Answer:
The resulting value is 2.381
Step-by-step explanation:
Using the information presented in the question, we will calculate the evidence supporting the professor's hypothesis
Given that:
x₁ = 74,
n₁ = 36
s₁ = 8
x₂ = 68
n₂ = 36
s₂ = 10
The hypotheses can be outlined as:
The critical value is t₃₆+₃₆-₂,₀.₀₁ = t₇₀,₀.₀₁
thus,
t₃₆+₃₆-₂,₀.₀₁ = t₇₀,₀.₀ = 2.381
This implies a range of -2.381 to 2.381
Thus, we can support the professor's assertion.
To find the unit rate, we simply divide 4 by 2.
4 ÷ 2 = 2
This means the artist can complete 2 paintings every hour, establishing the unit rate as 2 paintings per hour.

The following table presents the conversion from degrees to gradients.
To calculate the slope, we take the difference between the two y-values (gradients) and divide it by the difference between the corresponding x-values (degrees).
For this purpose, we will use the initial and final points listed in the table. Therefore, the slope m is calculated as:
After rounding to two decimal places, the slope of the line converting degrees to gradients is 1.11
4.2x - 1.4y = 2.1
-1.4y = 2.1 - 4.2x
y = \frac{2.1 - 4.2x}{-1.4}
y = 3x - 1.5 <==
The length of the remaining piece measures 2 feet and 3 inches.
