Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Sound quality test = every fifth siren

Mechanical quality = every 8th siren

Daily output = 350 siren

Percentage tested for mechanical quality :

Number of siren tested for mechanical quality / total output

Number of siren tested for mechanical quality = (350 / 8) = 43. 75

= 43 sirens

% tested for mechanical quality :

(43 / 350) * 100%

0.12285 × 100%

= 12.29%

What percent is tested for both types of quality at the same time?

Number tested for both types simultaneously = 8

% tested for both types of quality :

(8 / 350) * 100%

0.0228571 × 100%

= 2.28571%

= 2.29%

Functions f(x) and g(x) are shown below:
kondor19780726 [428]
We look for the minimum of each function.
 For f (x) = 3x2 + 12x + 16:
 We derive the function:
 f '(x) = 6x + 12
 We match zero:
 6x + 12 = 0
 We clear the value of x:
 x = -12/6
 x = -2
 We substitute the value of x in the equation:
 f (-2) = 3 * (- 2) ^ 2 + 12 * (- 2) + 16
 f (-2) = 4
 For g (x) = 2sin(x-pi):
 From the graph we observe that the minimum value of the function is:
 y = -2
 Answer:
 
A function that has the smallest minimum y-value is:
 
y = -2

How do you divide big numbers?<br>like for example, 2,673 ÷ 486?
Dahasolnce [82]
The easiest way I know is to multiply the divisor by different numbers to see how many times it will go into the dividend. multiplying 486 by 2 or three and seeing which one gets closest.
