Answer:
C. 55°
Step-by-step explanation:
The computation of mAC is shown below:
Given that
Diameter AB would be parallel to CD
McD = 70
Based on the attached diagram and the above information
mAC is
= (180 - 70) ÷ 2
= 55 degrees
hence, the correct option is third
First let us calculate for the z score using the formula:
z = (x – u) / s
where x = 8, u is the mean = 12.7 years, s is the
standard deviation
z = (8 – 12.7) / 2.5
z = -1.88
From the standard probability tables, the p value at z =
-1.88 is:
P = 0.0301 = 3.01%
The area is 40in.
all you need to do is multiply all the numbers together.
8x5=40 so you area is 40in
Answer:
number of bacteria
Step-by-step explanation:
given as :
The Number of Bacteria in 2 L of water =
∵ 2 L of water have = number of bacteria
So 1 L of water have = number of bacteria
∴ 5 L of water have = × 5 number of bacteria
= number of bacteria
Hence in 5 L of water , number of bacteria available Answer
Hi
Here are the steps
4^x = 64
First, we need to solve for the exponent
log(4^x) = log(64)
Now we need to take log of
x * (log(4)) = log(64)
x = log(64)/(log(4)
x= 3
Here you go guys :)
