Answer: 0.2119
Step-by-step explanation:
We assume that the random variable X is normally distributed.
Given : Population mean : 
Standard deviation : 
Z-score : 
Then, z-score corresponds to 116
By using the standard normal distribution table for z , we have
Hence, the required probability = 0.2119

Answer:
x=10, y=4
Step-by-step explanation:
3x-3y=18
(-)3x-(-)8y=-(-)2 -3x+8y=2 add to first equation to eliminate x
5y=20
y=4
substitute y with 4
3x-3(4)=18
3x=30
x=10
x=10,y=4
Answer:
4 and 8
Step-by-step explanation:
The square of 4 is 16 and the square of 8 is 64.
16 + 64 = 80
we need to find 1% of 10000 first
so we divide 10000:100= 100 (that's 1%)
to find the 60% which will be accepted we multiply 100 × 60 = 6000 students accepted
of those 6000 we need to find 50% which is ½ so we basically just divide by 2, aka 6000 : 2 = 3000 people which will be enrolled
