Quinn leaves her house at 10:00 am and runs 3 miles at a steady pace of 6 miles per

Mathematics
1 answer:
bogdanovich [222]3 years ago
8 0

Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.

Velocity is <u>distance divided by time</u>, that is:

v = \frac{d}{t}

  • She walked <u>3 miles</u> at a velocity of <u>6 miles per hour</u>, thus d = 3, v = 6. The time is:

v = \frac{d}{t}

t = \frac{d}{v} = \frac{3}{6} = 0.5

  • Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.
  • Distance of <u>3 miles,</u> velocity of <u>2 miles per hour,</u> thus d = 3, v = 2. The time she took to return, in hours, is:

t = \frac{d}{v} = \frac{3}{2} = 1.5

1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

HELP ASPAP!!!!! WILL MARK BRAINIEST standard deviation
Umnica [9.8K]

Answer:

The standard deviation of the given data is 11.34.

Step-by-step explanation:

We have to find the standard deviation for the given data;

Grade on     No. of students          

 test (X)        with that score (f)        X \times f       ( X - \bar X)^{2}        f \times ( X - \bar X)^{2}

     50                  1                       50      1073.218      1073.2176

     57                 2                       114      663.578      1327.1552

     60                 4                       240       518.018     2072.0704

     65                 3                       195       315.418      946.2528

     72                 3                       216        115.778       347.3328

     75                12                       900        60.218       722.6112

     77                10                       770        33.178       331.776

     81                 6                       486        3.098       18.5856

     83                 6                       498        0.058        0.3456

     88                9                       792        27.458      247.1184

     90                12                      1080        52.418      629.0112

     92                12                       1104        85.378     1024.5312

     95                 2                        190        149.818      299.6352

     99                 4                        396        263.738     1054.9504

    100          <u>       5   </u>                 <u>    500    </u>     297.218   <u>   1486.088     </u>

   Total             <u>      91       </u>                <u>    7531     </u>                       <u>    11580.68    </u>

Firstly, the mean of the above data is given by;

            Mean, \bar X  =  \frac{\sum X \times f}{\sum f}

                             =  \frac{7531}{91}  =  82.76

Now, the standard deviation of the data is given by;

          Standard deviation, S.D.  =  \sqrt{\frac{\sum f(X-\bar X)^{2} }{\sum f-1}}

                                                     =  \sqrt{\frac{11580.68}{91-1}}

                                                     =  11.34

Hence, the standard deviation of the given data is 11.34.

What Ratio can you write that compares days with games two days without them right this ratio three ways to
Ira Lisetskai [31]

Answer:

As a fraction: \mathbf{\dfrac{363}{2}}

As a colon,  363:2

By using the word to; we have: 363 to 2

Step-by-step explanation:

A ratio is a comparison of two quantities. We can write a ratio as a fraction, using the word “to,” or using a colon.

A rate is a ratio that compares two different units, such as distance and time, or a ratio that compares two different things measured with the same unit, such as cups of water and litres of petrol.

We can use a ratio to compare the number of days regardless of employing any professional sports events each year with the total number of days in a year.

The ratio with which we can write, that compares days with games in a year with two days without them can be written in three ways.

Suppose there are 365 days in a year and it appears that two days in that year exist without a game.

i.e.

365 - 2(days without game) = 363 days with a game

Then:

As a fraction: \mathbf{\dfrac{363}{2}}

As a colon,  363:2

By using the word to; we have: 363 to 2
