Step 2
The probability that someone scored 21.9 or less is :
Answer : 
The length, width, and area will be 25m, 15m, and 375m².
<h3>How to calculate the area?</h3>
From the information given, the scale in the drawing is 2cm : 5m and the length and width are given as 10cm and 6cm respectively.
Length = 10cm = 10 × 2.5 = 25m
Width = 6cm = 6 × 2.5m = 15m
Area = Length × Width
Area = 25 × 15
Area = 375m²
Therefore, the area is 375m².

Answer:
A. y = x+10
Step-by-step explanation:
The original test score is x
And in the next assignment it is 10 more means,
x + 10
If the new score is y then it should be equal to the above solution.
Hence, answer is <u>y</u><u> </u><u>=</u><u> </u><u>x</u><u>+</u><u>10</u><u>.</u>
If you look at the data, you can see that every y value is opposite to the corresponding x- value.
So, equation can be written as
y = [-] x or y=[-1]x
