The probability that one person chosen has blue eyes is 0.57.

The given parameters:

  • <em>Number of females, = 60 </em>
  • <em>Number of males, = 70</em>
  • <em>Probability of choosing a female with blue eyes, = 0.41</em>
  • <em>Probability of choosing a male with blue eyes, = 0.7</em>

The total number of female and male with blue eyes is calculated as;

Total female with blue eyes = 0.41 x 60 = 24.6

Total male with blue eyes = 0.7 x 70 = 49

Total blue eyes = 24.6 + 49 = 73.6

The probability that one person chosen has blue eyes is calculated as follows;

P = \frac{73.6}{60 + 70}\\\\P = \frac{73.6}{130}  \\\\P = 0.566\\\\P \approx 0.57

Thus, the probability that one person chosen has blue eyes is 0.57.

The first gardener can finish the job in 6 hours, and the second gardener can do the same job in 7 hours. How long it will take
marissa [1.9K]

If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.

By the same logic, the second gardener completes 1/7 of the job per hour.

So, if they work together, they complete

\dfrac{1}{6}+\dfrac{1}{7}=\dfrac{7+6}{42}=\dfrac{13}{42}

of the job per hour.

So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is

\dfrac{42}{13}\cdot 60 \approx 194

So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.

A teacher is making a history test composed of the same number of multiple-choice questions as short-answer questions. She estim
STALIN [3.7K]

Answer:

The inequality is 5.5n \leq 45

Step-by-step explanation:

Total time:

The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.

In this question:

Same number(n) of both.

Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

T = 2n + 3.5n = 5.5n

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?

This means that:

T \leq 45

So

5.5n \leq 45

The inequality is 5.5n \leq 45

The different ways that they can vote is given as 16 different ways.

<h3>How to calculate the ways that they can vote</h3>

The question say that there are a total of 4 members of the board. Out of these 4, we have the choices as yes or a no.

This tells us that each person only has 2 choices of what they want.

Hence given that the board members ar 4, we would have 2⁴

= 2 * 2 * 2 * 2

= 16

Hence the different ways that they can all vote is 16.
