Step-by-step explanation:
(a) 860
860 ends with a zero or a five, 186 and 863 do not.
(b) 860
860 ends with a zero, 186 and 863 do not.
(c) 860, 186
860, the 0 is even. 186, the 6 is even. 863, the 3 is not even.
Answer:
Step-by-step explanation:
Suppose :
62% own an HDTV
16% own a computer
Using the addition rule : suggests that (62% + 16%) = 78% either own an HDTV or a computer.
The reasoning is wrong because ; since it is possible to own both an HDTV and also own a computer at the same time, the outcome of the addition rule is wrong as both events are independent. If both event cannot occur at the same time (mutually exclusive event) , then, the addition rule may be applied,. But since both can occur independently and each family can own an HDTV while also owning a computer, then the addition rule is wrong for the scenario described.
So, Jerome bought a total of 80 cards (8x10) out of which he gave out 30 cards (3x10) so he has 50 cards left. (80-30)
Answer:140
Step-by-step explanation:
24/20=168/N
Cross product
24×n=168×20
24n=3360
n=3360/24
n=140
Answer:
The expression represents JL is<u> 3x - 2</u>.
Step-by-step explanation:
Given:
JM = 5x – 8 and LM = 2x – 6.
Now, to find expression represents JL.
JM = JL + LM
<em>Subtracting both sides by LM we get:</em>
JM - LM = JL.
JL = JM - LM
Now, putting the expression to get JL:
Therefore, the expression represents JL is 3x - 2.
