6= w/8
is
w= -48
that should be if not sorry DX
N = 20, the number of questions
p = 1/5 = 0.2, the probability of making a correct guess
q = 1 - p = 0.8, the probability of making an incorrect guess.
Expected success = 60% or 6 of 10.
From the binomial distribution,
P(6 of 10) = ₁₀C₆ p⁶q⁴
= 210*0.2⁶*0.8⁴ = 0.0055
Answer: 0.0055
Answer:
32 people came in blue cars and 6 people came in red cars
Step-by-step explanation:
Technically, all 48 people came in red or blue cars, but I'm assuming that's not what the question is asking.
To find how many people came in blue cars, we do 2/3*48 which is equal to 32 people.
To find how many people came in red cars, we do 1/8*48 which is equal to 6 people.
For this graph the equation is x= -3
Because in the coordinates you gave, all the x values are -3 telling me that the line is a straight vertical line passing through the -3 x-axis and has no y-intercept as it's a vertical line, not diagonal, so it's not passing through the y-axis. Plus because of this too this line has no gradient.
Answer: pi
Step-by-step explanation:
Formula for circumference = 2 x pi x radius
Formula for diameter = 2 x radius
Plug in 6.25 for radius
Circumference = 2 x pi x 6.25
Diameter = 2 x 6.25
Find ratio by diving Circumference over Diameter:
(2 x pi x 6.25) / (2 x 6.25)
Simplify: answer is pi
could also be 3.14
