Use the Pythagoras' Theorem:

A^2 + B^2 = C^2

20^2 + 35^2 = C^2

400+ 1225=1625=C^2

square root of 1625= C = 40.31 km

If one point on a line is (-2,8) and the line’s slope is -3/2 find the y intercept
stellarik [79]

Answer:

The y intercept is 5

Step-by-step explanation:

The slope intercept form of an equation is

y = mx+b  where m is the slope and b is the y intercept

y = -3/2x+b

Substitute the point into the equation and solve for b

8 = -3/2(-2)+b

8 = 3+b

8-3 =b

5=b

The y intercept is 5

A boxcar contains six complex electronic systems. Two of the six are to be randomly selected for thorough testing and then class
zlopas [31]

Answer:

Step-by-step explanation:

Number of electronic systems = 6

(a) Number of defected systems = 2

Probability of getting at least one system is defective

1 defective and 1 non defective + 2 defective

= (2 C 1 ) x (4 C 1) + (2 C 2) / (6 C 2)

= 3 / 5

(b) four defective

Probability of getting at least one system is defective

2 defective and 2 non defective + 3 defective and 1 non defective + 4 defective  

= (4 C 2 ) x (2 C 2) + (4 C 3 )(2 C 1) + (4 C 4) / (6 C 4)

= 1
