<u>Final Answer:</u>
x = 20
<u>Step-by-step explanation:</u>
we'll be using the pythagorean theorem method, in this triangle the missing letter is a.
formula:
a = x
b = 21
c = 29
a =
a = (note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)
a =
a = 20
x = 20
Answer:
Option 3) The expected Exam 3 score for someone that made a 0 on Exam 1 is a 50.57.
Step-by-step explanation:
We are given the following in the question:
The above equation is a linear regression equation to predict the Exam 3 score of students in STA 2023 based on their Exam 1 score.
: The dependent variable, Exam 3 score
x: The independent variable, Exam 1 score
Comparing to general linear equation,
We get,
m = 0.4845, c = 50.57
where
c is the y - intercept and the score in exam 3 when exam score is 0.
m is the slope and tells us about the rate of change.
When exam 1 grade is increased by 1, we can write,
Thus, the y-intercept for the given equation can be interpreted as
Option 3) The expected Exam 3 score for someone that made a 0 on Exam 1 is a 50.57.
