Assuming a linear model of the savings as a function of time, what is the meaning of the slope of the line of best fit for the graph of the data?
Answer:
Step-by-step explanation:
The meaning of the slope of the line of best fit for the graph of the data is that for each month the balance in the Saving account is increasing at a constant rate.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units

A track is 400 yards around how many full laps does tyler need to run if he wants to run atleast 2 milies
Answer:
17.6 laps
Step-by-step explanation:
Total distance to be covered = 2 miles
distance coved in each lap = 400 yards
We know that 1 mile = 1760 yards
therefore, 4 miles will make = 4×1760
= 7040 yards.
Number of laps to be taken
= Total distance to be covered ÷ distance coved in each lap
= 7040/400 = 17.6 laps
Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.

The measure of an angle is 2.8.what is the measure of its complementary angle
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°
