Answer:

x = 68

Step-by-step explanation:

If you look at the triangle properly, it is a isosceles triangle where two legs are equal to each other.

The answer for x will be:

56 + 56 + x =180

112 + x = 180

x = 68

Estimate the annual wages for a clerk who works 50 weeks a year and earns $15 and hour

Pachacha [2.7K]

Let us assume that a person works for 8 hours a day.

Let us assume that the person works for 5 days a week.

Wage earned per hour = $15

So, wage earned in 8 hours = 15*8 = $120

Now, wage earned in 1 day = 120

So, wage earned in 5 days = 120*5 =$600

As the person works for 5 days in 1 week

So, in 50 weeks, he will work = 50*5 = 250 days

So, total number of hours he must have worked = 250*8 =2000 hours

Now, per hour wage = $15

wage in 2000 hours = 15*2000 = $30000

Hence, the estimated wage a person earns in 50 weeks = $30000

our buses carrying 140 high school students arrive to Montreal. The buses carry, respectively, 31, 43, 27, and 39 students. One

Vinvika [58]

Answer:

V(X)= 39.10

V(Y)= 40

Step-by-step explanation:

Given that

Total number of student = 140

Bus A - 31

Bus B- 43

Bus C- 27

Bus D- 39

The probability that a student was on the bus is proportional to the number of student. Eg 31/140 in bus A, 43/140 on bus B, ...

E(X) = (31*31/140) + (43*43/140) + (27*27/140) + (39*39/140)

= 35.5

$Var(X) =(31-35.5)^2 \times \dfrac{31}{140}+(43-35.5)^2 \times \dfrac{43}{140}+(39-35.5)^2 \times \dfrac{39}{140}+(27-35.5)^2 \times \dfrac{27}{140}$

V(X)= 39.10

The bus driver have 1/4 probability on being on any of the buses.

E(Y) = 140/4 = 35

$Var(Y)=\dfrac{(35-31)^2+(35-43)^2+(35-27)^2+(35-39)^2}{4}$

V(Y)= 40

The endpoints of a side of rectangle ABCD in the coordinate plane are at A(3, 5) and B(5, 1). Find the equation of the line that

andreyandreev [35.5K]

Answer:

2x + y = 16

Step-by-step explanation:

In rectangle side AB and side CD are parallel, so the slope of both the lines will be same it means that they are parallel to each other.

slope of line AB:

$\textrm{m}=\frac{\textrm{y}_{A}-\textrm{y}_{B}}{\textrm{x}_{A}-\textrm{x}_{B}}\\\textrm{m}=\frac{5-1}{3-5}=\frac{4}{-2}=-2\\\therefore \textrm{m}=-2$

slope of line CD = slope of line AB = -2

∴ equation of line CD:

$\textrm{y}-\textrm{y}_{C}=\textrm{m}(\textrm{x}-\textrm{x}_{C})\\ \textrm{y}-2=-2(\textrm{x}-7)\\2\textrm{x}+\textrm{y}=16$
