C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = , cos45° =
, thus
sin60° = =
=
( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp =
Now consider the right triangle on the right, using the cosine ratio
cos45° = =
=
( cross- multiply )
x = ×
=
→ C
Answer:
Step-by-step explanation:
Given that the number of orders received daily by an online vendor of used CDs (say X) is normally distributed with mean 270 and standard deviation 16.
X is N(270, 16)
To find percentage of days will the company have to hire extra help or pay overtime, we can find probability using std normal table
X>302 means
P(Z>2) = 0.25
Thus 25% of days will the company have to hire extra help or pay overtime
