Answer:
x = 0
Step-by-step explanation:
If one were to fold this figure in half over the line x = 0, then one would end up with a single figure, with no overhang. Hence x = 0 is the line of symmetry. Note; x = 0, can also be called the y-axis.
Answer:
See attached figure with table filled in.

Answer:
81.85% of days would you expect the store to sell from 33 to 42 pairs of shoes
Step-by-step explanation:
The mean number of pairs of shoes sold by a shoe store is 36
Standard deviation =
We are supposed to find percent of days would you expect the store to sell from 33 to 42 pairs of shoes i.e.P(33<x<42)
Formula :
At x = 33
Z=-1
Refer the z table for p value
p =0.1587
At x = 42
Z=2
Refer the z table for p value
p =0.9772
So,P(33<x<42)=P(x<42)-P(x<33)=0.9772-0.1587=0.8185
Hence 81.85% of days would you expect the store to sell from 33 to 42 pairs of shoes
Answer:
12.3 feet
Step-by-step explanation:
Given
<P = 90 degrees
<N = 59 degrees
PN = 7.4 feet
Required
OP
NO = hypotenuse
OP = adjacent
PN = opposite = 7.4
Using SoH CAH TOA identity
tan <O =PN/OP
tan (180-149) = 7.4/OP
tan 31 = 7.4/OP
OP = 7.4/tan 31
OP = 7.4/0.600
OP = 12.3 feet (to the nearest tenth)
