A, B, D
A: because there are two colour types in a deck of cards, so it’s 1/2 probability of getting a black one.
B: because there a four suits in a deck of cards, so the probability of getting a diamond is 1/4
D: because when calculating compound events we multiply the two probabilities,
so 1/2 x 1/4 = 1/8
Answer:
5
Step-by-step explanation:
the base is the original number which you perform an action on. in this scenario the action is 3. 5 is being cubed
here's the solution,
slope of the line
=》
=》
=》
=》
so, slope of the line is, <em><u>-3</u></em>
Answer:
a.) First check on the height of the bar that ranges between 20 and 24 which is 6. The 6 is the number of students who bought 20 books or more, so get the percentage of those students who bought 20 or more books; divide 6 which is the number of students who bought 20 books or more with the total number of students which is 40 then multiply with 100.
% of students who bought 20 or more books = 6/40 ×100
=15
Step-by-step explanation:
b.) Find the area of a trapezium
= 1/2 × {a+b} × h
= 1/2 × {9 + 13} ×12
= 132
= 1/2 × {13 + 6} × 12
= 108
Mean no. of books bought = 132 + 108
= 240
Answer:
x=0
Step-by-step explanation:
Setting f(x)= (x-4)(x+4) = to 0 and solving for x produces the two x-intercepts (not Intersepts) of the function: They are 4 and -4.
The midpoint between these two intercepts is 0.
