Answer:
216 degrees
Step-by-step explanation:
Given that ABCDE is a regular pentagon.
Hence each angle would equal = {2(5)-4}/5 right angles
=6(90)/5 =108 degrees
Since regular pentagon rotation will not disturb the shape.
When counterclockwise rotated, if 108 degrees rotated A would become E.
For another 108 degrees A would come to D
Hence angle required for rotation for A to coincide with D = 2(108)
=216 degrees
Step-by-step explanation:
Hey there!
Given;
4(X+1) -3 and 4x+1.
No, they are equivalent.
<u>Reason: </u>
Solving 1st expression.
4(x+1) = 4x + 4 - 3
Now, next expression is: 4x+1.
So, 4x + 4 = 4x+1
So, they are equivalent to eachother.

Answer:
False
Step-by-step explanation:
The implication ...
true → false . . . . . . . not true
is the only implication with a truth value of <em>False</em>. All other combinations have a truth value of <em>True</em>.
true → true . . . . . . . . . . true
false → (anything) . . . . true
The probability that exactly 4 are cured from 7 dolphins is 0.0128
<h3>What is Probability ?</h3>
Probability is the likeliness of an event to occur and it has a range of 0 to 1, where 0 means unlikely and 1 indicates certainty of the event to happen.
It is given that the 92% of all the dolphins are cured of an ear infection ,When treated with an antibiotic
If there are total dolphins given as 7
On the basis of given data
The dolphin that cannot be cured is given by
1 - p = 1 - (92/100) = 0.08 = 8/100
q = (8/100)
n= 7
r = 4
Therefore by Binomial Distribution
Putting the values
P = 0.0128
Therefore the probability is 0.0128.
