Half the cards are even, 70/2 = 35 even cards.

The probability of picking an even card = 35/70, which reduces to 1/2

1+4=5 2+5=12 3+6=21 puzzle

wel

Answer:

The puzzle is first add the current two numbers and then add their sum to result obtained in previous step.

Step-by-step explanation:

1 + 4 = 5

2 + 5 = 12

12 is obtained by adding 2 + 5 = 7 and adding the result obtained in previous result which is 5 to 7

⇒ 7 + 5 = 12

Now, 3 + 6 = 21

21 is obtained by first adding 3 + 6 = 9 and the previous result obtained is 12

So adding 12 to 9 ⇒ 12 + 9 = 21

Hence, The puzzle is first add the current two numbers and then add their sum to result obtained in previous step.

What is the range of g(x) = - 2x + 3, if the domain is {-2, - 1,0, 1, 2}?

pshichka [43]

Answer:

{ - 1, 1, 7, 23 }

Step-by-step explanation:

To find the range substitute the values from the domain into g(x)

g(-2) = -2(- 2) + 3 = 4 + 3 = 7

g(- 10) = - 2(- 10) + 3 = 20 + 3 = 23

g(1) = - 2(1) + 3 = - 2 + 3 = 1

g(2) = - 2(2) + 3 = - 4 + 3 = - 1

Range is { - 1, 1, 7, 23 }

If you were solving a system of equations and you came to a statement like 1 = 3, what do you know about the solution to the sys

noname [10]

<h2>Key Ideas</h2>

Systems of equations

<h2>Solving the Question</h2>

When both sides of the equal sign are equal, there are infinite solutions.

When you are able to isolate the variable, there is only one solution.

When the equation states an untrue expression, there is no solution.

1=3 is an untrue fact. Therefore, there would be no solutions to the system.

<h2>Answer</h2>

There is no solution

On the graph shown, what is f(-1)? (5 points) The first segment joints the point negative three comma five exclusively and negat

tatiyna

ANSWER

$f( - 1) = 2$

EXPLANATION

The given function is a piecewise defined function.

$f( - 1)$
is the y-value that corresponds to
$x = - 1.$

To determine that y-value, we need to trace from
$x = - 1$
to where it meets the graph.

We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.

From the graph, we can see that this x-value corresponds to a y-value of
$2$

This implies that, when
$x = - 1,y = 2$

Therefore
$f( - 1) = 2$
See graph.
