Answer:

Distance is a numerical measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria. The distance from a point A to a point B is sometimes denoted as |AB|.

Basile [38]

Answer:

The Z-score for that day's temperature is 2.41, and since Z > 2, this temperature is significantly high.

Step-by-step explanation:

Z-score:

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.

If $|Z| > 2$ , the measure X is significantly high(Z > 2) or significantly low(Z < -2).

The mean high temperature on a particular day in January is 31 degrees F and the standard deviation is 8.7 degrees.

This means that $\mu = 31, \sigma = 8.7$

One year, the temperature was 52 degrees F on that day.

This means that $X = 52$ .

What is the Z-score for that day's temperature?

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

$Z = \frac{52 - 31}{8.7}$

$Z = 2.41$

The Z-score for that day's temperature is 2.41, and since Z > 2, this temperature is significantly high.

Please please help i beg ill give brainlist

Answer:

$a_{15}=-268,435,456$

Step-by-step explanation:

First, find what factor each term is multiplied by to get to the next. To do this, divide the second term by the first, the third term by the second, etc

$4\div-1=-4\\-16\div4=-4\\64\div-16=-4$

The common factor is 4. Using that, you can now write the equation for the geometric sequence in the form of:

$a_n=a_1x^{n-1}$

It looks scarier than it is. aₙ is the nth term in the sequence, x is the factor, and n is the index in the sequence, that's all it is.

Plug in the information we have to get the equation for this sequence:

$a_n=(-1)(-4)^{n-1}$

Then, you can solve for the 15th term:

$a_{15}=(-1)(-4)^{15-1}\\a_{15}=(-1)(-4)^{14}\\a_{15}=(-1)(268,435,456)\\a_{15}=-268,435,456$

Basically, just raise the scale factor to the power of the term you want minus 1, then multiply that by the first number.

Sixteen boxes that are each 1 5/8 feet high are stacked. Find the height of the stack

kifflom [539]

Answer: 26
Explanation: 1 5/8 is equal to 13/8. 8/8 is equal to 1, and 8 plus 5 is 13. 13/8 is an improper fraction, but we will change that later. Since there are sixteen boxes, we must do 13/8 times 16, which is 208/8 if we do the math. 208 divided by 8 is 26.
