Identify the horizontal asymptote of each graph

This is my question for homework. "You and some friends took a metal detector to the beach every day for a week to search for co

miss Akunina [59]

Answer:

The data is:

Number of nickels = 246

Number of dimes = 312

Number of quarters = 204.

Now, in your group there are N people.

Dividing the coins into N people, you find that each one received the same amount of each type of coin. Then the quotient between each number of coins and N must be a whole number.

Now, you can see that the 3 numbers are even, so we know that N must be even.

For example, if N = 2, we could divide the 3 numbers of coins and get an integer in each case, but this is worded as "You and some friends" so N must be larger than 2.

Try with the next even integer:

N = 4.

nickels: 246/4 = 61.5

61.5 is not an integer: Then N can not be 4.

The next even number is N = 6.

nickels: 246/6 = 41

dimes: 312/6 = 52

quarters: 204/6 = 34

In each case we have integers, this means that 6 divides the 3 numbers of coins, so each person can receive the same amount of coins.

The we can conclude with:

There are 6 persons in the group.

Each person gets 41 nickels, 52 dimes and 34 quarters.

Suppose that a company prints baseball cards. They claim that 30% of the cards feature rookies, 60% feature veterans, and 10% fe

liraira [26]

Answer:

H0: The distribution of players featured on the cards is 0.30 rookies, 0.60 veterans, and 0.10 All-Stars.

Ha: At least one of the proportions in the null hypothesis is false.

Step-by-step explanation:

On this case we need to apply a Chi squared goodness of fit test, and the correct system of hypothesis would be:

H0: The distribution of players featured on the cards is 0.30 rookies, 0.60 veterans, and 0.10 All-Stars.

Ha: At least one of the proportions in the null hypothesis is false.

And in order to test it we need to have observed and expected values. On this case we can calculate the Expected values like this

$E_{rookies}=50*0.3=15$

$E_{veterans}=50*0.6=30$

$E_{All stars}=50*0.1=5$

The observed values are not provided. The statistic on this case is given by:

$\chi^2 =\sum_{i=1}^n \frac{(O_i) -E_i}{E_i}$

And this statistic follows a chi square distribution with k-1 degrees of freedom on this case k=3, since we have 3 groups.

We can calculate the p valu like this:

$P(\chi^2 > \chi^2_{calculated})=p_v$

And if the p value it's higher than the significance level we FAIL to reject the null hypothesis. In other case we reject the null hypothesis.

Which of these pieces of data about a football team is considered numerical data?

Ivenika [448]

Answer:

1. Points scored

Step-by-step explanation:

A numerical data is defined as a data that is made up of numbers representing the quantity of a measurement. It is a measurable data such as weight or height, at it can be arranged in ascending or descending order as well as being able to provide an average.

The two types of numeric data are discrete and continuous data

A categorical data is made up of item labels, names or description, that are qualitative in their nature.

Information about a football team that is considered as numeric includes

1. Points scored

Which represents a quantifiable measurement that can be different with different teams and matches

2. Attendance this year.

To make punch for the class party, Mrs.Lui mixed 1 and 1/3 cups orange juice, 3/4 cup apple juice, 2/3 cup cranberry juice, and

andrew11 [14]

Answer: 3 1/2

Step-by-step explanation: First you have to convert the fractions so that they all have the same denominator. Using 12 will be the easiest. 1 and 1/3 equals 16/12 because 1/3 equals 4/12 and 1 equals 12/12. 3/4 equals 9/12. 2/3 equals 8/12. And 3/4 equals 9/12 again. 16/12 plus 9/12 plus 8/12 plus 9/12 equals 42/12. 42/12 in the simplest form would be 3 and 1/2, because 42 divided by 12 is 3.5.

River rambler charges $25 per day to rent a kayak. How much will it cost to rent a kayak for 5 days? Write and solve an equation

Sati [7]

Answer:

C=25d

Step-by-step explanation:

We write an equation where C or cost is my output and d or days is my input. I should be able to put in any number of days and find the cost. Let's gather some data:

River Ramble

Day 1 $25(1)=25 cost

Day 2 $25(2)=50 cost

Day 3 $25(3)=75 cost

Day d $25(d)=C.

Our equation is C=25d.
