Answer:
The volume of fish tank is 
Step-by-step explanation:
Area of Base of fish tank = 
We are given that A fish tank has a base, B, with an area, in square inches, modeled by
So, 
Height of tank = x+3
Volume of tank = 
So, Volume of tank =
Volume of Tank =
Hence The volume of fish tank is
Y=2x+6 We know the y intercept is +6 so we still can’t eliminate any of the options. We know it can’t be 1/3x or 1/2x because the y value is greater than the x value. (6)(2)+6=18
Answer:
2 pieces of 3/8 yard.
Step-by-step explanation:
They tell us that originally the fabric measures 3/4 of a yard and then it is cut and remains pieces of 3/8 of a yard, so we must know how many pieces could have been cut so that they will be this size, therefore we must divide:
3/4 / (3/8) = 2
Which means there are 2 pieces of 3/8 yard.
Answer:
0.78814
Step-by-step explanation:
We solve using z score
z = (x-μ)/σ, where
x is the raw score = 4.0 inches
μ is the population mean = 4.4 inches
σ is the population standard deviation = 0.5 inches
z = 4.0 - 4.4/0.5
z = -0.8
Probability value from Z-Table:
P(x<4.0) = 0.21186
P(x>4.0) = 1 - P(x<4.0)
= 1 - 2.1186
= 0.78814
The probability that the rod you chose will be greater than 4.0 inches is 0.78814.
