Answer:
And we can find this probability with this difference and using the normal standard table:
Then the answer would be approximately 55.3% of women between the specifications. And that represent more than the half of women
Step-by-step explanation:
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference and using the normal standard table:
Then the answer would be approximately 55.3% of women between the specifications. And that represent more than the half of women
(2,4) is the only possible answer because it is the only one in the shaded area
Intersect at where x=x and y=y
see where they have the same x and y values
that is at x=-1 and y=-5
intersect at (-1,-5)
Answer:
0.95
Step-by-step explanation:
Answer:
y=8/(p+q+4)
Step-by-step explanation:
py+qy=-4y+8
Collect all terms containing y together
Py+qy+4y=8
Factor out y
y(p+q+4)=8
Divide both sides by (p+q+4)
y(p+q+4)/(p+q+4)=8/(p+q+4)
y=8/(p+q+4)
