Help! how can i determine the range

djverab [1.8K]

Answer:

$[-1,\infty)$

Step-by-step explanation:

Remember that the range is the set of all y-values. Thus, since the minimum of the function is y=-1, then our range is $[-1,\infty)$ . In interval notation, we use brackets to show what's included and parentheses to show what's not included.

Using probability concepts, it is found that P(S and D) = 0.1275.

-----------------------

A probability is the number of desired outcomes divided by the number of desired outcomes.
In a standard deck, there are 52 cards.
Of those, 13 are spades, and 13 are diamond.

The probability of selecting a spade with the first card is 13/52. Then, there is a 13/51 probability of selecting a diamond with the second. The same is valid for diamond then space, which means that the probability is multiplied by 2. Thus, the desired probability is:

$P(S \cap D) = 2 \times \frac{13}{52} \times \frac{13}{51} = \frac{2\times 13 \times 13}{52 \times 51} = 0.1275$

Thus, P(S and D) = 0.1275.

Answer:

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Step-by-step explanation:

Before I answer these here are some good notes

If the inequality sign is < or > then the circle is going to be open

If the inequality sign is $\leq or\geq$ then the circle is going to be closed

If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right

If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Simplify by dividing 3/5 ÷ -4/9 1. -27/20 2. 27/20 3. -12/45 4. 12/45

kramer

Answer:

The answer to your question is -27/20

Step-by-step explanation:

Divide 3/5 ÷ - 4/9

Process

1.- Just multiply the numerator of the first fraction by the denominator of the second fraction.

3 x - 9 = -27

2.- Multiply the denominator of the first fraction by the numerator of the second fraction.

5 x 4 = 20

3.- Join both results

-27/20
