Where in town does our math teacher live? Is variability expected in the data? Statistical or Not

How many minutes does it take students in my class to get ready for school in the morning? Is variability expected in the data? Statistical or Not

Do all students in my class know what month it is? Is variability expected in the data? Statistical or Not​

Answers

1. yes - amount of water will vary bc people drink different amounts (typically like 4-10 cups?)
2. no - one exact piece of data data
3. yes - students spend different times (usually 0.5-2 hours)
4. no - students will almost all say yes, not expected to vary

Answer:

.5, 3, 8.5

Step-by-step explanation:

Divide the minutes by 2 since 6 is half of 12.Half of 1 is .5 or [tex]\frac{1}{2}[/tex]Half of 6 is 3Half of 17 is 8.5

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.

Step-by-step explanation:

Pages is directly proportional to Minutes

P = KM

k = P/M

when P = 6, M = 12.

k = 6/12

k = 0.5

_____________________

when M = 1

P = Km

P = 0.5×1 = 0.5

P = half a page.

______________________

when M = 6

P = 0.5× 6

P = 3 pages

______________________

when M = 17

P = 0.5×17 = 8.5

P = 8 and half pages

Hello I need help really quick, it's about percentages

Answers

30 students total, 12 boys

18/0.6 = 30
30-18=12
To check answer: 30*0.4 = 12

Answer:Let x be the total number of students in the class.

60% of x = ? (number of girls)

40% of x = 18 ( number of boys)

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 4 = 4. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - four minus one quarter = fifteen quarters.

The correct answer is 3/4 because 4 in fraction form is 4/4 and 4/4 minus 1/4 is 3/4.

Jaya's coach agreed to buy ice cream for all of the team members. Ice cream cones are $2.40 each. Write and solve an equation to find how many cones the coach can buy with $30.

Let n represent the number of cones the coach can buy.

n(2.4 + 4) = 30 ; n = 4.69

30 - 2.4 = n ; n = 27.6

MODELING REAL LIFE A softball has a volume of about 29 cubic inches. Find the radius of the softball. Round your answer to the nearest tenth.
The radius of the softball is about___inches.

Answers

the equation for volume is V=4/3 * pi * radius cubed.

Since we know 29 is the volume, the equation is 29=4/3 * pi * radius cubed.

To get the radius alone, first divide 29 by 4/3. You get 21 3/4 or 87/4 or 21.75 (whichever way).

Then divide 21.75 by pi (3.14). You get 6.92675159236

To get the radius alone, find the cubed root of 6.92675159236.

The answer is 1.90623543217, but I'd rounded to 1.91

Answer: 1.91

Step-by-step explanation: the equation for volume is V=4/3 * pi * radius cubed.

Algebra Mathematics
Question 1
Mr Brown has several models of famous people that each weigh the same. He decides to add in some new models that are of different weights to his old ones. In Room Number One, there are five old models along with a new model that weighs 240kg.
In Room Number Two, there are 3 old models along with a new model that weighs 510kg.

THE TOTAL WEIGHT OF THE MODELS IN ROOM ONE IS EXACTLY THE SAME AS THE TOTAL WEIGHT OF THE MODELS IN ROOM TWO.
What is the weight of an old model?

Answers

Answer:

135kg

Step-by-step explanation:

In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510.

the equation will be as: 5x + 240 = 3x + 510

move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240

which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510. the equation will be as: 5x + 240 = 3x + 510 move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240 which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

Without using a calculator, how can you determine in a fraction will repeat or terminate? Give an additional example of a fraction that repeats.

Answers

Step-by-step explanation:

A terminating decimal is a decimal that doesnt repeat, it just stops. A repeating decimal is a decimal that goes on forever, it never stops.

Answer:
To determine if a fraction will repeat or terminate, first you need to turn it into a decimal, then you can see if it repeats or terminates.

what is lim x → -1 ln x​

Answers

Answer:

Step-by-step explanation:

ln(∞) = ?

Since infinity is not a number, we should use limits:

x approaches infinity

The limit of the natural logarithm of x when x approaches infinity is infinity:

lim ln(x) = ∞

 x→∞

x approaches minus infinity

The opposite case, the natural logarithm of minus infinity is undefined for real numbers, since the natural logarithm function is undefined for negative numbers:

lim ln(x) is undefined

 x → -∞

So we can summarize

ln(∞) = ∞

The following data points represent last year’s revenue (in thousands of dollars) for each Herman Huagoes location

Answers

Answer:

Step-by-step explanation:

Since the median is defined as the data point that separates the lower half from the upper half.

Odd # data points: Middle value of an ordered pair with an equal amount of data points on both sides.Even # data points: Average of two middle values in an ordered pair with an equal amount of data points on both sides.

Since there is an even amount of data points, to find the median, identify the two middle values, which are 137 and 147. Then add them together and divide by 2 to compute the average →

137 + 147 / 2 → 284 / 2 → 142.

Thus the median revenue is
