The difference between 38 and 18
The numerical expression is

Step-by-step explanation:

In the field of mathematics, the difference is the result of subtraction (one of the basic operations of arithmetic). The subtraction is to remove a certain amount (Subtrahend) of a number (Minuend). The resulting quantity is the difference.

In this sense, the numerical expression for the difference between 38 and 18 is:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
