Answer:

Step-by-step explanation:

We would apply the formula for binomial distribution. It is expressed as

P(x = r) = nCr × q^(n - r) × p^r

Where

n = number of samples

p = probability of success.

q = probability of failure

From the information given,

n = 12

p = 90% = 90/100 = 0.9

q = 1 - p = 1 - 0.9 = 0.1

28) Probability that at least 10 are ripe within 4 days is expressed as

P(x ≥ 10) = P(x = 10) + P(x = 11) + P(x = 12)

P(x = 10) = 12C10 × 0.1^(12 - 10) × 0.9^10 = 0.23

P(x = 11) = 12C11 × 0.1^(12 - 11) × 0.9^11 = 0.38

P(x = 12) = 12C12 × 0.1^(12 - 12) × 0.9^12 = 0.28

P(x ≥ 10) = 0.23 + 0.38 + 0.28 = 0.89

29) Probability that no more than 9 are ripe within 4 days is expressed as

P(x ≤ 9) = 1 - P(x ≥ 10)

P(x ≤ 9) = 1 - 0.89 = 0.11

Diano4ka-milaya [45]
So, if it grows by 6.75%, each year the population is 106.75% of the year before.

After 1 year, 370,000(1.0675). After two years, 370,000(1.0675)(1.0675).

370,000(1.0675)12 = your answer

Simplify 3^5/3^2.<br> I do have a basic understanding but I need help on this.
ahrayia [7]
The answer is:  " 27 " .
__________________________________________

3⁵ / 3² = 3⁽⁵⁻²⁾ = 3³ = 3 * 3 * 3 = 9 * 3 = 27 .
__________________________________________
-Edit -- Note the following property of exponents :  "quotient rule" of exponents:
_____________________________________________
Given that "a" and "b" are positive integers; and that "x" is a real number greater than "zero"; 
____________________________________________
  If a <span>≥ b ,  then:

   x</span>ᵃ /xᵇ = x⁽ᵃ ⁻ ᵇ⁾ ;
____________________________________________
If a <span>< b , then:
</span>
xᵃ /xᵇ = x⁽ᵇ ⁻ ᵃ⁾

The cost for x number of students to attend an after school sporting event can be represented bu the functon C(x). If C(124) = 5
lara [203]
Alright! Given that C(x) is Cost(Students) = 558, we can eliminate:

2. 558 students paid to attend the event.
5. The event generated $124 from student revenue.

Now, in order to find the cost per student we simply divide 124 on both sides:

\frac{C(124)}{124} =  \frac{558}{124}

124 cancels on the left and 558/124 is 4.5 or $4.50. 

Since we just determined the cost of one student, we can eliminate 3.

To check if 124 students paid, we simply add the cost to the equation and check:

4.5(124) = 558

558 = 558 √

It checks out, so we determined that both 1 and 4 are correct.
