Yes, I would say the answer is Small Sample.

In order to make an accurate study, you would want to have more than 3 samples. I would say at least 500-1000 depending on what the subject is about and where it takes place.

Let me know if this helps :) Have a nice day!

Graph the equation to solve the system. y=2x+7 1/2y=x+7/2

vlabodo [156]

Given equation is y=2x+7 and $\frac{1}{2}y=x+\frac{7}{2}$

Let's simplify the 2nd equation $\frac{1}{2}y=x+\frac{7}{2}$ before we can start graph so that calculation will be easy

$\frac{1}{2}y=x+\frac{7}{2}$

multiply both sides by 2 to cancel out fractions

$2*\frac{1}{2}y=2*x+2*\frac{7}{2}$

y=2x+7

which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.

y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.

Work out the balance for £240 invested for 20 years at 7% per annum

Luda [366]

Step-by-step explanation:

It depends in the type on interest

Simple Interest

PxRxT

£240 x 0.07x 3 = £50.4

£240 + £50.4 = £290.4

Compound Interest

Px(1+R)^T

£290.4 x (1 + 0.07)³ = £355.7524872= €355.76

Consider this expression.

Harlamova29_29 [7]

Answer:

= -30x -36

Step-by-step explanation:

-3x . 2-24x - 36= -30x - 36

-3x . 2 -24x - 36

= -6x - 24x - 36

= -30x - 36
