A triangle has side lengths that are 8 cm, 15 cm, 17 cm. Is this a right triangle?

1 answer:

5 0

Answer: A triangle has side lengths of 8 cm, 15 cm, and 17 cm. classify it as acute, obtuse, or right. Well, since 8^2 + 15^2 = 17^2, the sides fit the Pythagorean Theorem and thus it must be a right triangle.

Step-by-step explanation:

The distance around the wheel of a truck is 9.42 feet .what's the diameter of the wheel

kap26 [50]

To solve this problem, you must follow the proccedure that is shown below:

1. You need to apply the formula for calculate the perimeter of a circle, which is:

P=2πr

P is the perimeter of the circle (P=9.42 feet).
r is the radius of the circle.

2. Now, you must clear the radius "r" from P=2πr, as below:

P=2πr
r=P/2π

3. When you substitute the values, you obtain:

r=P/2π
r=9.42 feet/2π
r=1.49 feet

4. Now, you can calculate the diameter (D):

D=2r
D=2(1.49 feet)
D=2.98 feet

What's the diameter of the wheel?

The answer is: 2.98 feet

In a reliability test there is a 42% probability that a computer chip survives more than 500 temperature cycles. If a computer c

Strike441 [17]

Answer:

The probability is $P(B' n A ' ) =$ 16%

Step-by-step explanation:

From the question we are told that

A is the event that the chip was "made by company A"

B is the event that a chip "survives 500 temperature cycles"

The probability that a computer chip survives more than 500 temperature cycles is

$P(B) = 42$ % $= 0.42$

The probability that does not survive more than 500 temperature cycles and it was manufactured by company A is $P(A | B' ) = 0.73$

The probability that the computer chip is not manufactured by company A and does not survive more than 500 temperature cycles is mathematically evaluated as

$P(B' n A ' ) = P (B' | A' ) P(B ')$
