Input m = -4 n = 2 and p = 1.5 into the expression above
7m + 2n - 8p/n
= 7(-4) + 2(2) - 8(1.5)/2
= -28 + 4 - 6
= -30
Answer:
33/95 or 34.74 %
Step-by-step explanation:
total # of kids = 20
chance first student would be a girl: 3/5
chance second student would be a girl: 11/19
3/5 × 11/19 = 33/95
Answer:
9
Step-by-step explanation:
The answer is the mean. In statistics, the standard deviation is a measure that is used to compute the amount of variation or distribution of a set of data values. In other words, standard deviation (also variance) are measures of the spread of the data around the mean. They summarize how near each observed data value is to the mean value. A low standard deviation indicates that the data points tend to be close to the mean (otherwise known as the expected value) of the set, while a high standard deviation indicates that the data points are vast over a wider range of values.
Using exponential function concepts, it is found that the correct sentence is given by:
The temperature difference is reduced by a factor of 
every 9.7 seconds.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate every n instants of time, as a decimal.
In this problem, the function is given by:
The decay rate is given by:
Hence, the sentence is:
The temperature difference is reduced by a factor of every 9.7 seconds.
