Step-by-step explanation: To find the surface area for a pyramid, we can use this formula: $A=lw+l\sqrt{(\frac{w}{2})^2 } +h^2+w\sqrt{(\frac{l}{y} } )^2+h^2$

Solution: $10\times10+10\times\sqrt{(\frac{10}{2} } )^2+18^2+10\times\sqrt{(\frac{10}{2} } )^2+18^2=423.63$

Let me know if you have any questions.

Passes through (2,2), slope = 3

nikdorinn [45]

Answer:

y - 2 = 3(x - 2)

Step-by-step explanation:

Hello!

Please consider using the point-slope formula for the equation of a straight line, because in this case it's the easiest way to go.

(2,2) is one point on the line, and the slope is m = -3.

Thus, y - k = m(x - h) becomes y - 2 = 3(x - 2).

P(X=x). 0.05 0.09 0.03 0.42 0.41

b. Scores mg, Y 1. 2. 3. 4. 5

P(Y=y). 0.04. 0.1. 0.12 0.46 .28

c. probability that a randomly selected senior executive will report a job satisfaction score of 4 or 5.
