3. There are 500 students in Pures College, 150 students are enrolled in Statistics course and 80 students are enrolled in a Maths course. There are 30 students who are taking both Statistics and Maths courses. (6 marks) Required: If a student is chosen at random a. What is the probability that the student is taking Statistics b. What is the probability that the student is taking Maths given that the student is also taking Statistics c. What is the probability that the student is taking Statistics given that the student is also taking Maths

Answers

Answer 1

Answer:

a. 0.3

b. 0.2

c.0.375

Explanation:

A.  is asking for the number of students taking stats divided by the total Students. So in this case 150/500 which equals 0.3

B. This is asking for the number of students taking both stats and math divided by the number of students that are taking stats. So 30/150 which equals 0.2

C. This is asking for the number of students taking both stats and math divided by the number of students that are taking math. So 30/80 which equals 0.375

Answer 2

The probabilities for the different given scenarios are;

A) 0.3

B) 0.2

C) 0.375

We are given;

Total number of students enrolled in pures college = 500Number of students taking statistics = 150Number of students taking Maths = 80Number of students taking both maths and stats =30

A) Probability that the student is taking statistics = 150/500 = 0.3

B) The probability that the student is taking Maths given that the student is also taking Statistics = 30/150 = 0.2

C) The probability that the student is taking Statistics given that the student is also taking Maths = 30/80 = 0.375

sorry if this is long

Explanation:

literally this whole week was either boring or upsetting. so basically in my math class, my math teacher left us for like 3 days of the week for whatever reason and she is literally the best. she makes me calmer and it stressed me out that she wasn’t there (its weird i know) but im not sure if she’s back yet or not. now i have to make a poster, do an essay, 3 part test (like 5 - 7 questions each) and probably something else that my next class will assign. and there’s a whole bunch of death. i’m stressed. and no i don’t think that anything i learned this week i will use in the future. there’s nothing i can think of that i would need it for. maybe a skill based on it, i’m not sure but yeah. i didn’t really answer towards the question but uh thanks for the points and letting me rant.

Percent of change
Find the Percent of decrease for the following problems:
1. Chad played three hours of Pokémon Go per day during the summer. Since
school began, he is only allowed to play one hour per day.
2. Karen has 7 Eevees in her Pokémon stash. She transferred some in to the
Professor and now only has 2 Eevees.
3. It takes 200 coins to get a bag upgrade in Pokémon Go. The creators
decided to throw a sale on bag upgrades. For one day only, anybody can
upgrade their bag for 125 coins.

Answers

Answer:

1. 66.6%

2. 71.42%

3. 37.5

Explanation:

percent of decrease= (new - old) /old

1. Chad's play time decreased by 66.66%.

2.  Karen's number of Eevees decreased by 71.42%.

3. The price of a bag upgrade decreased by 37.5%.

How do we calculate?

1.

Chad's original play time was 3 hours per day. His new play time is 1 hour per day. The percent decrease is:

(Original - New) / Original * 100%

= (3 - 1) / 3 * 100%

= 2 / 3 * 100%

= 66.66%

2.

Karen's original number of Eevees was 7. Her new number of Eevees is 2. The percent decrease is:

(Original - New) / Original * 100%

= (7 - 2) / 7 * 100%

= 5 / 7 * 100%

= 71.42%

3.

The original price of a bag upgrade is 200 coins. The sale price is 125 coins. The percent decrease is:

(Original - Sale) / Original * 100%

= (200 - 125) / 200 * 100%

= 75 / 200 * 100%

= 37.5%

this wont help but both because if your really behind on school then yes it will or if they class is doing a test or a big assignment it can impact your grades but on the other hand a couple days off from school is needed from the stress the teachers put us through. there is not point in making us so stressed to the point that we are behind so if anything it all depends on the teachers response to you not going to school for a couple of days. but I my opinion the teachers could do a bit better. are parents and gardeners pay them to give us a good education but all they give us is bad stress and depression as well as bullies and bad teachers theres no way in the world that us kids deserve that. so if anything it's the teachers fault if we are behind or if we aren't

Write the equation of a parabola that has vertex (2.5, 2.75) and passes throught the point (1,5).

Answers

Answer:

y = (x - 2.5)^2 + 2.75

Explanation:

y = a(x - h)^2 + k - Vertex form

y = a(x - 2.5)^2 + 2.75 - Replacing h with 2.5 and k with 2.75

5 = a(1 - 2.5)^2 + 2.75 - Replacing x with 1 and y with 5

5 = 2.25a + 2.75 - Doing (1 - 2.5)^2 = 2.25 times a = 2.25a

2.25 = 2.25a - Subtracting 2.75 on both sides

a = 1

y = 1(x - 2.5)^2 + 2.75 - Replacing a with 1

So the equation of a parabola is y = (x - 2.5)^2 + 2.75

The vertex of a parabola is the minimum or the maximum point of the parabola

The equation of the parabola is [tex]\mathbf{y = a(x -1)^2 + 5}[/tex]

The given parameters are:

[tex]\mathbf{(x,y) = (2.5,2.75)}[/tex] --- point

[tex]\mathbf{(h,k) = (1,5)}[/tex] -- vertex

A parabola is represented as:

[tex]\mathbf{y = a(x -h)^2 + k}[/tex]

Substitute the given values in the above formula

[tex]\mathbf{2.75 = a(2.5 -1)^2 + 5}[/tex]

[tex]\mathbf{2.75 = a(1.5)^2 + 5}[/tex]

[tex]\mathbf{2.75 = 2.25a + 5}[/tex]

Subtract 5 from both sides

[tex]\mathbf{2.25a =-2.25}[/tex]

Divide both sides by 2.25

[tex]\mathbf{a =-1}[/tex]

Substitute [tex]\mathbf{a =-1}[/tex] and [tex]\mathbf{(h,k) = (1,5)}[/tex] in [tex]\mathbf{y = a(x -h)^2 + k}[/tex]

[tex]\mathbf{y = a(x -1)^2 + 5}[/tex]

Hence, the equation of the parabola is [tex]\mathbf{y = a(x -1)^2 + 5}[/tex]
