Suppose a bike wheel has a diameter of 70 cm and the rider completes one cycle in

fenix001 [56]

Answer:

Step-by-step explanation:

radius 70/2=35 cm

circumference=2πr=2π×35=70π cm

time taken to complete one revolution=0.8 s

or distance covered in 0.8 s=70π

distance covered in 1 s=70π/0.8=700 π/8=175 π/2 s=87.5 π≈274.9 cm

speed=274.9 cm/s=2.749 m/s

Step-by-step explanation:

We have to use Bayes Theorem in solving this problem.

This theorem's formula is:

P(A | B) = $\frac{P(A and B)}{P(B)}$

Where the " | " means <u><em>"given that"</em></u>.

For our problem, using bayes theorem, we can write:

P(Student has lice | positive ) = $\frac{P(StudentHasLice and Positive)}{P(Positive)}$

P(Positive) = 0.1692 + 0.0492 = 0.2184
P (Student has Lice & Positive ) = 0.1692

So P(Student has lice | Positive ) = $\frac{0.1692}{0.2184}=0.7747$

One angle of a triangle measures 136º. The other two angles are congruent.

WINSTONCH [101]

Answer:

22°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + x + 136° = 180°

2x + 136° = 180° ( subtract 136° from both sides )

2x = 44° ( divide both sides by 2 )

x = 22°
