The density of an object is obtained by taking the ratio of the mass of the object and its volume ; 
There is no picture attached and no picture corresponding to the question could be found.
- However, the required formular for calculating the density of an object is :
- The mass of the object is measured in gram(g) or kilogram(kg)
- The volume of the object measured in Litre or any equivalent unit.
Therefore, the density of the object is the ratio of its mass and volume.

Answer:
1245
Step-by-step explanation:
-Given the standard deviation is $9000 and the margin of error is $500.
-the minimum sample size at a 95% confidence level can be calculated using the formula:

Hence, the minimum sample size is 1245
*Since there's no data fromw which we are drawing our variables, we can manually input our parameters in excel and calculate as attached.
The expression for the angle m∠RST from the given bisctor is; 6x - 18
<h3>How to find the expression for a given angle?</h3>
From the given image in the attachment we are given that;
SQ bisects ∠TSR
m ∠RSQ = 3x - 9
Now, since SQ is a bisector of ∠TSR, we can say that
m∠RST = 2 * m∠RSQ
Thus angle RST is expressed as;
m∠RST = 2(3x - 9)
m∠RST = 6x - 18

Answer:
There is enough evidence at the 0.05 significance level that the percentage is less than 25%.
Step-by-step explanation:
<em>The question has no options. However, there are enough details to arrive at a conclusion.</em>
<em></em>
Required
What can we conclude about the claim of the publisher.
From the question, we understand that the null hypothesis is rejected.
In statistics, a hypothesis is rejected, if the level of significance is less than the required or determined value.
In this case, the determined value 25% and the level of significance is 0.05
<em>So, the conclusion on the claim is that there is enough evidence at the 0.05 significance level that the percentage is less than 25%.</em>
