Answer:
Step-by-step explanation:
7). (x + 3)(x + 7)
= x(x + 7) + 3(x + 7)
= x² + 7x + 3x + 21
= x² + 10x + 21
8). (4x + 2)(x - 2)
= 4x(x - 2) + 2(x - 2)
= 4x² - 8x + 2x - 4
= 4x² - 6x - 4
9). (3x + 2)(2x + 5)
= 3x(2x + 5) + 2(2x + 5)
= 6x² + 15x + 4x + 10
= 6x² + 19x + 10
10). (x² - 6)(x - 4)
= x²(x - 4) - 6(x - 4)
= x³ - 4x² - 6x + 24
11). (x² + 9)(x - 3)
= x²(x - 3) + 9(x - 3)
= x³ - 3x² + 9x - 27
12). (4x²- 4)(2x + 1)
= 4x²(2x + 1) - 4(2x + 1)
= 8x³ + 4x² - 8x - 4
Answer:
Step-by-step explanation:
There are four values 46, 51, 53, 59
we have to draw 2 sampler with replacement
sampler median samler median
46.46 46 53.46 49.5
46.51 48.5 53.51 52
45..53 49.5 53.53 53
46.59 52.5 53.59 56
51.46 48.5 59.46 52.5
51.51 51 59.51 55
51.53 52 59.53 56
51.59 55 59.59 59
sampling distribution of the median
median probability
46 1/16
48.5 2/16
49.5 2/16
52.5 2/16
51 1/16
52 2/16
55 2/16
53 1/16
56 2/16
59 1/16
It has to be 36 because it the same stick as the other stick that is telling 36
Step-by-step explanation:
2² * 3 * 5 = 4 * 3 * 5 = 60.
3² * 5² = 9 * 25 = 225.
Answer:
$0.45
Step-by-step explanation:
ratio is 2:4:3
total is 9
270 ÷ 9 = 30
smoll
60 × 0.25 = $15
med
120 × 0.30 = $36
Big
91.50 - 15 - 36 = 40.5
40.5 ÷ 90 = $0.45
