Since every hour, a vendor sells to 1500 customers, we multiply by hours, like this:
1500 * 4 = 6000.
Then we divide 50000/6000, and that would give us 8.33333333, and we round that to the next number which is 9, and that's the answer.
Answer: 9 vendors.
Hope this helped! c:
Using Multiplication, There are 9 vendors are needed to ensure that each fan can be served during the game.
What is Multiplication?Multiplication is to "increase a number by the number of times mentioned".
According to the question,
Number of fans expected to attend a football game = 50,000
Number of customer to be served = 1,500per hour
To find number of customer to be served for 50,000 fans
The game has to be last for 4 hours.
Formula : 1 vendor is to sell 1,500 customer per hour
4*1500 = 6000
A vendor has to sell 6000 customers in 4 hours.
In order to find the number of vendors have to sell 50,000 customers in 4 hours
Let 'x' be the number of vendors
To find the number of vendors only if we divide 50,000 by 6000
=[tex]\frac{50,000}{6000}[/tex] = 8.333 ≈ 9
Hence, there are 9 vendors are needed to ensure that each fan can be served during the game.

Nikolai has a jar filled with 120 marbles. he has 72 red marbles, 17 blue marbles, 13 green marbles, and 18 purple marbles. what is the probability that he will randomly select a blue marble, without replacement, and then a purple marble from the jar
The probability of selecting a blue marble followed by a purple marble from a jar containing 120 marbles with different colors is approximately 2.2%.
The probability of grabbing a blue marble and then a purple marble is determined by multiplying the probability of grabbing a blue marble first and the probability of grabbing a purple marble second. Here's the calculation:
Probability of selecting a blue marble first: 17/120
Probability of selecting a purple marble second (after one blue marble is already taken out): 18/119
Multiplying the probabilities: (17/120) * (18/119) ≈ 0.022, or 2.2%

Sandy releases a javelin 1.6 m above the ground with an initial vertical velocity of 25 m/s. How long will it take the javelin to hit the ground?
Using a quadratic function, it is found that it will take 5.17 seconds for the javelin to hit the ground.
What is the quadratic function for a projectile's height?Considering meters as the measure of height, it is given by:
h(t) = -4.9t² + v(0)t + h(0).
In which:
v(0) is the initial velocity.h(0) is the initial height.In this problem, we have that v(0) = 25, h(0) = 1.6, hence:
h(t) = -4.9t² + 25t + 1.6
It hits the ground when h(t) = 0, hence:
-4.9t² + 25t + 1.6 = 0
4.9t² - 25t - 1.6 = 0.
Which is a quadratic function with coefficients a = 4.9, b = -25, c = -1.6. Hence:
[tex]\Delta = (-25)^2 - 4(4.9)(-1.6) = 656.36[/tex]
[tex]x_1 = \frac{25 + \sqrt{656.36}}{9.8} = 5.17[/tex]

A-Town wants to know the number of cell phones in each household the town divides the population up by neighborhood and surveys a random number of households and eat what type of survey is this
A-Town is conducting a survey using a random sample method by dividing the population into neighborhoods and surveying random households in each, which ensures each household has an equal chance of being selected and provides a representative sample.
Explanation:A-Town's approach to determining the number of cell phones in each household through a survey is an example of a random sample. The method involves dividing the population into neighborhoods and surveying a random selection of households within each area. This technique helps to ensure that every household has an equal chance of being selected, which should provide a representative sample of the town's population. Such methods are necessary to obtain reliable data that reflects the true distribution and characteristics of the target population without regional bias.
Using a representative sample is crucial in research and polling to measure accurately public opinion or collect data on phenomena. As in the given example where the market research firm surveys 500 randomly selected residents to estimate the percentage of adults with cell phones, the firm employs statistical measures like confidence intervals to infer about the entire population's cell phone ownership based on the sample data. Moreover, the concept of probability sampling is also important for achieving a sample that can be generalized to the whole population with reasonable accuracy.

