Answer:hmm I don’t fully understand what you mean because there is no bottom of the number line it started at zero so all you have to do is fill the line in.

Answer:

get a clue from the problem statement, figure out what you need to help you solve the problem

Step-by-step explanation:

You need to read and understand the entire problem. Different parts of it give you different clues as to how to arrive at appropriate number lines.

Here are some of them:

groups of 3 red cups and 2 blue cups are circled, telling you that 3 red corresponds to 2 blue, and that this combination is one batch
each number line has 4 tick marks
part b asks for the number of blue associated with 12 red (so you might want to make sure the numbers on the red number line go that high)
part c asks for the number of reds associated with 6 blues (so you might want to make sure the blue numbers go that high)
the questions are about "batches", so the tick marks may want to correspond to batches in some way

The double number line is a tool, just as any diagram is a tool to help you solve a problem. You choose the way you draw it so that it is of help to you in answering the questions asked.

Answer:

0.5934% probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Playing at an NCAA college.

Event B: Being drafted by the MLB.

6.9% will play in an NCAA college

This means that $P(A) = 0.069$

8.6% of the college players will go on to be drafted by the MLB.

This means that $P(B|A) = 0.086$

What is the probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB?

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(A \cap B) = P(A) \times P(B|A)$

$P(A \cap B) = 0.069*0.086 = 0.005934$

0.5934% probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB

Can you guys please answer this is really important

Answer:

B) BC'= 8, m A'= 28°

Step-by-step explanation:

When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.

To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':

BC' = BC×1/2
BC' = 16×1/2
BC' = 8

The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.
