Answer:
A. h(x)= -3 - 10.5
Step-by-step explanation:
Plug in the x-values from the table into each function. If you get the y-values that appear in the table, that is the correct function.
Answer:
79.77%
Step-by-step explanation:
P(X≥120) = normalcdf(120,1e99,130,12) = 0.7976716754 ≈ 0.7977 = 79.77%
Therefore, about 79.77% of operations last at least 120 minutes
Answer:
35/4 or 8,3/4
Step-by-step explanation:
Flip the second fraction and multiply.
It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6
49/12
Just mulitply the top and the bottom across.
7*7/4*3
49/12
