<h2>Answer:</h2>

The correct answer is:

        Probability of C = 0.1 ; Probability of D = 0.1

<h2>Step-by-step explanation:</h2>

We know that in any probability distribution with 4 events as:

        A,B,C and D.

The probability of all the events of the distribution sums up to 1.

i.e.

P(A)+P(B)+P(C)+P(D)=1

⇒ 0.5+0.3+P(C)+P(D)=1

⇒ 0.8+P(C)+P(D)=1

⇒ P(C)+P(D)=1-0.8

⇒ P(C)+P(D)=0.2

Also we are given that:

         P(C)=P(D)

This means that:

         2 P(C)=0.2

⇒   P(C)=0.1

Hence, we have that:

  Probability of C is 0.1 and Probability of D is 0.1

Frank is using a cookie recipe that calls for 2 ¼ cups of flour. The recipe yields 20 cookies. How much flour would be needed to
larisa86 [58]

Hey there! I'm happy to help!

How many times does 20 go into 48?

48/20=2.4

So, we multiply our amount of flour for 20 cookies by 2.4.

2.25×2.4=5.4

Therefore you would need 5.4 or 5 2/5 cups of flour to make 48 cookies.

Have a wonderful day! :D

Estimate the distance you can travel in 3 hours 20 minutes if you drive on average 49 miles per hour. Round your answer to the n
AlexFokin [52]

Answer:

163 miles

Step-by-step explanation:

set up a ratio based on 49 miles in 1 hour (60 minutes):

let 'd' = distance in 3hrs, 20 min

3hrs, 20 min = 200 minutes

49/60 = d/200

cross-multiply:

60d = 9800

d = 163.3

What is the coefficient of a3 after simplifying this expression? 2a3−10ab2+3a3−ab2−7
Sergio [31]

Answer:

<h3>5</h3>

Step-by-step explanation:

Given the expression

2a^3−10ab^2+3a^3−ab^2−7

We are to find the coefficient of a^3

First is to collect the like terms;

2a^3−10ab^2+3a^3−ab^2−7

= 2a^3+3a^3−10ab^2−ab^2−7

= 5a^3-11ab^2-7

From the resulting equation, you can see that the coefficient of the term having a^3 is 5
