Answer: 0.0575
Step-by-step explanation:
Binomial probability distribution :-
, where P(X) is the probability of getting success in x trials, n is the total number of trials and p is the probability of success in each trial ( in decimal ).
Given : The probability that adults use smartphones in meetings or classes = 0.57
Sample size : n= 8
Now, the probability that exactly 2 of them use their smartphones in meetings or classes :-

Hence, the required probability = 0.0575
The whole thing is 360°.
360= 85+95+118+x
360= 298+x
subtract 298 from both sides
62=x
Answer:
85 cm
Step-by-step explanation:
the strut forms a right triangle with the end of the pole.
let the ends of the strut be x from the top of the pole . then
using Pythagoras' identity with 2 legs x and hypotenuse 1.2
x² + x² = 1.2²
2x² = 1.44 ( divide both sides by 2 )
x² = 0.72 ( take square root of both sides )
x =
≈ 0.85 m ( to 2 dec. places )
the ends are 0.85 m = 85 cm from the top of the pole

Answer:
x = 7 cm
Step-by-step explanation:
The two triangles are similar so ...
x/(6 cm) = (42 cm)/(36 cm)
Multiplying by 6 cm, you get ...
x = (6 cm)(42 cm)/(36 cm) = (6 cm)(7/6)
x = 7 cm
