Answer:
a) Since the distribution is normal, the distance from the mean to the upper limit is going to be the same as the distance from the mean to the lower limit. The mean is going to be the mid point between the limits, which is going to be the average of the limits. The limits are going to have a z score associated, in this case the upper z is 1.96 and the lower z is -1.96 as shown in the picture.
(4.4 + 6.0)/2 = 5.2
The mean for men is going to be 5.2 million cells/uL
b) The standard deviation for men can be calculated using the z score and the limit values. The formula is shown in the picture.
σ = (6.0 - 5.2)/1.96 = 0.4
The standard deviation is 0.4 million cells/uL
Answer:
use FOIL- Firsts Outsides Insides Lasts
- Multiply the -4 and -3 as they are the first numbers of each brackets -4x-3=12
- Next the outsides so -4x6i as they are on the outskirts of each brackets -4x6i= -24i
- Insides so 3i and -3 as they are in the centre of the two brackets 3ix-3= -9i
- Lasts so 3i and 6i as they are at the end of each bracket 3ix6i=18i^2 ( i squared)
- add the answers together - 12+-24i+-9i+18i^2= 12-24i-9i+18i^2
- Simplify by adding like terms which is -24i and -9i.
<h3>12+-33i+18i^2 is the answer </h3>
Hi,
The answer is 4 sq. . cm,
If you see closely, it is nine times smaller, so we divide 36/9=4
So the area of the smaller figure is 4 sq. cm.
Hope this helps you.

C. 1,300
I cant see the expression but i got 1,100 by finding out what 80% of 1500 is by multiplying 1500 by 0.8 to get 1,200. Then add the 100 that you have to pay for the membership +to get a total of $1,300. hop dat dis iz help fuuull
Answer:
Hi,
In a square, all sides are equal.
The area is obtained by multiplying one side by another side.
So, A = L^2
A = Area
L = length of a side
24ft^2 = L^2
L = square root(24) = 4.9
L = 4.9
We can say x^2 = 24
And the length of one side is therefore 4.9
