The sample mean for the number of years worked is , and % of the employees in the sample worked for the company for at least 10 years. Round your answers to the nearest integer.
The sample mean for the number of years worked is 14, and 73% of the employees in the sample worked for the company for at least 10 years.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
The mean = (sum of service years) / employees in the sample worked
[tex](8+13+15+3+13+28+4+12+4+26+29+3+10+3+17+13+15+15+23+13+12+1+14+14+17+16+7+27+18+24) /30\\= (417 / 30)[/tex]
= 13.9 years
= 14 years
The percentage of employees who have worked for at least 10 years :
The number of employees with service years ≥ 10 years
= 22 employees
Total number of employees
Percentage (%) = (22 / 30)
= * 100%
= 0.7333 x 100%
= 73.33% = 73%
Therefore, The sample mean for the number of years worked is 14, and 73% of the employees in the sample worked for the company for at least 10 years.

On March 26, Samuel Griffin deposited $20,000 in a savings account that pays 5 5% interest compounded daily until July 24.
5 days in march.
31 days in May
30 days in June
24 days through July
rate of 5% each day.
so about 90 days of interest daily.
So 5% of 20,000
5 percent *20000

= (5*20000)/100
= 100000/100 = 1000

Which of the following functions best fits the data shown in the scatterplot below? y=100x+2 / y=20x^2+10 / y=4^x+8 / y=2^x+5
The equation of the scatter plot is (a) y = 100x + 2
How to determine the equation of the scatterplot?The line of best fit of the scatter plot passes through the points
(x,y) = (0,2) and (1,102)
The equation is then calculated as:
[tex]y = \frac{y_2 -y_1}{x_2 -x_1}(x - x_1) + y_1[/tex]
Substitute known values in the above equation
[tex]y = \frac{102 -2}{2-1}(x - 0) + 2[/tex]
Evaluate the expression on the right-hand side
y = 100x + 2
Hence, the equation of the scatter plot is (a) y = 100x + 2

Which of these correctly explains the solution of the system of equations shown below?
2 x + 3 y = 6
x + 3 y = 12
a) The values of x = -6 and y = 6 satisfy both the equations; therefore, (-6, 6) is the solution
b) The equations have y-intercepts at 2 and 4; therefore (2, 4) is the solution
c) The equations have x-intercepts at 3 and 12; therefore (3,12) is the solution
d) the lines representing the equations intersect at x = 1 and y = 0; therefore (1,0) is the solution
The values of x = -6 and y = 6 satisfy both the equations; therefore, (-6, 6) is the solution. The correct option is a)
Simultaneous linear equationFrom the question, we are to determine the solution of the given system of equations
The given system of equations are
2 x + 3 y = 6 ------- (1)
x + 3 y = 12 ------- (2)
From equation (2)
x + 3y = 12
Then, we can write that
x = 12 - 3y --------- (3)
Substitute this into equation (1)
2x + 3y = 6
2(12 -3y) + 3y = 6
24 - 6y + 3y = 6
24 -3y = 6
24 - 6 = 3y
18 = 3y
∴ y = 18/3
y = 6
Substitute the value of y into equation (3) to get the value of x
x = 12 - 3y
x = 12 -3(6)
x = 12 - 18
x = -6
∴ x= -6 and y = 6 ; Thus, (-6, 6) is a solution
Hence, the values of x = -6 and y = 6 satisfy both the equations; therefore, (-6, 6) is the solution. The correct option is a)
