Answer:
Step-by-step explanation:
After 4 years the age of father is twice as old as his son . 5 years before the father age was 1 year more than triple age of his son.
so for this type of problem you would want to use the Pythagorean theorem. its a squared plus b squared equals c squared. you use this because it makes a triangle. c is your hypotenuse which is the longest side of the triangle. so you plug in what you can and solve to find the missing variable. in this case, the base equals the square root of 80 or approximately 8.94
Answer:
V-678.58
Step-by-step explanation:
it is volume so it is 678.58
The distribution is uniform for 50 ≤ x ≤ 52.
where x = minutes per class.
The probability P(x < 50.6) is the shaded portion of the distribution.
Its value is
(50.6 - 50)/(52 - 50) = 0.3
Answer:
The probability is 0.3 or 30%
Answer:
Let's define the symbols:
x < y
means that x is strictly less than y.
x ≤ y
means that x is less than or equal to y.
(both of these signs can be in the other direction, take that in mind).
A) " a is always less than another number b"
Here we should have:
a < b.
a is always less than the other number b.
This is not in the options, so i suppose that there is a mistake in the question.
B) The expression "above" is not shown here, so i will just writhe the correspondent expression for each option, and you can see which one matches with the expression above.
a) "The product between 3 and a number is no less than 9"
3*n ≥ 9.
b) "The product between 3 and a number is greater than 9."
3*n > 9
c) "The product between 3 and a number is no more than 9"
3*n ≤ 9
d) "The product between 3 and a number is less than 9"
3*n < 9
