<u>Answer:</u>
Difference between the experimental and the theoretical probability is 2/5 .
<u>Step-by-step explanation:</u>
Spinner is spun 10 times, and experimental probability of landing on a 3 is 1/2, i.e. out of 10 times spinner lands 5 times into 3.
Now, theoretical probability of landing on a 3 is 1/10.
∴ Difference between the experimental and the theoretical probability :
<em> ⇒ (1/2) - (1/10) </em>
<em> ⇒ </em><em>2/5</em>
Answer:
x = -5
, y = 0
Step-by-step explanation:
Solve the following system:
{4 x + 7 y = -20 | (equation 1)
2 x - 5 y = -10 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 7 y = -20 | (equation 1)
0 x - (17 y)/2 = 0 | (equation 2)
Multiply equation 2 by 2/17:
{4 x + 7 y = -20 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{4 x + 7 y = -20 | (equation 1)
0 x+y = 0 | (equation 2)
Subtract 7 × (equation 2) from equation 1:
{4 x+0 y = -20 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -5 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = -5
, y = 0
Answer: (3,45) and (15,9)
Step-by-step explanation:
LCM x HCF = 45*3 = 135
so, the pairs which has HCF as 3 and LCM as 45 are (3,45) and (15,9)
