How can I create a word problem with the following expressions 15+2d 200-4m

1 answer:

6 0

For the first expression
15 + 2d
A possible word problem would be this:
A person saves $2 per day of money. Before he started saving, he had $15 dollars set aside. Look for the expression that expresses the total amount of money saved in terms of the number of days passed

The second expression is
200 - 2m
A possible word problem would be this:
The distance from school to the park is 200m. A kid riding a bike is traveling at a speed of 2m/s from the school to the park. Write an expression for the distance remaining between the park and the kid.

Given a data set consisting of 33 unique whole number observations, its five-number summary is:

Lemur [1.5K]

Answer:

given a data set of 33 unique whole number observation,its five number sumary is [16, 29, 40 ,54, 67]

Step-by-step explanation:

The p-th percentile in an ordered (from low to high) data set is a value such that p% of the data is less than that value. The quartiles of a data set are the 25th, 50th and 75th percentiles. (The 25th percentile is usually called the first quartile, the 50th percentile is usually called the median, and the 75th percentile is usually called the third quartile.)

The formula for finding the location (or position) of the (approximate) pth percentile in an ordered (from low to high) data set is

L p=(n+1).p/100

For example, in the data set [2,4,6,8,10,12,14,16,18]

the (approximate) 60th percentile is located at position

L 60=(9+1).60/100=6

that is, the sixth data point (the value 12) is at the (approximate) 60th percentile.(Actually, only 55.6% of the data is below a 12.)

Martha is carrying her biology, science, and math textbooks. Her books weigh a total of 9 pounds. Her biology textbook weighs 3

Nata [24]

1 pound = 16 oz
Her books weigh 9 pounds or (9)(16)= 144 oz
Math Textbook= 40 oz
Biology textbook= 3 pounds or (3)(16)= 48 oz

Total weight of books - math textbook - biology textbook = science textbook
144-40-48 = 56oz
science textbook = 56oz

Answer:

Using technology or other resources, research the average distance that each planet is from the Sun (in kilometers). Once you have found the distance, create a chart showing each planet's distance from the Sun. The Sun itself will not receive a label since it is your starting point. For example, Mercury is located an average of 57,909,000 km from the Sun, so on the chart, Mercury would be labeled with a distance of 57,909,000. Use the example of the chart below to help you get started:

Planet Distance from Sun (in Km) Distance in scientific notation

Mercury 57,909,000 5.7909 X10^7

Venus 108.212.290.56 1.0821229056 X10^8

Earth 149,604,618.24 1.4960461824 X10^8

Mars 227,936,640 2.2793664 X10^8

Jupiter 778,412,020 7.7841202 X10^8

Saturn 1,433,442,700.8 1.4334427008 X10^9

Uranus 2,870,972,200 2.8709722 X10^9

Pluto 5,906,380,000 5.90638 X10^9

Among the eighth-graders in Micheal's school, 70% have siblings. The eighth-grade class is 5/6 the size of the seventh-grade cla

sladkih [1.3K]

OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:

0.7(total 8th graders) = 112

total 8th graders = 112/0.7

total 8th graders = 160

And since the number of 8th graders is 5/6 the size of the 7th grade class:

5/6(7th grade class) = 160

5(7th grade class) = 960

7th grade class = 192.

The correct answer is D) 192.
