<h2>Answer: <u>18</u></h2>

Given: the number is less than 20; three-factor pairs; each factor pair individually adds up to 19, 11, and 9

Solve for her number.

Step-by-step explanation:

If you think about it for a little bit, you will eventually find that 18 + 1 = 19 and 18 × 1 = 18 which is less than 20.

Then we know 18 has 2 more factor pairs : 9 × 2 and 6 × 3 which add up to 11 and 9.

Therefore our answer is: 18

18 × 1

9 × 2

6 × 3

The trick is to pick the largest sum of one-factor pair (19 in this question) and then choose the number below it.

What is the equation of a line that is parallel to x=7/5x+6 and that passes through the point (2,-6)

const2013 [10]

The answer is below
we're given
$y = \frac{7}{5} x + 6$
we need to convert to point slope form with our slope and point given
point slope form is
$y - y1 = m(x - x1)$
so we fill in slope and our point

$y + 6 = \frac{7}{5} (x - 2)$
we simplify the left side and get
$y + 6 = \frac{7}{5} x - \frac{14}{5}$
then we subtract 6 from the left and get
this as our final answer
$y = \frac{7}{5} x - \frac{44}{5}$

Find the lengths, if needed round to the nearest tenth

Elis [28]

Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle that is made up of 2 right angle triangle.

To determine y, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

15² = y² + 12²

225 = y² + 144

y² = 225 - 144 = 81

y = √81 = 9

To determine z,

20² = z² + 12²

400 = z² + 144

z² = 400 - 144 = 256

z = √256 = 16

3. A manufacturing process produces integrated circuit chips. Over the long run, the fraction of bad chips produced by the proce

AnnyKZ [126]

Answer:

0.812 = 81.2% probability that a randomly chosen chip will pass the test

Step-by-step explanation:

Over the long run, the fraction of bad chips produced by the process is 20%.

So 100 - 20 = 80% are good.

All good chips pass the test, while 6% of the bad chips(20%) also pass.

a) (4 points) What is the probability that a randomly chosen chip will pass the test

$p = 0.8 + 0.06*0.2 = 0.812$

0.812 = 81.2% probability that a randomly chosen chip will pass the test
