Answer: 529 possible outcomes
Step-by-step explanation:
You square the number of games as many times as the outcomes (win or loss)
2 outcomes = 23 * 23
23 * 23 = 529
Since there are 2 outcomes, you multiply 2 23’s together to get the number of possible ways.
Midnight to 3 a.m.: 20%
3 a.m. to 6 a.m. 5%
Midnight to 6 a.m. = 20% + 5% = 25%
Answer:
3.06
Step-by-step explanation:
The correct answer is - 3.06
Reason -
For sample A :
mean, = 8.05
Standard deviation, = 1.36
Size, = 50
For sample B :
mean, = 7.26
Standard deviation, = 1.06
Size, = 38
Now,
- = 8.05 - 7.26 = 0.79
Standard deviation error, SE = √(²/ + ²/) = 0.2580
Now,
Z-statistic = ( - )/ SE
= 0.79/0.2580
= 3.06
⇒Z-statistic = 3.06
4x+y+4z=0
=4x+4z-y=0
=4(x+z) +y=0
