Answer:

1/9

Step-by-step explanation:

The answer is 1/9 because we already know the only even number on the spinner is 8. We have a 1/3 chance on landing on 8. Then it says we have to land on 7. There is also a 1/3 chance for landing on 7. So from this information, we do (1/3)*(1/3)=1/9

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).

Round your answer to the nearest hundredth. -1.7f - 26 = 34

Softa [21]

F=-35.29
Add 26 to both sides. -1.7=34+26
Simply 34+26=60 -1.7f=60
Divide both sides by -1.7 f=-60/1.7
Simply-60/1.7 to get -35.294118 then round to nearest hundredth to get F=-35.29
Hope That helps!!!
