Step-by-step explanation:
Answer: 11 stickers each
Step-by-step explanation:
given data:
packs of stickers bought by mark = 12 ( 5 ) = 60 stickers
no of stickers left with mark = 27
= Total no of stickers – stickers remaining with mark
= 60 – 27
= 33 stickers
he gave his 3 friends equal number of stickers.
3x = 33
x = 11
number of stickers received by each friend is 11
Answer: A) 
B) H = 5.10
C) Yes
Step-by-step explanation: <u>Exponential</u> <u>Decay</u> <u>function</u> is a model that describes the reducing of an amount by a constant rate over time. Generally, it is written in the form: 
A) C is initial quantity, in this case, the initial concentration of DDT. To determine r, using the data given:



Using a natural logarithm property called <em>power rule:</em>



The decay function for concentration of DDT through the years is 
B) The value of H is calculated by 


Again, using power rule for logarithm:



H = 5.10
Constant H in the half-life formula is H=5.10
C) Using model
to determine concentration of DDT in 1995:

y(24) = 0.5
By 1995, the concentration of DDT is 0.5 ppm, so using this model is possible to reduce such amount and more of DDT.
12, 13, 15, 15, 16, 19,19,19,20,21,25 what is the median?

The median is the middle number.
The middle number is 19.
Median = 19.
