Answer:
150
Step-by-step explanation:
Rolling a 2, 3, or 4 should happen approx 60% of the time
250 x 60%= 150
ANSWER
EXPLANATION
The dimensions of a matrix is of the form:
The dimensions of the first matrix is
The dimensions of the second matrix is
Since the inner products are the same,the outer products give the dimensions of the product of the two matrices.
Therefore the dimensions of the product is a 2×2 matrix.
X(4*1) because I’m just doing what I’m told.
Caution: you need to use the same units of measurement throughout. If the spring stretches by 21 cm when a 135 newton object is attached, then you must ask for the mass (in newtons) of a fish that would stretch the spring by 62.1 cm.
We will need to assume that the spring is not stretched at all if and when no object is attached to the spring.
Write the ratio
21.0 cm 135 newtons
------------- = --------------------
62.1 cm x
Solve this for x. This x value represents the mass of a fish that would stretch the spring by 62.1 cm. You can cancel "cm" in the equation above:
21.0 135 newtons
------ = --------------------
62.1 x
Then 21.0x = (62.1)(135 newtons). Divide both sides of this equation by 21.0 to solve it for x.
