Answer:
The sample mean is 3.48 and the margin of error is 0.44.
Step-by-step explanation:
We know that the confidence interval is written in the form "x − E to x + E", meaning x: sample mean or estimator, and E: margin of error.
To calculate the mean, we can calculate the average of both bounds of the confidence interval:
With one of the bounds, we can calculate the margin of error E
2x - y = 7
y = 2x - 7 this line has slope = 2
Perpendicular lines, slope is opposite and reciprocal so slope = -1/2
Answer
A . -1/2
Que, i think 1, 5 go into 1
Answer:
-4
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
-4
1
= -4
θ =
arctan( ΔY ) + 360°
ΔX
= 284.03624346793°
ΔX = 5 – 2 = 3
ΔY = -8 – 4 = -12
Distance (d) = √ΔX2 + ΔY2 = √153 = 12.369316876853
The formula to get the volume of the triangular prism is;
V = B x H1 x H2
where;
B = is the area of the base of the triangle
H1 and H2= are the height of the triangle and the height of the triangular prism.
now, to find the area of the base simply use the formula
A = 1/2 B x H
where B is the value of the base and H is the value of the height of the triangle.
given the formula we can derive another formula to get the volume of the triangular prism.
V = 1/2 B x H1 x H2
given the formula, you can now substitute the values
.
V = 1/2 (3 in. x 8 in. x 9 in.)
V = 1/2 (216 in.^3)
V = (216 in.^3)/2
V = 108 in.^3 this is the final answer
