Answer 1

Answer:

Answer:

2 x ? = 7 1/2 and ? x 2 = 7 1/2

Step-by-step explanation:

This is the answer because it didn't show the answer so all you have to figure out is the multiplication problem that goes with the division problem. So 2 x ? = 7 1/2 and ? x 2 = 7 1/2 you don't have to include the answer all you have to include is where the answer will do if you DID have the answer. These two are correct because the multiplication number can go in any order.

I know this might not be the best step-by-step explanation ever but I truly tried but the answer is correct.

At Billy's preschool, they have a total of 25 bicycles and tricycles. Among them all, there are 57 wheels. How many of each are there?

Answers

let x be the number of bicycles and y the number of tricycles. x+y=25 (1) and 2x+3y=57 (2). Multiplying (1) by 2, you have 2x+2y=50. Doing (2)-(1) gives y=7. Therefore, x=25-7=18. There are 18 bicycles and 7 tricycles.

The data set represents the number of rings each person in a room is wearing.0, 2, 4, 0, 2, 3, 2, 8, 6

What is the interquartile range of the data?

2
3
4
6

Answers

Answer:

the interquartile range of the data is:

Step-by-step explanation:

We are given a data set as:

0, 2, 4, 0, 2, 3, 2, 8, 6

On arranging the data in the ascending i.e. increasing order is given by:

0 0 2 2 2 3 4 6 8

The minimum value of data set=0

Maximum value of data set is: 8

Range of data set= Maximum value-Minimum value

i.e. Range= 8-0

i.e. Range= 8

Also, Median of set is the central tendency of the data and is given by:

Median= 2

Lower set of data is:

0 0 2 2

Hence, The median of lower set of data is the lower quartile or first quartile.

i.e. $Q_1$

Hence, $Q_1=(0+2)/(2)\n\n\nQ_1=(2)/(2)\n\n\nQ_1=1$

Hence, Lower quartile=1

Similarly upper set of data is:

3 4 6 8

Hence, The median of upper set of data is the upper quartile or third quartile.

i.e. $Q_3$

Hence, $Q_3=(4+6)/(2)\n\n\nQ_3=(10)/(2)\n\n\nQ_3=5$

Hence, Upper quartile=5

Hence, the interquartile range(IQR) is given by:

IQR=Upper quartile-Lower quartile

IQR=5-1

IQR=4

If the data set represents the number of rings each person is wearing, being: 0,2,4,0,2,3,2,8,6, the interquartile range of the data is 2. Being, 4 as the Q1, 3 as the Q2 or median, and 6 as the Q3. Where the formula of getting the interquartile range is IQR= Q1-Q2.

Two quadratic functions are shown.Function 1:

x g(x)
−2 13
−1 7
0 3
1 7

Which function has the least minimum value and what are its coordinates?
Function 1 has the least minimum value and its coordinates are (−1, 4).
Function 1 has the least minimum value and its coordinates are (0, 7).
Function 2 has the least minimum value and its coordinates are (−1, 7).
Function 2 has the least minimum value and its coordinates are (0, 3).

Answers

The right answer for the question that is being asked and shown above is that: "Function 2 has the least minimum value and its coordinates are (0, 3)." the function that has the least minimum value and what are its coordinates is that Function 2 has the least minimum value and its coordinates are (0, 3).
