Answer:33
Step-by-step explanation: i just did the problem
In normal distributions, the 95th percentile means that a value exists within 2 standard deviations of the mean.
The mean is 175 Lbs and SD is 15 Lbs. This means that Harvey's weight will be within 2 standard deviations (each way) of the mean. I.e. his weight will be in the range 145 - 205 Lbs.
4(3/(8+1) = 4(3/9) = 12/9 = 4/3
4((3/8)+1) = 4(11/8) = 44/8 = 11/2
just depends on which way the equation is written
Answer:
x=2
Step-by-step explanation:
2(1+3x)=14
Divide each side by 2
2/2(1+3x)=14/2
1+3x = 7
Subtract 1 from each side
3x =7-1
3x = 6
Divide by 3
3x/3 = 6/3
x =2
So will be choice D.
bc. 5/6 = 10/12 = 2*5/2*6 = 5/6
