Answer:

The y-intercept in the model represents the base salary

Step-by-step explanation:

In regression analysis, the y-intercept refers to the point where a regression line crosses or cuts the y-intercept. At this point, the value of the explanatory variable X is usually 0.

In the model, the explanatory variable x is Ashley's total sales for the year. On the other hand the dependent variable is the annual salary which depends on total sales.

Substituting x with 0 in the regression model yields;

y = 0.2(0) + 25,000

y = 25,000

The y-intercept is thus 25,000 which is simply the salary earned in the absence of sales. This is simply the basic salary.

DedPeter [7]

Answer:

32$ < x < 48$

Step-by-step explanation:

Erika estimates that her destination is between 200 and 300 miles away.

When we divide 200 with 25 miles we get 200/25 = 8 gallons

When we divide 300 with 25 miles we get 300/25 = 12 gallons

When we multiply 8 · 4 = 32$ we get amount of money for destination

200 miles  x = 32$

When we multiply 12 · 4 = 48$ we get amount of money for destination

300 miles  x = 32$

Since that the estimate destination is between 200 miles and 300 miles

then the best estimate for the amount of money is between

32$ < x < 48$

A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6
Leto [7]
<h2>Number of bacteria after 6 days is 2313</h2>

Step-by-step explanation:

Population after n days is given by

              P_n=P_0(1+r)^n

Initial population, P₀ = 1000

Increase rate, r = 15 % = 0.15

Number of days, n = 6

Substituting

             P_n=P_0(1+r)^n\\\\P_6=1000(1+0.15)^6\\\\P_6=1000(1.15)^6\\\\P_6=1000\times 2.313\\\\P_6=2313

Number of bacteria after 6 days = 2313
