What is an equation in point slope form of the line that passes through the point (6,-2) and had a slope of 3

ch4aika [34]

Answer:

y - 6 = 3(x + 2)

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Given: m(slope) = 3, (6, -2)

(x1, y1) = (6, -2)

Input the given values of the slope and the point into the equation for point-slope form:

y - (-2) = 3(x - 6)

y + 2 = 3(x - 6)

The equation written in point-slope form is: y + 2 = 3(x - 6)

The probability that a student at certain high school likes art is 36%. The probability that a student who likes art also likes

KIM [24]

Answer: Probability that a student chosen at random likes science given that he or she likes art is 58%

Step-by-step explanation:

Since we have given that

Probability that a student who likes art and science = 21%

Probability that a student who likes art = 36%

According to question,

we need to find the probability that a student chosen at random likes science given that he or she likes art.

So, we will use "Conditional Probability":

P(A) = 0.36

P(S ∩ A) = 0.21

$P(S\mid A)=\frac{P(S\cap A)}{P(A)}\\\\P(S\mid A)=\frac{0.21}{0.36}\\\\P(S\mid A)=0.58\\\\P(S\mid A)=58\%$

Hence, Probability that a student chosen at random likes science given that he or she likes art is 58%.

What is the probability that no 1s will be in the output for an input sequence of 10 digits??

emmasim [6.3K]

The total numbers with 10 digits are 9*10*10*10*10*10*10*10*10*10 = 9*(10^9)

If you are restricted to use no 1s, the numbers are 8*(9^9)

Then, the probability is : numbers with no 1s / total numbers

= 8*(9^9) / [9*(10^9)]= 0.344
