A probability experiment is conducted in which the sample space of the experiment is S={7,8,9,10,11,12,13,14,15,16,17,18}, event
o-na [289]
Answer:
F or G = {7,8,9,10,11,12,13,14}
n(F or G) = 8
n(S) = 12
By counting the no. of outcome
P(F or G) = n(F or G) / n(S)
P(F or G) = 8 /12
P(F or G) = 2/3
By using the general addition rule
P(F or G) = P(F) + P(G) - P(F and G)
= 6/12 + 4/12 - 2/12
= 2/3
The amount of tin in the alloy is calculated by multiplying the weight of the allow with the percentage of tin. This is shown below,
(20 lbs) x (0.15) = 3 lb
Thus, the alloy contains 3 lbs tin. The answer is the first choice.
Answer:
g(x) = (x + 3)^2
Step-by-step explanation:
When a function is shifted to the left or right we can think of a change of units, like a new independent variable is used.
If we have a quadratic function
and the graph is shifted 3 units to the left, then we can think of a new unit u that is:
The vertix of this parabola, that happens for u=0, happens for x=-3, as the graph is shifted 3 units to the left.
Then, the relation between u and x is:
We can use this relation in the new graph and replace u as:
Answer:
12.96
Step-by-step explanation:
since it is a square, both sides are equal. to find the area of any square, it is the side squares. since you are given what the area is, simply square root 168.
which is about 12.96
