According to a survey of 100 people regarding their movie attendance in the last year, 40 had seen a science fiction movie, 50 h

Anarel [89]

Answer:

Kindly check attached picture ; 37.5%

Step-by-step explanation:

Let:

S = number of science fiction movie viewers

H = number of horror movie viewers

A = number of adventure movie viewers

From the information given :

n(SnHnA) = 5

n(SnH) only = 15 - 5 = 10

n(SnA) only = 25 - 5 = 20

n(AnH) only = 5 - 5 = 0

n(S) only = 40 - (10+5+20) = 5

n(H) only = 40 - (10+5+0) = 25

n(A) only = 50 - (5 + 20 + 0) = 25

2.) % of science fiction movie to horror movie fans

Total Science fiction movie fans = n(S) = 40

Science fiction and Horror movie fans = n(SnH) = 15

[n(SnH) / n(S)] * 100%

(15 / 40) * 100%

0.375 * 100%

= 37.5%

If DEF=GJH, find each missing measure

Bas_tet [7]

Congruent triangles have equal corresponding sides and angles.

The measure of the side lengths are: $\mathbf{DF = 16m}$ , $\mathbf{JH = 14m}$ and $\mathbf{GJ = 19m}$
The measure of the angles are: $\mathbf{\angle G = 34^o}$ , $\mathbf{\angle J = 41^o}$ and $\mathbf{\angle F = 105^o}$

The given parameters are:

$\mathbf{\triangle D EF \cong \triangle GJH}$

$\mathbf{EF = 14m}$

$\mathbf{D E = 19m}$

$\mathbf{GH = 16m}$

$\mathbf{\angle D = 34^o}$

$\mathbf{\angle H = 105^o}$

$\mathbf{\triangle D EF \cong \triangle GJH}$ means that triangles DEF and GHJ are congruent triangles.

So, we have:

$\mathbf{DF = GH}$

This gives

$\mathbf{DF = 16m}$

Also, we have:

$\mathbf{JH = EF}$

This gives

$\mathbf{JH = 14m}$

Also, we have:

$\mathbf{GJ = DE}$

This gives

$\mathbf{GJ = 19m}$

The following angles are also congruent

$\mathbf{\angle F = \angle H}$

This gives

$\mathbf{\angle F = 105^o}$

Also, we have:

$\mathbf{\angle G = \angle D}$

This gives

$\mathbf{\angle G = 34^o}$

The measure of angle J is then calculated using

$\mathbf{\angle J + \angle H + \angle G = 180^o}$

This gives

$\mathbf{\angle J + 105 + 34= 180^o}$

$\mathbf{\angle J + 139= 180^o}$

Subtract 139 from both sides

$\mathbf{\angle J = 41^o}$

What is the area of this triangle?

earnstyle [38]

Answer:

depends on what type of triangle it is but generally there are two formulas area of triangle is ½ × base × height and another one is heron's formula used for finding area of triangle it is applicable only when side of a triangle is given A =

$\sqrt{s(s - a)(s - b)(s - c)}$
