6^3. 216. When using chance, take the possible outcomes(six for a die) and raise it to the power of the number of repetitions.
Answer:
0.9953, 3.3629<x<4.0371
Step-by-step explanation:
Given that slader the internal revenue service claims it takes an average of 3.7 hours to complete a 1040 tax form, assuming th4e time to complete the form is normally distributed witha standard devait of the 30 minutes:
If X represents the time to complete then
X is N(3.7, 0.5) (we convert into uniform units in hours)
a) percent of people would you expect to complete the form in less than 5 hours
=
b) P(b<x<c) = 0.50
we find that here
c = 4.0371 and
b = 3.3629
Interval would be
Answer:
Step-by-step explanation:
y = x² + 4x is an up-opening parabola with x-intercepts 0 and -4.
y ≥ 0 when x≤-4 or x≥0
range: (-∞,-4)∪[0,+∞)
Answer:
The third graph, the top right graph
Step-by-step explanation:
A function when determined graphically is a graph that passes the straight line test, which means if there is any two points on the graph which you can plot a vertical straight line going through both of them it is not a function. If 1 x value is equal to 2 y values, it is not a function.
Answer:
18/5 or 36 necklace
Step-by-step explanation:
kendell made 2/5 necklace in 1/9 hours
how many will she make in 1 hour
hmmm?
2/5 = 1/9
x = 1
2/5 × 1 = 1/9x
x = 2/5 ÷ 1/9
x = 2/5 × 9/1
x = 18/5
x = 3.6necklace
