Slope intercept form:
The equation of straight line is given by:
....[1]
where, m is the rate or slope and b is the initial value of y-intercept.
As per the statement:
A certain species of tree grows an average of 3.1 cm per week.
Let x be the number of week and y represents the weekly height of the tree.
then;
" tree grows an average of 3.1 cm per week." translated to 3.1 x
It is also given that:
the measurements begin when the tree is 400 centimeters tall.
⇒y(0) =b = 400 cm
Substitute the given values in [1] we have;
Therefore, an equation for the sequence that represents the weekly height of this tree in centimeters is,

Dividing by 50 is the same as multiplying by 1/50, which is equivalent to 2/100.
The fraction 2/100 means we'll double 24000 to get 48000. Then remove 2 zeros at the end to get 480. The removal of two 0's is due to the division by 100.
Therefore, 24000/50 = 480
---------------
Dividing by 5 will follow a similar pathway. We can multiply by 1/5 aka 2/10
24000/5 = 24000*(1/5) = 24000*(2/10) = 48000/10 = 4800
Notice the numerator doubled to 48000, and then we remove a zero at the end.
All of this can be done using pure mental math only. Each answer can be confirmed with a calculator.

Answer:
Option B is correct.
Miguel should study for the Science quiz as he will do worse in that quiz by guessing.
Step-by-step explanation:
Miguel has to take two quizzes
1) 4 true or false questions on History with a 0.5 chance of acing the quiz
Expected number of correct questions = np
n = number of questions
p = probability of acing the test
Expected number of correct questions = 4 × 0.5 = 2
2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.
Expected number of correct questions = 0.2 × 3 = 0.6
It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.
Answer:
He is correct
