Answer:
Step-by-step explanation:
<u>Total number of oranges:</u>
- 0*5 + 1*8 + 2*6 + 3*6 + 4*3 + 5*2 = 60
<u>Number of baskets:</u>
- 5 + 8 + 6 + 6 + 3 + 2 = 30
<u>Mean of the distribution of oranges:</u>
Correct choice is d
Answer:
18, 19, and 20.
Step-by-step explanation:
Consecutive means beside. Numbers 2 and 3 are consecutive integers. Given this question, numbers 6, 8, and 9 could possibly be the answer. However, we don't know this, so let's represent the 6 as x, 7 as x+1. 9 is x+2. We know when these are added together the sum is 57, so 3x+3 should be 57. Now, solve as a normal algebraic question.
Answer: 1: row 3
2: Row 2
3: 6 and 10
Step-by-step explanation:I just did it
Let the side length of the original square be x, then
1/4 x^2 = (x - 3)^2
x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36
3x^2 - 24x + 36 = 0
3(x^2 - 8x + 12) = 0
x^2 - 8x + 12 = 0
x^2 - 2x - 6x + 12 = 0
x(x - 2) - 6(x - 2) = 0
(x - 6)(x - 2) = 0
x - 6 = 0 or x - 2 = 0
x = 6 or x = 2
but x cannot be 2 since the side length of the smaller square will be negative.
Therefore, the side length of the original square is 6 inches.
