Hmm
that is a true statement, the product of any 2 mixed numbers between 4 and 5, will be between 16 and 25

we can show that it is true by testing the bounds
if the number is 4 and the other is 4, then it is 16
we aren't allowed to do 4 since it isn't mixed and it equals 4
that is the lower bbound

if the numbes 5 and 5 are used, then it is 25
we arene't allowed to use 5 since it isn't mixed and it equals 5

so the product of any 2 numbers between 4 and 5 will be between 16 and 25

so pick any random one

4 and 3/4 times 4 and 5/323

Convert 7.7km into miles if 1.6 km = 1 mile
Lemur [1.5K]
This is a simple equation.  

The equation is y = 1.6x  with y being the miles and x being the kilometers.

Lets plug the kilometers in.

Y=1.6(7.7)

1.6 *  7.7 = 12.32

12.32 miles is  equal to 7.7 kilometers

HOWEVER

There are about .6 miles in a kilometer, so if you typed this wrong I don't know.  

It is still the same concept.

Y = .6x

Y = .6(7.7)

.6 * 7.7 =  4.8

In this case there are 4.8 miles in 7.7 kilometers

using a standard 52-card deck, find the following probabilities. assume the cards are drawn without replacement. Find the probab
Mamont248 [21]

Answer:

1/169

Step-by-step explanation:

The probability of drawing a 3 in a 52 card deck is 4/52 which can be simplified to 1/13.

The probability of then drawing a jack is 4/52, also simplified to 1/13. It doesn't matter of you want to put jack or 3 first, there are 4 of each in a deck.

1/13*1/13=1/169

Evaluate the function for an input value of 3. f(x)= −4x 2 −3x−5
Serhud [2]

Answer:

- 50

Step-by-step explanation:

x = 3

f ( x ) = - 4x^2 - 3x - 5

f ( 3 )

= - 4 ( 3 )^2 - 3 ( 3 ) - 5

= - 4 ( 9 ) - 3 ( 3 ) - 5

= - 36 - 9 - 5

= - 50
