Answer:
The answer is B (110.0 cm).
Step-by-step explanation:
If you multiply the diameter 35 by pi (3.14) you get 109.9.
When you round to the nearest tenth the answer 110.
Take the first bracket and it's multiplication, 3(2a+5)
You expand my multiplying everything inside the bracket by the number outside.
3*2a = 6a
3*5 = 15
Then multiply out the second bracket, 5(a-2)
5*a = 5a
5*-2 = -10
So now you have 6a + 15 + 5a - 10
Simplify it by collecting like terms, and you have:
11a + 5
And that's the answer, hope I helped!
Answer:
mean = $11.15
median = $11.30
mode = $9.90, $10.70, $11.90, $12.05
Step-by-step explanation:
Ordered from smallest to largest
9.89, 10.71, 11.90, 12.06
The mean is the middle number.
There are two numbers in the middle so you have to add them together and divide by 2.
(10.71 + 11.90)/2 = 11.305
rounded 11.30
Mode is the number that appears the most. All of the prices are listed once. They are all the mode.
Mean is (10.71+11.90+9.89+12.06)/4 = 11.14
round 11.15
