Answer:

Discrete

Step-by-step explanation:

The random variable that can be counted is known as discrete random variable. The number of pixels in cell phone display is a discrete variable. The reason is that the number of pixels is countable and can be represented by whole number. Also, the number of pixels are finite and can be counted so it is a discrete variable.

A line has a slope of -4 and passes through the point (0,5). Write the equation of this line in standard form. Be sure to expres

emmainna [20.7K]

Answer:

Final answer in standard form of the line is $4x+y=5$ .

Step-by-step explanation:

Given that slope of the lime m = -4

Now we need to find the equation of a line that has a slope of -4 and passes through the point (0,5). Write the equation of this line in standard form.

So plug the given slope m=-4 and the point (0,5) into point slope formula:

$y-y_1=m\left(x-x_1\right)$

$y-5=-4\left(x-0\right)$

$y-5=-4\left(x\right)$

$y-5=-4x$

$y=-4x+5$

$4x+y=5$

Hence final answer in standard form of the line is $4x+y=5$ .

Evaluate the function f(x) = 2x3 - 6x + 1 for f(-2).

erma4kov [3.2K]

Answer:

- 3

Step-by-step explanation:

$f(x) = 2 {x}^{3} - 6x + 1 \\ plugging \: x = - 2 \\ f( - 2) = 2( { - 2})^{3} - 6( - 2)+ 1 \\ = 2 \times ( - 8) + 12 + 1 \\ = - 16 + 13 \\ = - 3 \\ f( - 2) = - 3$

We have 500 grams of a 10% salt solution. How many grams of water must be added to dulite the solution to form a 4% solution. Sh

lys-0071 [83]

Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add

50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750

750 grams of water
