This is a problem of Binomial Probability.
Success Rate = p = 0.48
Sample Size = n = 55
Number of success = x = 22
We are to find

i.e. that probability that atleast 22 adults use the smartphone in meetings or class.
The probability can be calculated using the Binomial Calculators and it comes out to be 0.907.
This means there is
0.907 or 90.7% probability that there are atleast 22 adults among the 55 selected adults who use cell phones in meeting or class.
Answer:

Step-by-step explanation:
Refer to physics equation
, where
is angular velocity.
Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:

Now substitute
and
into
:

Answer/Step-by-step explanation:
✅m<1 = 180 - 52° = 128° (consecutive interior angles)
✅m<2 and 52° are alternate interior angles. Alternate interior angles are congruent.
Therefore:
m<2 = 52°
✅m<3 and 47° are alternate interior angles. Alternate interior angles are congruent.
Therefore:
m<3 = 47°
✅m<4 = 180 - m<3 (linear pair)
m<4 = 180 - 47 (substitution)
m<4 = 133°
✅m<5 = 180 - (52 + 47) (angles on a straight line)
m<5 = 81°
Answer:
It would be 72% trust me it is correct because this level of questions seems a little to young for me lol
