Please help me determine the equation of the line in slope intercept form and show all work. A line that is perpendicular to the
Airida [17]

Answer:

y=-2x+160

Step by Step:

The equation of a line can be determined using the point slope formula:

y-y1=m (x-x1)

To make a substitution, we must ensure we have the correct information. The question gives:

y1=60

x1=50

y=1/2x+10 This is the formula of a line that is perpendicular to the one we are trying to find.

It tells us that the gradient of the perpendicular line is 1/2. The gradient of the line we are trying to find can be found using m1×m2=-1 because we know that when lines are perpendicular, the product of their gradients must equal 1

So if we replace m1 with 1/2

1/2×m2=-1

m2=-2

We now have all the relevant information to make a substitution:

y-60=-2 (x-50)

expand brackets

y-60=-2x+100

rearrange to get in the form y=mx+b

y=-2x+160

Printed circuit cards are placed in a functional test after being populated with semiconductor chips. A lot contains 140 cards,
Ray Of Light [21]

Answer:

The probability that at least 1 defective card is in the sample is 0.9644

Step-by-step explanation:

Here

N = 140

and n = 20

We will use the below given formula

P(at least 1 defective) = 1 - P( 0 defectives)

P( 0 defectives) =

= \frac{^{20}C_0 * ^{120}C_{20}}{ ^{140}C_{20}}\\= 0.0356 1-0.0356 \\= 0.9644

After earning 300 points on a game show, Katie got to compete in the bonus round. By the end of the bonus round, she had a total
inessss [21]

Answer:

500

Step-by-step explanation:

First we make an equation to find the score for the bonus round. x is the score for the bonus round .

300 + x = 800

Next we subtract 300 from both sides of the equation

300 - 300 + x = 800 - 300

Which get us

0 + x = 500

x = 500

Her score in the bonus round is 500
