Answer:

Q1) D Q2) The final statement Q3) first statement Q4) (0,14) and (10,1)

Step-by-step explanation:

Q1) in this D has the most points therefore highest correlation

Q2) there is no correlation because the points cannot form a linear line

Q3) it does not touch all points but is extreamly close ans is therefore considered a correct linear correlation.

Q4) these points have the closest linear correlation

If the average price of four pairs of shoes is $50, and three of those pairs of shoes are priced at $35, $40 and $55, what is th

konstantin123 [22]

An average can be calculated by the quotient of the sum of all terms and the number of terms. In this instance, there are 4 pairs of shoes with three given values. Let's say x is the price of the fourth pair of shoes.

$\frac{35+40+55+x}{4} =50$

Clear the fraction by multiplying both sides of the equation by 4.

A study of long-distance phone calls made from General Electric Corporate Headquarters in Fairfield, Connecticut, revealed the l

Answer:

The probability that a call last between 4.2 and 4.9 minutes is 0.4599

Step-by-step explanation:

Let X be the length in minutes of a random phone call. X is a normal distribution with mean λ=4.2 and standard deviation σ=0.4. We want to know P(4.2 < X < 4.9). In order to make computations, we will use W, the standarization of X, given by the following formula

$W = \frac{X-\mu}{\sigma} = \frac{X-4.2}{0.4}$

We will use $\phi$ , the cummulative distribution function of W. The values of $\phi$ are well known and the can be found in the attached file

$P(4.2 < X < 4.9) = P(\frac{4.2-4.2}{0.4} < \frac{X-4.2}{0.4} < \frac{4.9-4.2}{0.4}) = P(0 < W < 1.75) = \\ \phi(1.75) - \phi(0) = 0.9599-0.5 = 0.4599$

We conclude that the probability that a call last between 4.2 and 4.9 minutes is 0.4599

MArishka [77]

Answer:

The rules for adding and subtracting signed decimals are almost the same as the rules for adding and subtracting integers. When dealing with decimals, you need to be especially aware that your decimal points are lined up so that you do not accidentally add or subtract in the wrong place.
