Consider the following equations: −x − y = 1 y = x + 3 If the two equations are graphed, at what point do the lines representing
ASHA 777 [7]

Equation 1: -x-y = 1y, -x = 2y

Equation 2: 1y = x+3 , y = x+3

Substitute equation 2 into equation 1

-x = 2y

-x = 2(x+3)

-x = 2x + 6

-3x = 6

x = -2

Substitute x=-2 into equation 2

y = x+3

y = -2+3

y = 1

So, (x,y) = (-2,1)

There are three executives in an office, ages 56, 57, and 58. If a 57-year-old executive enters the room, the
vova2212 [387]

Answer:

option (c) The mean age will stay the same but the variance will decrease

Step-by-step explanation:

Case I: For 3 executives of ages 56, 57 and 58

Number of executives, n = 3

Mean = \frac{\textup{56 + 57 + 58 }}{\textup{3}}

or

Mean = 57

Variance = \frac{\sum{(Data - Mean)^2}}{\textup{n-1}}

or

Variance = \frac{(56 - 57)^2+(57-57)^2+(58-57)^2}{\textup{3-1}}

or

Variance = \frac{1+0+1}{\textup{2}}

or

Variance = 1

For Case II: For 4 executives of ages 56, 57, 58 and 57

Number of executives, n = 4

Mean = \frac{\textup{56 + 57 + 58 + 57 }}{\textup{4}}

or

Mean = 57

Variance = \frac{\sum{(Data - Mean)^2}}{\textup{n-1}}

or

Variance = \frac{(56 - 57)^2+(57-57)^2+(58-57)^2+(57-57)^2}{\textup{4-1}}

or

Variance = \frac{1+0+1+0}{\textup{3}}

or

Variance = 0.67

Hence,

Mean will remain the same and the variance will decrease

Hence,

The correct answer is option (c) The mean age will stay the same but the variance will decrease

How can I solve the statement below?
QveST [7]

9514 1404 393

Answer:

  A ≈ 65.4°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...

  Cos = Adjacent/Hypotenuse

  cos(A) = b/c

  A = arccos(b/c) = arccos(2.5/6)

  A ≈ 65.4°
