Answer:

31.8%

Step-by-step explanation:There are 7 months that have 31 days so,

The odds the first selected month has 31 days is 7/12

The next month there are only 6 months left with 31 days of only 11 months to choose from

so the odds for the second are 6/11

To calculate the odds they BOTH have 31 months you multiply the two odds:

(7/12) x (6/11) = 42/132 = .318 so 31.8%

Answer:

D. 12 units

Step-by-step explanation:

The distance between two points is found by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

sqrt( (4 -4)^2 + (-5-7)^2)

sqrt((0^2 + (-12)^2)

sqrt(0+144)

sqrt(144)

Two numbers, a and b, are stored in one byte floating point notation using the least significant (rightmost) 3 bits for the expo

ehidna [41]

$a=00110111 = 00110_2 \times 2^{111_2} = 6 \times 2^{-1} = 3$

$b=11011000 = 11011_2 \times 2^{000_2} = -(0100_2 + 1) =-(4+1)=-5$

$a+b=-2 = -1 \times 2^{001} = -2 \times 2^{0} = -4 \times 2^{-1}$ etc.

$a+b=-2 = 11111001 = 11110000 = 11100111 = ...$

Hard to select the correct answers without seeing the choices. Let's check a couple,

$11111001 = -(00000+1) \times 2^{1} = -2 \quad\checkmark$

$11110000 = -(00001 + 1) \times 2^{0} = -2 \quad\checkmark$

$11100111 = -(00011 + 1) \times 2^{-1} = -4/2= -2 \quad\checkmark$

Step-by-step explanation:

329/8=41.125 you divide by 8 because its equivalent to 8 smaller units.

Then: 41.125 x 724=approx. 30,000
