Answer: Choice C)

(1/30)*(1/29)

Explanation:

Jack has a 1/30 chance of being picked since he is 1 person out of 30 total. After his name is picked, and not put back, there are 30-1 = 29 names left. The chances Jill is picked is 1/29. The two fractions are multiplied to get the overall probability both are picked.

The numeric value of the expression d² + 3a + 6 + a when a = 2 and d = 5 is of 39.

<h3>How to find the numeric value of an expression?</h3>


The numeric value of a function is found replacing each instance of a variable by the value of the input for which we want to find the numeric value.

For this problem, the expression is given by:

d² + 3a + 6 + a

We want to find the numeric value when a = 2 and d = 5, hence:

5² + 3(2) + 6 + 2 = 25 + 6 + 6 + 2 = 39.

If g(x) = -3x + 12, what is the solution set<br> if the domain of gis (-2, 0,2}?
disa [49]

Given:

The function is

g(x)=-3x+12

Consider the given domain of g is {-2,0,2}.

To find:

The solution set  if the domain of g for the given domain.

Solution:

Domain is the set of input values and range is the set of output value.

We have,

g(x)=-3x+12

Domain of g is {-2,0,2}.

For x=-2,

g(-2)=-3(-2)+12

g(-2)=6+12

g(-2)=18

For x=0,

g(0)=-3(0)+12

g(0)=0+12

g(0)=12

For x=2,

g(2)=-3(2)+12

g(2)=-6+12

g(2)=6

Now, the solution set  of the given domain of g is

\{f(-2),f(0),f(2)\}=\{18,12,6\}

Therefore, the solution set is {18,12,6}.

Sav [38]
Number of bacteria = 64•(1.5^(t/4))
So after t=100 hours,
64•(1.5^25) = 1,616,075 or 1.616x10^6
