Mathematics
1 answer:
Sunny_sXe [5.5K]2 years ago
5 0

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

Relative frequency = frequency / total frequency

Total frequency = 389+335+975+351+72 = 2122

Response ________ Frequency __ R/ frequency

Never ____________ 389 _ 389/2122 = 0.180

Rarely ____________ 335 _ 335/2122 = 0.158

Sometimes _________975 _975/2122 = 0.459

Most of the time _____ 351 _ 351/2122 = 0.165

Always ____________ 72 __ 72/2122 = 0.034

What is the maximum number of possible extreme values for the function,<br> f(x) = х2 -7x – 6?
timama [110]

Answer:

Only one extreme value of f(x) is possible.

Step-by-step explanation:

We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)

Now. the condition for extreme values of f(x) is \frac{df(x)}{dx} =0

Hence, differentiating both sides of equation (1) with respect to x, we get

\frac{df(x)}{dx} = 2x -7 = 0

⇒ x = 3.5.

So there is only one value of x for which f(x) has extreme value which is x = 3.5.

Therefore, only one extreme value of the given function is possible. (Answer)

BC = 6, EF = 12 Based on the given information, choose the similarity statement that you would use to say ABC~DEF. If you could
vovangra [49]

Answer:

The answer is "NOT"

Step-by-step explanation:

  • To demonstrate a similar statement we want to have yet another side or some other angle, however, the third section is not proportional.  
  • Its sides were equivalent in proportions (yeah sure they are) + corner by the by is not given.
  • There is no triangle angle provided so, that we can not enforce the SAS argument.  
  • It is not evidence of similarity between ABC ≈DEF.

Answer:

This is a direct variation where the constant of variation is 5/9

Step-by-step explanation:

The equation for direct variation is y = kx

5x-9y =0

Lets try to get this equation in the above form

Add 9y to each side

5x-9y +9y = 9y

5x = 9y

Divide each side by 9

5/9 x = 9y/9

5/9x = y

This is in the form y = k x where k =5/9

“Find the values of x and y when the smaller triangle here has the given area! “
natita [175]
Answer:

I think it’s 48 cm

Step-by-step explanation:

Area is length x width so 8 x 12 is 96 and since it is twice the slice of the smaller triangle, 96 divided by 2 is 48
