Which fraction is in simplest form? 3/9, 5/12, 6/14, 4/22

The wheels of the tricycle are turning approximately 7.68 revolutions per second.

To convert the speed from feet per hour to revolutions per second, we need to know the circumference of the wheels. The circumference of a circle with radius 5 inches is 2 * pi * 5 = 10 * pi inches. To convert the speed from feet per hour to inches per second, we multiply by 12, since there are 12 inches in 1 foot. So, the speed in inches per second is 20 * 12 = 240 inches per second. The number of revolutions per second is then equal to the speed divided by the circumference:

240 inches per second / (10 * pi inches) = 240 / (10 * pi) revolutions per second

Rounding to the nearest hundredth:

240 / (10 * pi) ≈ 24 / (pi) ≈ 7.68 revolutions per second

So, the wheels are turning approximately 7.68 revolutions per second.

Many children develop the ability to do simple arithmetic problems during their early childhood years, typically between the ages of 4 and 6. Correct option is a).

During this time, children start to understand basic mathematical concepts such as counting, addition, and subtraction. They may also begin to recognize and name numbers and use basic math vocabulary. However, it's important to note that every child develops at their own pace and some may show these skills earlier or later than others. It's also important for parents and caregivers to provide opportunities for children to practice and reinforce these skills through activities such as counting objects, playing number games, and solving simple math problems.

Answer:

full question Grace is an hourly employee, and the line that models her total pay in dollars

as it relates to the number of hours she has worked has a slope of 45 and a y

intercept of 35. Which statement is true?

A. Grace's wage is $35 an hour, and it appears that she received a

signing bonus of $45.

B. Grace's wage is $35 an hour, but it appears that she received no

signing bonus.

C. Grace's wage is $45 an hour, and it appears that she received a

signing bonus of $35.

D. Grace's wage is $45 an hour, but it appears that she received no

signing bonus.

Step-by-step explanation:

if x is the amount of hours worked, 45 is the slope and the y intercept is 35.

A linear equation has the form of y = ax + b, where a is the slope and b is the y-intercept, then the equation that we have is:

y = 45*x + 35

this means that she wins $45 per hour, and has a plane amount of $35, indiferent of the amount of hours worked.

Then the correct answer is

C) Grace's wage is $45 an hour, and it appears that she received a  signing bonus of $35.

There are four possible three-letter arrangements that Amy can form using the letters from the word "dice" without repeating any letters. To form a three-letter arrangement using only letters from the word "dice" without repeating any letters, we can use the formula for combinations.

The formula is given by nCr = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to be chosen.
In this case, n = 4 (the total number of available letters) and r = 3 (the number of letters to be chosen for the arrangement).
5. Substituting these values into the formula, we get \(4C_{3}\) = 4! / (3!(4-3)!) = 4! / (3!1!) = (4 * 3 * 2) / (3 * 2 * 1) = 4.

The distance formula can be used to calculate the distance between the coordinate points as follows;

A. 2·√(10), and √(65)

B. √(13), and 4·√2

C. 3·√(13), and √(241)

D. 9, and 2·√(26)

E. 8·√5, and √(13)

F. 2·√5, and √(181)

G. 7·√2, and 4·√5

H. √(261), and √(178)

I. 2·√(17), and √(41)

The distance, d, between two points on the coordinate plane (x₁, y₁), and (x₂, y₂), can be found using the formula; d = √((x₂ - x₁)² + (y₂ - y₁)²)

The distances between the coordinate points are therefore;

A. The distance between (2, -6) and (4, -12), d can be found using the distance formula as follows;

d = √((4 - 2)² + (-12 - (-6))²) = √(4 + 36) = √(40)

√(40) = 2·√(10)

The distance between (8, 0) and (4, 7)

d = √((8 - 4)² + (0 - 7)²) = √(65)

The further distances obtained using an online tool are as follows;

B. The distance between (-3, 4) and (-6, 6) = √(13)

The distance between (-3, 2) and (1, 6) = 4·√2

C. The distance between (9, 5) and (0, -1) = 3·√(13)

The distance between (8, -6) and (-7, -2) = √(241)

D. The distance between (-3, 8) and (6, 8) = 9

The distance between (-8, 7) and (2, 9) = 2·√(26)

E. The distance between (10, -10) and (2, 6) = 8·√5

The distance between (-10, -8) and (-7, -6) = √(13)

F. The distance between (3, 6) and (7, 4) = 2·√5

The distance between (-1, 6) and (8, -4) = √(181)

G. The distance between (9, 1) and (2, 8) = 7·√2

The distance between (-5, 10) and (-1, 2) = 4·√5

H. The distance between (-4, -13) and (11, -7) = √(261)

The distance between (1, 2) and (4, -11) = √(178)

I. The distance between (-11, -5) and (-9, 3) = 2·√(17)

The distance between (10, 8) and (5, 4) = √(41)

Therefore, the possible arrangement of the letters is as follows;

Step-by-step explanation:

The correct statement is: provided that the sample size is reasonably large (for any population).

The Central Limit Theorem states that, under certain conditions, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution.

These conditions include a random sample from the population and a sufficiently large sample size (typically, n > 30 is considered large enough).

Therefore, the Central Limit Theorem is important because it allows us to make inferences about the population mean using the normal distribution, even if we do not know the population distribution.

This is useful in many applications of statistics, including hypothesis testing, confidence intervals, and estimating population parameters

The probability of quarterback completing less than 9 of 14 passes is \(0.8810\).

We will determine mean and standard deviation of the quarterback's completion rate over 14 passes.

The mean would be:

= 14 * 0.45

= 6.3

The standard deviation would be:

= sqrt(14 * 0.45 * (1 - 0.45))

= sqrt 3.465

= 1.8614510469

= 1.86

We will standardize the value of 8.5 (between 8 and 9 completions).

z = (x - mean) / std dev

z = (8.5 - 6.3) / 1.86

z = 1.18279569892

z = 1.18

Using a standard normal distribution table, we find probability of z-score less than 1.18 is 0.8810.
