The answer is C. Stratified random sampling is a method of sampling that involves the division of a population into smaller sub-groups known as strata. In stratified random sampling or stratification, the strata are formed based on members' shared attributes or characteristics such as income or educational attainment. Since the students are divided into classes, this is a stratified random sample.

What is an inequality</h3>
Inequality is an expression that shows the non equal comparison of two or more variables and numbers.
Let x represent the number of bed and y represent the number of pillow, hence:
4x + 2y ≤ 40 (1)
Also:
2x + 4y ≤ 32 (2)
From the graph, the solution is at:
(8, 4)
Profit = 80x + 55y = 80(8) + 55(4) = $860
The maximum daily profit for the company is $860

The answer is $1000
As Change in real GDP= Change in gov. spending/(1-MPC)
So
100/(1-0.90)=1000

GDP affords an economic snapshot of a rustic, used to estimate the scale of a financial system and growth charge. GDP can be calculated in 3 methods, the use of fees, production, or earning.

The price elasticity of the bond, based on the years to maturity and the required rate of return is -0.494
<h3>How to find the price elasticity of he bond?</h3><h3 />
First, find the new price of the bond:
= 1, 000 / ( 1 + 15%)⁵
= $497
The change in price:
= (497 - 567) / 567
= -12.3%
Then find the percentage change in the required rate of return:
= (15 - 12%) / 12
= 25%
The price elasticity of the bond is:
= -12.3% / 25%
= -0.494
