Answer:
11375
Step-by-step explanation:
From the table :
Proportion of people who bought program :
Total number of items bought = (68 + 19 + 22 + 91) = 200
Number of programs = 91
Proportion of programs = 91 / 200 = 0.455
Of 25000 attendees ; expectd number of program sale :
0.455 * 25000 = 11375
Answer:
3. It is likely.
Step-by-step explanation:
Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side
<u>Then the areas covered will be as:</u>
- point 20 = πr² = S
- point 15 = π(2r)² - πr² = 3πr² = 3S
- point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
- point 5 = π(4r)² - π(3r)² = 7πr² = 7S
Total area of the dartboard is S+3S+5S+7S = 16S
The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S
The probability of scoring at least 10 points is:
As it is between 1/2 and 1, the probability is in 'likely' region
<u>So the correct answer choice is:</u> 3. It is likely

Answer:
y= 9.50x + 22.50
Step-by-step explanation:
x= number of shirts bought
9.50 is the cost for one shirt, plus the flat fee of 22.50$
Answer:
Richard is twenty-six and Teo is ten.
Step-by-step explanation:
Let x = Richard's age and y = Teo's age
x = 2y + 6
(2y + 6) + y = 36
3y + 6 = 36
-6 -6
3y = 30
y = 10
x = 2(10) + 6
x = 20 + 6
x = 26
Richard is 26
Teo is 10
