Answers
Answer: 6.04 inches
Step-by-step explanation:
The actual height of the monument = 604 feet
The scale used by Corbins is 1 inch = 100 feet
The height of the Corbins model in inches= [tex]\frac{604}{100}[/tex] = 6.04 inches
the height of the Corbins model = 6.04 inches

The logarithm of a quotient can be written as a difference of logarithms:
[tex]\log_3\left(\dfrac uv\right) = \log_3(u) - \log_3(v)[/tex]
You can also think of this as a combination of the product-to-sum and reciprocal/power properties of logarithms:
[tex]\log_3\left(\dfrac uv\right) = \log_3\left(u \times \dfrac1v\right) = \log_3(u) + \log_3\left(\dfrac1v\right) = \log_3(u) - \log_3(v)[/tex]
To summarize,
[tex]\log_b(mn) = \log_b(m)+\log_b(n)[/tex]
[tex]\log_b\left(\dfrac mn\right) = \log_b(m) - \log_b(n)[/tex]

Two people ran in a city election. The winner received 1 more than 3 times as many votes as the runner-up. Let w represent the number of votes the winner received. Let x represent the number of votes the runner-up received. The number of votes the runner-up received is known. Which equation represents the number of votes the winner received?
Answers
Answer:
w = 3x + 1
Step-by-step explanation:
Answer:
w=3x+1
Step-by-step explanation:
The winner (w) received 1 more (+1) than 3 times (*3) the number of votes the runner-up received. Since the runner-up is represented by x the number of votes the winner received can be represented by the equation w=3x+1.

Todd orders pictures from a photographer. Each picture costs $7.50. A one-time shipping fee of $3.25 is added to the cost of the order. The total cost of Todd's order before tax is $85.75. How many pictures did Todd order? Solve this problem using two different methods or strategies. Label your strategies.
Answers
Equation in slope intercept form
y=mx+by=7.5x+3.25So
Total paintings is x
85.75=7.5x+3.257.5x=82.5x=11 paintingsAnswer:
11 pictures
Step-by-step explanation:
Method 1Create an algebraic equation from the given information, defining the unknown quantity as a variable, then solve for the variable.
Given:
Cost of one picture = $7.50Shipping fee (one time) = $3.25Total cost of order = $85.75Let x = number of pictures ordered
⇒ Cost of one picture × number of pictures ordered + shipping fee = total
⇒ 7.5x + 3.25 = 85.75
⇒ 7.5x + 3.25 - 3.25 = 85.75 - 3.25
⇒ 7.5x = 82.50
⇒ 7.5x ÷ 7.5 = 82.50 ÷ 7.5
⇒ x = 11
Therefore, Todd ordered 11 pictures.
Method 2Logic and trial and error.
Given:
Cost of one picture = $7.50Shipping fee (one time) = $3.25Total cost of order = $85.75If the shipping fee is a one time cost, then if we subtract this from the total cost of the order, we know how much Todd spent on the pictures alone:
⇒ $85.75 - $3.25 = $82.50
We have been told that each picture costs $7.50.
Therefore, 10 pictures costs $75.00 (when multiplying by 10, we simply move the decimal point one place to the right).
$75.00 is less than $82.50. So what happens if we add another $7.50 to $75.00?
⇒ $75.00 + $7.50 = $82.50
Therefore, Todd ordered 10 + 1 = 11 pictures.
Solve for the variable

The path of the student from the home to school consists of:
0.2 miles of cherry st.0.4 miles of park st.0.1 miles of pine st.Total distance of the path of student from the home to school is,

The hypergeometric distribution should not be used, hence the correct option is given by:
no, because it is not looking for the first occurrence of success.
When the hypergeometric distribution should be used?These two conditions should be respected:
We should be looking for the probability of x successes on n trials, not the number of trials until n successes.The trials should not be independent, that is, the probabilities on each trial should be different.None of these conditions are true in this case, hence the correct option is given by:
