P= 3000 (1.21)^t, t= time in months
1 year = 12 months, and therefore, 1 month = 1/12 years
The equation showing yearly population growth changes to;
P=3000 (1.21)^t/12
The correct answer is equation [1].
Answer:
The probability that R2 is bigger than R1 is P=0.9633.
Step-by-step explanation:
We need to compute the probability that R2 is bigger than R1:

To do this, we define a new variable Das the difference between the two resistances:

Then,

As R1 and R2 are normal random variables, the properties of D are:

Then, we can calculate the z-value for D=0


Answer:
The solution to the given inequality

Step-by-step explanation:
Given inequality

⇒ -1≤ 7× 3h
⇒ -1 ≤ 21 h
⇒ 21 h ≥ -1
⇒ 
Let the ratio of the number of blue to yellow cards be 4:3
since blue has 4 parts and yellow has 3, the total would be 7 equal parts which sum up to 84
--> each part is equal to 12
blue has 4 parts so there are 4*12=48 blue cards in total
