Answer:
The area formulas for a triangle and a parallelogram require multiplying base by height.
A rectangle and parallelogram with the same base and height will have the same area.
Answer:
The distance between the two points is
Step-by-step explanation:
The formula of the distance between two points (x1, y1) and (x2, y2) is
d =
∵ The points are (-1, 3) and (4, 2)
∴ x1 = -1 and x2 = 4
∴ y1 = 3 and y2 = 2
→ Substitute them in the formula of the distance above
∵ d =
∴ d =
∴ d =
∴ d =
∴ d =
∴ The distance between the two points is
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
Answer:
24 boxes
Step-by-step explanation:
The processor knows that the standard deviation of box weight is 0.5 pound
We are supposed to find How many boxes must the processor sample to be 95% confident that the estimate of the population mean is within 0.2 pound
Formula of Error=
Since we are given that The estimate of the population mean is within 0.2 pound
So,
z at 95% confidence level is 1.96
Hence the processor must sample 24 boxes to be 95% confident that the estimate of the population mean is within 0.2 pound
Answer:
P = 350 feet
Step-by-step explanation:
P = 2L + 2W
W = 70 feet
L = 105 feet
plug in values:
P = 2(105) + 2(70)
P = 210 + 140
P = 350 feet
