yes, because P(M) ∙ P(N) ≠ P(M ∪ N).
D.
No, because P(M) - P(N) = P(M ∩ N).
i need this asap
Answer: The answer is B.
Step-by-step explanation:
This is using the independent probability
Are events M and event N independent. No, because P(M)·P(N) ≠ P(M ∩ N).
What do you mean by independent events?
A and B are said to be independent events if the probability of an event A occurring is unaffected by the occurrence of another event B whereas dependent events influence the probability of other events Independent events can have common outcomes.
If two events A and B are independent of each other, then A and B have equal probability of occurring as
P(A∩B) = P(A) · P(B)
Event M and N have probabilities such that P(M) = 0.4, P(N) = 0.28 , P(M∪N) = 0.56 and P(M∩N) = 0.12
P(M)·P(N) = 0.4 × 0.28 = 0.112
and P(M∩N) = 0.12 (Given)
So, P(M∩N) ≠ P(M)·P(N)
This shows that both the events are not independent events.
Therefore, Event M and N are not independent event.
