The number of E.coli bacteria cells in a pond of stagnant water can be represented by the function below, where A represents the

liq [111]

Answer:

<u>Option B. 59%</u>

Explanation:

The function that represents the number of E.coli bacteria cells per 100 mL of water as the time t years elapses is:

$A(t)=136(1.123)^{4t}$

The base, 1.123, represents the multiplicative constant rate of change of the function, so you just must substitute 1 for t in the power part of the function:

$rate=(1.123)^{4t}=(1.123)^4=1.590$

Then, the multiplicative rate of change is 1.590, which means that every year the number of E.coli bacteria cells per 100 mL of water increases by a factor of 1.590, and that is 1.59 - 1 = 0.590 or 59% increase.

The regression equation for predicting number of speeding tickets (Y) from information about driver age (X) is Y = -.065(X) + 5.

ivolga24 [154]

Answer:

c. 4.27

Step-by-step explanation:

We have been given the regression equation of for predicting number of speeding tickets (Y) from information about driver age (X) as $Y=-0.065(X)+5.57$ .

To find the predicted number of tickets for a twenty-year-old, we will substitute $X=20$ in our given equation.

$Y=-0.065(20)+5.57$

$Y=-1.3+5.57$

$Y=4.27$

Therefore, the predicted number of tickets for a twenty-year-old would be 4.27 tickets.
