PLS HELP!!

An attorney charges $250 for an initial meeting and $150 an hour. How many hours can Pablo afford if he has $500? Which equation

zhuklara [117]

Answer:

1 Hour

250 + 150h = 500

Step-by-step explanation:

So, the fee for the meeting is 250. The hourly fee is 150. Let h equal the number of hours.

250 + 150h

If pablo has 500, then we cannot exceed that amount. So, our equation becomes

250 + 150h = 500

Subtract 250 from both sides

150h = 250

And divide by 50 on both sides. You get x = about 1.67. Since this is a question about time and money, you would round down to 1.

An outlier always affects the mean. True False

Ipatiy [6.2K]

Yes. If you have very high or very low outliers in your data set, it is generally preferred to use the median - the mid-point when all data points are arranged from least to greatest.

A good example for when to avoid the mean and prefer the median is salary. The mean is less good here as there are a few very high salaries which skew the distribution to the right. This drags the mean higher to the point where it is disproportionately affected by the few higher salaries. In this case, the median would only be slightly affected by the few high salaries and is a better representation of the whole of the data. 

In general, if the distribution is not normal, the mean is less appropriate than the median.

When she adds 2 to both sides, the equation 4x = 3x results. Which solution will best illustrate what happens to x ?

kotykmax [81]

The solution will illustrate that the equation has one solution at x=0.

Given that adds 2 to both sides, the equation 4x = 3x results.

An algebraic equation may be described as a mathematical declaration wherein expressions are set the same as every other.

The equation is 4x=3x.

As given that add 2 on both sides, we get

4x+2=3x+2

Now, we will subtract 3x from both sides, we get

4x+2-3x=3x+2-3x

x+2=2

Further, we will subtract 2 from both sides, we get

x+2-2=2-2

x=0

Hence, When adds 2 to both sides, the equation 4x = 3x results that the equation has one solution x=0.

The U.S. Department of Agriculture claims that the mean consumption of coffee by a person in the United States is 24.2 gallons p

Dmitry_Shevchenko [17]

Answer:

The decision rule is

Reject the null hypothesis

The conclusion is

There is sufficient evidence to reject the claim

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 24.2 \ gallons \ per \ year$

The sample size is n = 101

The sample mean is $\= x = 23.5 \ gallons\ per\ year$

The standard deviation is $\sigma = 3.2 \ gallons$

The null hypothesis is $H_o : \mu = 24.2$

The alternative hypothesis is $H_a : \mu \ne 24.2$

Generally the test statistics is mathematically represented as

$z = \frac{ \= x - \mu }{ \frac{\sigma }{ \sqrt{n} } }$

=> $z = \frac{ 23.5 - 24.2 }{ \frac{ 3.2}{ \sqrt{ 101} } }$

=> $z = -2.198$

From the z table the area under the normal curve to the left corresponding to -2.198 is

$P(Z < -2.198 ) = 0.013975$

Gnerally the p-value is mathematically represented as

$p-value = 0.013975 * 2$

=> $p-value = 0.02795$

From the value obtained we have that $p-value \ < \ \alpha$ hence

The decision rule is

Reject the null hypothesis

The conclusion is

There is sufficient evidence to reject the claim

Using the Rejection Regions for a z-test method

Generally from the z table the critical value of $\frac{\alpha }{2}$ is

$z_{critical} = \pm 1.96$

Not we are using $\frac{\alpha }{2}$ because it is a two - tailed test

Now comparing the critical value and the test statistics we see that the

region covered by the test statistics (i.e $2.198 < z < -2.198$ ) is greater than the region covered by the critical value (i.e $1.96 < z < -1.96$ )

Hence

The decision rule is

Reject the null hypothesis

The conclusion is

There is sufficient evidence to reject the claim
