A. yes, because the mean is larger in the english book.
Let the diagonal be a.
now, as we know that each angle in a rectangle is right angle.
thus we have a right angled triangle.
now, we can apply pythagoras theorum.
a^2 = 54^2 + 72^2
= 2916 + 5184
=8100
thus, a^2 = 8100
thus, a = 90.
Thus the diagonal is 90metres
Answer: a) 0.1587 b) 0.0618
Step-by-step explanation:
Let x be the random variable that represents the monthly demand for a product.
Given : The monthly demand for a product is normally distributed with mean = 700 and standard deviation = 200.
i.e. and
a) Using formula , the z-value corresponds to x= 900 will be :
Now, by using the standard normal z-table , the probability demand will exceed 900 units in a month :-
Hence, the probability demand will exceed 900 units in a month=0.1587
a) Using formula , the z-value corresponds to x= 392 will be :
Now, by using the standard normal z-table , the probability demand will be less than 392 units in a month :-
Hence, the probability demand will be less than 392 units in a month = 0.0618
Answer:
y>4
Step-by-step explanation:
3y>12
divide both sides by 3
y>4
draw a dotted horizontal line at 4 on the y-axis
shade the entire section above it
