KengaRu [80]3 years ago
7 0

Answer:

The answer is that w = 30

Step-by-step explanation:

To find this, we start by modeling the equation.

w/5 + 2 = 8

We know it looks like this since they say quotient, which means division problem.

w/5 + 2 = 8

w/5 = 6

w = 30

maks197457 [2]

The population will reach 540 000 in 30.8 yr.

The formula for population growth is

<em>P</em>_<em>t</em> = <em>P</em>_0 × e^(<em>rt</em>)

540 000 = 270 000 × e^(0.0225t)

e^(0.0225t) = 2

0.0225t = ln2

t = (ln2)/0.0225 = 30.8

Which shows the correct first step to solving the system of equations in the most efficient manner? 3 x 2 y = 17. X 4 y = 19. X
Shkiper50 [21]

The correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

The given system of equations is;

\rm 3 x + 2 y = 17\\\\x + 4 y = 19

<h2>What is the first step to solving an equation?</h2>

The first step would be to rearrange the variables in the second equation so we have a defined expression for x.

We would want to do this so we could then plug in the defined expression for x into the other equation and solve for the other variable.

x + 4y = 19

Rearrange this by getting the 4y to the other side.

We can get 4y on the other side by subtracting 4y from both sides

x + 4y - 4y = 19 - 4y

x = -4y + 19

Hence, the correct first step to solving the system of equations in the most efficient manner is x = -4y +19.

If a certain machine makes electrical resistors having a mean resistance of 40 ohms and a standard deviation of 2 ohms, what is
Anna71 [15]

Answer:0.0668

Step-by-step explanation:

Given

mean of sample \mu =40

Standard deviation \sigma =2

For n=36 sample

Random variable Z=\frac{X-\mu }{\frac{\sigma }{\sqrt{n}}}

For combined resistance of 1458 ohm mean resistance of \mu =\frac{1458}{36}=40.5

P(40.5

=P(\frac{40.5-40}{\frac{1}{3}}

=P(1.5

=1-P(Z\leq 1.5)

=1-0.9332

=0.0668
