Answer:

I think its  

Step-by-step explanation:

I think its a because the IQR is the third quartile minus the first quartile (third-first=IQR)(the first is the middle number between the minimum and median and the third quartile is the middle number between the median and the maximum)so anyway it just makes sense that the answer would be B

The best way to achieve significant increases in interest after all in a savings account is through?
Alekssandra [29.7K]

Answer: The answer is (d) Compounding.

Step-by-step explanation:  We are given four options out of we are to select the best way through which we can achieve significant increases in interest after all in a savings account.

Increases in principle and increases in time will not give the result, because we are talking about a fixed amount of money for a fixed time.

Also, increases in interest is not in our hand.

So, only we can do is compounding. Here, in same amount of money and time, the rate of interest will automatically increase.

Thus, the correct option is (d) Compounding.

Given that 2sin^2 theta + sin theta -1 = 0, find the two values for sin theta.
Lisa [10]
2sin^2 θ + sin θ - 1 = 0
2sin^2 θ + 2sin θ - sin θ - 1 = 0
2sin θ(sin θ + 1) - 1(sin θ + 1) = 0
(2sin θ - 1)(sin θ + 1) = 0
2sin θ - 1 = 0 or sin θ + 1 = 0
sin θ = 1/2 or sin θ = -1

The two values of sin θ are 1/2 and -1

The volume of a swimming pool is 4x^3 - 20x^2 + 3x - 15 . what is one of the dimensions of the pool
maxonik [38]

Answer:

Height = x - 5 --- one of the dimension

Step-by-step explanation:

Given

Volume = 4x^3 - 20x^2 + 3x - 15

Required

The side dimension

Factorize the given expression

Volume = 4x^2 (x- 5) + 3(x - 5)

Factor out x - 5

Volume = (4x^2  + 3)(x - 5)

Volume is the product of base area and height'

Hence:

Area = 4x^2 + 3

Height = x - 5
