Answer:
From what I can tell from the image, b is equivalent to B.) 50°
Step-by-step explanation:
So to start off 2a=80° there is 2 a's. so you subtract 80° from 180° to get 100°.
now b=c and their is 100° left over. So 100°/2 is 50° because if b=50° and c=50° both angles equal 100°.
Answer:
the distance equation is
Step-by-step explanation:
Let's assume
time in hours as 't'
distance traveled as 'd' meters
We are given
Moves 2 meters every 3 hours
So, firstly we find speed
we know that
distance = (speed)*(time)
now, we can plug values
now, we can plug value
So, the distance equation is

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
It is given that;
Margin of error E = 0.7
Confidence interval 98% = 1-0.98 = 0.02
Standard deviation = 6 hours
Number of MRI machines needed per day n, = [(z alpha/2 * SD)/E]²
Z alpha/2 = 1.645 at alpha = 0.1
Inputting these values into n we have that
[(1.645*6)/0.7]²
= 14.1²
= 198.81 is approximately equal to 199
The company has to study 199 machines.

Answer:
C
Step-by-step explanation:
S= (2M-15)=185
2m=185+15= 200
m=200÷2= 100cm-C
