Answer:
<h2>25</h2>
Step-by-step explanation:
The rate of change of number of tree y on x branches of a tree is expressed as shown;
m = Δy/Δx where;
m is the rate of change
Δy is the change in number of leaves between 3 and 4
Δx is change in number of branches between 3 and 4
m = Δy/Δx = y₂-y₁/x₂-x₁
From table between 3 and 4, y₂ = 100, y₁ = 75, x₂ = 4, x₁ = 3
m = 100-75/4-3
m = 25/1
m = 25
<em>Hence the rate of change between 3 and 4 branches is 25</em>
Answer: y= -2/5x + 2
Step-by-step explanation:
Y= Mx + b
M is the slope
B is the y intercept
The y intercept will be out on the y axis
The slope will be rise over run ( do you first then do to the right!)
(6 - 3)/(-1 +4)= 3/3= 1 is the slope
y - 3 = x + 4
y = x + 7

<h2>
Answer:</h2>
Option: D is the correct answer.
D. 0.45
<h2>
Step-by-step explanation:</h2>
The results of the experiment are given as follows:
Coin Experiment Side of Coin Number of Tosses
Heads 18
Tails 22
This means that total 40 experiments were performed.
( Since 18+22=40)
Also, the number of times head turn up=18
Hence, the experimental probability of getting heads is:
Ratio of number of times head turn up to the total number of experiments performed.
Hence,

Hence, the experimental probability of getting head is:
0.45
