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.
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
and standard deviation
, the z-score of a measure X is given by:

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
, 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 
One year, the temperature was 52 degrees F on that day.
This means that
.
What is the Z-score for that day's temperature?



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

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 !!
