4x^2+25=4x^2=-25=x^2=-25/4 has no solution. because, negative number do not live under radical except complex number
Answer:
1. 94.25 is the surface area, 94.25 to 56.55 is the ratio of surface area to volume
2.138.23 is the surface area 138.23 to 113.1 is the ratio of surface area to volume
Answer:
Option 3 is right
z37 is between 2 and 3 standard deviations of the mean.
Step-by-step explanation:
Let X be a random variable which represents the mean number of miles that the employees in a department live from work
X is normal (N(29,3.6)
WE have to find Z score for X
Z =
=2.22
i.e. 37 is 2.22 std deviations from the mean.
In other words, z37 is between 2 and 3 standard deviations of the mean.
X=year
y=$
y=200(1.003)^12x
3.6%->.036/12 (compounded monthly)
=0.003+1
y=200(1.003)^12(1) (1 year)
=$207.31999
BUT
200•12 ($200 deposited every month)
=$2400
2400+207.3199=
$2607.32
The answer she has is not correct.
All the steps she did are correct, except they forgot to convert the decimal answer into the proper percentage by multiplying it by 100.
The correct answer should be 0.125 * 100 = 12.5%
