Answer:

When ordering three or more fractions from least to greatest, compare two fractions at a time. It is helpful to write a number in a circle next to each fraction to compare them more easily.

babymother [125]
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].

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

Solve the inequality -1/3h_<7
elixir [45]

Answer:

The solution to the given inequality

 h\geq \frac{-1}{21}

Step-by-step explanation:

Given inequality

                      \frac{-1}{3h} \leq 7

             ⇒     -1≤ 7× 3h

             ⇒     -1 ≤ 21 h

             ⇒    21 h ≥ -1

            ⇒       h\geq \frac{-1}{21}

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
