In a test of a printed circuit board using a random test pattern, an array of 16 bits is equally likely to be 0 or 1. Assume the
Doss [256]

Answer:

A) b) and c) answer has been explained below.

Step-by-step explanation:

For the question would use 1's and 0's and taking probabilities to be equal for both using random test pattern whose formula is when p = q

then Simplify to

P[k] =  nCk /2^n

A.Probability that all bits are 1s

16c16/2^16 = 1/65536

B. Probability that all bits are 0s

16c0/2^16 = 1/65536

C.the probability that exactly 8 bits are 1s and 8 bits are 0s

16c8/2^16 = 12870/65536 =>0.1963 ≈ 19.63%

What does 2.975 round to?
Nezavi [6.7K]
2.975 round up to 3.

2.975 rounded up to the nearest hundredths is 2.98
2.975 rounded up to the neared tenths will automatically be 3. because 0.97 rounded up to the neared tenths will result to 1.0.

2.975 rounded up to the nearest ones is 3.

Any number that must be rounded to the nearest place must be aware of the number next to it. If the following number is 5 and up, the number place is rounded up. If the next number is 4 and below, the number place is rounded down.

A cake recipe says to bake the cake until the center is 180°F. then let the cake cool to 100°F. The table shows temperature read
mina [271]

Answer:

8.058655822 mins

Step-by-step explanation:

We have a  table and to solve for this we might want to find the  equation for this

This is a exponential function

To solve for this we need the rate of decay and the x intercept

We know the x intercept is 180 because in 0 mins the temp is 180

To solve for decay we need to know the temp of the cake after 1 min

to get the decay value we can do

125=  180 (x)^5

.69444444444 = x^5

0.929667185 = x

so the equation would be

180 (0.929667185)^x

if we tell this equation to equal 100

we get

100 = 180 (0.929667185)^x

.5556 = (0.929667185)^x

log .5556 = log 0.929667185 *x

log .5556 / log .929667185)

8.058655822= x

After 8.058655822 mins the cake will be 100 degrees
