g100num [7]

Answer:

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.

Step-by-step explanation:

The formula for the probability of an exponential distribution is:

P(x < b) = 1 - e^(b/3)

Using the complement rule, we can determine the probability of a customer having to wait more than 10 minutes, by:

p = P(x > 10)

  = 1 - P(x < 10)

  = 1 - (1 - e^(-10/10) )

  = e⁻¹

  = 0.3679

The z-score is the difference in sample size and the population mean, divided by the standard deviation:

z = (p' - p) / √[p(1 - p) / n]

  = (0.5 - 0.3679) / √[0.3679(1 - 0.3679) / 100)]

  = 2.7393

Therefore, using the probability table, you find that the corresponding probability is:

P(p' ≥ 0.5) = P(z > 2.7393)

<em>P(p' ≥ 0.5) = 0.0031</em>

<em></em>

Therefore,  the probability that at least half of them need to wait more than 10 minutes is <em>0.0031</em>.

18 Given: the sequence 4, 7, 10, 13,...
Sergio039 [100]

a₁ = 4

n = 10

d = 3

a = a₁ + (n - 1)d

a₁₀ = 4 + (10 - 1)3

a₁₀ = 4 + (9)3

a₁₀ = 4 + 27

a₁₀ = 31

The 10th term would be 31 and the d variable will be replaced with the number 3.

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
OleMash [197]

Answer:

Hello! answer: area is 6 cm2

Step-by-step explanation:

Triangle area formula: base × height ÷ 2 or base × height × 1/2 so...

12 × 16 = 192 192 ÷ 2 = 96

12 ÷ 4 = 3

16 ÷ 4 = 4

3 × 4 = 12 12 ÷ 2 = 6 therefore the area is 6 hope that helps!

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many more girls than boys are there?
lisov135 [29]

Answer:

5

Step-by-step explanation:

sum the parts of the ratio, 3 + 4 = 7 parts

Divide the number of students by 7 to find the value of one part of the ratio

35 ÷ 7 = 5 ← value of 1 part of the ratio, then

3 parts  3 × 5 = 15 ← number of boys

4 parts = 4 × 5 = 20 ← number of girls

20 - 15 = 5

There are 5 more girls than boys
