Answer:

16 = 16

Step-by-step explanation:

Cross multiplying is when you multiply the numerator and denominator of two fractions.

So, it would be 4 × 4 = 8 × 2 or 16 = 16. This is essentially proving they are equal to one another.

Hope this helps.

Answer: $P=1200x+35000$

Step-by-step explanation:

Given: A town's population has been growing linearly. In 2003, the population was 35000, and the population has been growing by 1200 (constant rate of change) people each year.

The equation of a line is given by :-

$y=mx+c$ , where m is the slope ( constant rate of change) and c is the initial value of the function.

From the given statement , we have the equation for the population x years after 2003 :-

$P=1200x+35000$

What is the value of q?

skad [1K]

Answer:

Step-by-step explanation:

ΔSQR and ΔTSR are similar. Therefore the sides are in proportion:

$\dfrac{SR}{QR}=\dfrac{TR}{SR}$

We have:

SR = q

QR = 10 + 4 = 14

TR = 4

Substitute:

$\dfrac{q}{14}=\dfrac{4}{q}$ <em>cross multiply</em>

$(q)(q)=(14)(4)\\\\q^2=56\to q=\sqrt{56}\\\\q=\sqrt{4\cdot14}\\\\q=\sqrt4\cdot\sqrt{14}\\\\q=2\sqrt{14}$

Orlov [11]

Answer:

n=601

Step-by-step explanation:

Formula used:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Solution:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Where,

$\frac{\alpha }{2}=0.025$

As there is no previous estimate for p

Then, p=0.5

Here on using the table

$z(\frac{\alpha }{2}) =1.959963985$

Also,

E=0.04

p=0.5

Thus,

n=600.2279407

On approximating the value,

n=601
