Answer: 5.000

Step-by-step explanation:

The formula to find the standard deviation for binomial distribution is given by :-

\sigma=\sqrt{np(1-p)}, where p is the probability of getting success in each trial and n is the number of trials.

Given : The probability of flipping a coin and noting Heads is = 0.50

The total number of trials = 100

Then , the standard deviation of Heads to be noted will be :-

\sigma=\sqrt{100(0.50)(0.50)}=5.000

Hence, the standard deviation of Heads to be noted = 5.000

Write (-3, -5) (-1, -19) in point slope form
stiv31 [10]

Answer:

(y + 5) = -7(x + 3)

Step-by-step explanation:

Point Slope Form:  (y - y1) = m(x - x1)

<u>Step 1:  Find Slope</u>

m = \frac{y2 - y1}{x2 - x1}

m = \frac{-19 - (-5)}{-1 - (-3)}

m = \frac{-19 + 5}{-1 + 3}

m = \frac{-14}{2}

m = -7

<u>Step 2:  Put into point slope form</u>

Point Slope Form:  (y - y1) = m(x - x1)

(y - (-5)) = -7(x - (-3))

(y + 5) = -7(x + 3)
