You have a bag of 15 marbles. 8 are red. 5 are blue. 2 are green. You asked 15 people to pull a random marble and replace it. Th

e outcome was that 10 got red, 4 got blue and 1 got green. Joe thinks if 15 more people try 8 will pull red. Jill thinks if 15 more people try 10 will pull red. Choose the most accurate statement.
a
Joe is right because the theoretical probability is better.
b
Jill is right because the experimental probability is better.
c
We don't know what will happen, but both Joe and Jane are making good, educated assumptions.
d
We don't know what will happen because anything is possible and there is not point in calculating probabilities. Whatever happens, happens.
e
6 people will pull red to average out to 8. The long term average must match the theoretical probability.

Answer:

C.

Step-by-step explanation:

We have 2 probabilities: Theoretical probability and Experimental probability.

We cant know what will happen as it's just probability but both joe and Jill are making educated guesses based on probabilities, just different kinds.

A father is 32 years older than his son. In four years,
sergiy2304 [10]

Answer:

  • father: 36
  • son: 4

Step-by-step explanation:

Let s represent the son's age now. Then s+32 is the father's age. In 4 years, we have ...

  5(s+4) = (s+32)+4

  5s +20 = s +36 . . . . . eliminate parentheses

  4s = 16 . . . . . . . . . . . . subtract s+20

  s = 4

The son is now 4 years old; the father, 36.

_____

<em>Alternate solution</em>

In 4 years, the ratio of ages is ...

  father : son = 5 : 1

The difference of their ages at that time is 5-1 = 4 "ratio units". Since the difference in ages is 32 years, each ratio unit must stand for 32/4 = 8 years. That is, the future age ratio is ...

  father : son = 40 : 8

So, now (4 years earlier), the ages must be ...

  father: 36; son: 4.

Kazeer [188]
Wait let me know that the .12 means in the first question and i will fix the answer

int (x)(cosx) dx 

u=x      ----> take derivative     du=dx
dv=cosx    -----> take integral  v=sinx

now use integration by parts 

u v - int (v)du
x sinx - int (sinx) (1) dx=

x sinx  - (-cos(x)) + c =

answer is = x sinx + cosx + c
