You can measure the width of the lake using a surveying technique, as
shown in the diagram. Find the width of the lake, WX.
Justify your answer.

78

Step-by-step explanation:

Remark

There are two similar triangles in the diagram: ΔYZX and  ΔVWX.

That being true a ratio can be set up as

VW / ZY = WX / XZ

Givens

VW = 104

ZY = 8

WX = ?

XZ = 6

Solution

104 / 8 = WX / 6

104 * 6 / 8 = WX

WX = 78

So the width of the lake is 78 meters

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
