The missing interval is 21 - 25

Question 2: How many tally marks to draw?

The frequency is given as 3, so draw three tally marks: III

Question 3: How many tally marks to draw?

The frequency is given as 2, so draw two tally marks: II

Question 4: What is the frequency?

There are eight tally marks so the frequency is 8.

Question 5: What is the frequency?

There are four tally marks so the frequency is 4.

Assume that P(E) = 0.471 and P(F) = 0.595. If E and F are independent, find P(E and F)

dsp73

The value of the probability P(E and F) is 0.2802

<h3>Independent probability</h3>

Events are known to be independent if the occurrence of one does not affect the other.

Given the following parameters

P (E) =0.471

P(F) = 0.595

If E and F are independent, then;

P(E and F) = P(E)P(F)

P(E and F) = 0.471 * 0.595
P(E and F) = 0.2802

Hence the value of the probability P(E and F) is 0.2802

What is the additive inverse of the complex number 9-412 -9-41 -9 +41 9 - 41 9 + 41

Studentka2010 [4]

Additive inverse means the sum should be 0

so all you gotta do is multiply the complex number by -1

(the question isn't clear so I can't state the option)

Y/3 + 8 = -2 solve for y a. -30 b. -18 c. 18 d. 30

Rainbow [258]

Answer:

$\large\boxed{a.\ -30}$

Step-by-step explanation:

$\dfrac{y}{3}+8=-2\qquad\text{subtract 8 from both sides}\\\\\dfrac{y}{3}+8-8=-2-8\\\\\dfrac{y}{3}=-10\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{y}{3\!\!\!\!\diagup_1}=(3)(-10)\\\\y=-30$
