Answer:
c = 10
Step-by-step explanation:
3 is to 6 as 5 is to c:
3 5
----- = -----
6 c
Then 3c = 30, and c = 10
Assuming the rule is multiply by 6, I would say 216.
Answer:
a) 1/22
b) 3/44
c) 3/11.
Step-by-step explanation:
a).
Prob(picking a blue first) = 5/12.
Prob(picking a yellow next) = 4/11 ( as it is without replacement)
Prob(purple next) = 3/10
Probability of picking these in this order = 5/12 * 4/11 * 3/10
= 1/22 (answer).
Note the probabilities are multiplied because the 3 events are independent.
b)
Prob(all the same colour) = Prob(All are blue) + Prob(all are yellow) + Prob ( All are purple)
Prob(All are blue) = 5/12 * 4/11 * 3/10 = 1/22
Prob(all are yellow) = 4/12 * 3/11 * 2/10 = 1/55
Prob(all purple) = 3/12 * 2/11 * 1 /10 = 1/220
So probability there are all the same colour = the sum of the above
= 3/44 (answer).
c) I take this to mean that all 3 are a different colour.
This will be the number of combinations of blue, yellow and purple possible which is 3! = 6.
So the answer is 6 * 1/22 = 3/11.
<span>1/7 is the unit fraction or the simplest form of the given 12/84
Look into:
Equivalent fractions are fractions having the same value even if they look different. Look different means they may not have the same denominator or numerator but, when you multiply the top (numerator) and the bottom (denominator) by the same integer, the fraction keeps its value. </span>
<span> Equivalent fractions can be simplified and written as the same fraction for example, 18/27 = 6/9 = 2/3. </span>
<span>Example: </span>
<span>Two equivalent fractions of 8/24. </span>
<span>8/ 24 can also be 1/3. Why? How did it happen? </span><span>
Simply, get the GCF, the Greatest Common Factor or the GCD, Greatest common Divisor of both numerator and denominator.</span>
<span>8 = 1, 2, 4, 8 </span>
<span>24 = 1, 2, 3, 4, 6, 8, 12, 24 </span>
8 is the greatest common factor of 8 and 24 so,
<span><u>_8 </u>÷ <u> 8_ </u> = <u>_1_</u></span><span> </span><span>
24 8 3</span><span> </span>
8/24 is also equivalent to 2/6. Thus;
<span>8/24=2/6=1/3 <span>
