Step-by-step explanation:
PQ*PQ=PQ²=(5x+16)²=25x²+160x+256
Answer:
N = 17
Step-by-step explanation:
In a parallelogram the opposite angles are congruent, hence
4n - 2 = 2n + 32 ( subtract 2n from both sides )
2n - 2 = 32 ( add 2 to both sides )
2n = 34 ( divide both sides by 2 )
n = 17
(-5/8)(X) = -0.4
(-5/8)(X) = -4/10
X = (-4/10) / (-5/8)
X = (4/10) / (5/8)
X = (4/10)(8/5)
X = (2/5)(8/5)
X = 16/25
Letter D
Answer:
81.85%
Step-by-step explanation:
We have the following information:
mean = m = 52000
standard deviation = sd = 12000
a = 40000
b = 76000
we need to find the probability between a and b, that is:
P (a <x <b) = P (40,000 <x <76000)
P [(40000 - m) / sd <(x - m) / sd <(76000 - m) / sd]
replacing
P [(40000 - 52000) / 12000 <z <(76000 - 52000) / 12000]
P (-1 <z <2)
P (z <= -1) - P (z <= 2)
We look for this value of z, in the attached table:
0.9772 - 0.1587
P = 0.8185
In other words, the probability is 81.85%
