Answer:
The correct answers are B and C.
Step-by-step explanation:
3/10 + 1 represents an extra 30%, plus 100%. The 100% accounts for the original power of the spell. The expression can be simplified as 1.3H, or 130% of H. 130% of H can also be represented as 130/100 H.
Quotient=Division.33075/35=945
945 is your answer.
Answer:
the lowest passing score would be x = 298
Step-by-step explanation:
School wishes that only 2.5 percent of students taking test pass
We are given
mean= 200,
standard deviation = 50
We need to find x
The area under the curve can be found by:
2.5 % = 0.025
So, 1- 0.025 = 0.975
We need to find the value of z for which the answer is 0.975
Looking at the z-score table, the value of z is: 1.96
Now, using the formula:
z = x - mean/standard deviation
1.96 = x - 200/50
=> 1.96 * 50 = x-200
98 = x - 200
=> x = 200+98
x = 298
So, the lowest passing score would be x = 298
Answer:
x=2; the extraneous root x=42.
