Answer:
the answer for this question is 18 because first of all remember to use the rule 4x-2 to find the last one and you replace it with 5 so 4(5)-2= 20-2=18 so 18 is the correct for the last one and have a great day.
4(3)-2= 12-2=10 for the first one if you wanted to kind of knowing that.

Answer:
0.40517 is the probability
Step-by-step explanation:
The first thing to do here is to calculate the corresponding z-score
Mathematically;
z-score = x-mean/SD
from the question,
x = 78, mean = 75 and SD = 12.5
Plugging these values in the z-score equation, we have;
z-score = (78-75)/12.5 = 3/12.5 = 0.24
So the probability we want to calculate is that;
P(z < 0.24)
we can get this by using the standard normal distribution table,
The value according to the table is;
0.40517
X=-3... -21/7=-3........m

Answer:
All of the values that can go into a relation or function (input) are called the domain. ... The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
