I dont know exactly what your asking but 145% of 24 is 34.8
and 24% of 145 is 34.8
i guess they came out the same lol
Let the lengths of pregnancies be X
X follows normal distribution with mean 268 and standard deviation 15 days
z=(X-269)/15
a. P(X>308)
z=(308-269)/15=2.6
thus:
P(X>308)=P(z>2.6)
=1-0.995
=0.005
b] Given that if the length of pregnancy is in lowest is 44%, then the baby is premature. We need to find the length that separates the premature babies from those who are not premature.
P(X<x)=0.44
P(Z<z)=0.44
z=-0.15
thus the value of x will be found as follows:
-0.05=(x-269)/15
-0.05(15)=x-269
-0.75=x-269
x=-0.75+269
x=268.78
The length that separates premature babies from those who are not premature is 268.78 days
Well we know 4% is just 4/100.
So 20 = 4/100.
Let's find out what 1/100 is and multiply that by 100:
20/4 = 5.
So 1/100 = 5.
5*100 = 500.
Answer:
0
Step-by-step explanation:
Quadratic equation
The discriminant is the part of the quadratic formula within the square root symbol: 
. The discriminant indicates if there are two solutions, one solution, or none.
The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.
So, a positive discriminant tell us that the quadratic has two different real solutions.
A discriminant of zero tell us that the quadratic has two real and equal solutions.
And a negative discriminant tell us that none of the solutions are real numbers.
In this case: 25x^2-10x+1=0
We can see that
a= 25 b=-10 c=1
Using:
We have 
the answer is zero, so the quadratic has two real and equal solutions

I'm pretty sure this is right? Unless I'm missing something, if I am I am terribly sorry.
