Answer:

13.25km

Step-by-step explanation:

25 Litres = 331.25km

1 Litre =

$\frac{331.25}{25} \\ = 13.25km$

Please answer right, I've been stuck on this test for an hour.

AlladinOne [14]

Answer:

D

Step-by-step explanation:

f(x) has a horizontal asymptote of -4 while g(x) has horizontal asymptote of zero, in both functions, y is closer to infinity as x is closer to negative infinity,

A and B are definitely incorrect

while x gets closer to infinity, in f(x) y gets closer to -4, while in g(x) y gets closer to 0, thus they have a different end behavior as x approaches infinity

So, C is wrong, since it says that they have the same end behavior as x approaches infinity

Thus, D is correct

A box is to be constructed from a sheet of cardboard that is 20 cm by 50 cm by cutting out squares of length x by x from each co

Nezavi [6.7K]

We are given the dimensions of the box:

l = 50 cm

w = 20 cm

We know that the volume of a box is:

V = l w h

where h = x

However since x cuts is made on both all sides of the box, therefore the new dimensions would be:

V = (l – 2x) (w – 2x) x

V = (50 – 2x) (20 – 2x) x

V = 1000x – 100x^2 – 40x^2 + 4x^3

V = 4x^3 – 140x^2 + 1000x

To get the maxima value, we get the 1st derivative of the function then set dV/dx = 0 to solve for x:

dV / dx = 12x^2 – 280x + 1000

12x^2 – 280x + 1000 = 0

Transpose 1000 to the right side and divide everything by 12:

x^2 – (280/12)x = -(1000/12)

Completing the square:

x^2 – (280/12)x + (78400/576) = -(1000/12) + (78400/576)

[x – (280/24)]^2 = 52.78

x – (280/24) = ±7.26

x = (280/24) ± 7.26

x = 4.40, 18.93

x cannot be 18.93 since this would result in a negative value of 20 – 2x, therefore:

x = 4.40 cm

Calculating for the volume:

V = (50 – 2*4.4) (20 – 2*4.4) (4.4)

V = 2030.34 cm^3

Suppose U.S. consumers 21 years and older consumed 26.8 gallons of beer and cider per person during 2017. A distributor in Milwa

Kruka [31]

Answer:

d) Conclude that the population mean annual consumption of beer and cider in Milwaukee is greater than 26.8 gallons and hence higher than throughout the United States.

Step-by-step explanation:

We have a hypothesis test about the true mean consumptionof beer and cider for U.S. 21+ years-old consumers with the following null and alternative hypothesis:

$H_0: \mu=26.8\\\\H_a:\mu> 26.8$

The result of the test is to reject the null hypothesis.

This means that there is evidence to support the claim that beer and cider consumption was higher than the national average in Milwaukee in 2017 .
