Answer:
Hence,
a) The probability that the sample average would be less than 90 pounds is 0.0210.
b) The probability that the sample average would be between 98 and 105 pounds is 0.5045.
c) The probability that the sample average would be less than 112 pounds is 0.9935.
d) The probability that the sample average would be between 93 and 96 pounds is 0.1341.
Step-by-step explanation:
a)
= P(Z < -2.03) = 0.0210
b )
= P(-0.39 < Z < 1.05) = 0.5045
c )
= P(Z < 2.49) = 0.9935
d )
= P( -1.42 < Z < -0.8 )
= 0.2119 - 0.0778 = 0.1341
Answer:
It is linear
Step-by-step explanation:
If your graph all the points you can see they would be linear
(the equation for the line would be y=3x+2 btw if you need that)

Answer:
1 cm = 5 meters
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
60 meters / 12 centimetres
5 meters / 1 centimetres
