Answer:
ten or an eight because there is a 2/3 chance that it will land on those
Step-by-step explanation:
A I believe because Against the odds of 38/50 would be 12/50 that is not an option so split in half this would be A cause its an equivalent fraction
4859/10000 (rounded it's 48/100= 12/25)
Answer:
I think its 2/9 but im not sure worth a try doe
Answer:40
Step-by-step explanation:This is a variation question
From the statement. Let the mental age be M and the chronological age be C, then
IQ ∝M ∝1/C
⇒ IQ ∝ M/C
Introducing the proportionality constant
IQ = KM/ C
Given : M = 15, C = 30 , 1Q = 20
Substitute the given values into the equation
i.e 120 = K x 15/ 30
120 = k/2
therefore k = 240
substitute k = 240 into the equation, we have
IQ = 240M/C
To find C when IQ is 120 and M is 20, we will substitute into the generated formula
i.e 120 = 240 x 20 / c
120c = 480
C = 480/120
C = 40
Therefore , the chronological age of a person with mental age of 20 and IQ of 120 is 40
