What are 3 fractions that are greater than 1/2 but less than one (50 points)

Answers

Answer:

2/3, 3/4, and 4/5.

Step-by-step explanation:

Three fractions that are greater than 1/2 but less than 1 are 2/3, 3/4, and 4/5.

To write three fractions that are greater than 1/2 but less than 1, the following calculation must first be performed:

1/2 = 0.5

Therefore, the fraction must have a value between 0.5 and 1.

2/3 = 0.666

3/4 = 0.75

4/5 = 0.80

Therefore, three fractions that are greater than 1/2 but less than 1 are 2/3, 3/4, and 4/5.

Answer:

2/3, 3/4, and 4/5

which polynomial can be simplified to a difference of squares? 10a2 3a – 3a – 16 16a2 – 4a 4a – 1 25a2 6a – 6a 36 24a2 – 9a 9a 4

Answers

For the polynomial: 10a^2 + 3a - 3a - 16 = 10a^2 - 16 but 10a^2 is not a perfect square hence does not simplify to a difference of two squares. For the polynomial: 16a^2 - 4a + 4a - 1 = 16a^2 - 1 = (4a - 1)(4a + 1). This polynomial simplifies to a difference of two squares. For 25a^2 + 6a - 6a + 36 = 25a^2 + 36. This ia a sum of two squares and not a difference of two squares. For 24a^2 - 9a + 9a + 4 = 24a^2 + 4. This ia a sum of two squares and not a difference of two squares.

The polynomial 16a² - 4a + 4a - 1 can be simplified to a difference of squares

What is a polynomial?

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

The difference of two squares is given by:

a² - b² = (a + b)(a - b)

Hence:

16a² - 4a + 4a - 1 = 4a(4a - 1) + 1(4a - 1)

= (4a + 1)(4a - 1)

The polynomial 16a² - 4a + 4a - 1 can be simplified to a difference of squares

12 divided by 8 into a mixed number

Answers

Hi there, to turn a fraction into a mixed number we divide the numerator by the denominator, write down the whole number, and then right down the remainder. In this case, we divide the numerator which is 12 and 8 which is the denominator which is 8, 12 divided by 8 equals 1.5, 1 will be the whole number, 4 will be the numerator, and 8 will be the denominator. So, we get 1 4/8. Therefore, 12/8 as a mixed number is 1 4/8.

1 side of a square room measures 18 feet. How many square yards of carpet are necessary to carpet the room

Answers

18 ft= 54 yds.
a square has four equal sides, so 54 times 54 equals 2,916
Your answer is 2,916 square yards

First, let's convert the measurement from feet to yards. We know that 1 yard equals 3 feet. So, to find the length in yards, we need to divide the given length in feet by 3.

This gives us 18 feet ÷ 3 = 6 yards. So, one side of the room measures 6 yards.

Next, to find the area of the room in square yards, we need to remember that the formula for the area of a square is side length squared (side^2) because all sides of a square are equal.

So, we calculate 6 yards (the converted side length) multiplied by itself:

6 yards × 6 yards = 36 square yards.

Therefore, 36 square yards of carpet are necessary to fully carpet the room.

Answer: 36 square yards

The mean of a population being sampled is 64, and and the standard deviation is 6.If the sample size is 50, the standard error of the mean is . (Round off your answer to the nearest hundredth.)

Answers

Given:
mean of the population being sampled = 64
standard deviation = 6
sample size = 50

standard error of the mean=standard deviation of the original distribution
root of the sample size

standard error of the mean = 6 / √50
standard error of the mean = 6 / 7.07
standard error of the mean = 0.848 or 0.85

The mean of a population being sampled is 64, and and the standard deviation is 6.

If the sample size is 50, the standard error of the mean is 0.85. (Round off your answer to the nearest hundredth.)
