An entrepreneur estimates that the total profit (profit = total revenue minus total cost) from his proposed company will be give

SOVA2 [1]

No profit means P(x)=0: x³-4x²+3x-12=0
factor by regrouping: x²(x-4)+3(x-4)=0
take out (x-4): (x-4)(x²+3)=0
x=4 or x²=-3
x² is not a negative number, so x=4 is the only answer.

Shannon is choosing between two different saving account for her college fund the first account compounds interest semiannually

Kitty [74]

100×(1+0.11÷2)^(2×5)
=170.81

100×e^(0.108×5)
=171.60
So she should choose the account which pays the interest continuously

An ordinance requiring that a smoke detector be installed in all previously constructed houses has been in effect in a particula

bonufazy [111]

Answer:

a. P=0.01222

b. P=0.98778

c. The probability of rejecting the claim is now P=0.00298.

Step-by-step explanation:

In this case, we evaluate the sampling distribution for a population proportion π=0.8 with a sample size of 25.

We need to calculate the probability of getting a sample mean below 15, which means p=15/25=0.6.

The standard deviation of the sampling distribution is:

$\sigma_M=\sqrt{\frac{\pi(1-\pi)}{N}} =\sqrt{\frac{0.8\cdot0.2}{25}} =\sqrt{\frac{0.16}{25} } =0.08$

The z value por p=0.6 is

$z=\frac{p-\pi+0.5/N}{\sigma} =\frac{0.6-0.8+0.5/25}{0.08}= \frac{-0.18}{0.08} =-2.25$

The probability of having a sample mean less than 15 is

$P(\bar X$

The probaiblity of not rejecting the claim is 1-0.01222=0.98778

If the value 15 is replaced by 14, we have a new value of p=14/25=0.56.

There will be less chances of rejecting the hypothesis.

$z=\frac{p-\pi+0.5/N}{\sigma} =\frac{0.56-0.8+0.5/25}{0.08}= \frac{-0.22}{0.08} =-2.75$

$P(\bar X$
