What is the solution to this system: 4x+9y=28 - 4x-y=-28

Mathematics
1 answer:
Degger [83]3 years ago
6 0

Answer:

x = 7

y = 0

Step-by-step explanation:

→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:

4x + 9y = 28

-4x - y = -28

__________

8y = 0

y = 0

<u>→Plug in 0 for y, into an equation:</u>

-4x - 0 = -28

-4x = -28

x = 7

What is the experamental probability that the coin lands on heads?
sammy [17]

Answer:

The experamental probability that the coin lands on head is 50 %

Step-by-step explanation:

Given:

Experiment:

A coin is Toss

Let the Sample Space be 'S' that is total number of outcomes for a coin has been tossed = { Head, Tail }

∴ n ( S ) =  2

Let A be the event of getting a Head on tossing a coin i.e  { Head }

∴ n( A ) = 1

Now,

\textrm{Probability} =\frac{\textrm{outcomes for the experiment}}{\textrm{total number of outcomes}}

Substituting the values we get

P(A) = \frac{n(A)}{n(S)} \\\\P(A) = \frac{1}{2} \\\\P(A) = 0.5\\\\P(A) = 50\%

The experamental probability that the coin lands on head is 50 %
