One golfer's scores for the season are 88, 90, 86, 89, 96, and 85. Another

Allisa [31]

Mean of the first golfer = 89

Mean of the second golfer = 87

Range of the first golfer = 11

Range of the second golfer = 8

Explanation:

First golfer scores 88, 90, 86, 89, 96 and 85.

Sum of the scores of first golfer = 88 + 90 + 86 + 89 + 96 + 85 = 534

Number of observation of first golfer = 6

$\text {Mean} = \frac{\text {Sum of the observation}}{\text {Number of observation}}$

Mean of the first golfer = $\frac{534}{6}=89$

Mean of the first golfer = 89

Range of the first golfer = Highest score – Lowest score

= 96 – 85

Range of the first golfer = 11

Second golfer scores 91, 86, 88, 84, 90 and 83.

Sum of the scores of second golfer = 91 + 86 + 88 + 84 + 90 + 83 = 522

Number of observation of second golfer = 6

$\text {Mean} = \frac{\text {Sum of the observation}}{\text {Number of observation}}$

Mean of the second golfer = $\frac{522}{6}=87$

Mean of the second golfer = 87

Range of the second golfer = Highest score – Lowest score

= 91 – 83

Range of the second golfer = 8

Comparing the golfer's skills:

Mean of first golfer is greater than Mean of second golfer. (i.e. 89 > 87)

Range of first golfer is greater than Range of second golfer. (i.e. 11 > 8)

Thus, first golfer have more skills than second golfer.

Solve the following multiplication and division problems.

algol13

Answer:

a. 22.5 km

b. 267.52 m

c. 95 m

d. $(4.2)(10^{-5})$ km

Step-by-step explanation:

a. You can convert from hectometers to kilometers, and then you can make the multiplication:

$\frac{5hm}{10}=0.5km$

$(3km)(0.5km)(15)=22.5km$

b. You can convert from centimeters to meters, and then you can make the multiplication:

$\frac{44cm}{100}=0.44m\\(19m)(0.44m)(32)=267.52m$

c. You only need to divide 1,140 meters by 12:

$\frac{1,140m}{12})=95m$

d. You can convert from hectometers to kilometers, from decameters to kilometers and from meters to kilometers, and divide this by 15:

$\frac{6hm}{10}=0.6km$

$\frac{7dam}{100}=0.07km$

$\frac{5m}{1000}=0.005km$

$\frac{(3km)(0.6km)(0.07km)(0.005km)}{15}=(4.2)(10^{-5})$ km
