Answer:
a) 279 b)254
Step-by-step explanation:
Mean = 269 days
standard deviation = 8 days
let n be the pregnancy lenght.
using normal distribution formula
z = (n – mean)/ standard deviation
n = z * standard deviation + mean
Now, z values for the top 12% has to be found using a z table.
The top 12% means 88% of area under the curve. In this case z = 1,176
n = 1,176 * 8 + 269
n = 278.4 = 279
The bottom 3% means 97% of area under the curve. In this case z = -1,882
n = -1,882 * 8 + 269
n = 253.94 = 254
It could be 30 to 31 but February has 28 expected from a leap year with 29 days
Answer:
Seven numbers.
Step-by-step explanation:
Finding the numbers, which are equal to the sum of two odd number and it has to be single digit number.
Lets look into numbers which are odd and single digit.
1 = 
∴ Sum of the number is 
3 = 
∴ Sum of above number is 
5 = 
∴ Sum of above number is 
7= 
∴ Sum of above number is 
Now, accumlating numbers which are fullfiling the criteria, however, making sure no number should get repeated.
∴ Numbers are: 
Hence, there are total 7 numbers, which are equal to the sum of two odd, one-digit numbers.
Yea it’s B because I did the mathhhhhh
