Answer:

A


Step-by-step explanation:

We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.


<em>There are 50 in total, and 8 of them are red, so:</em>

P(red) = \frac{8}{50}=0.16


<em>Now we multiply this with 500 to get:</em>

500*0.16=80


The correct answer is A.

Answer:

Marcie should expect 80 red marbles. Correct answer is (A).

Step-by-step explanation:

First we need to calculate the probability of red marble to come from the bag of 50 marbles.

P=\frac{Favourable condition}{Total condition}

P=8/50

Now the chances of getting red marble after 500 trail is calcualted as

x=P*500

=(8/50)*500

=80

Therefore the correct answer is (A).

Graph the function. Describe its position relative to the graph of the indicated basic function.
masya89 [10]

Answer:

The answer is (b) moved right 3 units and moved down 3 units

Step-by-step explanation:

∵ f(x) = 4^x ⇒ red in the graph

∵ f(x) = 4^(x-3) - 3 ⇒ blue in the graph

∵ x  becomes x - 3 ⇒ means:

 The graph moved right 3 units

∵ f(x) = 4^x becomes 4^(x-3) - 3 ⇒ means:

  The graph moved down 3 units

∴ The answer is (b)
