The probability of flipping a coin and noting Heads is 50%. If you flip the coin 100 times, what is the standard deviation of He

BaLLatris [955]

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

Answer:

x= -1/3

y= -3 1/3

Step-by-step explanation:

Make both of them into y=Mx+b form

y=-x-3

y=(-x-7)/2

Substitute the x-3 in the first equation for the y in the second one.

x-3=(-x-7)/2

2x-6=-x-7

3x=-1

x=-1/3

Now that we have x, we can solve for y.

y=-x-3

y=-1/3-3

y=-3 1/3

andrea drove 200 miles using 9 gallons of gas. At this rate, how many gallons of gas would she need to drive 420 miles?

Anika [276]

Given : Andre drove 200 Miles using 9 Gallons of Gas

⇒ Andre drives 1 Mile using $[\frac{9}{200}]\;Gallons\;of\;Gas$

⇒ Andre drives (420 × 1 Mile) using $[\frac{420\times9}{200}]\;Gallons\;of\;Gas$

⇒ Andre drives 420 Miles using 18.9 Gallons of Gas
