What is the mean of exam scores?

The mean of exam scores is the sum of the scores divided by the number of exams taken, more like an average of all scores

Initially, average score on 4 exams is 82

average=total score/number of exams

average score on 4 exams=82

total score =unknown=assume it is

number of exams=4

82=x/4

x=4*82

x=328

In order to have an overall average score of 85, we would sum the total score of 4 exams and the fifth exam and divide by 5 exams

85=(328+y)/5

85*5=328+y

425=328+y

y=425-328

y=97

The function f(x) = 7(1.32)x models the number, in billions, of the DNA sequences in a database x years since 2010. What does th

NikAS [45]

Answer:

The correct option is (A).

Step-by-step explanation:

The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:

$f(x)=7\cdot (1.32) x$

The general growth function can be represented as:

$y=a\cdot (1+r)^{t}$

Here,

y = final value

a = initial value

r = growth rate

t = time

Com-paring the two functions we get:

$1+r=1.32\\r=1.32-1\\r=0.32$

This implies that the annual increase rate in number, in billions, of the DNA sequences is 32%.

Thus, the correct option is (A).
