Answer:

Answer:

Initial temperature = 20° C

Temperature after 18 minutes = 4° C

Step-by-step explanation:

Function representing the relation in the temperature of the soda and time has been given as,

T(x) = -8+28e^(-0.045x)

Here x = number of minutes since the can was placed in the cooler

For initial temperature of the soda,

x = 0,

T(0) = -8+28e^((28* 0))

      = -8 + 28(1)

      = 20° C

For the temperature after 18 minutes,

x = 18,

T(18) = -8+28.e^(-0.045* 18)

       = -8+28.e^((-0.81))

       = -8+12.456

       = 4.456 C

       ≈ 4° C

Answers

Answer:

I:40,ii:65,iii:75,iv:40,v:75,vi:15

Step-by-step explanation:

75+65+i=180

140+i=180

i=180-140

i=40

i=iv=40(alternative angle)

65+40+v=180(straight line angle)

105+v=180

v=180-105

v=75

v=iii=75(alternative angle)

90+75+vi=180

165+vi=180

vi=180-165

vi=15

40+75+ii=180

115+ii=180

ii=180-115

ii=65

In our decimal​ system, we distinguish odd and even numbers by looking at their ones​ (or units) digits. If the ones digit is even​ (0, 2,​ 4, 6,​ 8), the number is even. If the ones digit is odd​ (1, 3,​ 5, 7,​ 9), the number is odd. Determine whether this same criterion works for numbers expressed in base four

Answers

Answer:

Yes. In base 4 numbers if a number ends with 0 or 2 then it is an even number. If it ends with 1 or 3 then it is an odd number.

Step-by-step explanation:

The first 13 numbers in base 4 are written in brackets next to their corrsponding decimal number below

decimal number 0(0) ,1 (1) ,2(2), 3(3), 4(10), 5(11), 6(12), 7(13), 8,(20), 9(21), 10(22), 11(23), 12(30), 13(31) and so on

From above we can deduce that in base-4 any number ending with 0 or 2 is an even nmuber and any number ending with 1 or 3 is an odd number

There are​ 15,958,866 adults in a region. If a polling organization randomly selects 1235 adults without​ replacement, are the selections independent or​ dependent? If the selections are​ dependent, can they be treated as independent for the purposes of​ calculations? Are the selections independent or​ dependent?

Answers

Answer:

The selections are dependent.

Yes, they can be treated as independent (less than 5% of the population).

Step-by-step explanation:

Since the selections are made without replacement, each selection affects the outcome of the next selection and, therefore, the selections are dependent.

Although they are dependent, the selections can be treated as independent if the sample size is no more than 5% of the total population. In this case, the sample size is 1235 adults out of a population of 15,958,866 adults. The percentage represented by the sample is:

P=(12,345)/(15,958.866)*100\n P=0.077\%

Thus the selections can be treated as independent for the purposes of calculations.
