Whatever the answer is...whats the question
Answer:
81 samples
Step-by-step explanation:
According to the empirical rule :
Possible values of the sample mean is within 3 standard deviations of the population mean :
μ ± 3 sd(x) ; sd(x) = standard deviation of sampling distribution.
3 * sd(x) = 1
sd(x) = 1/3
Recall:
Standard deviation of sampling distribution, sd(x)
sd(x) = σ / sqrt(n)
1/3 = 3 / sqrt(n)
Square both sides
1/9 = 9/n
Cross multiply :
n * 1 = 9 * 9
n = 81
Answer:
B
Step-by-step explanation:
If you calculate the side of a square using pythagorean theorem, you would get a side length of sqrt37. Simple multiply this by 4
Answer:
C
Step-by-step explanation:
<em>B: 2X + 12 > 3</em>
2x > -9
x> -9/2
<em>C: 2X - 5 > 7</em>
2x > 12
x > 6
<em>D: 2x - 6 > 24</em>
2x > 30
x > 15
Hope this helps ^-^
Answer:
-2
Step-by-step explanation:
41 - 8m - 57 = 0
41- 8m = 57
-8m = 57-41
-8m = 16
m = -16/8
m = -2
