112
suplementry angle add to 180 so 180_68=112
D: 2/1
EXPLANATION:
Jacob has 8
Antonio has 4.
8/4 is the ratio
8/4 can be simplified to 2/1
Hope this helps!
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:
I believe D is the answer. (Triangles BPA and DPC are congruent.)
Angles BAD and ADC are not congruent.
Sides CD and DA are also not congruent
X ×2 + 3x -4>0
2x+3x-4>0
5x>4
x>4\5
x>0.8
I think that this right answer
