Answer:
15¢
Step-by-step explanation:
$12.75 - 6 × $2.10 = $12.75 - $12.60 = $0.15
Answer: 15 cents
10 times greater.The 6 on Billy Joe's paper represents 600 and the 6 on Reginald's paper represents 6,000. 600 x 10 = 6,000 or 6,000 / 600 = 10
Answer:
45.712
Step-by-step explanation:
We need to find the Zscore of the area of 15 percent of the distribution ; using a Z table or calculator ;
Zscore of 15% of the distribution is : - 1.036
Using the Zscore formula :
Zscore = (x - mean) / standard deviation
Where, x = score
-1.036 = (x - 54) / 8
Cross multiply
-1.036 * 8 = x - 54
-1.288 = x - 54
x = - 8.288 + 54
x = 45.712
1:
A - actually not true, a probability plot would be better
B - not true, since exact values are plotted a box-and-whisker would be better
C - true (that's what a histogram does)
D - True (You can get the measures of central tendency quickly)
2:
A - true
B - False - those are easily found
C - False - They are arranged on the x-axis
D - True - see above
