Answer:

Step-by-step explanation:

a )

probability of a computer being ancient = .99

probability of a computer being cutting-edge =.01

probability of two selected  computer being old

= .99 x .99

= .98 or 98%

b )

probability of 5 selected computers being old

= .99 x .99 x .99 x .99 x .99

= .95 or 95%

c )

probability that at least one of the five selected computers is cutting-edge

= 1 - probability of 5 selected computers being old

= 1 - .95

= .05

Select all the statements about the situation that are true. Elena makes more money for making 10 calls than Diego makes for was
steposvetlana [31]

Answer:

B, C, E

Step-by-step explanation:

Elena’s aunt pays her $1 for each call she makes to let people know about her aunt’s new business. The table shows how much money Diego receives for washing windows for his neighbors.

Select all the statements about the situation that are true.

A. Elena makes more money for making 10 calls than Diego makes for washing 10 windows.

Elena:

$1 = 1 call

$10 = 10 calls

Diego:

27 windows = $30

10 windows = $x

Cross product

27*x = 30*10

27x = 300

x = 300/27

x = $11.11

Statement A not true

B. Diego makes more money for washing each window than Elena makes for making each call.

Diego:

10 windows = $11.11

Each window = $11.11/10

= $1.11

Statement B is true

C. Elena makes the same amount of money for 20 calls as Diego makes for 18 windows

Elena:

20 calls = $20

Diego:

18 windows = 18 × $1.11

= $19.98

Approximately $20 to the nearest whole dollar

Statement C is true

D. Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls.

Diego

35 × $1.11 = $38.85

Approximately $39

Elena:

40 calls = $40

Statement D is not true

E. The equation y = x, where y is the number of dollars and x is the number of calls, represents Elena’s situation.

Statement E is true

Solve the multi step literal equation: solve equation for A b^2A^2-3g=q
I am Lyosha [343]

Answer:

A = ± \sqrt{\frac{q+3g}{b^2} }

Step-by-step explanation:

Given

b²A² - 3g = q ( add 3g to both sides )

b²A² = q + 3g ( divide both sides by b² )

A² = \frac{q+3g}{b^2} ( take the square root of both sides )

A = ± \sqrt{\frac{q+3g}{b^2} }
