Determine the slope of the line 5x-3y-12=0

Shtirlitz [24]

Answer:

slope of the line=5/3

Step-by-step explanation:

The general slope-intercept form of a line is given by,

y=mx+c

where, m is the slope of the line and c is the y-intercept

$5x - 3y - 12 = 0$

$- 3y = 12 - 5x$

$3y = - (12 - 5x)$

$3y = 5x - 12$

$y = \frac{5x - 12}{3} = \frac{5}{3} x - 4$

Here, m=5/3

Which of the following random variables is not discrete?

Ilia_Sergeevich [38]

Answer:

b) The annual rainfall in a city

Step-by-step explanation:

Remember, a discrete variable is one that can only take a finite number of values between any two values of a characteristic and a continuous variable is one that can take an infinite number of values between any two values of a characteristic.

a) Observe that the variable x='classes taken in one semester' can take the values 0,1,2,...,n.

Then the variable x is discrete

b) Observe that the variable x='annual rainfall in a city' can take the values 2in, 1.6in, 5.1 in, 0.1in

Then, the variable x can be take a infinite number of values between two number. So x isn't a discrete variable.

c) The variable x='attendance at a football game' can take the values 3000,5000... n. And never will be a decimal number because There cannot be a personal decimal number. Therefore, x is a discrete variable.

d) The variable x='patients treated at an emergency room in a day' can take the values 1,2,3,...,n. And never will be a decimal number because There cannot be a personal decimal number. Therefore, x is a discrete variable.

Orlando bought a new couch for $2,904, using the furniture store's finance plan. He will pay $121 a month for 24 months. Which e

kotegsom [21]

So we want to know how much Orlando owes, here's the answer:

Since he pays 121$ every month, the formula would be this:

$y = 2,904 - 121x$ , if we consider x = months.

So the answer is B, $y = 2,904 - 121x$

Hope this helped! c:

Lynn has a watering can that holds 32 cups of water, and she fills it half full. Then she waters her 21 plants so that each plan

notka56 [123]

Amount of water Lynn's watering can can hold = 32 cups

As she fills it half full means she fills it with 32/2= 16 cups

Number of plants watered from 16 cups = 21 plants

As, each plant gets same amount of water, so each plant gets =

$\frac{16}{21}$ cups or 0.76 cups of water

Hence, each plant gets 0.76 cups of water.

Use the double angle identity:

$\sin^2\dfrac\pi{12}=\dfrac{1-\cos\frac\pi6}2$

Then $\cos\dfrac\pi6=\dfrac{\sqrt3}2$ , so you get

$\sin^2\dfrac\pi{12}=\dfrac{2-\sqrt3}4$
