The diagram below shows the contents of a jar from which you select marbles at random.a. What is the probability of selecting a red marble, replacing it, and then selecting a blue marble? Show your work.
b. What is the probability of selecting a red marble, setting it aside, and then selecting a blue marble? Show your work.
c. Are the answers to parts (a) and (b) the same? Why or why not?

Answers

So,

There are 4 red marbles.
There are 7 blue marbles.
There are 5 green marbles.
There are 16 marbles in total.

a.
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
$(4)/(16) \ or\ (1)/(4)$

Next, the probability of selecting a blue marble.
$(7)/(16)$

Multiply the probabilities together.
$(1)/(4) * (7)/(16) = (7)/(64)$
That is the probability for event a.

b.
Answer = (probability of selecting a red marble)(probability of selecting a blue marble)
First, the probability of selecting a red marble.
$(4)/(16) \ or\ (1)/(4)$

Next, the probability of selecting a blue marble WITH A RED MARBLE REMOVED.
$(7)/(15)$

Multiply the probabilities together.
$(1)/(4) * (7)/(15) = (7)/(60)$
That is the probability for event b.

c.
Obviously:
$(7)/(64) \neq (7)/(60)$
So the answer is no.

A giant bamboo plant grew an average of 18 centimeters per year.The botanist started measuring the plant when it was 5 centimeters tall. If "Y" represents the number of years the botanist has measured the plant,what expression represents its height?Solve,and show each step.

Answers

h=height
y=number of years.

we have the next expresion:
h(y)=my+b

m=the slope of the line, in this case, the slope is equal to "18"; (18 cm/ year).
b=the initial heigth, in this case, the initial heigth is equal to "5" (5 cm).

Therefore, our expression will be:
h(y)=18y +5

answer: h(y)=18y+5

I see the amount was $90.00 then reduced to $
75.00 , what is the percent ?

Answers

Answer:

16 2/3 %

Step-by-step explanation:

Since the price went down, we are find the percent decrease.

Percent decrease = (original price - new price)/ original price

= (90 - 75)/90

=15/90

.1666666666666

Changing to percent form

16.6666666666666666666666%

16 2/3 %

Confused, and there's a test tomorrow. "Write (5+ 2yi) (4-3i)- (5-2yi) (4-31) in a a + bi form, where y is a real number"

Answers

Answer:

12y +16yi

Step-by-step explanation:

The thing about complex numbers is that you can treat them as binomials and use all of the things you know about multiplying and factoring polynomials.

Here, we assume you have ...

(5 +2yi)(4 -3i) -(5 -2yi)(4 -3i)

The factor (4 -3i) can be factored out, so you have ...

= ((5 +2yi) -(5 -2yi))(4 -3i)

= (4yi)(4 -3i)

= 16yi -12yi²

At this point, the definition of i comes into play, and you replace i² with -1.

= 12y +16yi
