Yes, the doctor made a mistake. He should have wrote 67.2 pounds on George's chart. Because when rounded it would be 67.2.

Hope this helps.

Part 1: Multiple Choice

Option C: (0,125) is the y - intercept.

Explanation:

The given function is $f(x)=x^3-5x^2-25x+125$

We need to determine the y - intercept.

<u>The value of y - intercept:</u>

The y - intercept is the value of y when x = 0

The y - intercept of the function can be determined by substituting x = 0 in the function.

Hence, let us substitute x = 0 in the function $f(x)=x^3-5x^2-25x+125$ , we have,

$f(x)=(0)^3-5(0)^2-25(0)+125$

Simplifying the terms, we get;

$f(x)=0-5(0)-25(0)+125$

$f(x)=0-0-0+125$

$f(x)=125$

Thus, the value of y is 125.

Hence, the y - intercept is 125.

Therefore, the coordinates of the y - intercept are (0,125)

Hence, Option C is the correct answer.

In a game, the player wins if he rolls a 2 on a

natima [27]

Since the die is 6 sided, there’s a 1/6 chance he’ll roll a 2. If we divided 100 by 6, it is a 17% success rate.
24 x 17% is 4.08.

He will probably roll successfully 4 times out of 24

Double check: 4/24 can be simplified to 1/6, which is the original probability.
