3/4 is not less than 2/10.
3/4 = 15/20
2/10 = 4/20
15/20 > 4/20
Answer:
52.4 cm
Step-by-step explanation:
Circumference of a circle = 2πr
Radius, r = diameter / 2
= 17 cm / 2
= 8.5 cm
π = 3.14
Circumference of a circle = 2πr
= 2 × 3.14 × 8.5
= 53.38 cm
Approximately 52.4 cm
For miles... 0.333333 Miles per Mile
The distribution of the number of occurrences of the letter t on the pages of a book is found to be a normal distribution with a mean of 44 and a standard deviation of 18. If there are 500 pages in the book, which sentence most closely summarizes the data?
A. The letter t occurs less than 26 times on approximately 170 of these pages.
B. The letter t occurs less than 26 times on approximately 15 of these pages.
C. The letter t occurs more than 26 times on approximately 420 of these pages.
D. The letter t occurs more than 26 times on approximately 80 of these pages.
.Answer:
<span>mean = 44 </span>
<span>sd = 18 </span>
<span>that means that "26" is 1 s.d. down, or at the 16th %ile </span>
<span>so, there is a .16 chance that "t" will occur less than 26 times on any single page. </span>
<span>consequently, there is a .84 chance that it will occur more than 26 times on any single page. </span>
<span>Using that information, and knowing that 16% of 500 is 80, and 84% of 500 is 420, can you see where "C" is correct? </span>
