Rolling an 11:
n(A): 6&5, 5&6
n(A) = 2
Rolling a 5:
n(B): 1&4, 4&1, 3&2, 2&3
n(B) = 4

n(A) + n(B) = 4 + 2 = 6

6/10 + 20/100 = 8/10

TiliK225 [7]

6/10 can be simplified but we don't need to worry about it right now. We only need to worry about simplifying 20/100:

20/100 → 10/50 → 5/25 → 1/5

Find common denominators

1/5 → 2/10

6/10

Now, add.

6/10 + 2/10 = 8/10

Therefore, the equation is true.

Best of Luck!

$1 invested for 1 Year at 7.2% compound semiannually

WITCHER [35]

Answer:

Sum = $1.073

Interest = $0.073

Step-by-step explanation:

Given that $1 is invested for one year at 7.2% interest which compounds semi-annually.

Semi-annual means there should be two equal intervals in a year i.e. 6 months interval.

Now, the semi-annual rate of interest is $\frac{7.2}{2} = 3.6$ %.

Therefore, the invested money will become $1\times [1 + \frac{3.6}{100} ]^{2}$

= $1.073

Therefore, the interest obtained will be $(1.073 - 1) = $0.073. ( Answer )
