Slope-intercept you have right:
y=3/4x-7

Point slope form is:
y − y1 = m(x − x1)

so

y +7 = 3/4(x -0)

or

y + 7 = 3/4x

Which angle number represents an angle adjacent to NSM?

creativ13 [48]

Answer: Answer:

1) LSM.

2)complementary angles

3)*linear pair

Step-by-step explanation:

1) Vertical angles are formed on opposite side at the intersection of two lines .In the given figure the angle vertical to OSN is LSM and hence they are vertical pair.

2) The pair of angles LSM and SMN are neither adjacent angles nor linear pair or vertical angles .Hence we can call them complementary angles.Complementary angles are one which add to 90 degrees.

3) The angle pair are NSM and MSL lie on a straight line and hence are called linear pair.

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 $1 - \frac{1}{2} = \frac{1}{2}$ .
