The annual gas bill for a town household are considered to be normally distributed with a mean of $ 1130 and a standard deviatio

Alexxx [7]

Answer:

The probability is $P(900 < X < 1100) = 0.358102$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = \$ 1130$

The standard deviation is $\sigma = \$ 150$

Generally the probability that the gas bill will be between $900 and $1100 is mathematically represented as

$P(900 < X < 1100) = P(\frac{900 - 1130 }{150 } < \frac{X - \mu}{\sigma } < \frac{1100 - 1130 }{150 } )$

=> $P(900 < X < 1100) = P(-1.533 < \frac{X - \mu}{\sigma } < -0.2 )$

Generally $\frac{X - \mu}{\sigma } = Z (The\ standardized \ value \ of \ X)$

So

$P(900 < X < 1100) = P(-1.533 < Z< -0.2 )$

$P(900 < X < 1100) = P( Z< -0.2 ) - P(Z < -1.533)$

From the z table

$P(Z < -0.2 ) = 0.42074$

and

$P(Z < -1.533) = 0.062638$

So

$P(900 < X < 1100) = 0.42074 - 0.062638$

=> $P(900 < X < 1100) = 0.358102$

Help me please help me

zlopas [31]

Answer:

m = -10.7

Step-by-step explanation:

m + 4.1 = -6.6

Subtract 4.1 from both sides:

m + 4.1 = -6.6

- 4.1 - 4.1

m = -10.7

Final answer: m = -10.7

Hope this helps!
