Mathematics
1 answer:
PtichkaEL [24]3 years ago
3 0

Answer:

1536 in^2

Step-by-step explanation:

This is basically asking for the surface area so knowing that is a cube all the sides are equal so one side would be 16(16) which is 256 in ^2.  The knowing that there is 6 sides you would multiply it by 6 which is 256(6)= 1536^2

Why is 1 neither prime nor a composite number?
Nadya [2.5K]

Answer:

1 is neither prime nor a composite number because it only has 1 divisor, 1 and 1, and it doesn't have more than 2 integral divisors, like stated, it only has 1. So it falls in neither category.

kotegsom [21]

Answer:

draw a number line from 66 to 81

make your minimum 67

lower quartile should be on 70

the median on 77

upper quartile and maximum on 80

(note that your upper quartile and maximum is both on 80 so there won't be an extension as you normally would see on a box plot)

You can search up "box plot" and go on images to see what i mean

(copy and pasted from your last post!)

Step-by-step explanation:

I can probably help on part 4 and send a sketch but I currently can't use my phone to send a pic and I am currently on my desktop :'(

The notation f:S→T denotes that f is a function, also called a map , defined on all of a set S and whose outputs lie in a set T
AnnyKZ [126]

Answer:

There are many. Two examples are

f(x) = x, \\f(x) = x^3

Step-by-step explanation:

There are many examples. The simplest is

1 -

f(x) = x

It is trivial that

\text{if \,\,\,\,}  f(x) = f(y) \,\,\,\,\,\text{then} \,\,\,\,\, x=y

2 -

f(x) = x^3

That function is injective as well.

\text{if \,\,\,\,}  x^3 = y^3 \,\,\,\,\,\text{then} \,\,\,\,\, x=y

An example of a function that is NOT injective is

f(x) = x^2

Notice that

f(-2) = (-2)^2 = 2^2 = 4

A train has 6 identical passenger cars that are each 18 m long.
Gnesinka [82]

Answer:

59m

Step-by-step explanation:

No of passenger cars in the train = 6

length of each passenger cars = 18m

total length of 6 passenger cars = 18 * 6 = 108 m

length of caboose = 10m

total length of train when caboose is included = 108 m + 10 m = 118m

_____________________________________________

Let the length of truck be X m

given that length of train is twice of length of truck = 2*X

but length of train as found above is 118 m

this implies

2X = 118

X = 118/2 = 59m

Therefore length of truck is 59m
