Answer:

13 1/8

Step-by-step explanation:

We need to change the mixed number 5 1/4 to an improper fraction

5 1/4 = (4*5+1)/4 = 21/4

5 1/4 ÷ 2/5

21/4 ÷ 2/5

Copy dot flip

21/4 * 5/2

105 / 8

We need to change this back to a mixed number

8 goes into 105  13 times  (13*8 =104)  with 1 left over

13 1/8

posledela

Answer:

a. 0.2639 or 26.39%

b. 0.6242 or 62.42%

Step-by-step explanation:

This problem can be treated as a binomial model with probability of success p = proportion of defectives in the batch.

Number of trials (n) = 10.

For any number of successes 'k', the probability is:

P(X=k) = \frac{n!}{(n-k)!k!}*p^k*(1-p)^{n-k}

a. If p =0.10, what is P(x >1):

P(X>1) = 1- P(X=0)-P(X=1)\\P(X>1) =1- \frac{10!}{(10-0)!0!}*0.10^0*(1-0.10)^{10-0}- \frac{10!}{(10-1)!1!}*0.10^1*(1-0.10)^{10-1}\\P(X>1) = 1-0.348678-0.287420\\P(X>1) =0.2639

The probability is 0.2639 or 26.39%.

b. If p =0.20, what is P(x >1):

P(X>1) = 1- P(X=0)-P(X=1)\\P(X>1) =1- \frac{10!}{(10-0)!0!}*0.20^0*(1-0.20)^{10-0}- \frac{10!}{(10-1)!1!}*0.20^1*(1-0.20)^{10-1}\\P(X>1) = 1-0.107374-0.268435\\P(X>1) =0.6242

The probability is 0.6242 or 62.42%.

Definition qualitative graph
kirza4 [7]

Answer:

Qualitative data is information about qualities; information that can't actually be measured.  Some other aspects to consider about qualitative data:

  • Represented through pictures that explore the data in a visual way
  • Visual representations focus on the themes found in the data
  • Can tell a story
  • Can also be displayed graphically as a pie chart or bar graph, the same as quantitative data, however, this can be tricky and can be done incorrectly easily

At Dizzy World theme park, Vera waited in line for 35 minutes and rode on a Magical Mushroom for 7 minutes. What is the percent
IgorLugansk [536]

Answer: the percent value-added time for this ride is 16.67%

Step-by-step explanation:

 Given that;

Waiting time for Vera = 35 minutes

Length of Vera's ride = 7 minutes

total processed time will; ( 35 + 7 ) = 42 minutes

the percent value-added time for this ride = ?

so

Percentage value-added time of Vera will be

= (length of the ride / total process time) × 100

we substitute

⇒ (7 / 42) × 100

⇒ 0.16666 × 100

⇒ 16.67%

Therefore the percent value-added time for this ride is 16.67%
