Answer:
Domain: x>0
Y is all reals, so infinity.
Answer:
There was a reflection about the x-axis and a vertical stretch.
Step-by-step explanation:
This is a hyperbola.
Volume of an iceberg = 7685 cubic feet
Since, density of ice = 0.917
We have to determine the mass of the ice.
Since density =
Since the unit of density is in , first we will convert the density unit in kilogram.
Since, 1 kilogram = 1000 gram
Therefore, density =
= 0.000917
Since, the density unit is in cubic centimeter. We will convert it into cubic feet.
1 cubic centimeter = 0.00003531466 cubic feet
Therefore, 0.000917 = 0.000917 x 0.00003531466
= 0.0000000323 .
Now, mass =
= 0.0000000323 7685
= 0.000248
=0.00025 .
Therefore, the mass of ice is 0.00025 .

Answer:
0.4246
Step-by-step explanation:
Given data:
mean (<em> u</em> ) = 15 inches
std ( б )= 6 inches
sample size( n ) = 46
<em>u</em>x = mean sample length
Determine the probability that x within 0.5 inch of the claimed population mean
<em>u</em>x = <em>u = </em>15
бx = б/ √ 46 = 6 /√ 46 = 6 / 6.78 = 0.88
Hence the P( 14.5 < x < 15.5 )
= P ( [14.5 - 15 / 0.88 ] < z < (15.5 - 15) / 0.88) )
= P ( -0.5682 < z < 0.5682 )
= P ( z < 0.5682 ) - P ( z < -0.5682 )
= 0.7123 - 0.2877 ( from Z table )
= 0.4246
