Answer:

R (ounces) = 34 ounces - d (1.5)

Step-by-step explanation:

Given that:

rate of evaporation = 1.5 ounce/ day

Container holds = 34 ounces

Number of days = d

Let the remaining water be represented by R (ounces)

Expression would become:

R =  Container holding capacity - number of days (rate of evaporation)

R (ounces) = 34 ounces - d (1.5)

i hope it will help you!

Suppose an airline accepted 12 reservations for a commuter plane with 10seats. They know that 7 reservations went to regular com
kvv77 [185]

Answer:

<h2>See the explanation.</h2>

Step-by-step explanation:

(a)

7 persons will show up for sure, hence there is not any kind of probability here.

The other 5 persons have 50% chance to show up.

The flight will be overbooked, if either 4 will come or 5 will come.

From the total 5 persons, 4 can be chosen in ^5C_4 = 5 ways.

The probability that any four among the 5 will come is 5\times(\frac{50}{100} )^{5} = 5\times(\frac{1}{2} )^{5} = \frac{5}{32}.

The probability that all of the 5 passengers will come is \frac{1}{32}.

Hence, the required probability is \frac{5}{32} + \frac{1}{32} = \frac{6}{32} = \frac{3}{16}.

(b)

The probability that there will be exactly 10 passengers on the flight is ^5C_3\times (\frac{1}{2} )^5 = \frac{20}{2} \times\frac{1}{32} = \frac{10}{32} = \frac{5}{16}.

The probability that there will be no empty seats in the plane is \frac{3}{16} + \frac{5}{16} = \frac{1}{2}.

Hence, probability of having empty seats is 1 - \frac{1}{2} = \frac{1}{2}.

Line CD passes through points C(3, -5) And D(6, 0). What is the equation of line CD in standard form?
Fynjy0 [20]
Y = mx + b
m = (0 - -5)/(6 - 3) = 5/3
y = 5/3x + b
0 = 5/3(6) + b
b = -10
(y = 5/3x - 10)3
3y = 5x - 30
3y - 5x = -30
5x - 3y = 30
