Answer:

Mean=51.86

Mode=49

Median=52

Range=6

Step-by-step explanation:

We are given a data set:

49, 49, 54, 55, 52, 49, 55

We arrange this in ascending order:

49,49,49,52,54,55,55

Mean=sum of all the elements/number of elements

         =49+49+49+52+54+55+55/7

Mean  =51.86

Mode is that element of the data set which has highest frequency i.e. the element which comes most.

Hence, Mode=49

Median is the middle element of the data set arranged in ascending order.

Hence, Median=52

Range=highest element-lowest element

Hence, Range=55-49

            Range=6

Answer:

Correct answer is option D. 96.4 yd.

Step-by-step explanation:

Please refer to the attached figure for labeling of the given diagram.

ABC is a triangle with the following labeling:

A is the hole, B is the Tee and C is the point where the ball is.

Sides are labeled as:

a =255\ yd\\c = 305\ yd\\\angle B =17^\circ

To find:

Side b = ?

Solution:

Here, we have one angle and two sides . Third side of the triangle is to be found opposite to the given angle.

We can use cosine formula here to find the value of the unknown side.

cos B = \dfrac{a^{2}+c^{2}-b^{2}}{2ac}

Putting all the values:

cos 17 = \dfrac{255^{2}+305^{2}-b^{2}}{2\times 255\times 305}\\\Rightarrow 0.956 = \dfrac{65025+93025-b^{2}}{155550}\\\Rightarrow 148753.2= 158050-b^{2}\\\Rightarrow b^{2}= 158050-148753.2\\\Rightarrow b^{2}= 9296.795\\\Rightarrow b= 96.42\ yd

So, the distance between the Ball and hole is 96.42 yd

Correct answer is option D. 96.4 yd.
