The third one is the right answer
X+10+3x+18=180 is the first part
4x+28=180
4x=152
x=38
A random variable can be either discrete or continuous. It is discrete it can assume only a finite number of values, or a countable infinity of values at most.
It is continuous if it can assume values in an interval, or in general, an uncountable infinity of values.
That being said, we have:
Option A is a discrete random variable, because the number of heads in 5 throws can be 0, 1, 2, 3, 4 or 5. So, we have finitely many possible values.
Option B is a discrete random variable, because the number you roll on a die is either1, 2, 3, 4, 5 or 6. So, we have finitely many possible values.
Option C is a discrete random variable, because if there are n students in a class, the number of boys is an integer between 0 and n. So, we have finitely many possible values.
Option D is finally a continuous random variable, because the height of a 10-year-old can be any number (in a suitable range of course).
Answer:
Step-by-step explanation:
a. true because there are 0 cookies in the box at that point
b. true because the slope is the average weight of a cookie
c. false because the number of cookies will determine the weight of the box
d. false the box is 1oz and box+1 cookie=1.25 oz so the cookie is 1.25-1= .25oz
e. true if you continue the line until 13 cookies you have about 3.75oz
