Answer:
1. 700
2.1050
Step-by-step explanation:
you add 310 and 390 and get 700
350 plus 700 is 1050
If the question is 3^(2/3),
The answer is the cube root of 9.
I'll get you started:
mean = np = (500)(.56) = ?
standard deviation = √npq = √(500)(.56)(.44) = ?
Note: q = 1 - p
Finish the calculations.
To find z-score:
z = (x - mean)/sd
Note: x = 250
Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.
Answer:
2
Step-by-step explanation:
la respuesta es 2
Taking the difference of the both you can see that 2 kg of gummy bears would cost $18. So each kg of gummy bear is $9. Now subtract $9 from what Erika bought, and 3 kg of red hots are $12. So each kg of red hots are $4.
