PLEASE HELP WITH STEPS!!!!!!! ANSWER IN SCIENTIFIC NOTATION I WILL GIVE BRIANLIEST

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.

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.

351cm³

step by step explanation:

Volume of the prism:

=[1/2×(a+b)×h]×l

=[1/2×(5+8)×6]×9

=(1/2×13×6)×9

=(6.5×6)×9

Answer:

n = 24

p(a) = 10/24

p(b) = 15/24

[ p(a) + p(b) - [p(a) ×p(b)] ] -1 = answer

[ 35/24 - 6/24 ] -1 = 39/24 - 24/24 = 5/24

The guy up there did good. I used 100pts to ask a question not 50

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.

Chanel found a used bookstore that sells pre-owned DVDs and CDs. DVDs cost $9 each, and CDs cost $6 each. Chanel can spend no more than $108 Write an inequality that represents this

Answer:

Answer:

radius=3

Step-by-step explanation:

volumes of a cone = 1/3πr²h

12π = 1/3× π × r² × 4

37.7 = 12.6r²/3

cross multiply

37.7×3=12.6r²

113.1=12.6r²

make r² subject of the formula

r²=113.1÷12.6

r²=8.976

r=√8.976

r=2.996

r=3.0 (to the nearest tenth)

The correct range is (80, 112).

The correct option is (D).

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).

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.

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

→ Base = 15 and 10

→ Height = 12

→ Area of trapezoid

→ Area of Trapezoid = (a + b)/2 × h

= (15 + 10)/2 × 12

= 150 ft²

∴ The area of Trapezoid is 150 ft²
