Julio says "If you subtract 13 from my number and multiply the difference by -6, the result is -144." What is Julio's number?
PLEASEEE HELPPP!!!!!!!​

Answer:

First, find the value of x:

\(h(5-x)=h(9)\\5-x=9\\-x=9-5\\-x=4\\x=-4\)

Substitute the x-value in to the function \(x^{2}+x+1\) and solve:

\((-4)^{2}+(-4)+1=16-4+1=12+1=13\)

Therefore, the value of h(9) = 13.

Hope this is correct O-o

Answer:

A

Step-by-step explanation:

Since we need to find the value of h(9), we can substitute the (5-x) part from the original equation with 9 to get the value of x, which is 5-x = 9, x = -4. With that, we can go ahead and plug the x into the right side of the equation to get (-4)^2 + (-4) + 1, which equals 16 - 4 + 1, which equals 13.

A normal distribution of a random variable cannot be described (D) by a graph that is centered on the mean.

A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.

Since all three of these variables are equal in a normal distribution, they serve as the center of the graph and can either be zero or not.

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme.

The distribution's mean is another name for the center of the range.

Therefore, a normal distribution of a random variable cannot be described (D) by a graph that is centered on the mean.

Answer:

V would equal -7.1.

Step-by-step explanation:

It appears you have set the decimal points as commas. Let's remove that and replace it with decimal points. (AkA ".")

First, we move every term with "V" in this problem to the left.

-9.45 - 3.3v = 13.98

Next, we add -9.45 to 13.98 which equals 23.43.

We then make 3.3v negative.

-3.3v = 23.43

We then divide 23.43 and 3.3v by 3.3.

We cancel out 3.3v to leave 23.43/3.3.

We can now divide 23.43 by 3.3 to get -7.1.

V = -7.1

Answer:

V would equal -7.1.

An effective sampling method is not cast doubt on the usefulness of the sample

The effective sample is a calculation of the approximate sample size needed to obtain the same degree of accuracy as a simple random sample. It is denoted mathematically by the formula n/D, where n represents the sample size and D denotes the design effect. It is employed as a means of condensing the volume of data.

Effective sample size calculations are mostly used for qualitative analyses of the sample size. The sample size calculates the total number of measurements or observations made during an experiment or survey. The effective sample size—rather than the actual sample size—is utilized in this assessment since it is thought that a sample size of 30 is necessary for an analysis to be valid.

Step-by-step explanation:

You subtract 373,558 and 5,377

373,558-5,377 and you get 368,181

Answer:

Think of the equation as an equation for a line  y = m x + b  where in this case  C = 5 9 ( F − 32 )  or  C = 5 9 F − 5 9 ( 32 )  You can see the slope of the graph is  5 9 , which means that for an increase of 1 degree Fahrenheit, the increase is  5 9  of 1 degree Celsius.  C = 5 9 ( F )  C = 5 9 ( 1 ) = 5 9  Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of  9 5  degrees Fahrenheit.  C = 5 9 ( F )  1 = 5 9 ( F )  ( F ) = 9 5  Since  9 5  = 1.8, statement II is true.  The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of  5 9  degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:  C = 5 9 ( F )  C = 5 9 ( 5 9 )  C = 25 81 ( which is ≠ 1 )  An increase of  5 9  degree Fahrenheit leads to an increase of  25 81 , not 1 degree, Celsius, and so Statement III is not true.  The final answer is D.

The correct statement regarding whether Maple Street and Elm Street are parallel lines is given as follows:

Yes, because angles 1 and 2 are supplementary.

Parallel lines are two lines that do not intersect, or technically, intersect only at infinity.

In this problem, we have that angles 1 and 2 are supplementary angles, hence:

m<1 + m<2 = 180º

As the sum of the measures of supplementary angles is of 180º.

Then these two angles are classified as consecutive interior angles, meaning that Maple Street and Elm Street are parallel lines cut by the transversal River Drive.

Thus the second option is the correct option.

Answer:

The scale factor is 4/3 or 1.333...

Step-by-step explanation:

We're trying to find how can A go to B

Example: 16 --> 12

16 Divided by 12 = 4/3

\(\frac{16}{1}\)÷\(\frac{12}{1} = \frac{16}{1} * \frac{1}{12} = \frac{16}{12} = \frac{4}{3}\)

This will work with other numbers too.

