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:
1) A = -10, B = -4, distance = 6 units
2) Eqaution: 3(x+4) = 60
Tyler's age: 16 Samantha: 20
3) x < 1
Draw a number line from 1 towards left, with an open circle at x = 0
Step-by-step explanation:
1) A/2 = -5
A = -5×2 = -10
8 = -B/0.5
8×0.5 = -B
B = -4
Distance = -4 - (-10) = -4 + 10 = 6
2) S = 4 + x
3s = 60
3(4 + x) = 60
3S = 60 S = 20
4 + x = 20 x = 16
3) x/2 + ¼ < ¾
x/2 < ¾ - ¼
x/2 < ½
x < 1
Draw a number line going towards left from 1, with an open circle at x=1 because x=1 is not included
Answer:
yes the correct answer is what you chose
Step-by-step explanation:
the left side 4 is less than the right side 6
Answer:
Step-by-step explanation:
Neither blue plot line is dashed, so we eliminate any equation that contains the symbols "<" or ">". Remove A and C
B and D (actually all options) have y ≤ -x + 4 which is a line with slope -1 any y intercept 4. This represents the area below the line running from (0, 4) to (4, 0)
Which leaves us to select from y ≥ x + 2 for option B or y ≤ x + 2 for option D
As the shaded area is <em>below</em> the line we choose <u>option D</u>
