Answer:
could not be the same
Step-by-step explanation:
Given that approximately US drivers are agewise as follows:
<25 13.2
25-45 37.7%
>45 49.1%
Observations are made for a sample of 200 fatal accidents.
Let us create hypotheses as
(Two tailed chi square test at 5% significance level)
Age <25 25-45 >45
Expected 13.2 37.7 49.1 100
Observed 42 80 78 200
Expected no 26.4 75.4 98.2 200
Chi square 9.218181818 0.280636605 4.155193483 13.65401191
df = 2
p value = 0.001084
Since p <0.05 we reject null hypothesis
At the 0.05 level, the age distribution of drivers involved in fatal accidents within the state could not be the same as the age distribution of all US drivers as there seems to be significant difference.
The equivalent expression to the given expression is 
<h3>What is an algebraic expression?</h3>
Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).
From the given expression, we are to determine an expression that is equivalent to:
To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.
By doing so, we have:

try the answer b just did test but I think your order is different
If you would like to know how many students were in each class, you can calculate this using the following steps:
4 buses<span> * x + 8 students = 220 students</span>
4 * x + 8 = 220
4 * x = 220 - 8
4 * x = 212 /4
x = 212 / 4
x = 53
<span>53 students were in each bus.</span>
