Select the correct answer from each drop-down menu. Wayne and Winston collect old coins. Winston has 8 fewer coins than Wayne ha

s. If you add 4 times the number of coins Wayne has and 3 times the number of coins Winston has, the sum is 375. This system of linear equations relates the number of coins Wayne has (x) and the number of coins Winston has (y). y = x − 8 4x + 3y = 375 The best method to solve this system of equations is . Wayne has coins, and Winston has coins.

What is the best estimate for 591.3 divided by 29
Katena32 [7]

Answer:

  about 20

Step-by-step explanation:

The numbers round to 600/30 = 20, which is a reasonable estimate.

You can refine this by doing the next step of long division:

  29×20 = 580

Subtracting this from 591.3 give 11.3, so the fraction is ...

  11.3/29 ≈ 10/30 = 1/3

A better estimate is 20 1/3.

_____

A calculator tells you the quotient is about 20.3897.

Below are the jersey numbers of 11 players randomly selected from a football team. Find the​ range, variance, and standard devia
padilas [110]

Answer:

Option(A) is correct

Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

Step-by-step explanation:

The given data set in the question are ;33, 29, 97, 56, 26, 78, 83, 74, 65, 47, 58

the range can be determined by finding the highest value and subtract it to the lowest value. In this case the values are:

Highest = 97

Lowest = 71

Range = highest value - Minimum value

Range = 97 - 26 = 71

Range= 71

mean of the data is the summation of all the numbers in the data set divided by the number of given samples.

Mean = (33 + 29 + 97 + 56+ 26 + 78 + 83 74+ 65 + 47 + 58)/11

= 647/11

Mean value =58.7

Now to find the variance of the data set by using below formular

σ²=[ (xᵢ -mean)²]/n-1

[(33-58.7)² +(29-58.7)²+( 97-58.7)²+( 56-58.7)²+( 26 -58.7)²+(78-58.7)²+( 83 -58.7)²+(74-58.7)²+( 65-58.7)²+( 47 -58.7)²+(58 -58.7)²]/10

Variance=546

Now, we will calculate standard deviation by taking square root over variance

σ =√(variance)

σ =√(546)

Standard deviation= 23.4

Hence, the range is 71 ,variance is 546 and standard deviation is 23.4 therefore,

Option A is the answer that is Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.