Jake is younger than Sophie. Sophie is 14 years old. Write an inequality that compares Jake's age in years, (j), to Sophie's age.
To express that Jake is younger than Sophie who is 14, we use the inequality j < 14, where j symbolizes Jake's age in years.
Explanation:The question is asking for an inequality that represents Jake's age compared to Sophie's age. Since we are told that Jake is younger than Sophie and Sophie is 14 years old, we can use an inequality symbol to express this relationship. The appropriate inequality is j < 14, where j represents Jake's age in years. The symbol < means 'less than,' which correctly compares Jake's age to Sophie's, indicating that Jake's age is less than 14 years.

The function h=−16t2+26t models the height h (in feet) of the dolphin after t seconds. after how many seconds is the dolphin at a height of 5 feet? round your answers to the nearest tenth.
Answer:
The dolphin is at height 5 feet after 1.40 seconds or 0.228 seconds.
Step-by-step explanation:
Given : The function [tex]h=-16t^2+26t[/tex]models the height h (in feet) of the dolphin after t seconds.
To Find: After how many seconds is the dolphin at a height of 5 feet?
Solution:
Function: [tex]h=-16t^2+26t[/tex]
h is the height
t is the time
Now we are supposed to find After how many seconds is the dolphin at a height of 5 feet
Substitute h = 5
So, [tex]5=-16t^2+26t[/tex]
[tex]16t^2-26t+5=0[/tex]
[tex]16t^2-26t+5=0[/tex] ---1

a = 16
b = -26
c=5
Substitute the values in the quadratic formula.
[tex]x = \frac{-(-26)\pm\sqrt{(-26)^2-4(16)(5)}}{2(16)}[/tex]
[tex]x = \frac{26\pm 18.86796}{32}[/tex]
[tex]x = \frac{26+18.86796}{32},\frac{26-18.86796}{32}[/tex]
[tex]x = 1.4021,0.2228[/tex]
Thus the dolphin is at height 5 feet after 1.40 seconds or 0.228 seconds.
The dolphin is at a height of 5 feet at 0.2 second and 1.4 seconds.

The equation of a parabola is 1/32 (y−2)2=x−1 .
What are the coordinates of the focus?
(1, 10)
(1, −6)
(−7, 2)
(9, 2)
The given equation of parabola is
[tex] \frac{1}{32} (y-2)^2 = x-1 [/tex]
Which can also be written as
[tex] x = \frac{1}{32} (y-2)^2 +1 [/tex]
Here vertex (h,k) is (1,2)
And value of a is
[tex] a = \frac{1}{32} [/tex]
Formula of focus is
[tex] (h+ \frac{1}{4a} , k) [/tex]
Substituting the values of h,k and a, we will get
[tex] (1+ \frac{1}{4*(1/32) } , 2} = (1+ 8,2) = (9,2) [/tex]
Therefore the correct option is the last option .
Answer: The correct option is (D) (9, 2).
Step-by-step explanation: We are given to find the co-ordinates of the focus for the following parabola:
[tex]\dfrac{1}{32}(y-2)^2=x-1~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that the standard form equation of a parabola is
[tex](y-k)^2=4p(x-h),[/tex]
where the co-ordinates of the focus are (h+p, k).
From equation (i), we have
[tex]\dfrac{1}{32}(y-2)^2=x-1\\\\\\\Rightarrow (y-2)^2=32(x-1)\\\\\Rightarrow (y-2)^2=4\times 8(x-1).[/tex]
Comparing the above equation with the standard form equation of the parabola, we get
h = 1, k = 2, and p = 8.
Therefore, the co-ordinates of the focus are
[tex](h+p,k)=(1+8,2)=(9,2).[/tex]
Thus, option (D) is CORRECT.

How many arrangements are possible using the letters in the word fuzzy if each letter "z" is distinctly different than the other? how many arrangements are possible if the letter "z" is interchangeable with the other? explain your reasoning?
Case 1: If the letter z is distinctly different
If we have the letter z which is distinctly different than the other "z", then we have five letters in the word F U Z Z Y and the number of arrangements would be = 5*4*3*2*1 =5! = 120 different arrangements
Case 2: If the letter Z is interchangeable
If the letter "Z" is interchangeable with the other "z" then we have 2 letters which cancel out each other that would be represented by 2*1 = 2! = 2
So, the number of arrangements in this case would be 5!/2! = 5*4*3*2*1/2*1 = 60 arrangements
