Answer:
0.72868
Problem Statement:
23% of the cars a certain automaker manufactures are silver. Below is the probability distribution for the number of
silver cars sold by a car dealer in the next five car sales.
No. of Silver Cars 0 1 2 3 4 5
Probability 0.27068 0.40426 0.24151 0.07214 0.01077 0.00064
Step-by-step explanation:
To find the probability that the dealer sells between one and four silver cars, we need to add the probabilities of him selling 1,2,3 or 4 cars.
<u>Probability that the dealer sells between and including one and four silver cars</u>= 0.27068+ 0.40426 + 0.24151 + 0.07214 =0.72868
Answer:
The area of trapezoid is 32 inches^2
Step-by-step explanation:
Parallel base 1 = a = 3 inches
Parallel base 2 = b = 5 inches
Height of trapezoid = 8 inches
We need to find area of trapezoid
The formula used is: 
Now putting the values and finding area of trapezoid
So, the area of trapezoid is 32 inches^2
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.
A) For each year that kevin has had the tree, it grew 1 foot. Therefore for every 1 year that passes, kevin’s tree grows 1 foot.
B) 5+T= H
