Answer:
Option B. The Lateral area is 692 cm2
Step-by-step explanation:
<u>Verify each statement</u>
case A) The area of the base is 384 cm2
The statement is False
Because
The area of the base is
case B) The Lateral area is 692 cm2
The statement is True
Because
we know that
The lateral area is equal to the area of its three triangular lateral faces
so
case C) The surface area is 740 cm2
The statement is False
we know that
The surface area is equal to the lateral area plus the area of the base
so
we have
substitute
case D) The area of each congruent face is 264 cm2
The statement is False
The area of each congruent face is equal to
20x 10 to the third power equals 20000
Answer:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
The probability of finding a value higher than x is:
Average repair time of 2 hours
This means that
What is the probability that the repair time takes between 2 to 4 hours
More than 2:
Less than 4:
Between two and four:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
Answer: 169'
Step-by-step explanation:
Since the expression for ordering brushes for an art class is given as 5c - 1, where c is the class limit.
Therefore, when the class limit is 34, the expression evaluated will then be:
= 5c - 1
= 5(34) - 1
= 170 - 1
= 169
Therefore, 169 brushes were ordered.
3/4f+1/8=3/4(f+8) <--- Given
3/4f+1/8=3/4f+6 <--- Distributive Property
This is an incorrect statement, so F does not exist
Hope this helps!
