Answer:

0.095163

Step-by-step explanation:

given that a starter motor used in a space vehicle has a high rate of reliability and was reputed to start on any given occasion with probability .99999

Here we find that for any start, there are exactly two outcomes either success or failure.

Also each start is independent of the other since p = 0.99999 for succss is given constant.

Thus X no of successes is binomial with p = 0.99999 and n =10000

If Y is taken as failure then Y is binomial with p' = 0.00001 and n =10000

Required probability

= the probability of at least one failure in the next 10,000 starts

= 1-P(no failure in 10000 starts)

=1-(0.99999)^{10000} \\=0.095163

Answer:

  2

Step-by-step explanation:

The slope is the ratio of the vertical difference between two points to the horizontal difference. This ratio is often referred to as "rise over run."

From the point (-2, -1) to the point (2, 7), the rise is 7-(-1) = 8, and the run is 2-(-2) = 4. The ratio of these numbers is ...

  slope = rise/run = 8/4

  slope = 2

_____

<em>Check</em>

The graph rises 2 units for a run of 1 unit, confirming this calculation.

K+5/3=-7/4 (those are fractions) also can you show your work?
iris [78.8K]

Answer:

-3 5/12=k

Step-by-step explanation:

K+5/3= -7/4

subtract 5/3 from both sides

K= -7/4-5/3

lcm of 4 and 3 is 12

so

K= -21/12-20/12

K= -41/12

K= -3 5/12

The length of rectangular field is 7 m less than 4 times the width. The perimeter is 136 m. Find the width and length
Elena-2011 [213]
P = 2(L + W)
P = 136
L = 4W - 7

136 = 2(4W - 7 + W)
136 = 2(5W - 7)
136 = 10W - 14
136 + 14 = 10W
150 = 10W
150/10 = W
15 = W <=== width is 15 m

L = 4W - 7
L = 4(15) - 7
L = 60 - 7
L = 53 <== length is 53 m
