Why is the answer for 23 C?<br><br>and why isn't it D?​
Vaselesa [24]

Answer:

C

Explanation:

The answer is not D because the money is doubling every n years. We do not need to know what n equals to know that since n is doubling, this is an exponential function. The graph in D is going at a constant rate, and exponential functions do not increase/decrease at a constant rate. This also eliminates A. B is not correct because the money will keep increasing and not decrease eventually like the graph in B shows.

Perform hypothesis testing using the critical value approach brainly.
lord [1]

There are a lot of ways to test for an hypothesis.  There are known five steps of a test of hypothesis through the use of the critical value approach. They are;

  1. One has to Specify the Null Hypothesis.  
  2. You  have to also specify the Alternative Hypothesis.
  3. Then you set the Significance Level.
  4. Calculate the Test Statistic and Corresponding P-Value.  
  5. Lastly, Draw a Conclusion.

<h3> The critical value approach? </h3>
  • This is known as a method that involves the determining of the "likelihood" or "unlikelihood" by knowing if or not the observed test statistic is said to be of a more extreme measure than would be expected if the null hypothesis were true.

It often uses the sample data and then there is an assumption if the null hypothesis is true before one can calculate the value of the test statistic.

Suppose that 3. 33 g of acetone at 25. 0 °c condenses on the surface of a 44. 0-g block of aluminum that is initially at 25 °c.
Vlada [557]

The final temperature on the block is 25 degrees.

Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.

Data given;

  • M1 = 3.33g
  • T1 = 25 degrees
  • M2 = 44g
  • T2 = 25 degree
  • C1 = 124.5 J mol K
  • C2 = 0.89 J/g K
<h3>Heat Transfer</h3>

Applying the principles of heat transfer,

Heat loss = Heat gain

m1c1(T1 - T3) = m2c2(T3 - T2)\\3.33*124.5*(25.0 - T3) = 44*0.89*(T3 - 25)\\10364.625 - 414.585T3 = 39.16T3 - 979\\10364.625+979 = 414.585T3 +39.16T3\\11343.25 = 453.745T3\\T3 = \frac{11343.25}{453.745} \\T3 = 24.999\\T3 = 25

From the calculation above, the final temperature on the block is 25 degrees.

Distinguish between catabolism and anabolism giving an example of each
Alex
Catabolism is what happens when you digest food and the molecules break down in the body for use as energy. Large, complex molecules in the body are broken down into smaller, simple ones.
