Eight subtracted from the square of a number

1 answer:

5 0

That is an incomplete question… what you’re saying is

8-x²=y

That’s impossible unless you know what it is squared by or what it equals.

Is the line through points P(0, –9) and Q(2, –8) perpendicular to the line through points R(1, 4) and S(3, 3)? Explain

Serjik [45]

The quickest way to tell if a line is perpendicular is to find the slope, so you'll need to get the slope for both lines

PQ = ((-8) - (-9))/(2 - 0) = 1/2

and, for reference, a perpendicular slope is the negative reciprocal of the original (so we're looking for -2)

RS = (3 - 4)/(3 - 1) = -1/2

so, no, these two lines aren't perpendicular because the slope of RS is only the negative of PQ, not the negative <em>reciprocal</em>.

A single number is chosen from the digits 1 through 30. Find the probability that the number is an even number or a number divis

ladessa [460]

Answer:

There is a 66.67% probability that the number is an even number or a number divisible by 3.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

These are the following even numbers from 1 through 30: 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30

There are 15 even numbers.

These are the following numbers divisible by 3 from 1 through 30:

3,6,9,12,15,18,21,24,27,30

We only count the odd numbers here, since we have already counted the even ones.

There are 5 odd numbers divisible by 3.

So there are 20 numbers that are even numbers or divisible by 3. So there are 20 desired outcomes.

Total outcomes:

There are 30 numbers from 1 through 30. So the number of total outcomes is 30.

Find the probability that the number is an even number or a number divisible by 3.

$P = \frac{2}{3} = 0.6667$

There is a 66.67% probability that the number is an even number or a number divisible by 3.
