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.

Three times Francis' age plus five times Earl's age is 230. Earl is also four times Francis age. How old is Earl?
Answer:
E = 40 years
Step-by-step explanation:
Let the age of Francis be F.
Let the age of Earl be E.
Translating the word problem into an algebraic expression, we have;
3F + 5E = 230 ......equation 1
E = 4F .......equation 2
To find the value of F;
Substituting eqn 2 into eqn 1, we have
3F + 5(4F) = 230
3F + 20F = 230
23F = 230
F = 230/23
F = 10 years
Now, to find the value of E;
From eqn 2;
E = 4F
Substituting the value of "F" we have;
E = 4*10
E = 40 years
Therefore, Earl is 40 years old.
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

Answer:
B. 135
Step-by-step explanation:
CB is 45
AB= half of circle or 180*
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

the price per gallon of gas with a $7 car wash is $3.19 and the price without the car wash is $3.39. When is it worth it to buy the car wash? When is it worth it if the car wash costs $2?
Answer:
The price per gallon of gas with a $7 car wash is $3.19
Then if you purchase x gallons of gas and also pay for the car wash, the total cost is:
C(x) = $7 + $3.19*x
In the case that you do not pay for the car wash, the cost per gallon is $3.39
Then the cost for x gallons of gas in this case is:
K(x) = $3.39*x
When is it worth it to buy the car wash?
We need to sett the equations:
C(x) = K(x)
This means that you pay exactly the same in both cases, but in one ( C(x)) you get the car wash and in the other not.
Then we need to solve:
$7 + $3.19*x = $3.39*x
$7 = ($3.39 - $3.19)*x = $0.20*x
$7/$0.20 = x = 35
Then for 35 gallons, is worth to buy the car wash.
In the case where the car wash costs $2, then the equation C(x) becomes:
C(x) = $2 + $3.19*x
Then if we solve the same equation:
C(x) =K(x)
$2 + $3.19*x = $3.39*x
$2 = ($3.39 - $3.19)*x
$2 = $0.20*x
$2/$0.20 = x
10 = x
Then for 10 galons is whort buy the car wash.

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.

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

Answer:
615.8 square feet9 truckloadsStep-by-step explanation:
The area of the circular ring is given by the formula ...
A = πr²
where r is the radius, or half the diameter.
A = π(14 ft)² = 196π ft² ≈ 615.752 ft²
The area of the training area is about 615.8 square feet.
__
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.
