Answer:
1 1/5
Step-by-step explanation:
first you move the decimal to spaces to the left.
1.50
Then you change the decimal to a fraction
1 50/100
This is because .50 is in the hundreths spot
Then you simplify -
1 5/10
we simplify again
1 1/5
thats your answer
The quadratic regression equation of the table of values is y = 0.71x² - 5.04x + 3.76
<h3>How to determine the regression equation?</h3>
The table of values is given as:
x: 0 1 2 3 4 5 6
y: 4.1 -0.9 -3.9 -5.1 -4.1 -4.1 -1.1
To determine the quadratic regression equation, we make use of a graphing calculator
From the graphing calculator, we have the following calculation summary:
a = 0.7, b = -5.04 and c = 3.76
A quadratic regression equation is represented as:
y = ax² + bx + c
Hence, the quadratic regression equation of the table of values is y = 0.71x² - 5.04x + 3.76

Answer:
domain : ] -∞ , 2]
Step-by-step explanation:
the value of 2-x must be more than or equal to 0
because you there is no square root for negative number
2-x ≥ 0
x ≤ 2
Answer:
11,495 and 6,030
Step-by-step explanation:
1. A=1/2(a+b)h
2A=(a+b)h
2Ah=a+b
2Ah-b=a
a=2×360×16-25
a=11,495
2. b=2Ah-a
b=2×252×12-18
b=6,030
