Answer:
DE= 39°
Step-by-step explanation:
(4w+ 4 )+(4w+8)= 180
Solve for w
8w + 12 = 180
8w = 180-12
8w = 168
W= 21°
(4w+ 4)+(2w+11)+DE = 180
But w= 21°
((4*21 )+4)+((2*21)+11)+DE = 180
88 + 53 + DE = 180
DE = 180-88-53
DE= 39°

Answer:
The Theoretical probability is 1/6.
The experimental probability is 1/5
Step-by-step explanation:
Given
Rolls: 100
Outcome of 3 : 20
Required
Which of the options is true (See attachment for options)
From the attachment, we understand that the question requires that we calculate the experimental and theoretical probability.
The experimental probability (E) is calculated as thus:



The theoretical probability (T) is calculated as thus:
A cube has 6 faces, one of which is the face 3.
So, T is:


Hence, C is true
Answer: 33.3%
Step-by-step explanation:
First find the number of green balls in the basket:
= Total - yellow - blue - red
= 18 - 4 - 6 - 2
= 6 balls
The probability of picking a green ball can be found by the formula:
= Number of green balls / Number of total balls
= 6 / 18
= 33.3%
Y=mx+b
m= slope so slope= .5
b= y intercept so y intercept=0