The P-value for the given test statistic (z = 1.95) in a two-tailed test is 0.0512. With a significance level of 0.05, we fail to reject the null hypothesis.

In hypothesis testing, the P-value is the probability of obtaining a test statistic as extreme as or more extreme than the observed test statistic, assuming the null hypothesis is true.

In this case, we have a two-tailed test, meaning we are interested in the possibility of the test statistic being either positive or negative. Since the z-value is positive, we use the upper tail of the standard normal distribution to calculate the P-value. Using a standard normal distribution table or calculator, we find that the area to the right of z = 1.95 is 0.0256.

However, since this is a two-tailed test, we need to account for the possibility of a negative test statistic as well. Therefore, we double the area of the upper tail (0.0256 x 2 = 0.0512) to get the P-value.

Since the P-value (0.0512) is greater than the significance level of 0.05, we fail to reject the null hypothesis. This means that we do not have enough evidence to support the alternative hypothesis and we conclude that the null hypothesis is plausible. In other words, there is no significant difference between the observed sample and the population parameter, assuming the null hypothesis is true.

The interquartile range is least affected by an outlying value in the data set of the range, interquartile range, and variance is True.

Max to min value is the range. Range can substantially change if there are any outliers.

Since the threshold values for Q3 and Q1 are not outliers, the IQR won't change.

Outliers cause variance to be misinterpreted since they vastly increase variance.

Interquartile range:

You may determine the spread of the midpoint of your distribution using the interquartile range.

The interquartile range contains half of the values for any distribution that is ordered from low to high. The first 25% of values are found in the first quartile (Q1), while the last 25% are found in the fourth quartile (Q4).

The third quartile (Q3) less the first quartile (Q1) is the interquartile range (Q1). This provides us with the data set's middle half's range.

The interquartile range is calculated using only 2 values, much like the range. The IQR, however, is less impacted by outliers because the two values are more likely to be average scores because they are drawn from the middle of the data set.

The IQR provides a reliable indicator of variability for both skewed and normal distributions.

Step-by-step explanation:

According to the empirical rule, approximately 95% of the data falls within two standard deviations of the mean. Therefore, the approximate percentage of daily phone calls numbering between 35 and 75 is 95%.

We have been given that the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 55 and a standard deviation of 10.

We are asked to find out the approximate percentage of daily phone calls numbering between 35 and 75 using the empirical rule.

The empirical rule is used to describe how many of the observations fall within a certain distance of the mean in a normal distribution of data.

The empirical rule states that approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations of the mean, and 99.7% falls within three standard deviations of the mean.

To use the empirical rule, we first need to find the z-scores for the values of 35 and 75. We can use the formula

z = (x - μ) / σ,

where x is the value we want to find the z-score for, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

For x = 35, we have

z = (35 - 55) / 10 = -2, and

for x = 75, we have

z = (75 - 55) / 10 = 2.

So, the values of 35 and 75 are 2 standard deviations away from the mean. According to the empirical rule, approximately 95% of the data falls within two standard deviations of the mean.

Therefore, the approximate percentage of daily phone calls numbering between 35 and 75 is 95%.

Given :

given the y- intercept and x- intercept . y intercept ( 0, -2) and x intercept is (-3, 0)

We need to frame the equation of the line y=mx+b

where m is the slope and b is the y intercept

y intercept is (0,-2) so the value of b=-2

Now we find slope using two points (0,-2) and (-3,0)

Apply slope formula

\(slope m =\frac{y_2-y_1}{x_2-x_1} =\frac{0+2}{-3+0} =-\frac{2}{3}\)

We got the slope m and y intercept b =-2

m=n and C=D, as CD is an nxn matrix and In and Im have dimensions nxn and mxm, respectively.

To prove that m=n, let us consider the dimensions of the matrices involved. The matrix product CD has dimensions nxm times mxn, which gives an nxn matrix. On the other hand, the identity matrices In and Im have dimensions nxn and mxm, respectively. Therefore, for the products CA and AD to be well-defined, we must have m=n.

Now, let us show that C=D. We have:

CA = In (given)

AD = Im (given)

Multiplying both sides of the first equation by D on the right and both sides of the second equation by C on the left, we get:

CAD = D (from CA=In)

CAD = C (from AD=Im)
