first isolate y so it is in slope intercept formula:

8x-3y=9

Subtract 8x from both sides

8x - 8x - 3y= 9 - 8x

-3y = 9 - 8x

Now divide both sides by -3 to isolate y

-3/-3y = 9/(-3) - 8x/(-3)

y = -3 + 8/3x

y = 8/3x - 3

Slope: 8/3

Hope it helps :)

y= mx+b

m is also slope

b= y-intercept

8x-3y=9

move 8x to the other side

sign changes from +8x to -8x

8x-8x-3y= -8x+9

-3y= -8x+9

divide both sides by -3

to get +y

to get y by itself

-3y/-3= -8x/-3+9/-3

y= 8/3x-3

Answer:

slope= 8/3

We use the simple rules of statistics to accept the null hypothesis
68% of the data falls within 1 sd of the mean95% of the data falls within 2 sd of the mean 99% of the data falls within 3 sd of the mean
20 falls between the range of -56 to 56 (from the given 95% c.i.), hence we accept the null hypothesis; else, if the mean falls outside the range, we reject the null hypothesis.

Answer:

0.3125 = 31.25% probability that it is not ideal.

Step-by-step explanation:

For each children, there are only two possible outcomes. Either it is a girl, or they are not. The probability of a child being a girl is independent of any other child. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
