Answer: (1) -5*(-10)=50

(2) 5*10=50

(2) 5*10=50

Answer: Use what they are telling.

a*b=50 (one integer times the other give you a product of 50. we're randomly calling these integers "a" and "b")

2a=b (one integer is twice the amount of the other. we're randomly selecting "b" to be twice the amount of "a")

plug in what we know

a*(2a)=50 (we replaced "b" with "2a" because we know from the info they gave us that b=2a)

now solve for "a"

a*2a=50

2a²=50

a²=50/2

a²=25

√a²=√25

a=5

which because 2a=b we know that b=10

a*b=50 (one integer times the other give you a product of 50. we're randomly calling these integers "a" and "b")

2a=b (one integer is twice the amount of the other. we're randomly selecting "b" to be twice the amount of "a")

Natasha is setting tiles along the baseboard in her bathroom. One side of the bathroom is 18 3/4 feet. Each tile is 1 1/2 feet long.

Well, I only know the answer to the first one (Sorry!!)

First you have to divide 7/4 by 7/8, or 7/4 x 8/7. That equals 56/28, an improper fraction. So, you divide 56 by 28, which equals 2.

So, it will take 2 days to process what was collected on Saturday.

What is the complete factorization of the polynomial function over the set of complex numbers? f(x)=x3−5x2+4x−20

Enter your answer in the box.

Answer: is the required factorization of f(x).

Step-by-step explanation:

To factor the expression we must first group the terms and then take out common from these groups

Taking common from first group and the 4 from second group we get:

Now, to factor in complex from we have to break term

As,

Also using identity

On solving

is the required factorization of f(x).

Answer:

f(x)=(x-2)(x+2)(x-5)

Step-by-step explanation:

f(x)=x³-5x²+4x-20 1. Just group randomly

f(x)=x²(x-5)+4(x-5) 2. Factor the groupings

f(x)=(x²+4)(x-5)

f(x)=(x-2)(x+2)(x-5) 3. Factor the difference of two squares

The monthly salaries of a sample of 100 employees were rounded to the nearest ten dollars. they ranged from a low of $1,040 to a high of $1,720. if we want to condense the data into seven classes, what is the most convenient class interval?

The most convenient class interval is $100 if the monthly salaries of a sample of 100 employees were rounded to the nearest ten dollars option (c) $100 is correct.

What is statistics?Statistics is a mathematical tool defined as the study of collecting data, analysis, understanding, representation, and organization. Statistics is described as the procedure of collecting data, classifying it, displaying that in a way that makes it easy to understand, and analyzing it even further.

The question is incomplete.

The complete question is:

The monthly salaries of a sample of 100 employees were rounded to the nearest $10. They ranged from a low of $1,040 to a high of $1,720. If we want to condense the data into seven classes, what is the most convenient class interval?

- a. $150
- b. $200
- c. $100
- d. $50

It is given that:

The monthly salaries of a sample of 100 employees were rounded to the nearest ten dollars. they ranged from

From the question for seven intervals starting from 1040

The First interval = $1040 to $1140

The second interval = $1140 to $1240

The third interval = $1240 to $1340

The fourth interval = $1340 to $1440

The fifth interval = $1440 to $1540

The sixth interval = $1540 to $1640

The seventh interval = $1640 to $1740

Thus, the most convenient class interval is $100 if the monthly salaries of a sample of 100 employees were rounded to the nearest ten dollars option (c) $100 is correct.

1720 - 1040 = 680

680/7 = 97.1

I would put them in intervals of 100

680/7 = 97.1
