Answer:
Option 4 is correct
Step-by-step explanation:
The formula of the Trigonometric Identity Sine is,
8a - 1 + 0.5b = 8(1/4) - 1 + 0.5(10)
= 2 - 1 + 5
= 1 + 5
= 6
<u>Answer:</u>
Option c)
The pair does not represent the probabilities of complementary events is 0.25 and 0.50
<u>Explanation:</u>
Probability of complementary events signifies that the sum of the respective probabilities should always add up to 1. That means when the sum of the probability of the individual terms cumulates into 1 then the event performed is a complementary event.
a)Probability of event 1 = 4/7
Probability of event 2 = 3/7
Sum of the events = P(E1) + P (E2)
= 4/7+3/7=7/7=1
Hence it is a complementary event
b)Probability of event 1 = 16% = 0.16
Probability of event 2 = 84%= 0.84
Sum of the events = P(E1) + P (E2)
=0.16+0.84
=1
Hence it is a complementary event
c)Probability of event 1=0.25
Probability of event 2= 0.50
Sum of the events = P(E1) + P (E2)
= 0.25+0.50
=0.75
Since the sum is not 1
Therefore it is not a complimentary event
d)Probability of event 1= 1
Probability of event 2= 0
Sum of the events = P(E1) + P (E2)
= 1+0
=1
Hence it is a complimentary event
It means that it does not equal to that certain amount, which is why they put a line across it

Answer:</h2>
The statement that is true about the radius of a sphere is:
The radius is a line segment from the center point to the surface of the sphere.
<h2>
Step-by-step explanation:</h2>
We know that the radius of a circle/sphere is a line segment that joins the center of circle/sphere to any point on the circumference/ surface of the circle/sphere.
Also, in a circle the radius is the length such that each point on the circumference are equidistant from the center of the circle.
