Answer:
132.48
On your calculator do 0.69x192, as that removes 0.31 of 192, or 31%.
Answer:
-81r - 6
Step-by-step explanation:
8(-10r - 1) - r + 2
use the distributive property
-80r - 8 - r + 2
combine like terms
<em><u>-81r - 6</u></em>
plz mark as brianliest if correct!!!
If you count the bottom rung, the answer is 4 hours.
If the rope is 10 feet long, and each rung is 1 ft apart, there must be 9 spaces between the rungs on the ladder. This can be shown with a number line, although it is not necessary to answer the question.
One foot is 12 inches, so it would take 2 hours for one rung to be covered.
However, since we have already said the bottom rung is touching the surface of the water, it shouldn't need any inches.
So if we exclude the bottom rung, there are two rungs left. 2 x 2 = 4.

Answer:
Interpreting the results:
a) At least 99.3% of the data lies between 12 standard deviations of the mean
b) The data lies between points 0 and 168
Step-by-step explanation:
The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 5 points. Apply chebychev's theorem to the data using k= 12 interpret the results
Chebychev's theorem states that:
At least 1 - 1/k² data lies between k standard deviation of the mean
μ ± kσ
Where k is a positive number greater than 1
From the question above
μ = Mean = 84 points
σ = Standard deviation = 5 points
Hence: k = 12
We have:
1 - 1/12²
= 1 - 1/144
= 144 - 1/144
= 143/144
= 0.9930555556
Approximately = 99.3%
Interpreting these results means that At least 99.3% of the data lies between 12 standard deviations of the mean
Hence,
μ - kσ
84 - 12 × 7
= 84 - 84
= 0
μ + kσ
84 + 12 × 7
= 84 + 84
= 168
Hence, the data lies between points 0 and 168
