Answer: the top right
Step-by-step explanation:
The time for this z-score is 3.28.
The formula for z-scores is
z = (X-μ)/σ
Using our information, we have
-1.2 = (X-4.6)/1.1
Multiply both sides by 1.1:
-1.2(1.1) = X - 4.6
-1.32 = X - 4.6
Add 4.6 to both sides:
-1.32 + 4.6 = X - 4.6 + 4.6
3.28 = X
Answer:
1cm
Step-by-step explanation:
from the scale we know that
1cm on the map is equal to 300cms on the ground
Below I have made a table and used the unitary method.
Distance on Map Distance on ground
1cm 300cm
let width be = x width = 3m = 300cm
hence
width = ( 1 ×300)/ 300 = 1cm
Hope this helps
