Standard form 3x+12y=-8 in slope-intercep form​

Mathematics
1 answer:
Helga [31]3 years ago
4 0

Answer:

y = -\frac{1}{4} x-\frac{2}{3}

Step-by-step explanation:

slope intercept form is y = mx + b

You need to solve the equation for y. First, subtract 3x from both sides since it is a positive 3x.

3x - 3x + 12y = -8 - 3x

rewrite the equation

12y = -3x - 8

divide all terms by 12

12y/12 = -3x/12 -8/12

Simplify the fractions

y = -\frac{1}{4} x-\frac{2}{3}

Nadusha1986 [10]

Answer:

24 miles west.

Step-by-step explanation:

26m travelled north = 26m

24m travelled west = 24m

24 + 26 = 50m

Antonio would have to drive 24 miles west from the 26 miles he drove north to determine that he is 50 miles from where he started. Antonio drove 24 miles west.

malfutka [58]

Answer:

Hello some parts of your question is missing below is the missing part

answer : A) p-value =  0.0019 ,

The level of significance ( 0.05 ) > p-value ( 0.0019 )

B) There is no dependence between the two ratings

Step-by-step explanation:

A) using a 0.05 level of significance and test for independence of the quality of management

Test statistic : X^{2}  ∑ ( Oi - Ei )^2 / Ei

= [(40-35)^2 / 35 ] +  [(25-24.5)^2 / 24.5 ] +  [(5-10.5)^2 / 10.5]  +  [(35-40)^2 / 40]  +  [(35-28)^2 / 28]  +  [(10-12)^2 / 12]  +   [ (25-25)^2 / 25 ]  +  [(10-17.5)^2 / 17.5 ]  + [(15-7.5)^2 / 7.5]  =  17.03  

p-value = 0.0019

Df = 4  ,

The level of significance ( 0.05 ) > p-value ( 0.0019 )

B) There is no dependence between the two ratings

A cylinder has volume 45 pie and radius 3. What is its height?
liraira [26]

Answer:

5 units

Step-by-step explanation:

The <u>volume of the cylinder</u> is the area of the circle multiplied by it's height. Therefore, the volume of the cylinder is πr² × h, which when simplified, gives us πr²h. Let's substitute the volume and the radius in the formula to find the height.

⇒ πr²h = Volume of cylinder

⇒ (π)(3²)(h) = 45π

Now, simplify the equation to evaluate the area of the cylinder.

⇒ (π)(3²)(h)/(3²)(π) = 45π/(3²)(π)

⇒ (h) = 45π/(9)(π) = 45/(9) = 5 units
