8.54. The last number is low so it can not round up to 5

See if the number in the thousandths place is higher or lower than 5 .If its is lower than 5 then get rid of it. If it is higher than 5 then increase the #in the hundredth place by one and drop the thousandths place. 8.544 = 8.54 we rounded

A student recorded her scores on weekly math
alina1380 [7]

Answer:

mean: 7.62

median: 8

mode: 9

Step-by-step explanation:

first you have to put the data set in order:

6,6,6,6,7,7,8,8,9,9,9,9,9

the mode is the most often repeated number in a data set so the mode in this data set would be 9. The median is the middle number in the data set. The middle number in this data set is 8. Lastly, the mean in a data set is all of the numbers in the data set added together and then divided by how many numbers are in the set. The equation for this data set would be 99/13= 7.62

hope this helps!!

The amount of​ carbon-14 present in a paint after t years is given by y equals y Subscript o Baseline e Superscript negative 0.0
Anni [7]

Answer:

16,383.33 years ( approx )

Step-by-step explanation:

Given equation that shows the amount of carbon-14 after t years,

y = y_0 e^{-0.00012t}

Where,

y_0 = initial amount,

∵ 14% of y_0 = \frac{14}{100}y_0 = \frac{7}{50}y_0

\frac{7}{50}y_0= y_0 e^{-0.00012t}

\frac{7}{50}=e^{-0.00012t}

Taking ln both sides,

\ln(\frac{7}{50})=-0.00012t

-1.966=-0.00012t

\implies t =\frac{-1.966}{-0.00012}=16383.33

Hence, the painting would be 16383.33 years old ( approx )
