30 bacteria
Step-by-step explanation:
Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.
Circumference = 2 pi r
2 pi r = 200
r = 100 / pi
Area of base = pi r r
Area of base = 100*100 / pi
Area of base = 3183.1 sq. m.
Answer:
Coordinates of Q 
Option D is correct option.
Step-by-step explanation:
We are given:
K is the midpoint of PQ
Coordinates of P = (-9,-4)
Coordinates of K = (-1,6)
We need to find coordinates of Q
We will use the formula of midpoint: 
We are given midpoint K and
the coordinates of P we need to find
the coordinates of Q.

Now, we can write

So, we get coordinates of Q 
Option D is correct option.

Remark
A good thing to understand is that when a whole number and a fraction are multiplied, the method is the same as multiplying 2 fractions. What that means is make the whole number into the numerator of a fraction and put a 1 where the denominator should be.
Solution
4/1 * 2/3 = 4*2 / 1 * 3 = 8/3
