Well just do regular math to answer but if its looking for pattern u can tell that the consistent number is 7
Answer:
v=kw. 8=k1/2
Step-by-step explanation:
Okay, so here's the equation. v=kw. Varies directly means if v rises, then w rises. If v decreases, then w will decrease. Let me know if that helps! (In case you need it, k=16.)
Answer:
d
Step-by-step explanation:
Answer:
3630
Step-by-step explanation:
726*5
= (700+20+6) * 5
= (700*5) + (20*5) + (6*5)
= 3500 + 100 + 30
= 3600 + 30
= 3630
Answer:
1.4
Step-by-step explanation:
Probability of selecting a red counter :
Number of red counter / total number of counters
5 / (5 + 3) = 5 /8 = 0.625
Probability of selecting a blue counter = 0.375
Let number of red counters :
0, 1 or 2
0 red counters :
Expected value = x * p(x)
0 + (0.625*1) + (0.390625 * 2)
0 + 0.625 + 0.78125 = 1.40625
Expected number of red counters = 1.4
