uysha [10]

The machine was operated for  4.5 hours

A machine uses gasoline at a rate of 1/5 gallon per hour

The number of hours it will take the machine to use 9/10 gallon can be calculated as follows

1/5 = 1

9/10= x

cross multiply

1/5x= 9/10

0.2x= 0.9

x= 0.9/0.2

x= 4.5

Hence the machine was operated for 4.5 hours

A one compartment vertical file is to be constructed by bending the long side of an 8 in 8 in. by 10 10 in. sheet of plastic alo
charle [14.2K]
Th long side of the plastic sheet is bent into a U shape.
Therefore the dimensions of the file holder are 8, h, and (10 - 2h) as shown in the figure. 

The volume of the file holder is
V = 8*h*(10 - 2h) = 80h - 16h²
To maximize V, V'(h) = 0.
That is,
80 - 32 h = 0 
h = 80/32 = 2.5 in

V''(h) = -32 guarantees that V is maximum because V'' <0.
Maximum V = 80*(2.5) - 16*(2.5)² = 100 in³

Answer: h = 2.5 in

Your friend tells you that the proportion of active Major League Baseball players who have a batting average greater than .300 i
marin [14]

Answer:

Null hypothesis: The proportion of active Major League Baseball players who have a batting average greater than 0.300 is 0.51 (p equals 0.51).

Alternate hypothesis: The proportion of active Major League Baseball players who have a batting average greater than 0.300 is not 0.51 (p not equals 0.51).

Step-by-step explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
