Answer: d) 6,534,385

Therefore, the number of ways of selecting 9 hearts is 6,534,385

Step-by-step explanation:

Given;

Number of cards to be chosen = 12

Number of hearts to be chosen = 9

Number of non-hearts to be selected = 3

Total number of cards = 52

Number of hearts total = 13

Number of non-hearts total= 39

The number of ways of selecting hearts can be given by the illustration below.

Number of ways of selecting hearts × number of ways of selecting non-hearts

N = 13C9 × 39C3 (it's combination since order is not important)

N = 13!/(9! ×4!) × 39!/(36! × 3!)

N = 6,534,385

Therefore, the number of ways of selecting 9 hearts is 6,534,385

On a​ test, if 110 questions are answered and 38% of them are​ correct, what is the number of correct​ answers?
mylen [45]
If 100% of the answers are correct ; 1*110 = 110 answers are correct.
if 50% of the answers are correct ; 0.5*110 = 55 answers are correct.
if 38% of the answers are correct ; 0.38*110 = 41.8 answers are correct.

Because the number of answers needs to be a whole number; the number of correct answers is 41.

The ribbon was 3 1/4 inches wide and had an area of 19 1/2 square inches. What is the length of the ribbon? Please Help Will Giv
miv72 [106K]
Hello!

The formula for finding area is l × w

If the area is 19 ½ inches and it was 3 ¼ inches wide, then the length will be 19 ½ ÷ 3 ¼ (Area ÷ Width)

19  \frac{1}{2} \div 3  \frac{1}{4}

Change both to improper fraction

19  \frac{1}{2} =   \frac{39}{2}

3  \frac{1}{4} =  \frac{13}{4}

\frac{39}{2} \div  \frac{13}{4}

Keep 39/2
Change ÷ to ×
Flip 13/4 = 4/13

\frac{39}{2} \times  \frac{4}{13} =  \frac{156}{26} = 6
