Answer:
3
Step-by-step explanation:
12-4=5 and 1+3+1 also equals 5.
Get the mixed number into one fraction

Get a common denominator

Now add

You can get it back to a mixed number
The answer to this would be parentheses zero, -2 parentheses
Answer:
Poisson distribution.
Step-by-step explanation:
We have the mean number of missing pulses per disk, which means that the distribution for X, the number of missing pulses, will be the Poisson distribution.
It is not the binomial distribution because we are not given the probability of a missing pulse on a disk, but the mean number of missing pulses.
Answer:
Answer is option a ) 0.53
Step-by-step explanation:
slope = 
Given that a pediatrician wishes to study how the average weight Y (in kilograms) of children changes during the first year of life. He plots these averages versus the age X (in months) and decides to fit a least-squares regression line to the data with X as the explanatory variable and Y as the response variable.
He finds the following quantities:
r = correlation between X and Y= 0.84
x = mean of the values of X = 5.69
y = mean of the values of Y = 6.26
S_x = standard deviation of the values of X = 3.23
s_y = standard deviation of the values of Y = 2.04
Using the formula for slope given above substitute to get

round off to 0.53
Answer is option a ) 0.53
