An train station has determined that the relationship between the number of passengers on a train and the total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation y=103+30x. Predict the weight of luggage for a flight with 86 passengers.

Answers

Answer 1

Answer:

Answer:

2683

Step-by-step explanation:

Using the linear regression equation that predict the relationship between the weight of the luggage and the total number of passenger y = 103 + 30x, we can plug in the number of passenger x = 86 to predict the weight of the luggage on a flight:

y = 103 + 30*86 = 2683

Scores on a college entrance exam are normally distributed with a mean of 550 and a standard deviation of 100. Find the value that represents the 90th percentile of scores. Answer with a whole number.

Answers

Answer:

The value that represents the 90th percentile of scores is 678.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = (X - \mu)/(\sigma)$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 550, \sigma = 100$

Find the value that represents the 90th percentile of scores.

This is the value of X when Z has a pvalue of 0.9. So X when Z = 1.28.

$Z = (X - \mu)/(\sigma)$

$1.28 = (X - 550)/(100)$

$X - 550 = 100*1.28$

$X = 678$

The value that represents the 90th percentile of scores is 678.

The function f(x)=101+25x2 is represented as a power series f(x)=∑n=0[infinity]cnxn. Find the first few coefficients in the power series. Some of the other problems only ask for the nonzero coefficients, but in this problem you are supposed to include those coefficents that are 0. Also, this problem is only asking for the coefficients of the power series. It does not want you to include the x's or the powers of x.

Answers

Answer:

$\large a_0=101,\;a_1=0,\;a_2=25,\;a_n=0\;for\;n>2$

Step-by-step explanation:

Since f(x) is a polynomial, it is a power series by itself with

$\large a_0=101,\;a_1=0,\;a_2=25,\;a_n=0\;for\;n>2$

On the other hand, the representation of a function as a power series around a given point is unique. This means that these are the only possible coefficients of f as a power series around 0.

The value of y is 225 when x is 50 from the given graph.

What is Coordinate System?

Arrangement of reference lines or curves used to identify the location of points in space is called as Coordinate system.

We need to find the value of y when x is fifty.

In the given graph we have to draw a perpendicular line at x =50.

Now we have to check the point where the perpendicular line touches the graph curve.

Take the corresponding value of y.

When x is 50 the value of y is nearly to 225.

Hence, the value of y is 225 when x is 50.
