Answer:
As the Options are not given
6 + (-8)
It means Ahmed is on the Sixth floor, above the ground floor and then goes 8 floor Downwards which is 2 level below the ground floor.
The Answer in form of numbers is = -2
Because when we add a positive integer and a negative integer , we just subtract smaller integer from larger integer , and keep that sign before the result which the larger number bears.
6 + (-8)=
8 is larger integer which bears negative sign.
One integer is positive and another one is negative,
8 -6= 2
So, 6 + (-8) = -2 →→ 2 level below the ground level
Answer:
Step-by-step explanation:
The vertical displacement function is , where
is measured in meters and
in seconds. Ball hits the ground when
. That is:
Whose roots can be found by using the General Formula for Second-Order Polynomials:
Solutions of this polynomial are:
Only the first root is physically consistent.
Answer: <u>Last option</u>
Step-by-step explanation:
The z-scores give us information about how many standard deviations from the mean the data are. This difference can be negative, if the data are n deviations to the left of the mean, or it can be positive if the data are n deviations to the right of the mean.
To calculate the Z scores, we calculate the difference between the value of the data and the mean and then divide this difference by the standard deviation.
so
.
Where x is the value of the data, μ is the mean and σ is the standard deviation
In this case :
μ = 12 $/h
= 2 $/h
We need to calculate the Z-scores for and
Then for :
.
Then for :
.
Therefore the answer is:
Answer:
(A)6
Step-by-step explanation:
Given the quadratic expression:
We factorize:
Therefore, the missing number that will complete the factorization is 6.
