Answer:
$1.60
Step-by-step explanation:
12.73÷8 = 1.59125
(1.59 rounded is 1.60)
Answer:
(-1.5, 0) or -1.5
Step-by-step explanation:
The answer if -1.5 because the line hits the x-axis one time and hits it at the point of -1.5. The slope of the line is 2 and the y-intercept is 3, when graphed, you should also see when the line hits the x-axis
Answer:
b. 2.01 < σ < 2.81
Step-by-step explanation:
The 90% confidence interval for the population standard deviation is calculated as:
< σ < 
Where n is equal to 51, s is equal to 2.34, 
is 10%, 
is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of 
in the right tail and 
is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of 
in the right tail.
So, replacing n by 51, s by 2.34, by 67.50 and by 34.76, we get that the The 90% confidence interval is equal to:
< σ <
2.01 < σ < 2.81
Answer:
(1,2) is a solution to both equations
Step-by-step explanation:
To determine if (1,2) is a solution to both equations, substitute into the equation and see if it is true
2x+y =4
2(1) + 2 =4
2+2 =4
4=4
true
y =3x-1
2 = 3(1) -1
2 =3-1
2=2
true
Since both statements are true
(1,2) is a solution to both equations
