This condition must be observed for the case of a quadratic equation with equal roots:




Answer:
0.74 to 6.06
Step-by-step explanation:
The groups are independnet,
SE(xh bar-xa bar)=sqrt [sh^2/nh+sa^2/na]=sqrt [10.1^2/80+10.3^2/80]=1.61
At df=157, the t critical is 1.65
90%c.i=(xh bar-xa bar)+-tcritical SE(xh bar-xa bar)
=(25.2-21.8)+-1.65*1.61
=0.74 to 6.06
Started with: $60
left with: $10
items bought: 20
60 - 10 = 50 < amount spent
50/20 = amount spent/items bought
= $ 2.50 < each chocolate
you can check this by multiplying the items bought and the amount each item cost to get how much you spent
20 × 2.5 = 50
Stephanie started off with 60 dollars and ended with 10 dollars
60 - 50 = 10
hope this helps :)
