Answer:

8

Step-by-step explanation:

divide 14 by 7 to get 2. IT is 2 tests a week so multipy 7 by 2 to get 14 then just add 2 to get 16. you added two meaning you added a week because each week is two tests so the answer will be 8 weeks.

Tim have to attend a total of 8 weeks this quarter before he will have taken a total of 16 quizzes.

<h3>What is unitary mehtod?</h3>

The unitary method is a process for solving a problem by first finding the value of a unit, and then finding the necessary value by multiplying the single unit value.

<h3>How to calculate how many weeks of school will Tim have to attend?</h3>

According to the problem,

Tim took 14 quizzes over the course of 7 weeks.

∴ Tim can take 1 quiz over the course of \frac{7}{14} weeks

Tim can take 16 quizzes over the course of (\frac{7}{14}) x 16 weeks = 8 weeks

∴ Tim can take 16 quizzes over the course of 8 weeks.

If you rent a car for one day and drive it for 100 miles, the cost is $40.00. If you drive it 220 miles, the cost is $46.00. Use
Gelneren [198K]
The function f(x) = (6/120) x + 40
= 0.05x + 40 where x is the excess mileage over 100

If we drive it for 300 miles x will be 300-100 = 200

so cost will be 0.05*200 + 40
= 10+40 = $50 answer

The scores of fourth grade students on a mathematics achievement test follow a normal distribution with a mean of 75 and standar
mamaluj [8]

Answer:

The appropriate solution is:

(a) 0.1056

(b) 0

(c) 0.9544

Step-by-step explanation:

The given values are:

Mean,

\mu = 75

Standard deviation,

\sigma = 4

(a)

⇒  P(x>80)=1-(x

                     =1-P[\frac{x-\mu}{\sigma}

                     =1-P[\frac{x-\mu}{\sigma}

                     =1-P(z

By using the table, we get

                     =1-0.8944

                     =0.1056

(b)

According to the question, the values are:

n = 64

\mu_\bar{x} = 75

Now,

⇒  \sigma_\bar{x} = \frac{\sigma}{\sqrt{n} }

         = \frac{4}{\sqrt{64} }

         = \frac{4}{8}

         = 0.5

⇒  P(\bar {x} >80 ) = 1 - P(\bar x

                      =1 - P[\frac{(\bar x-\mu_\bar x)}{\sigma \bar x} < \frac{80-75}{0.5}  ]

                      =1-P(z

By using the table, we get

                      =1-1

                      =0

(c)

As we know,

⇒ \sigma_\bar x = \frac{\sigma}{\sqrt{n} }

        = \frac{4}{\sqrt{64} }

        = \frac{4}{8}

        = 0.5

then,

= P(74< \bar x

= P[\frac{74-75}{0.5} < \frac{\bar x-\mu \bar x}{\sigma \bar x} < \frac{76-75}{0.5} ]

= P(-2

= P(z

By using the table, we get

= 0.9772-0.0228

= 0.9544

Answer:

19.82%

Step-by-step explanation:

Add all members that want weight lifting

47 + 21 + 14 + 29 = 111

111 / total members

111 / 560 = 0.1982

0.1982 * 100% = 19.82%

12. Make a box-and-whisker plot of the data. (1 point)
Sophie [7]

The box-and-whisker plot of the data, showing the five-number summary, is shown in the image atatched below.

<h3>What is the Box-and-whisker Plot?</h3>

The box-and-whisker plot is a plot that displays the minimum, maximum, median, lower and upper quartile of a data, which is termed as the five-number summary of a data.

Given the data, 20, 23, 28, 14, 13, 24, 18, 11, find the five-number summary:

  • Minimum - 11
  • Lower Quartile - 13.5
  • Median - 19
  • Upper Qaurtile - 23.5
  • Maximum - 28

Therefore, the box-and-whisker plot of the data, showing the five-number summary, is shown in the image atatched below.
