Answer: she must complete 4 levels to have a point fewer than 20
Step-by-step explanation:
Given the following :
Starting point = 100 points
Passing a level = - 8 points
Catching a flower = - 3 points
Suppose Tina catches 6 flowers per level
Number of levels she must complete to have fewer Than 20 points
Total number of points lost per level:
Catching 6 flowers = -(6 × 3)
Passing the level = - 8
= - 18 + - 8 = - 26 points
Number of levels she must complete to have < 20
Let number of levels = y
Starting points - (26 × number of levels) < 20
100 - (26y) < 20
100 - 26y < 20
-26y < 20 - 100
-26y < - 80
y > 80/26
y > 3.07
Hence she must complete 4 levels to have a point fewer than 20

Answer:
Ans 1 is correct.
Step-by-step explanation:
We have given that,
p=0.85,
n=20.
we know that
1-P(x=1)=1-(0.85×0.15^19)=0.999
Ans 1 is correct.
1.5x+x=1380
2.5x=1380
x=552 miles
A is the solution.
P-.15p this is the expression for cost after discount
and its just .15p for just the discount
