Using the normal distribution and the central limit theorem, it is found the power of the test is of 0.

In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The power of a test is the probability of rejecting a true null hypothesis, which in this problem is concluding that there is significant evidence that the mean speed is above 95 m/s when in fact it isn't, which is the probability of finding a sample mean above 102.2 m.

For this problem, the parameters are:

The probability is 1 subtracted by the p-value of Z when X = 102.2, then:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{102.2 - 95}{\frac{4}{\sqrt{8}}}\)

\(Z = 5.1\)

\(Z = 5.1\) has a p-value of 1.

1 - 1 = 0

The power of the test is of 0.

Answer:

The company had 32,000 employees a year ago.

Step-by-step explanation:

Last year, the company had x employees.

Today the company has 35% more employees than it did a year ago.

So now it has 100% + 35% = 135% of last year, that is, 1.35x

There are currently 43,200 employees

So

\(1.35x = 43200\)

How many employees did the company have a year ago?

We have to solve the equation for x. So

\(x = \frac{43200}{1.35} = 32000\)

Using the properties of logarithms, we can simplify the expression:

4 log3x + 6 log3y - 7 log3z = log3x^4 + log3y^6 - log3z^7

Now, we can use another property of logarithms, which states that:

loga (mn) = loga m + loga n

Using this property, we can combine the logarithms with addition or subtraction:

log3x^4 + log3y^6 - log3z^7 = log3(x^4 * y^6 / z^7)

Therefore, the simplified form of 4 log3x + 6 log3y - 7 log3z is log3(x^4 * y^6 / z^7).

Answer: The initial amount of syrup is (total volume of container + 2/5) * 5/5.

Since we don't know the total volume of the container we can not give you the value of S in its simplest form, we only have a relation between the initial amount of syrup and the total volume of the container. call the initial amount of syrup S.

We know that the container was 5/9 filled with syrup, so the initial amount of syrup is 5/9 * the total volume of the container.

We also know that Nick had the same amount of water and syrup left.

And he used 2/5 liter more water than the syrup.

So, if the amount of syrup used is s, and the amount of water used is w, we can set up the following equation:

s + w = S

w = s + 2/5

We also know that the container was filled with water, so the amount of water used is equal to the total volume of the container.

So we can set up another equation:

w = total volume of container

Now we have 2 equations with 2 unknowns, we can substitute the second equation into the first equation.

s + (s + 2/5) = S

Combining like terms and solving for s:

2s + 2/5 = S

2s = 5/5S - 2/5

s = 5/5S - 2/5

Now we can substitute this value of s back into the equation w = s + 2/5 and solve for the initial amount of syrup S.

w = s + 2/5

w = (5/5S - 2/5) + 2/5

w = total volume of container

5/5S - 2/5 + 2/5 = total volume of container

5/5S = total volume of container + 2/5

S = (total volume of container + 2/5) * 5/5

Therefore, the initial amount of syrup is (total volume of container + 2/5) * 5/5.

Answer:

22% is greater.

Step-by-step explanation:

0.023 x 100 = 2.3

Answer:

22%

Step-by-step explanation:

22% is greater than 0.023 because 22% is equal to 0.22.

Answer:

a) 0.80

b) 0.72

c) 0.02

Step-by-step explanation:

It is assumed that

X = Bit transmitted

Y = Bit received

\(X^{0}\) = Transmissted bit is 0

\(X^{1}\) = Transmissted bit is 1

\(Y^{0}\) = Received bit is 0

\(Y^{1}\) = Received bit is 1

As per the given condition

P [ \(Y^{0}\) | \(X^{0}\) ] = 90%

P [ \(Y^{0}\) | \(X^{1}\) ] = 100% - 90% = 10%

P [ \(Y^{1}\) | \(X^{1}\) ] = 74%

P [ \(Y^{0}\) | \(X^{0}\) ] = 100% - 74% = 26%

P [ Tramitted bits are 0 ] = 80%

Now calculate each situation

a)

As all the transmitted bits are o has possibilit of 80% then

P [ X = 0 ] = P [ \(X^{0}\) ] = 80% = 0.80

b)

P [ X = 0, Y = 0 ] = P [ \(X^{0}\) , \(Y^{0}\) ] = P [ \(Y^{0}\) | \(X^{0}\) ] x P [ \(X^{0}\) ]  = 90% x 80% = 72% = 0.72

c)

P [ X = 1, Y = 0 ] = P [ \(X^{1}\) , \(Y^{0}\) ] = P [ \(Y^{0}\) | \(X^{1}\) ] x P [ \(X^{1}\) ]  = 10% x ( 100% - 80% ) = 10% x 20% = 2% = 0.02

Answer:

The length of o is 24 centimeters

Step-by-step explanation:

In Δ OPQ

∵ Side p is opposite to ∠P

∵ Side q is opposite to ∠Q

∵ Side o is opposite to ∠O

→ To find side o we must use the cosine rule

∴ o = \(\sqrt{p^{2}+q^{2}-2(p)(q).cos(O) }\)

∵ p = 38 cm

∵ q = 29 cm

∵ m∠O = 39°

→ Substitute them in the rule to find o

∴ o = \(\sqrt{(38)^{2}+(29)^{2}-2(38)(29).cos(39)}\)

∴ o = 23.92008154

→ Round it to the nearest centimeter (whole number)

∴ o = 24 centimeters

∴ The length of o is 24 centimeters
