Answer:

A value for x.

Step-by-step explanation:

For example,

$y=-3x+6$

Substitute a random number for x to find the value of y, after which you'll have a point.

A manufacturer of cell phone screens is concerned because 12 percent of the screens manufactured using a previous process were r

astraxan [27]

Null hypothesis: There is no significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected .

Alternative hypothesis :There is a significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected .

Finally the null hypothesis will be rejected and we should accept the alternate hypothesis

Step-by-step explanation:

In the existing process the sample size and population was not known.,but the percentage of rejected screens were given as 12%.,but in the new process out of 100 screens only 6 are rejected

percentage of rejected screens using new process = 6÷ 100 ×100 = 6%

percentage of rejected screens using existing (old) process = 12%

so the new process is the effective one which reduces the rejection rate of screens., hence it is concluded that There is a significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected .

so the null hypothesis will be rejected and we should accept the alternate hypothesis

When 6 is subtracted from the square of a number, the result is 5 times the number. Find the POSITIVE solution.

valkas [14]

:) Brainliest pls??

Answer:

The positive solution is 6.

Step-by-step explanation:

x^2 - 6 = 5x (Subtract 5x from both sides)

x^2 -5x - 6 = 0 (We can factor this, so there is no need to use the quadratic formula)

(x - 6)(x + 1) = 0

If the product of the two terms is zero then either one being equal to zero will cause the whole expression to be zero.

The solutions are:

x - 6 = 0 (Add 6 to both sides)

x = 6

x + 1 = 0 (Subtract 1 from both sides)

x = -1

The positive solution is 6.

Solve this system of linear equations. Separate

Arte-miy333 [17]

Answer:

x = -7, y = -1

Step-by-step explanation:

Solve the following system:

{3 y - 2 x = 11 | (equation 1)

2 y + 3 x = -23 | (equation 2)

Swap equation 1 with equation 2:

{3 x + 2 y = -23 | (equation 1)

-(2 x) + 3 y = 11 | (equation 2)

Add 2/3 × (equation 1) to equation 2:

{3 x + 2 y = -23 | (equation 1)

0 x+(13 y)/3 = -13/3 | (equation 2)

Multiply equation 2 by 3/13:

{3 x + 2 y = -23 | (equation 1)

0 x+y = -1 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{3 x+0 y = -21 | (equation 1)

0 x+y = -1 | (equation 2)

Divide equation 1 by 3:

{x+0 y = -7 | (equation 1)

0 x+y = -1 | (equation 2)

Collect results:

Answer: x = -7, y = -1
