Correction:
I think the question should be like that find the approximate value of
P(-0.78 < z < 1.16)?
Now,
the symbol Ф represent the cumulative density.
first find the
Ф(1.16) from the above given table which is equal to 0.8770.
Now,
find the Ф(-0.78) .
in our table we are given the value of Ф(0.78)=0.7823
so as the curve is symmetrical Ф(-0.78)=1-0.7823=0.2177
P(-0.78 < z < 1.16) = Ф(1.16)-Ф(-0.78)
= 0.8770-0.2177
= 0.6593
The answer is 20.6 hope this helps
Answer:
$49.18
Step-by-step explanation:
Dinner cost $38.95 before tax and tip are included.
Directions say to ADD 7% tip first so,
38.95 multiplied by 7%= 2.7265, Round up to $2.73
ADD $38.95 and $2.73 tax= $41.68
Now, multiply $41.68 by 18% to find the tip amount
$41.68 * 18%= 7.5024, Round to $7.50
ADD $41.68 and $7.50 to get answer: $49.18
