Answer:
its either B or D
Step-by-step explanation:
7<-2× +3
2×=4
7< -4+3
-4+3=-7
7<-7
which is greater negative or positive?
sicne it is on the -7 then that is the answer but i dont know which is greater of negative or positive if you think its is positive then it might be C or A
I think the correct answer from the choices listed above is the last option.The expression x^2 + 16 is a prime expression which cannot be further simplified over the real numbers<span>. But when considering the complex numbers, the factor would be:
</span><span>(x + 4i)(x - 4i)</span>
Answer:
492 0/10
Step-by-step explanation:
We have that the perimeter is 4 times the length of the side, now we know that this side "l" is given by:
l = 4 in * 24 + 23 * 5 ft
l = 96 in + 115 ft
Now, we pass the inches to pes, knowing that 1 foot equals 12 inches, so
96 in * 1 ft / 12 in = 8 ft
therefore replacing it remains:
l = 8 ft + 115 ft
l = 123 ft
now the perimeter:
p = 123 * 4
p = 492
to change to a mixed number:
4920/10 = 492 0/10
Answer:
Step-by-step explanation:
Since the the production of the polymer fiber follows a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = measured diameter values.
µ = mean diameter
σ = standard deviation
From the information given,
µ = 30 μm
σ = 20 μm
a) The probability of a measured value greater than 80 μm is expressed as
P(x > 80) = 1 - P(x ≤ 80)
For x = 80,
z = (80 - 30)/20 = 2.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.994
P(x > 80) = 1 - 0.994 = 0.006
b) the probability of a measured value between 60 and 75 μm is expressed as
P(60 ≤ x ≤ 75)
For x = 60,
z = (60 - 30)/20 = 1.5
The probability corresponding to the z score is 0.933
For x = 75,
z = (75 - 30)/20 = 2.25
The probability corresponding to the z score is 0.988
Therefore,
P(60 ≤ x ≤ 75) = 0.988 - 0.933 = 0.055
