six clowns perform three acts in a circus. the clowns appear two at a time. Jack, Marty, and Orville are paired with Kelly, Leslie and Nancy in some order. Kelly and her partner appear after jack and his partner. Orivlle also comes on before Kelly, and Leslie appears before Nancy. Jack and Leslie are partners. Witch pair peforms second?
Answer:
The pair that performs second are Orville and Nancy.
Step-by-step explanation:
Since Jack and Leslie are partners and that they appear before Kelly, it is safe to assume that this pair may come first beforehand in which Orville also comes on before Kelly. Nancy also appears before Leslie and since each pair has a female and a male, it is safe to assume that Orville and Nancy perform second while Jack and Leslie perform first and Kelly and Marty perform last.

How large must a group of people be in order to guarentee that there are at least two people in the group whose birthdays fall in the same month
Answer:
13
Step-by-step explanation:
This problem is an example of pigeonhole principle which states that If n+ 1 objects are placed into n boxes, then some box contains at least 2 objects.
Here no. of months in a year are boxes n = 12.
Therefore number of objects( people) = n+1= 13.
Then,at least two people in the group whose birthdays fall in the same month.

The world record for the men’s 10000 meters was 26 minutes 17.53 seconds held by kenenisa bekele of Ethiopia. What was his average speed throughout the race?
Answer:
6.33 m/s
Step-by-step explanation:
Given that,
The world record for the men’s 10000 meters was 26 minutes 17.53 seconds.
Distance = 10000 m
Time, t = 26 minutes 17.53 seconds = 1577.53 s
We need to find the average speed throughout the race. It is equal to total distance divided by total time taken.
[tex]v=\dfrac{10000\ m}{1577.53\ s}\\\\=6.33\ m/s[/tex]
So, the average speed is 6.33 m/s.

Is the length of DE is shown, what other length can you determine for this diagram? Help me please
Answer:
Another length of this diagram FE=12.
Step-by-step explanation:
According to diagram
In triangle FED, EM is perpendicular bisector of FD.
In ΔFED, EM ⊥ FD and FM=MD
In ΔFME and ΔDME
FM=DM (Given)
∠FME=∠DME (each 90°)
ME=ME (Common)
ΔFME ≅ ΔDME (By SAS congruence property)
Therefore, FE≅DE (by CPCT)
But DE=12
So, FE=12
Thus, Another length of this diagram FE=12.
Step-by-step explanation:
A teacher selects a student at random from his class of 20 students every week for 20 consecutive weeks. There are 8 girls and 12 boys in the class. What is the probability that there are exactly 12 weeks in which a girl is selected
Answer:
The value is [tex]P(X = 12) = 0.0356 [/tex]
Step-by-step explanation:
From the question we are told that
The number of boys in the class is [tex]b = 12[/tex]
The number of girls in the class is [tex]g = 8[/tex]
The total number of students is is n = 20
The number of weeks is N = 20
The probability of selecting a girl is mathematically represented as
[tex]p = \frac{8}{20}[/tex]
=> [tex]p = 0.4[/tex]
The probability of not selecting a girl is mathematically represented as
[tex]q = 1- \frac{8}{20}[/tex]
=> [tex]q =0.6[/tex]
Generally the selection of students from the class follows a binomial distribution
i.e
[tex]X \~ \ \ \ B(n , p)[/tex]
and the probability distribution function for binomial distribution is
[tex]P(X = x) = ^{N}C_x * p^x * (q)^{n-x}[/tex]
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the probability that there are exactly 12 weeks in which a girl is selected is mathematically represented as
[tex]P(X = 12) = ^{20}C_{12} * 0.4^{12} * (0.6)^{20-12}[/tex]
[tex]P(X = 12) = 125970 * [1.678*10^{-5}]* 0.016796 [/tex]
=> [tex]P(X = 12) = 0.0356 [/tex]

On average, carwash location 1 washed 145 cars daily, carwash location 2 washed 211 cars daily, and car wash location 3 washed 184 cars daily. Approximately how many cars were washed over a 4-day period?
Answer:
In 4 days approx. 1527 cars were washed over a 4-day period.
Step-by-step explanation:
To find out how many cars were washed in these 3 washes over 4 days as long as they stay at the same constant number, simply multiply the number of cars each wash washes a day by 4 then add it all together. See below:
145 x 4 = 580
211 x 4 = 211
184 x 4 = 736
580 + 211 + 736 = 1527
So, in 4 days approx. 1527 cars were washed over a 4-day period.

find the value of x to the nearest tenth
Answer:
x = 41.2
Step-by-step explanation:
Assuming the dotted line at the top is parallel to the segment with length x, it follows from the alternate interior angles theorem that the interior angle of the triangle (marked in diagram) is also 27º.
Using SOH-CAH-TOA, we get that tan(27º) = 21/x, so x = 21/tan(27º), which is approximately equal to 41.2.
Solve for y in the following equation.
Answer:
[tex] y = \frac{z^2 - x}{2} [/tex]
Step-by-step explanation:
Given:
[tex] \sqrt{x + 2y} = z [/tex]
Required:
Solve for y (make y the subject of the formula)
SOLUTION:
[tex] \sqrt{x + 2y} = z [/tex]
Square both sides
[tex] (\sqrt{x + 2y})^2 = z^2 [/tex]
[tex] x + 2y = z^2 [/tex]
Subtract both sides by x
[tex] 2y = z^2 - x [/tex]
Divide both sides by 2
[tex] y = \frac{z^2 - x}{2} [/tex]

Answer:
B
Step-by-step explanation:
You would need to convert the fractions to a denominator of 15 because it's the closest denominator for both.
So 1 and 2/5 can be changed to 1 and 6/15
And 1 and 1/3 can be changed to 5/15
So what you do is multiply both the numerator and denominator by how much you need to multiply to get to 15 and the denominator.
You would then add the fractions, leaving the answer to be 2 and 11/15
So for example 2 * 3 = 6 and 5 * 3 = 15, meaning the fraction would be 6/15
