An airline records data on several variables for each of its flights, model of plane, amount of fuel used, time in flight,

Troyanec [42]

Answer:

The correct option is;

2 categorical, 3 quantitative (1 discrete, 2 continuous)

Step-by-step explanation:

A categorical variable which is otherwise known as a nominal variable is one which can be qualified as belonging to one class or category of objects or the other, depending on its attributes, and not based on order of the classes.

Therefore;

1) The model of the plane, and 2) whether the flight arrived on time, are categorical variable

A quantitative variable is a variable that indicates measurement and therefore, indicates the numerical magnitude of a measurement.

Therefore;

1) Amount of fuel used, 2) Time in flight, 3) The number of passengers are quantitative variables

Quantitative variables can be either discrete or continuous

A discrete quantitative variable is one that has a finite number of possible values or which may have an infinite but countable number of values

Therefore;

1) The number of passengers which is countable and exact is a discrete quantitative variable

A continuous variable is one whose exact or accurate value range is infinite or a variable with a limitless value set such as the range of values between two real numbers

Therefore;

1) Amount of fuel used and 2) Time of flight are continuous quantitative variables.

When you translate, (x, y+6) will move

Darya [45]

Answer:

(x, y+6) will vertically move 6 units up.

Step-by-step explanation:

If we move vertically 6 units up, 6 is added to the y-coordinate.

so

(x, y+6) will vertically move 6 units up.

For example, let suppose the point P(-2, 3). When we apply a translation of (x, y+6) to the point P(-2, 3), the coordinates of point P after the translation will be:

(x, y) → (x, y+6)

P(-2, 3) → P(-2, 9) ∵ P(-2, 3+6)

Therefore, (x, y+6) will vertically move 6 units up.

Certain three-cylinder combination lock has 70 numbers on it. to open it, you turn to a number on the first cylinder, then to

lord [1]

The lock has 3 different cylinders that can take up to 70 possible numbers. The possible combination of each cylinder would be 70!
The order of cylinder would be important because the password on 1st cylinder can't be used on cylinder 2. The calculation would be:

possible lock combination= 1st cylinder possible combination* 2nd cylinder possible combination * 3rd cylinder possible combination
possible lock combination= 70!*70!*70!

A researcher tests the braking distances of several cars. The braking distance from 60 miles per hour to a complete stop on dry

ZanzabumX [31]

Answer:

The longest braking distance one of these cars could have and still be in the bottom 1% is of 116.94 feet.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

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

$Z = \frac{X - \mu}{\sigma}$

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 p-value, we get the probability that the value of the measure is greater than X.

The braking distances of a sample of cars are normally distributed, with a mean of 129 feet and a standard deviation of 5.18 feet.

This means that $\mu = 129, \sigma = 5.18$

What is the longest braking distance one of these cars could have and still be in the bottom 1%?

This is the 1st percentile, which is X when Z has a pvalue of 0.01, so X when Z = -2.327.

$Z = \frac{X - \mu}{\sigma}$

$-2.327 = \frac{X - 129}{5.18}$

$X - 129 = -2.327*5.18$

$X = 116.94$

The longest braking distance one of these cars could have and still be in the bottom 1% is of 116.94 feet.
