Alenkinab [10]

Answer:

32\:\mathrm{in}

Step-by-step explanation:

The area of a triangle is given by A=\frac{1}{2}\cdot b\cdot h.

Substituting given values, we have:

240=\frac{1}{2}\cdot b\cdot 15,\\480=15b,\\b=\frac{480}{15}=\boxed{32\:\mathrm{in}}

Vlad1618 [11]

Answer:

Explained below.

Step-by-step explanation:

The complete question is:

Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior. He records how long they slept (in hours), how many bananas they ate, gender, age (in years), and the specific breed of monkey.

(a) What are the individuals in this data set?

(b) Identify the variables that were recorded, and indicate whether each one is categorical or quantitative?

Solution:

(a)

The term "individuals", in statistics, implies or denotes the objects or people included in a statistical study.

In this case it is provided that Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior.

So, the "individuals" in this data set are the monkeys.

(b)

Categorical variables belong to a certain category or label values. Such as gender of a person, state from which a person is from, color of the marble and so on.

Quantitative variables are those variables that assume numerical values and represent some sort of measurement. Such as height, weight, annual income of the people working at the same place and so on.

In this case the variables are:

Number of bananas the monkeys ate - Quantitative variable

Gender - Categorical variable

Age (in years) -  Quantitative variable

Specific breed of monkey - Categorical variable

<h3>What Long division method?</h3>

Long division is a method for dividing one large multi digit number into another large multi digit number.

Given:

f(x)=  x²+2x+1

g(x)= x+1

The steps to divide the polynomial is :

  • Divide the leading term of the dividend by the leading term of the divisor: x²/x=x.
  • Multiply it by the divisor: x(x+1)=x²+x.
  • Subtract the dividend from the obtained result: (x²+2x+1)−(x²+x)=x+1.
  • Divide the leading term of the obtained remainder by the leading term of the divisor: x/x=1.
  • Multiply it by the divisor: 1(x+1)=x+1.
  • Subtract the remainder from the obtained result: (x+1)−(x+1)
