1/10=x hope that helps a bunch
Your answer is unlikely. That would be a 1 out of 10 chance.
I guess that u = μ & that a=σ. If so:
μ =100 & that σ =20 & x=20
Z score = (x-μ) / σ ==> Z score = (90-100)/20 ==> Z = - 0.5
Simplify it or what if so then the answers would be r>48
y<(line under it)6
Student A starts with $100 in the bank and makes $5 a day. Student B starts with $50 and makes $7 a day. Assuming the students save their money, when will they have the same amount of money ?
