Step-by-step explanation:
<h3>(1)</h3>
The probability of landing on the color gray ONCE
= 2/7
Since it is spun 35 times, the expected number of times that it lands on a gray will be
(2/7 × 35) = 10 times
<h3>(2)</h3>
The probability of landing on the color black ONCE
= 1/7
Since it is spun 105 times, the expected number of times that it lands on a black will be
(⅐ × 105) = 15 times
The formula is:
Expected value = (Number of spinning)×(probability of landing on a colour)
M and n are parallel
so 3x -14 = 2x +25
3x - 2x = 25 + 14
x = 39
<span>the value of x = 39 will make both these angles equal.
3(39) -14 = 117 - 14= 103
2(39) + 25 = 78 + 25 = 103
Answer x = 39</span>
The answer should be around
y’=1/5 + 1/5 x In(x)
In fraction, it would be:
