Answer:
Kind Note:
This question is incomplete. You need to provide the question in order to get the best answer on brainly. In this answer, I will tell you how many solutions are in this system of equations.
Step-by-step explanation:
This question involves the use of 'system of equations'.
3x - 2y = 44
- => (-3x + 3x) + (-7y - 2y) = (8 + 44)
- => -9y = 52
- => y = -52/9 (No further check required)
Since the y-intercept is valid, the system of equations has one solution.
Hence, this system of equations has one solution.

Answer:
the answer to the question is -16
<span>Defective rate can be expected
to keep an eye on a Poisson distribution. Mean is equal to 800(0.02) = 16,
Variance is 16, and so standard deviation is 4.
X = 800(0.04) = 32, Using normal approximation of the Poisson distribution Z1 =
(32-16)/4 = 4.
P(greater than 4%) = P(Z>4) = 1 – 0.999968 = 0.000032, which implies that
having such a defective rate is extremely unlikely.</span>
<span>If the defective rate in the
random sample is 4 percent then it is very likely that the assembly line
produces more than 2% defective rate now.</span>
