The Function having highest Degree of Four given here is :
As the given function has highest degree of four, it has maximum of four roots.
As complex and Irrational root occur in pairs, so There are many possibilities
1. Two Complex or Irrational + Two Real
2. Four real roots
3.All roots are complex or irrational
By looking at the options described below, it means it has four real roots.
It will cut X axis at four points.
With the help of Desmos you can directly find the solution of this problem, but without desmos Graphing, we first have to check by Taking different points on the curve whether graph of function described here is correct or not, i.e by method of increasing and decreasing formula of a function.The method to check is
If there are two points on the curve i.e
1. Increasing Function.
2. Decreasing Function.
Option (4) is true .
Answer:
Step-by-step explanation:
Given:
Solving for :
A)
B)In 200 times he can hit 59 times !
<u>Step-by-step explanation:</u>
Here we have , A baseball player got a hit 19 times in his last 64 times at bat. We need to find the following :
a. What is the experimental probability that the player gets a hit in an at bat?
According to question ,
Favorable outcomes = 19
Total outcomes = 64
Probability = (Favorable outcomes)/(Total outcomes) i.e.
⇒
⇒
b. If the player comes up to bat 200 times in a season, about how many hits is he likely to get?
According to question , In 64 times he hit 19 times . In 1 time there's probability to hit 0.297 times! So ,In 200 times he can hit :
⇒
⇒ Hit = 59.36
Therefore , In 200 times he can hit 59 times !
