A disjunction is a statement formed by combining two statements with the word and is FALSE.
Answer: B) False or the second option.
D. The exclusion is important because we cannot divide by zero. Apart from that we are simply looking at a function.
If you're evaluating, then multiply by the conjugate and simplify.
= -1 -i
The answer would be the same even if you divided...and or, wrote it in simplest form.
The probability that the sample mean is less than 30 school days will be given as follows:
the z-score is given by:
z=(x-μ)/σ
where
μ- stand deviation
σ-mean
thus the z-score of our information is:
z=(30-28)/9
z=0.222222
hence the probability that the sample mean is less than 30 will be:
P(x<30)=0.5871~58.71%
Answer:
Step-by-step explanation:
∠FGD = ∠CGE {Vertically opposite angles}
∠FGD = 15°
∠AGF + ∠FGD = 90°
x + 15 = 90
x = 90 - 15
x = 75°
