Step-by-step explanation:
The lengths of human pregnancies are normally distributed with a mean of 268 day and a standard deviation of 15 days
From the information given,
mean, u =268
standard deviation, s = 15
x is number of days
For normal distribution,
z = (x-u)/s
Probability of x greater than or equal to 300 will be 1 - probability of x lesser than 300
z = (300-268)/15 =32/15 = 2.13
Looking at the normal distribution table, the value is 0.98341
Probability of x greater than or equal to 300 will be 1 -0.98341
= 0.01659
10x^2+15x+0=0
take the -15x to the other side so becomes positive and place the 10x^2 first bc of standard formula
Answer:
y=6
Step-by-step explanation:
|10-5y|=20
Since the absolute value is isolated, we can then separate the equations
For absolute values, there is a positive and negative when we remove the absolute values.
10-5y = 20 10-5y= -20
Subtract 10 from each side
10-10-5y = 20-10 10-10-5y= -20-10
-5y = 10 -5y = -30
Divide by -5
-5y/-5 =10/-5 -5y = -30/-5
y =-2 y =6
