Answer:
Square root of 87.35 will be plotted between 9 and 10 as shown below.
Step-by-step explanation:
We are given that, 'The number line is numbered in tenths'
Also, the square root of 87.35 is given by,
That is, we have to plot the point 9.4 on the number line numbered in tenths.
As, 9.4 will lie between the points 9 and 10.
Thus, we get that square root of 87.35 will be plotted between 9 and 10 as shown below.
Answer:
Fred would take 33 days to save $ 70.95.
Step-by-step explanation:
The number of days () is directly proportional to the quantity of money saved (

Fred would take 33 days to save $ 70.95.
Answer:
x²+4x+5
Step-by-step explanation:
i provided a picture explanation.
The given equation is the best line that approximates the linear
relationship between the midterm score and the score in the final exam.
Reasons:
The given linear regression line equation is; = 25.5 + 0.82·
Where;
= Final exam score;
= The midterm score;
AJ score in the first test, = 90
AJ's actual score in the exam = 99
Required:
The value of AJ's residual
Solution:
By using the regression line equation, we have;
The predicted exam score, = 25.5 + 0.82 × 90 = 99.3
∴ AJ's residual = 99.3 - 99 = 0.3
AJ's residual = 0.3
Therefore, the correct option is option E;
