A university knows from historical data that 25% of students in an introductory statistics class withdraw before completing the
Vikki [24]

Answer:

13.4%

Step-by-step explanation:

Use binomial probability:

P = nCr p^r q^(n-r)

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1-p).

Here, n = 16, r = 2, p = 0.25, and q = 0.75.

P = ₁₆C₂ (0.25)² (0.75)¹⁶⁻²

P = 120 (0.25)² (0.75)¹⁴

P = 0.134

There is a 13.4% probability that exactly 2 students will withdraw.

Solve for x. M=5/dx+e
snow_lady [41]

After solving  M=\frac{5}{dx}+e we get value of x:  x=\frac{5}{(M-e)d}

Step-by-step explanation:

We need to solve the equation M=\frac{5}{dx}+e to find value of x

Solving

M=\frac{5}{dx}+e

Adding -e on both sides

M-e=\frac{5}{dx}+e-e

M-e=\frac{5}{dx}

Multiply both sides by dx

dx(M-e)=5

Divide both sides by M-e

dx=\frac{5}{M-e}

Divide both sides by d

x=\frac{5}{(M-e)d}

So, After solving  M=\frac{5}{dx}+e we get value of x:  x=\frac{5}{(M-e)d}
