S and P are mutually exclusive events.
P ( S ) = 20% = 0.20
P ( T ) = 22 % = 0.22
The probability of mutually exclusive events:
P ( S or T ) = P ( S ) + P ( T )
P ( S or T ) = 0.20 +0.22 = 0.42
Answer: The probability of ( S or T ) is 0.42 or 42 %.
Answer:
1.39626
Step-by-step explanation:
80° × π/180 = 1.396rad
The additive inverse of an expression is composed of terms which bear the opposite sign of the equivalent functions such that when the two functions are added, the sum is zero. In this case, the additive inverse of +4x is B-4x.
<span>2. a) 4x + (4 -x) = 0
</span> 4x + 4 -x = 3x + 4 is not equal to 0.
<span> b) 4x + (-4x) = 0 additive inverse
</span> c) <span>4x + (1/4x) not equal to zero should use multiplicative inverse
d) </span><span>4x + x - 4 = 5x - 4 is not equal to zero</span>
Answer:
Option A:
Yes, it is proportional because it has a constant rate of change.
Step-by-step explanation:
One trick you can use to easily tell a proportional graph is that it follows a straight line. It does not matter whether the line slopes downwards or upwards. The fact that it is straight and not cured at any point, should hint you that the graph is proportional.
Proportional graphs have a constant rate of change. The value of the slope calculated when using any two (x, y) coordinates are the same for any point along the line.
Column Resolution
Rs = 2[(tr)y - (tr)x]/[Wx + Wy]
= 2[17.63 - 16.4]/ [1.11 + 1.21] = 1.06
Average no. of plates in the column for substance x
N = 16(tr/ W)^2
N = 16(16.4/1.11)^2
N = 3490 plates
Average no. of plates in the column for substance y
N = 16(tr/ W)^2
N = 16(17.63/1.21)^2
N = 3397 plates
Plates Height
H = L/N
For substance x
H = 30/3490
H= 0.00916905 cm/plate
For substance y
H = 30/3397
H = 0.00883132 cm/plate
