Svetach [21]

Answer:

$0.004 per gallon

Step-by-step explanation:

Given:

Service Fee= $22

Fixed rate per gallon= m

Water Consumed= 2256 gallons

Total bill charged= $31.02

Now by computing the equation we get

$\textrm{Total bill charged} = \textrm{Service fee} + (\textrm{fixed charge per gallon} \times \textrm{water consumed})$

Substituting data we get

$22+m2256=31.02$

$m2256= 31.02-22$

$m2256=9.02$

$\therefore m =\frac{9.02}{2256} =0.00399$

Rounding off above value we get

$m=0.004$ per gallon

irina [24]

Answer: Our required probability is 0.99338.

Step-by-step explanation:

Since we have given that

n = 100

p = 0.200

So, $np=100\times 0.2=20>5$

So, we can apply normal approximation.

Mean = 20

Standard deviation = $\sqrt{npq}=\sqrt{100\times 0.2\times 0.8}=\sqrt{16}=4=\sigma$

Since $z=\dfrac{\bar{X}-\mu}{\sigma}$

So, Probability that fewer than 30 but a packet after testing a free sample is given by

$P(X$

Hence, our required probability is 0.99338.

Answer:

Step-by-step explanation:

$40k = - 36$
