f(x)=2,459(0.92)^t
Using the information given above, complete the following statements. The percent change is %. The percent change represents .
f(x)=2,459(0.92)^t
Given equation is an exponential function and in the form of f(x) = a(1-r)^x
Where 'a' is the initial population
'r' is the decay rate
'x' is the time
f(x) = a(1-r)^x
Given function is f(x)=2,459(0.92)^t
1 - r = 0.92
r = 1 - 0.92
r = 0.08
r= 0.08 %
Percentage change = 0.08%
Percentage change represents the decay rate.

Each of them will have 5 berries
Answer:
4
Step-by-step explanation:
3y - 4 + 2y
0 = 3y - 4 + 2y
4 + 0 = 3y - 2y
4 = y
y = 4
is this what you want ?
answer to this one is b
Step-by-step explanation:
Answer:
Strength and direction of the relationship.
Step-by-step explanation:
Given that A study finds a correlation coefficient of r = .32. This number gives you information about which of the following?
Group of answer choices Type of relationship and importance Statistical validity and external validity Statistical significance and effect size Strength and direction of the relationship.
We know that correlation coefficient represented by r is a measure of association between two variables. r can lie between -1 and 1. While negative correlation suggests inverse relationship positive a positive association.
0 correlation means the two variables are independent.
If nearer to 0, it represents weak correlation and nearer to 1 than 0 represents strong correlation.
Here r =0.32 a weak positive correlation
r represents
Strength and direction of the relationship.
