Answer:
D. p ≤ 24
Step-by-step explanation:
The area of a piece of paper is 8.5·11 = 93.5 square inches, so the area of the bulletin board is that of ...
1728/93.5 ≈ 18.48
pieces of paper.
The solution is a number greater than 18, so selection D is the only viable choice.
___
The bulletin board is 24 inches high and 1728/24 = 72 inches wide. If Mrs. Wickowitz hangs the papers "sideways", then 3 of them will cover 25.5 inches vertically, and 7 of them will cover 77 inches horizontally. That's 3·7 = 21 whole sheets of paper. That, too, matches selection D.
Answer:
Let x be the number of left handed female students and let y be the number of left handed male students.
Then the number of right handed female students will be 5x and the number of right handed male students will be 9y. Since the total number of left handed students is 18 and the total number of right handed students is 122, the following system of equations must be satisfied.
x+y=18 and 5x+9y=122
Solving this system gives x=10 and y=8.
Thus, 50 of the 122 right handed students are female. Therefore, the probability that a right handed student selected at random is female is the fraction 50/122
which to the nearest thousandth is 0.410.
T is average time spend by shoppers in minutes
N average number of shoppers.
Here, shoppers/hour =84.
Hence r=

Given:
Number of flower pots = 6
To find:
The number of ways of the gardener to arrange the flower pots.
Solution:
Number of ways to arrange n items is n!.
So, the number of ways to arrange 6 pots is:
Therefore, there are total 720 ways of the gardener to arrange the flowerpots.
Slope = (8 - 0)/(0 - 4) = -2
y intercept b = 8
y = mx + b where m = - 2 and b = 8
So equation y = -2x + 8
Answer
D. last one
y = -2x + 8
