Answer:
A.The probability that exactly six of Nate's dates are women who prefer surgeons is 0.183.
B. The probability that at least 10 of Nate's dates are women who prefer surgeons is 0.0713.
C. The expected value of X is 6.75, and the standard deviation of X is 2.17.
Step-by-step explanation:
The appropiate distribution to us in this model is the binomial distribution, as there is a sample size of n=25 "trials" with probability p=0.25 of success.
With these parameters, the probability that exactly k dates are women who prefer surgeons can be calculated as:
A. P(x=6)
B. P(x≥10)
C. The expected value (mean) and standard deviation of this binomial distribution can be calculated as:
Let's solve your equation step-by-step.
−3x2−4x−4=0
Step 1: Use quadratic formula with a=-3, b=-4, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−4)±√(−4)2−4(−3)(−4)
2(−3)
x=
4±√−32
−6

Answer:
4x+7*500=11300 is the formula. (there are many formulas this might not be correct) (x is the number of students)
1925 students
Step-by-step explanation:

AN ASSESMANT?!?!?!?
500*7=$3500 for the adults
11,200-3500=7700
so 7700/4=1925

Answer:
The number b is bigger than the number a by of a.
Step-by-step explanation:
1. If the number a is smaller than the number b by 1/5 of b, then
Thus,
2. Consider the expression
This gives you that the number b is bigger than the number a by of a.
