Answer:
The correct approach will be "the likelihood of cashing the coupon".
Step-by-step explanation:
- That what's being examined as well as calculated throughout the experiment or observational study seems to be the dependent variable (almost always widely recognized as that of the responding variable). As a consequence of the modifications to something like the independent variable, that's what modifications.
- Whether large you are really at various ages would be an illustration of some kind of dependent variable.
Answer:
If our random variable of interest for this case is X="the number of teenagers between 12-17 with smartphone" we can model the variable with this distribution:
And the mean for this case would be:
And the standard deviation would be given by:

Answer:
$65.35
Step-by-step explanation:
- First you have to divide 5.4% by 100
- Take 5.4/100 and multiply it by 62
- Take the number you get from step 2 and add it to 62! (:
Answer:
formula: y-y1 = m(x-x1)
Step-by-step explanation:
General:
1. find 2 points directly on the line and apply the formula y2-y1 over x2-x1 this answer equals m
2. then add it into the formula y-y1 = m(x-x1) remember x and y are variables so only put numbers in y1 and x1
3. solve the problem
Example:
line 1:
1. y2-y1 over x2-x1 is 4-6 over 6-4 = -1
2. y-6 = -1(x-(-4) or y-6 = -1(x+4)
3. y-6 = -1x-4
4. y = -1x-2
3. the gradient equals: y = -1x-2
Hope this helps :) Let me know if you need a better example
