Answer:
The italian goalie: 85.7%
Step-by-step explanation:
17 / 20 = 85% (Russian)
12 / 14 = 85.7% (Italian)
Step 1: Find f'(x):
f'(x) = -6x^2 + 6x
Step 2: Evaluate f'(2) to find the slope of the tangent line at x=2:
f'(2) = -6(2)^2 + 6(2) = -24 + 12 = -12
Step 3: Find f(2), so you have a point on y=f(x):
f(2) = -2·(2)^3 + 3·(2)^2 = -16 + 12 = -4
So, you have the point (2,-4) and the slope of -12.
Step 4: Find the equation of your tangent line:
Using point-slope form you'd have: y + 4 = -12 (x - 2)
That is the equation of the tangent line.
If your teacher is picky and wants slope-intercept, solve that for y to get:
y = -12 x + 20

Using the given histogram, we have that 90% of the players in the sample have scores that are less than 2300.
<h3>What is the missing information?</h3>
This problem is incomplete, but researching it on a search engine, we have that the histogram states as follows:
- 6 of these players have scores between 300 and 700.
- 6 of these players have scores between 700 and 1100.
- 13 of these players have scores between 1100 and 1500.
- 14 of these players have scores between 1500 and 1900.
- 6 of these players have scores between 1900 and 1300.
- 5 of these players have scores between 2300 and 2700.
It asks the proportion of players in the sample with <u>scores that are less than 2300</u>.
<h3>What is an histogram?</h3>
An histogram is a graph that shows the <u>number of times each element of x was observed.</u>
Above, we already gave the amounts presented by histogram, and we have that 45 out of 50 players have <u>scores that are less than 2300</u>, hence the proportion is given by:
p = 45/50 = 0.9.

Answer:
4.45
Step-by-step explanation:
- it is ordered from highest to lowest
1,99 1,99 3.2 <u> 4,36 4,54 </u> 4,78 4,8 4,83
(2 numbers remain as medium)
- is added and divided by 2
4,36
<u>4,54</u>
<u>8,90/2= </u> 4.45
i hope i have help you :)
