The graph of the function $f(x)=-\sqrt{x}$ is the first graph which is attached below.

Step-by-step explanation:

The function is $f(x)=-\sqrt{x}$

To graph the function, we need to know the domain and range of the function.

The domain is found by substituting the values for x.

Thus, the domain is $x\geq 0$

The range of the function is determined as $y\leq 0$ . Since, substituting the values of x we get the corresponding y-value which lies in the interval $(-\infty, 0]$ .

The graph of the function $f(x)=-\sqrt{x}$ is the first graph which is attached below.

Leona has 4 nickels, 6 pennies, 4 dimes, 2 quarters in a change purse. Leona lets her little sister Daisy pick a coin at random.

seropon [69]

There are 6 coins that are each worth more than 5 cents. In total, there are 16 coins. So, the probability is 5/16.

Good luck!

Suppose a researcher compiled a data set consisting of the following variables for a sample of 100 retired men. For each variabl

kondaur [170]

Answer:

a) Discrete Variable

b) Discrete Variable

c) Discrete Variable

d) Continuous Variable

Step-by-step explanation:

We have to identify the given variable as discrete r continuous.

Discrete Variables:

They are expressed in whole numbers.
They are counted not measured.
They cannot take any value within an interval.

Continuous Variables:

They are expressed in decimal numbers.
They are measured not counted.
They cannot take any value within an interval.

a) The number of countries ever visited

Since number of countries will always be expressed in whole numbers and not decimals. Also, they will always be counted and not measured. Thus, it is a discrete variable.

b) The number of sons

Since number of sons will always be expressed in whole numbers and not decimals. Also, they will always be counted and not measured. Thus, it is a discrete variable.

c) Shoe size

Shoe size are expressed in whole number. The underlying measure is length of feet which is a continuous variable but shoe size are always given in whole number. Thus, they cannot take any value within an interval. Thus, it is a discrete variable.

d) Body temperature

Body temperature can be expressed in decimal. A Body temperature of 42.5 makes sense. Thus, they can take any value within an interval. Also, it is measured not counted. Thus, it is a discrete variable.

Find the slope of the line perpendicular to the line containing (0,0) and (-1,4).

Tema [17]

Answer:

Hello, Have a good day

Step-by-step explanation:

The slope of the perpendicular line is the opposite sign and the inverse of the original line's slope.

(-1,-2) and (0,0).

slope = (0 - -2)/(0 - -1) = 2/1

So ,inverse and opposite would be -1/2

A parallel line has the same slope with a different y intercept

-2 = (-1/2)(-1) + b

-2 = 1/2 + b

b = -5/2

So, same slope, different b (y intercept) for a parallel line.
