What fraction of the days did the carnival have 70 or fewer visitors?
Submit
Answer:
its 1/4 :)
Step-by-step explanation:
After observing the number of visitors, the fraction of the days that the carnival has 70 or fewer visitors is 1/3.
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction.
It can be written in the form of p:q, which is equivalent to p / q.
Given that,
There are 2 days with 70 or fewer visitors.
To find the required fraction,
Determine how many days out of the given total had 70 or fewer visitors.
Since there are 2 days with 70 or fewer visitors,
To calculate the fraction,
Divide the number of days with 70 or fewer visitors (2) by the total number of days (6).
So, the fraction is 2/6.
Simplifying this fraction yields 1/3.
Hence, the required fraction is 1/3.

A long history of testing water samples in a certain lake has shown that the level of a certain pollutant is approximately normally
distributed with standard deviation 4.5 mg/L. What is the minimum number of samples required to estimate today's level to within 0.4
mg/L with 95% confidence? (Don't forget to round Zc to two decimal places!)
Answer:
The minimum number of samples required is 487.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Standard deviation 4.5 mg/L.
This means that [tex]\sigma = 4.5[/tex]
What is the minimum number of samples required to estimate today's level to within 0.4 mg/L with 95% confidence?
This is n for which M = 0.4. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]0.4 = 1.96\frac{4.5}{\sqrt{n}}[/tex]
[tex]0.4\sqrt{n} = 1.96*4.5[/tex]
[tex]\sqrt{n} = \frac{1.96*4.5}{0.4}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96*4.5}{0.4})^2[/tex]
[tex]n = 486.2[/tex]
Rounding up
The minimum number of samples required is 487.

Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. The total cost of Haley’s monthly cell phone bill can be expressed by the function C(m) = 0.05m + 20, where m is the number of minutes used. What are the domain and range of the function C(m)?
Answer:
The domain is [tex]D_C = [0,\infty)[/tex]
The range is: [tex]R_C = [20,\infty)[/tex]
Step-by-step explanation:
Domain and range of a function:
The domain of a function are the values that the input assumes, while the range are the values that the output assumes.
In this question:
[tex]C(m) = 0.05m + 20[/tex]
m is the input, which is the number of phone calls, which can be any number between 0 and infinite. So
The domain is [tex]D_C = [0,\infty)[/tex]
When the input is m = 0, the value of C(0) = 20. As m increases, so does C(m). This means that:
The range is: [tex]R_C = [20,\infty)[/tex]
Answer:
Option 1 because
domain: m is Greater than or equal to zero
range: C is greater than or equal to twenty
Step-by-step explanation:
The (C) cost of the bill is always going to start at twenty and be higher depending on how many (m) minutes were used.

So, 180-45=135
Therefore, the answer is 135* or b
hope this helps
Answer:
135 degrees
Step-by-step explanation:
Since the angle is measured from the center, the arc is the same as the angle measurement.
ACB = 180
AC + CB = 180
AC + 45 = 180
AC = 180-45 = 135

Lincoln is seeking a loan with a simple interest rate of 8% per year. If he wants to borrow $5000, then how much will he be charged in interest for 24 months? $8,000 $9,600 $1,250 $800
Answer:
Lincoln will be charged $9,600.
Step-by-step explanation:
To find the answer we will first turn 8% into a decimal. 8 ÷ 100 = 0.08. Now multiply 0.08 by $5,000 and we get $400. then multiply $400 by 24 and we get $9,600. Therefore, $9,600 is our answer.

Answer:
x = 42
Step-by-step explanation:
Let the length of the indicated side be represented as "x".
The Theorem of proportionality can be extended and applied to find the indicated side.
Thus, based on the theorem, it is assumed that the parallel lines divides the transversals proportionally.
This implies that:
x/(77 - x) = 30/25
x/(77 - x) = 6/5
Cross multiply
x(5) = 6(77 - x)
5x = 462 - 6x
Add 6x to both sides
5x + 6x = 462
11x = 462
x = 462/11
x = 42

The number of truckloads of dirt required for coverage will be ...
(615.8 ft²)/(75 ft²/truckload) ≈ 8.21 truckloads
Since the dirt comes only in whole truckloads, Hilary needs 9 truckloads.

BRIANLIST Caitlin has $24 to spend. She spent $8.50, including tax, to buy a book. She needs to save $6.25, but she wants to buy some candy. If each piece of candy costs $0.25 including tax, what inequality would show the maximum number of pieces Caitlin can buy? Let x represent the cost of one piece of candy.
Solve your inequality by showing your work and steps.
Answer: 37 pieces of candy
Step-by-step explanation:
24-8.50 is 15.50 she wants to save 6.25, so, 15.50-6.25 is 9.25. 9.25 divided by the cost of each candy (0.25) is 37

2. (MCC 6.5) Find the value of x. 77° (6x17)°
Answer:
x = 17
Step-by-step explanation:
77° + (6x + 1)° = 180° (angels on a straight line)
Solve for x
77 + 6x + 1 = 180
Add like terms
6x + 78 = 180
6x + 78 - 78 = 180 - 78
6x = 102
6x/6 = 102/6
x = 17
