Answer:
Vel. of the car = 3.33 meter per second.
Explanation:
In given graph, y axis represent the distance traveled by the car and x axis represent the time taken by car.
At time t = 30 seconds , distance traveled by the car is 100 meter
We know that,
Speed = 
speed = 
speed = 3.33 meter per second
That's the final answer.
I hope it wil help you.
Answer:
(a) Y = 129.3x (b) It is an estimate as it may not be a true reflection of a student's height
Step-by-step explanation:
(a) Estimate of the mean height is the sum of the heights of all the students divided by the total number of students.
The question however needs more information for its estimation as 129.3cm is representative and may be the mean height but it was not stated.
However, assuming it is the mean height,
Let the total number of students be x
while Y is the sum of all individual student heights
Mathematically, mean = Y/x
Therefore 129.3 = Y/ x
implying that Y = 129.3x
(b) It is an estimate because computation of the mean gives an average which may not be an exact value. For example, the mean here is 129.3 whereas there will be many heights greater than that and some lesser than that and obviously, there may be no student with height of 129.3 hence it is an estimate.
Answer:
The answer is D. (x-4)^2
Step-by-step explanation:
It has a horizontal shift of 4 to the right
Your answer should be B 10m because 4x10=40 and that's the bxh then you need to divided by 2 do it would be 20. And 20m^2 is your answer so B is your answer
Answer:
The commutative property of multiplication states that changing the order of the numbers we are multiplying, does not change the product.
