Answer:
The matrix that represents the system of equations is:
Step-by-step explanation:
We will use the first column for x, the second to y and the last for the independent term.
We have:
Then, we can write the matrix to represent the system of equations as:
Answer:
79,213,229 ft3
Step-by-step explanation:
The volume of a pyramid is given by the following formula:
Volume = (1/3) * B * h
Where B is the base area and h is the height.
The side of the base is 754 feet, so the base area is:
B = 754^2 = 568516 ft2
Then, the volume of the pyramid is:
Volume = (1/3) * 568516 * 418 = 79213229.33 ft3
Rounding to the nearest cubic foot, we have:
Volume = 79,213,229 ft3
The answer will be 2/25 times 1/175 which would equal 14/1
Therefore, the answer is: the model car will be 14 inches long.
Answer:
b) 2.00
Step-by-step explanation:
For each name, there are only two possible outcomes. Either it is authentic, or it is not. The probability of a name being authentic is independent of any other name. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
She randomly selects five names from the list for validation.
This means that
40% of the names on the list are non-authentic
This means that
The expected (average) value of x is
The correct answer is given by option B.
