The product of any two numbers is composite ( true/false) and why?

Mathematics

Reptile [31]3 years ago

<u><em>FALSE.</em></u><em></em> 
A composite number is the opposite of a prime number. This is false because of the possibility of the following scenario:
The two numbers are 1 and a prime number.
This is because <em>one multiplied by any number is that number.</em> A prime number cannot become a composite number just because it is being multiplied by one. For example:
1 x 7 = 7 (prime) 
Hope this helps!

Solve by substitution:<br> y=5x-10 <br> y=3x-2
olganol [36]

Answer:

x=4 y=10

Step-by-step explanation:

y=5x-10

y=3x-2

We'll use the 2nd equation as a basis :

y=3x-2

3x-2=5x-10

0=2x-8

8=2x

4=x

We then use y=3x-2 to find y:

y=3(4)-2

y=12-2

y=10

A box contains 12 chocolates, 3 of which are white chocolate, 4 milk chocolate, and 5 dark chocolate. I am sharing the box with
Kay [80]

Answer:

Step-by-step explanation:

Given that a box contains 12 chocolates, 3 of which are white chocolate, 4 milk chocolate, and 5 dark chocolate.

a)  the chance that I draw a dark chocolate

b) Given that none of my friends draws a dark chocolate,  the chance that I draw a dark chocolate is

\frac{5}{9} since now all 5 dark chocolates would be there and total changed to 9 because 3 friends took 1 each.

c) All four drawn milk chocolates would be

\frac{4C4}{12C4} \\=\frac{1}{495}

d) the chance that the friend who gets to select first draws a dark chocolate and I draw a dark chocolate too

=P(first friend draws a dark chocolate) * P(I draw a dark chocolate)

When it comes to me chances are either there are 4 dark, or 3 dark, or 1 dark depending upon the other two friends drew black or not

= \frac{5}{12} *\frac{7}{11} *\frac{6}{11} +2(\frac{5}{12} *\frac{4}{11} *\frac{7}{11} ) +\frac{5}{12} *\frac{4}{11} *\frac{4}{11} \\= \frac{140+280+80}{1452} \\=\frac{500}{1452} \\=\frac{125}{363}

In this situation you would use cos 
which is adjacent over hypotenuse 
so I take the cos50 and have it equal to 17 / x
 cos(50)= 17/x 
which is the same as ...
17 divided by cos(50) =x 
x=26.44730506
which rounds to 26.45 
So your answer would be A)

I hope everything makes sense, enjoy! <span />
