Answer:

B. 8 1/5

Step-by-step explanation:

To find the value of n, we need to isolate it

13+5n = 54  Subtract both sides by 13

5n = 41         Divide both sides by 5

n =  8 1/5

wel

Answer:

The most absolute error is 12

Step-by-step explanation:

The formula for absolute error is given by the following relation;

Absolute error, Δx = Value measured, x₀ - Exact (actual) value, x

Δx = x₀ - x

Since the actual count is between 77 and 89, the maximum absolute error will be where the actual value = 77 and the measured value = 89 and vice versa, giving an absolute error of 89 -77 = 12.

The most absolute error = 12.

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

State the dimensions of the matrix. identify the indicated element
blondinia [14]

The dimensions of the matrix are 3 by 3 i.e. 3 x 3, and the indicated element a₂₃ is -7

<h3>The dimension of the matrix?</h3>

From the figure in the question, we have the following highlights:

  • The matrix has 3 rows
  • The matrix has 3 columns

The dimensions of a matrix are represented by: Row by column

Hence, the dimensions of the matrix are 3 by 3

<h3>The indicated element</h3>

This is given as:

a₂₃

This means that the element is located at the second row and the third column.

The element at this position is -7

Hence, the indicated element is -7

What does 8 + 1/3 3 = <br> show your work please
irakobra [83]

Answer:

It's either 9 or 0.24 repeated

Step-by-step explanation:

I wasn't sure which of those would be the answer for your equation, since your equation didn't make sense.

8 + 1/3 (3) = 9

8 + 1/3 (3/1) = 9

8 + 3/3 = 9

8 + 1 = 9

---------------------- This will be the second equation:

8 + 1/33 = 0.24 repeated

8/1 + 1/33 = 0.24 repeated

8/33= 0.24 repeated

Hope this helped !!
