Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

s = 2.07

The mean and standard deviation for the year 2018 scores is:

                                     2018

Mean                                 76

Standard deviation       2.07

The mean for 2019 scores is:

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

The standard deviation for 2019 scores is:

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

Scores turned in by an amateur golfer at the, №17887889, 03.11.2021 07:31

s = 5.26

The mean and standard deviation for the year 2019 scores is:

                                     2019

Mean                                 76

Standard deviation       5.26

Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.

Thus, the variation in scores was higher in 2019.

Step-by-step explanation:

The mean for 2018 scores is:

M ean ( \overline X) = \dfrac{\sum x_i}{n}

M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}

M ean ( \overline X) = \dfrac{608} {8}

\mathbf{M ean ( \overline X) = 76}

The standard deviation for 2018 scores is:

s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1}  }

s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1}  }

s = \sqrt{\dfrac{30}{7}  }

s = 2.07

The mean and standard deviation for the year 2018 scores is:

                                     2018

Mean                                 76

Standard deviation       2.07

The mean for 2019 scores is:

M ean ( \overline X) = \dfrac{\sum x_i}{n}

M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}

M ean ( \overline X) = \dfrac{608} {8}

\mathbf{M ean ( \overline X) = 76}

The standard deviation for 2019 scores is:

s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1}  }

s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1}  }

s = \sqrt{\dfrac{194}{7} }

s = 5.26

The mean and standard deviation for the year 2019 scores is:

                                     2019

Mean                                 76

Standard deviation       5.26

Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.

Thus, the variation in scores was higher in 2019.

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
