Answer:

-6/5   (This is Answer c)

Step-by-step explanation:

Re-writing this equation in standard form, we get:

25x^2 + 60x + 36 = 0.  The coefficients are a = 25, b = 60 and c = 36.

The discriminant, b^2 - 4ac, is 60^2 - 4(25)(36), or 3600 - 3600, or 0.

Because the discriminant is 0, we have two real, equal roots, corresponding to

       -b        -60

x  = ------ = ----------  = -6/5   (This is Answer c)

        2a       2(25)

Gnom [1K]

Answer:

d). 14 and 240

Step-by-step explanation:

According to the Question,

  • Given that,  The regression model involving 14 independent variables and 255 observations

We need to find out the numerator and denominator freedom degrees ,

k = 14 regression variable

= n - k - 1

= 255 - 14 - 1

= 240 residuals

df=14,240

  • Now The degree of freedom for F-critical is

F_{k,n-k-1}=F_{14,240}

So, The df of the numerator is 14 and df of the denominator is 240

If you can drive 340 miles in 5 hours, what is the unit rate? *<br> (2 Points)<br> Enter your answer
Marianna [84]
I believe it would be 68 miles per hour! To find the unit rate here you would divide miles by hours, or 340 by 5, which would give you 68.

What is the side length of a cube with a volume of 64 mm??<br>Cube V= 53​
galben [10]

Answer:

side length= 4 mm

Step-by-step explanation:

The explanation is pretty easy;

You know that to get the volume of a cube the formula is length times width times height. You also know that all sides of a cube are equal. so what multiplied by itself 3 times = 64?

That would be 4; 4 times 4 = 16 then 16 times 4 = 64

<em>Sorry if the explanation wasn't great:(</em>
