3.0, because the 3 is in the ones place.
Answer:
A. 0.50
B. 0.85
C. 0.05
Step-by-step explanation:
A. Based on the initial statistics, 50% of the blood type is blood type O, hence the probability of choosing bold type O at random is 50/100, which is 0.50 to two decimal places.
B. The total number of donors that can donate to Blood type A is 85%, thus, the probability is 85/100, which is 0.85 to two decimal places.
C. The percentage of people that have the type AB blood is 5%, thus the probability of someone having the A antigen and blood type AB is 5/100, which is 0.05 to two decimal places.
Answer:
The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.
Step-by-step explanation:
When we do not know the shape of the distribution, we use the Chebyshev's Theorem to find the minimum percentage of a measure within k standard deviations of the mean.
This percentage is:
Within 8 standard deviations of the mean
This means that 
. So
The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.
Answer:
(4,-1) (4,0) (4,1)
Step-by-step explanation:
If you graph this, it will be a straight vertical line. No matter what y is, x will always be 4.
