Answer:
The probability is 0.017429
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD/√n
In this case;
x = 273
mean = 276
SD = √(variance) = √81 = 9
n = 40
Substituting these values into the z-score formula, we have that;
z = (273-276)/9/√40
z = -2.11
So we proceed to get the probability
the probability in this case is;
P( z < -2.11)
We can use the normal distribution table for this
Our answer will be
P( z < -2.11) = 0.017429
Answer:
41.40
Step-by-step explanation: 36*.15=5.40, 36+5.40=41.40
The answer to 0.6c+2.5=3.22 solving for C Answer:
c=1.2
Answer:
this shouldn't be that hard, if 10 is equal to 40% then you can tell that there are 15 men.
Final answer: 15
