I NEED HELP ASAP ILL GIVE BRAINLIEST AND 30 points

The question you are asking is not that really hard. In fact it is really easy.

I will give you my examples for some question.

1. (example) The probability of the two heads shown will be more than the two tails shown\

2. Since I hit 17 / 100 (17%) for the two heads and I hit 11 / 100 (11%) for the two tails, then my (example) theory was correct since I stated that there will be more probability showing two heads than on two tails.

Basically at questions 3 & 4 (and also 5 & 6), it is the same as questions 1 & 2.

In question 1, 3, and 5, you need to state what YOU think will happen before doing the 100 coin flip.

Then in question 2, 4, and 6, you need to sate IF YOUR THEORY WAS CORRECT OR WRONG using the results you have. It does not matter if you are wrong.

I will give you my example for 1 and 2 question.

1. (example) The probability of the two heads shown will be more than the two tails shown

2. Since I hit 17 / 100 (17%) for the two heads and I hit 11 / 100 (11%) for the two tails, then my (example) theory was correct since I stated that there will be more probability showing two heads than on two tails.

Basically at questions 3 & 4 (and also 5 & 6), it is the same as questions 1 & 2.

For question number 7, the answer is because my theory is just a guess before the outcome.

You can vote how good my answer is, I just hoped I helped you clarify your misunderstandings.

Of all the people applying for a certain job, 80% are qualified and 20% are not. The personnel manager claims that she approve

motikmotik

Answer:

69.23% probability that a person is not qualified if he or she was not approved by the manager.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes:

In this problem, we have these following probabilities:

80% probability that a person is qualified

20% probability that a person is not qualified.

90% probability that a qualified person is approved.

10% probability that a qualified person is not approved.

10% probability that an unqualified person is approved.

90% probability that an unqualified person is not approved.

Find the probability that a person is not qualified if he or she was not approved by the manager.

Desired outcomes

Unqualified and not approved.

20% are not qualified. Of those, 90% were not approved. So

$0.9*0.2 = 0.18$

Total outcomes:

Qualified and not approved or unqualified and not approved.

80% are qualified. Of those, 10% were not approved

20% are not qualified. Of those, 90% were not approved. So

$0.8*0.1 + 0.9*0.2 = 0.26$

Probability

$P = \frac{0.18}{0.26} = 0.6923$

69.23% probability that a person is not qualified if he or she was not approved by the manager.

PLEASE HELP ILL MARK BRAILIEST!!!<br><br><br> P.S please show how you figured it out

Arturiano [62]

Answer:

I think that the answer is either B or C

Step-by-step explanation:

I concluded to this answer simply by looking at where the lines were placed.

Remember that if a line is not touching, but next to another line, they are parallel to each other? Well, that doesn't change here. since, {m angle 1} and {m angle 2} added together equal 180, I would believe that the answer is C, but I may be wrong.

Well, I hope that helps :)

Flour costs $0.80 per pound and sugar costs $0.50 per pound. An order of flour and sugar weighs 15 pounds and costs $9.00. Make

LenaWriter [7]

Answer: $x+y=15$

$0.80x+0.50y=9$

Step-by-step explanation:

Let x be the amount of flour and y be the amount of sugar ordered.

Since, the order of flour and sugar weighs 15 pounds.

Therefore, $x+y=15$

Also, Flour costs $0.80 per pound and sugar costs $0.50 per pound.

The cost of ordered flour=$0.80x

The cost of ordered sugar=$0.50y

Now, the total cost of the order= $0.80x+0.50y=9$

Hence, for the given situation the system of equations is:-

$x+y=15$

$0.80x+0.50y=9$

En un colegio de 900 alumnos, 350 profundizan sus estudios en Matemáticas, 220 en Ingles y 110 en ambas áreas. El número de alum

zalisa [80]

Answer:

the number of students who do not delve in any of the 2 areas is 220

Step-by-step explanation:

The computation of the number of students who do not delve in any of the 2 areas is shown below:

= Total students - maths students - english students - both subject students

= 900 - 350 - 220 - 110

= 220

Hence, the number of students who do not delve in any of the 2 areas is 220
