Pretty easy my friend, consider the two numbers we want x and y

x + y = 94
x - y = 12

Now you solve the system

x = 94 - y
94 - y - y = 12

x = 94 - y
94 - 2y = 12

x = 94 - y
- 2y = 12 - 94

x = 94 - y
- 2y = - 82

x = 94 - y
2y = 82

x = 94 - y
y = 41

x = 94 - 41
y = 41

x = 53
y = 41

Lets denote the numbers x and y:

The sum of two numbers 94 → x + y = 94

Their difference is 12 → x - y = 12

We have:

x + y = 94

x - y = 12

----------------  Add both equations

2x = 106

x = 106/2

x = 53

Using first equation:

x + y = 94

53 + y = 94

y = 94 - 53

y = 41

A/ The numbers are 53 and 41.

The lines of symmetry in a regular polygon are equal to the number of sides minus 2. True or False
galina1969 [7]

Answer:

False

Step-by-step explanation:

A regular polygon may be defined as the polygon that have sides of equal length known as equilateral and angles made up of equal angles, known as equiangular.

The $\text{number of lines}$ of symmetry in a regular polygon is always equal to the number of sides of the polygon. For example, a regular pentagon have 5 sides, so the lines of symmetry of the regular pentagon is also 5, a square having 4 sides also has 4 lines of symmetry.

zhenek [66]

Answer:

test statistic is ≈ -0.36

p-value is  ≈ 0.64

There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.

Step-by-step explanation:

a hypothesis test where H_0: mu = 235 and H_1:mu > 235

test statistic can be calculated as follows:

z=\frac{X-M}{\frac{s}{\sqrt{N} } } where

  • sample mean driving distance (233.8 yards)
  • M is the average expected distance that the average golfer can hit the ball under null hypothesis. (235 yards)
  • s is the standard deviation (46.6 yards)
  • N is the sample size (192)

Then test statistic is z=\frac{233.8-235}{\frac{46.6}{\sqrt{192} } } =-0.3568

p-value is  0.64 >0.05

There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
