Answer:
1/6 x 1/6
Step-by-step explanation:
Chance of getting 4 heads in a row is (1/2)^4=1/16. So it should take 16 tries to likely get 4 heads in a row. Now to find amount of coin tosses it would be 16 x 4 = 64 coin tosses.

Answer:
3x +4y = -8
Step-by-step explanation:
The perpendicular line will have the x- and y-coefficients swapped, and one of them negated. The constant in the equation will be such that the given point values will satisfy the equation.
4x -3y = 18 . . . . . . given equation
3x +4y = 3(8) +4(-8) = -8 . . . . swap coefficients, used point coordinates
3x +4y = -8 . . . . . the equation of the line you want

Answer:
a) 0.923
b) 0.957
c) 0.88
d) 0.077
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 40
Standard Deviation, σ = 14
We are given that the distribution of number of milligrams of porphyritic per deciliter of blood is a bell shaped distribution that is a normal distribution.
Formula:
a) P(xis less than 60)
P(x < 60)
Calculation the value from standard normal z table, we have,
b) P(x is greater than 16)
Calculating the value from the standard normal table we have,
c)P(x is between 16 and 60)
d) P(x is more than 60)
P(x > 60) = 1 - P(x < 60) = 1 - 0.923 = 0.077
