M5 is the same as m1 so it's 75°
Answer:
0.13093
Step-by-step explanation:
Give. That :
Population mean = 40% = 0.4
Sample size (n) = 64
Probability that more than 30 have computer at home
Mean = np = 64 * 0.4 = 25.6
Standard deviation = sqrt(n*p*(1-p)) = 3.919
P(x > 30)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (30 - 25.6) / 3.919 = 1.1227353
p(Z < 1.122) = 0.13093 ( Z probability calculator)
The correct proportion is 16/36=12/27
Answer:
Explanation:
<u>1) Data:</u>
a) height of the person = opposite-leg to the angle the sun makes with the ground = 5 ft
b) length of the shadow = adjacent-leg to the angle the sun makes with the ground = 12 ft
c) angle, α = ?
<u>2) Solution</u>
- tanα = opposite-leg / adjacent-leg
- tanα = 5 ft / 12 5t = 5/12
- 22.6° rounded to the nearest degree is 23° ← answer
