Answer:Simplifying

a = 1 + 0.3333333333b + 1.666666667c

Step-by-step explanation:

Simplifying

3a + -1b + -5c = 3

Solving

3a + -1b + -5c = 3

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add 'b' to each side of the equation.

3a + -1b + b + -5c = 3 + b

Combine like terms: -1b + b = 0

3a + 0 + -5c = 3 + b

3a + -5c = 3 + b

Add '5c' to each side of the equation.

3a + -5c + 5c = 3 + b + 5c

Combine like terms: -5c + 5c = 0

3a + 0 = 3 + b + 5c

3a = 3 + b + 5c

Divide each side by '3'.

a = 1 + 0.3333333333b + 1.666666667c

Simplifying

a = 1 + 0.3333333333b + 1.666666667c

The circle below is centered at the point (4,3) and has a radius length 5. What is its equation

Crazy boy [7]

The equation of a circle centred at point (m,n) and radius r is given by

<span>(x-m)² + (y-n)² = r²
</span>-------------------------------------------------------------
Centre = (4,3)
radius = 5

Equation:
(x - 4)² + (y - 3)² = 5²
⇒ x² - 8x + 16 + y² - 6y + 9 = 25
⇒ x² + y² - 8x - 6y + 25 = 25
⇒ x² + y² - 8x - 6y = 0

The equation of the circle is x² + y² - 8x - 6y = 0

Hope it helps!

The number of minutes that Samantha waits to catch the bus is uniformly distributed between 0 and 15 minutes. What is the probab

Maslowich

Answer:

option d. 30%

Step-by-step explanation:

Data provided in the question:

$a=0$

$b=15$

Now,

The probability density function of the uniform distribution is given as:

$f(x)=\frac{1}{15-0}$

$f(x)=\frac{1}{15}, 0$

Therefore,

The required probability will be

$P(X$

= 0.3 × 100%

= 30%

Hence,

The answer is option d. 30%

I need help on this

Draw a vertical line at the number 4 on your x axis positive side which is x=4

Then anything on the left of this line you just created at x=4 will be less than 4. But since your inequality is x less than/equal to 4 it includes 4 as well.

Determine which ordered pairs are solutions to the equation 3x+7y=21

mafiozo [28]

Answer:

(0,3) and (7,0) are solutions.

Step-by-step explanation:

In a pair of coordinates, they are always listed as (x,y). Since this is the case, you plug in each coordinate to their respective places.

For (0,3)

3(0) + 7(3) = 21

0 + 21 = 21

For (7,0)

3(7) + 7(0) = 21

21 + 0 = 21

To double check that (1,2) isn't a solution:

3(1) + 7(2) = 21

3 + 14 = 21

17 = 21 X

This doesn't work.

Marking as Brainliest is much appreciated.
