The contestant must answer at least 33 questions correctly in order to end up with over 350 total points. The 100 they start off with means that they should really only have to answer 25 questions correctly, but this is not the case. 33 x 10 = 330, plus the first 100 = 430. This is necessary as a buffer, seeing as how if they get every question other than the necessary 33 wrong, it will be a reduction of 68 points total (17 incorrect, which is minus 4 = 68)
(430 - 68 = 362). I hope this was thoroughly explained and broken down! Best of luck!!
Answer:
measure of 1 = 117 degrees
measure of 2 = 63 degrees
<em>*x = 39</em>
Step-by-step explanation:
m1 = 3 x 39 = 117
m2 = 39 + 24 = 63
117 + 63 = 180 degrees
Answer:
The probability of success is .12
The probability of failure is .88
According to the binomial theorem the probability of 3 success is
10! / (3! * 7!) * .12^3 * .88^7 = .085
Answer:
y = -3x - 2
Step-by-step explanation:
Equation of a line passing through 
and slope m is,
Slope of a line passing through and 
is,
Slope = 
Slope of the line passing through (0, -2) and (1, -5) will be,
Slope = 
m = - 3
Therefore, equation of the line passing through (0, -2) and slope = -3 will be,
y + 2 = -3(x - 0)
y + 2 = -3x
y = -3x - 2
