Answer:
After 7 hours will be 1.95489493x10^12 viruses
Step-by-step explanation:
If the virus spread with 19% per hour after one hour it will increase 57 and continue in the 300+((300*0.19)^7) form, we just need to caculate the form
Answer:
The 95% confidence interval for the average heights of the population is between 1.7108m and 1.7892m.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The standard deviation is the square root of the variance. So
Then
The lower end of the interval is the mean subtracted by M. So it is 1.75 - 0.0392 = 1.7108m
The upper end of the interval is the mean added to M. So it is 1.75 + 0.0392 = 1.7892m
The 95% confidence interval for the average heights of the population is between 1.7108m and 1.7892m.
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
The number of freshmen entering college in a certain year = 621
It is considered as discrete data.
Since we know the definition of Discrete which refers to all types of data which take only numerical values.
It is based on counts.
According to question, we have given the exact number of freshmen instead of any range or interval.
Hence, Third option is correct.
x + x + 1 + x + 2 + x + 3 = 130
Combine like terms.
4x + 6 = 130
Subtract 6 from both sides.
4x = 124
Divide both sides by 4.
x = 31
<h3>The first digit is 31.</h3><h3>The second is 32.</h3><h3>The third is 33.</h3><h3>The fourth if 34.</h3>
