Explain how you would order from least to greatest three numbers that include a positive number a negative number and a zero

1 answer:

4 0

The negative numbers would be first, but instead of seeing if the number was smaller, you'd see if it was bigger, such as -4 is less than -3. Then the 0 would be added to the sequence, then the positive numbers, such as 2 is less than 5. An example would be
-4, -3, 0, 2, 5

HELP ASAP PLEASE

Roman55 [17]

Answer:

a. median is 8

b. first quartile is 7

c. third quartile is 9.5

d. below

e. below

Step-by-step explanation:

7, 10, 10, 6, 7, 8, 8, 7, 9.

Place number in order least to greatest

6, 7, 7, 7, 8, 8, 9, 10, 10

a. What is the median?

The median is the middle number in a data set

number of terms in data set (n) + 1 / 2 =

9 + 1 / 2 = 10 / 2

6, 7, 7, 7, 8, 8, 9, 10, 10

The median is 8

b. What is the first quartile?

Q1 is the central point between the smallest score and the median

6, 7, 7, 7

since there is even number of data points you find the average,

7 + 7 / 2 = 14 / 2 = 7

c. What is the third quartile?

Q3 is the central point between the median and the largest score

8, 9, 10, 10

since there is even number of data points you find the average,

9 + 10 / 2 = 19 / 2 = 9.5

d. Draw a box plot of the data.

below

e. Write two conclusions about the data shown in the box plot.

There are no outliers with a minimum of 6 and a maximum of 10. The Interquartile Range is 2.5 (9.5 - 7)

Davis Electronics manufactures a certain type of radio that requires 18 working resistors per radio. If one out of 22 resistors

REY [17]

Since One Radio in Davis Electronics requires 18 working resistors, then 2,145 radios will require $18\times2145=38610$ resistors.

Now we know that one out of 22 resistors is defective. This means that the number of non defective or perfect resistors in a set of 22 resistors is 21.

So, obviously, if we pick a set of 40,370 resistors then the set of working resistors we will get is $40370\times \frac{21}{22} =38535$ .

As can be clearly seen from the above calculations the required amount of working resistors is 38610 and the amount of working calculators available to us is 38535.

Thus, since the required amount of working resistors is greater than the amount of working resistors available, 40,370 resistors are not enough to assemble 2,145 radios.

tanya has 3 red marbles 7 blue marbles and 9 green marbles what expression can be used to to find the percent of tanyas marbles

stepladder [879]

Answer: 3+7+9=19.....7/19=0.368 percent. Move the decimal two places to the right and round up for 37%

Step-by-step explanation:

Add all the colors together to get a TOTAL amount of ALL marbles.

The total amount for this problem is 19 (3+7+9=19)

The blue amount of marbles is given as 7.

Divide the blue amount (7) by the total amount (19) for the specific percentage for that color.
