Write an equation of a line that is perpendicular to the line 2x-3y+15=0
loris [4]

Answer:

y =- \frac{3}{2} x+1

Step-by-step explanation:

The equation of the given straight line is 2x - 3y + 15 = 0.

Now, we can express the equation as 3y = 2x + 15

⇒ y = \frac{2}{3} x+ 5 ..........(1)

The equation is in slope-intercept form and the slope is =\frac{2}{3}

Therefore, the equation of a straight line which is perpendicular to (1) is  

y = -\frac{3}{2} x+c {Where c is any constant}

{Since, the product of slopes of two perpendicular straight lines is -1}

Now, putting c = 1, we get the equation as y =- \frac{3}{2} x+1. (Answer)

A battery company produces 12,000 batteries per day. Each day they randomly select 50 to test. If they find that 1 is dead, how
alexgriva [62]

Using the binomial distribution, it is found that they would expect to find 240 dead batteries among the entire 12,000.

For each battery, there are only two possible outcomes, either it was dead or it was not. The probability of a battery being dead is independent of any other battery, hence the binomial distribution is used to solve this question.

<h3>What is the binomial probability distribution?</h3>

It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

In this problem, we have that:

  • One in 50 batteries are dead, hence p = 1/50 = 0.02.
  • There is a total of 12,000 batteries, hence n = 12000.

Then:

E(X) = np = 12000(0.2) = 240

They would expect to find 240 dead batteries among the entire 12,000.

What is the distance between the points (4,5) and (10,13) on a coordinate plane?
Readme [11.4K]
The distacne between the points (x1,y1) and (x2,y2) is
D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
so the distance between (4,5) and (10,13) is
well, first
x1=4
y1=5
x2=10
y2=13
so

D=\sqrt{(10-4)^2+(13-5)^2}
D=\sqrt{(6)^2+(8)^2}
D=\sqrt{36+64}
D=√100
D=10
the distance is 10 units
