Line AB contains points A (−1, 3) and B (5, 3). Line AB has a slope that is zero undefined positive negative

It would be zero

See how the Y are the same so if you were to graph it you would get a flat line and it wouldn't be undefined cause that when the X has the same value.

Answer:

Slope of AB = 0

Step-by-step explanation:

There two points of a line AB, A(-1, 3) and B(5, 3). Since slope a line is represented by m = $\frac{y-y'}{x-x'}$

Now we place the values,

$m=\frac{3-3}{-1-5}=-\frac{0}{5}$

Therefore slope of line AB is zero.

We should never get confused with the sign whether it is positive or negative.

Zero is neither negative nor positive.

Answer will be slope of AB is zero.

Answer:

Type I: 1.9%, Type II: 1.6%

Step-by-step explanation:

given null hypothesis

H0=the individual has not taken steroids.

type 1 error-falsely rejecting the null hypothesis

⇒ actually the null hypothesis is true⇒the individual has not taken steroids.

but we rejected it ⇒our prediction is the individual has taken steroids.

typr II error- not rejecting null hypothesis when it has to be rejected

⇒actually null hypothesis is false ⇒the individual has taken steroids.

but we didnt reject⇒the individual has not taken steroids.

let us denote

the individual has taken steroids by 1

the individual has not taken steroids.by 0

predicted

1 0

actual 1 98.4% 1.6%

0 1.9% 98.1%

so for type 1 error

actual-0

predicted-1

therefore from above table we can see that probability of Type I error is 1.9%=0.019

so for type II error

actual-1

predicted-0

therefore from above table we can see that probability of Type I error is 1.6%=0.016

Insert 5 G.Ms between 3 and 192

never [62]

Answer:

6, 12, 24, 48 and 96.

Step-by-step explanation:

We look for a geometric sequence with first term = 3:

nth term= a1 r^(n-1)

3 r^(n-1) = 192

r^(n-1) = 192 / 3 = 64

2 ^ 6 = 64 so r = 2.

Series is 3 ,6, 12, 24, 48, 96, 192.

So 5 geometric means would be 6, 12, 24, 48 and 96.
