Answer:

a. 0.308 = 30.8% probability that a red ball is drawn.

b. 0.816 = 81.6% probability that the ball drawn is not white.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

308 + 184 + 508 = 1000 balls

a.A red ball is drawn

308 balls are red. So

308/1000 = 0.308

0.308 = 30.8% probability that a red ball is drawn.

b.the ball drawn is not white.​

1000 - 184 = 816 are not white.

816/1000 = 0.816

0.816 = 81.6% probability that the ball drawn is not white.

Consider the following expression.<br> 5(1+6) (2b+7)<br> Select all of the true statements below.
Vesna [10]

<u>Answer:</u>

  • Option B
  • Option C
  • Option E

<u>Explanation:</u>

  • <em>Option B is true because both of the terms are constants. Hence, they are like terms.</em>
  • <em>Option C is true because the coefficient of a term is basically the constant. If there is no constant, then the coefficient is 1.</em>
  • <em>Option E is true because the expression has been multiplied by 5. </em>

Bippity boppity pls help me find this functions property
Semmy [17]

Answer:

Period ⇒ 40

Amplitude ⇒ 12

Mid-line ⇒ 32

Step-by-step explanation:

The table is counting by 4's and the period is the amount of space between 2 peaks. In this scenario, we can find the peaks by looking for two of the same highest value (44). We can see that x=40 has a value of 44 while the other is actually not shown because it would be located at x=0. Therefore the period is 40

<u />

The amplitude can be found by using the following:

\frac{1}{2}|max - min|

Our maximum is 44 and our minimum is 20.

\frac{1}{2}|44 - 20|

\frac{1}{2}|24|

\frac{1}{2}(24)

The amplitude is 12

The amplitude is the distance from the peak to the mid-line. To find the mid-line, we can either subtract our amplitude from our maximum value (44) or add our amplitude to our minimum value (20)

44 - 12 = 32

20 + 12 = 32

Therefore our mid-line is y = 32

~Hope this helps!~
