$20*39=  $780+$100=  $880
Subtract $314.23, and  $123 by $880
$880-$314.23-$123= $442.27
Divide $442.27 by 3.
$442.27/3 = $147.59

A pair of fair dice is cast. what is the probabiliy that the sum of the numbers falling uppermost is 9, given that at least one
WITCHER [35]
If a pair of fair dice is cast, the probability that the <span>sum of the numbers falling uppermost is 9, given that at least one of the numbers falling uppermost is a 3 is given by:

\frac{P(sum\, of\, 9\, \cup\,3)}{P(3)}

The number of outcomes of sum of 9 where at last one is 3 is (3, 6) and (6, 3) = 2.

</span>The number of outcomes of last one of the numbers falling uppermost is a 3 is (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (1, 3), (2, 3), (4, 3), (5, 3) and (6, 3) = 11.

Therefore, <span>the probabiliy that the sum of the numbers falling uppermost is 9, given that at least one of the numbers falling uppermost is a 3 is 2 / 11.</span>

Lian invested an amount of money at an interest rate of 5.2% per year.
Zigmanuir [339]

Answer:

$6500

Step-by-step explanation:

Let the amount of money invested by Lian be $x

Interest rate = 5.2% per year

interest earned in first year will be  5.2% of  amount of money invested by Lian .

(note: since in first year there will be no interest accrued on interest so interest for first year is simple interest )

interest earned in one year if money invested by Lian is $x

= 5.2% of $x  (1)

But , it is given in one year  she received interest of 338 dollars

so, 338 dollars must be equal to 5.2% of $x

equating $338 with  5.2% of $x  , we have

5.2% of x  = 338

=> (5.2/100) * x = 338

=>5.2 x = 338*100

=> x = 33800/5.2 = 6500.

Thus,  amount of money Lian invested is $6500.

Which expression is equivalent to mc003-1.jpg?
Nookie1986 [14]

Answer:

Option A is correct

The expression which is equivalent to (f\cdot g)(5) is f(5) \cdot g(5)

Step-by-step explanation:

Using the formula:

(f \cdot g)(x) = f(x) \cdot g(x)                  .....[1]

Given the expression:

(f\cdot g)(5)

Substitute the value of x = 5 in [1]

we get;

(f \cdot g)(5) = f(5) \cdot g(5)

Therefore, the expression which is equivalent to (f\cdot g)(5) is f(5) \cdot g(5)
