Two resistors, with resistances R1 and R2, are connected in series. R1 is normally distributed with mean 100 ohms and standard d

puteri [66]

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:

$P(R_2>R_1)$

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

$D=R_2-R_1$

Then,

$P(R_2>R_1)=P(R_2-R_1>0)=P(D>0)$

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

$\mu_D=\mu_{R2}-\mu_{R1}=120-100=20\\\\\sigma_D=\sqrt{\sigma_{R2}^2+\sigma_{R1}^2}=\sqrt{10^2+5^2}=\sqrt{100+25}=\sqrt{125}=11.18$

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

$z=\frac{x-\mu}{\sigma} =\frac{0-20}{11.18}=\frac{-20}{11.18}= -1.79$

$P(D>0)=P(z>-1.79)=0.9633$

Help please!!! i dont get it

The amount of money in the account if compounded quarterly at 6% after 9 years is $22,217

<h3>Compound interest</h3>

Principal, P = $13,000
Time, t = 9 years
Interest rate, r = 6% = 0.06
Number of periods, n = 4

A = P(1 + r/n)^nt

= 13,000(1 + 0.06/4)^4×9

= 13,000(1 + 0.015)^36

= 13,000(1.015)^36

= 13000(1.709)

= $22,217
