Yes it have one right angle ..
Answer:
l = 626.4/bh
Step-by-step explanation:
A triangular prism have a base that is triangular in shape. The volume of a prism has the volume represented as follows.
volume = Al
where
A = Base area
l = width
Since the base is a triangle the base area will be the area of a triangle. Therefore,
volume of a triangular prism = 1/2bh l
where
b = base of triangle
h = height of triangle
volume = 313.2 ft³
313.2 = 1/2bh l
Make the width(l) subject of the formula
multiply both sides by 2
626.4 = bhl
divide both sides by bh
l = 626.4/bh
l = 626.4/bh
recall l = width
FORMULA:
Length of arc PQ = 2πrΦ/360°
ANSWER:
Using formula,
2 × 22/7 × 7 × 80/360
44 × 2/9
88/9ft or 9.7ft
w = -4
6w + 2 = 9w + 14
Combine like variables by subtracting 9w and 2 from both sides
6w ( - 9w) + 2 ( - 2) = 9w ( - 9w) + 14 ( - 2)
-3w = 12
Divide both sides by negative 3 to separate the variable from any integers
(-3w = 12) / -3
w = -4
Answer:
18.88% probability that three or four customers will arrive during the next 30 minutes
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
Average rate of 6.4 per 30 minutes.
This means that
What is the probability that three or four customers will arrive during the next 30 minutes?
18.88% probability that three or four customers will arrive during the next 30 minutes
