If the average of defective items is 0.038% then we will get 3 items being defective from 8000 items which are checked.

Given that the average of finding a defective item is 0.038%.

We are required to find the number if defective items that we will find from 8000 items.

Percentage is the number or ratio that is expressed in terms of 100. It is expressed as %.

Average of defective items=0.038%

Number of items checked=8000

Number of defective items that we will get=8000*0.038/100

=304.100

=3.04

Approximately 3 items.

Hence if the average of defective items is 0.038% then we will get 3 items being defective from 8000 items which are checked.

Factorization of <br>x²+6x+5​
crimeas [40]

Answer:

(x +1) (x + 5)

Step-by-step explanation:

Factorization of x²+6x+5​

To factorise this quadratic expression we'll find 2  factors of 5 that when added gives the coefficient of x which is

Factors = +1 and +5

Sum = +6, product = +5

Rewriting equation

x² + x + 5x + 5

Factorising

x ( x +1) +5 ( x + 1)

(x +1) (x + 5)

20 POINTS AND BRAINLIEST!!!!!!!!!!!!!!!!!!
wolverine [178]
Look for points with whole number coefficients.  (2,4) is such a point; (0,1) is another.  To find points on the graph of the inverse of this function, all we have to do in this case is to reverse the order of the coefficients, so 

(2,4) becomes (4,2) and (0,1) becomes (1,0).  Only (4,2) is included in the list of answer choices, above, so the correct answer is (4,2).

What is the equation of the line parallel to 3x+2y= -4 that goes through the point (4,-1)
sertanlavr [38]

Answer:

y = (-3/2)x + 7

Step-by-step explanation:

3x + 2y = -4 (rearrange to slope intercept form y = mx + b)

2y = -3x - 4

y = (-3/2) x - 2

comparing this to the general form of a linear equation : y = mx + b

we see that slope of this line (and every line that is parallel to this line),

m = -3/2

if we sub this back in to the general form, we get:

y = (-3/2)x + b

We are still missing the value of b. To find this, we are given that the point (4,1) lies on the line. We simply substitute this back into the equation and solve for b.

1 = (-3/2)4 + b

1 = -6 + b

b = 7

substituting this back into the equation:

y = (-3/2)x + 7

The mean can be found by adding the two numbers and dividing by 2

let the second number be y

(x + y)/2 = 1/2x + 1

solve for y

multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2

ANSWER: the second number is 2
