A six-sided number cube is rolled 900 times.
hram777 [196]

It is expected that a number greater than 4 will be rolled 300 times

The sample space of a die is:

S = {1,2,3,4,5,6}

The probability of obtaining a number greater than 4 is:

p = 2/6

p = 1/3

In 900 rolls, the expected number of number greater than 4 is:

E(x) = p *n

This gives

E(x) = 1/3 *900

E(x) =300

Hence, it is expected that a number greater than 4 will be rolled 300 times

A bag contains 26 tiles with letters A through Z. Find the probability of drawing three vowels with replacement. Find the probab
larisa86 [58]

Answer:

0.0071 & 0.004

Step-by-step explanation:

Total number of vowels 'V'=5

total number of alphabets= 26

therefore, P(V)=5/26

P(3 V's with replacement)= (5/26)³

                                             =0.0071

P(3 V's without replacement)=(5/26)(4/25)(3/23)

                                              =0.004

The first event is independent

The second event is dependent

At the moment a hot cake is put in a cooler, the difference between the cake's and the cooler's temperatures is 50\degree50°50,
Len [333]

Answer:

D(t)=50\cdot (0.8)^{t}

Step-by-step explanation:

The equation for exponential decay function is given as:

D(t)=a(1-r)^{t}

where:

D(t)= difference in temperature t=time

r=rate of change

a =initial value of the temperature

From the given problem:

Initial Temperature,a=50°C

Rate of Decay,r=\frac{1}{5}

Therefore the function for the difference in temperature is given as:

D(t)=50(1-\frac{1}{5})^{t}

D(t)=50\cdot (\frac{4}{5})^{t}

We can convert \frac{4}{5} to decimal and write the function as:

D(t)=50\cdot (0.8)^{t}
