3. Represent each addend with number disks in the place value chart. Show the composition of larger units
elena-14-01-66 [18.8K]

Answer:

  4(1000) +11(100) + 24(10,000) +11(1000) = 256,100

Step-by-step explanation:

Maybe you want to add 4000 +1100 to 24(10,000) +11,000.

1 thousand = 10 hundreds, so 4000 = 40 hundreds

  4000 +1100 = (40 +11) hundreds = 51 hundreds

__

1 ten-thousand = 10 thousands, so 24(10,000) = 240 thousands

  24(10,000) +11,000 = (240 +11) thousands = 251 thousands

__

So, we want to add 251,000 and 51 hundreds. The latter can be considered to be 5000 +100, so we have ...

  251,000 +5100 = 251,000 +5,100 = (251 +5) thousands + 1 hundred

  = 256,100

Let X denote the life of a semiconductor laser (in hours) with the following probabilities: P(X ≤ 5000) = 0.05 and P(X > 7000
Anna [14]

Answer:

a) P [ x ≤ 7000] is 0.55

b) P [ x > 5000 ] = 0.95

c)  P [ 5000 < x ≤ 7000 ] = 0,5

Step-by-step explanation:

a)  P [ x > 7000 ]  =  0.45   straightforward    P [ x ≤ 7000] is 0.55

The whole spectrum of probabilities is 1 which in this particular case is divided in two parts having 7000 as a limit, then we subtact 1 - 0.45

b) P [ x ≤ 5000]  = 0.05   again we get P [ x > 5000] taking 1-0.05 to get

P [ x > 5000 ] = 0.95

c) P [ 5000 < x ≤ 7000 ]

Under Normal curve distribution the probability of  x ≤ 7000 includes values   smallers  ( to the left of 5000) so we subtract from 0.55 - 0.05 = 0.50

c) P [ 5000 < x ≤ 7000 ] = 0,5
