Answer:

98.0 > 97.7

Step-by-step explanation:

">" Means greater than

"<" Means less than

Two other comparison symbols are ≥ (greater than or equal to) and ≤ (less than or equal to).

Since 98.0 is greater than 97.7, you use the greater than symbol >.

1. The ratio of the measures of the sides of a triangle is 5:6:8, and

julsineya [31]

Answer:

42mm

Step-by-step explanation:

Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.

5x+6x+8x = 159.6

19x = 159.6

x = 159.6 ÷ 19

x = 8.4

Shortest side of triangle (5x) = 8.4 × 5

= 42

2. Alicia is writing the program for a video game. For one part of the game she uses the rule (x,y) ->(x-3,y+4) to move point

Taya2010 [7]

Given rule (x,y) ->(x-3,y+4) to move points on the screen.

a) We are given first input (-6,0).

(-6,0) represents x=-6 and y=0.

Plugging values of x and y in given rule (x,y) ->(x-3,y+4), we get

(-6,0) --> (-6-3, 0+4). It would give us (-9,4)

So, first output is (-9,4).

b) We are given second input (3,-4).

(-6,0) represents x=3 and y=-4.

Plugging values of x and y in given rule (x,y) ->(x-3,y+4), we get

(-6,0) --> (3-3, -4+4). It would give us (0,0).

So, second output is (0,0).

In the diagram, ABC is an equilateral triangle, BCFG is a square and CDEF is a rectangle. The perimeter of the whole diagram is

nikklg [1K]

Answer:

22 cm

Step-by-step explanation:

the perimeter = AB+BG+GF+FE+ED+DC+CA

= 65 cm

7+7+7+FE+7+DC+7=65 => FE = CD

35+ 2FE = 65

2FE = 65-35

= 30

FE = 30/2 = 15

so, GE = GF + FE

= 7+15 = 22 cm

Use the two way table below to answer the question given.

GaryK [48]

Answer:

Not independent

Step-by-step explanation:

Given

See attachment for two way table

Required

Are male and favor independent?

From the table, we have:

$Male = 20+15+17$

$Male = 52$

$Favor = 20 + 18$

$Favor = 38$

$Total = 20+15+17+18+12+7$

$Total = 89$

Calculate P(Male)

$P(Male) = \frac{Male}{Total}$

$P(Male) = \frac{52}{89}$

Calculate P(Favor)

$P(Favor) = \frac{Favor}{Total}$

$P(Favor) = \frac{38}{89}$

Calculate P(Male and Favor)

$P(Male\ and\ Favor) = \frac{Male\ and\ Favor}{Total}$

$P(Male\ and\ Favor) = \frac{20}{89}$

$P(Male\ and\ Favor) = 0.2247$

The events are independent is:

$P(Male\ and\ Favor) =P(Male) * P(Favor)$

So, we have:

$P(Male\ and\ Favor) =\frac{52}{89} * \frac{38}{89}$

$P(Male\ and\ Favor) =\frac{52*38}{89*89}$

$P(Male\ and\ Favor) =\frac{1976}{7921}$

$P(Male\ and\ Favor) =0.2495$

By comparison:

$P(Male\ and\ Favor) =0.2495$ and $P(Male\ and\ Favor) = 0.2247$ are not equal

<em>Hence, the events are not independent</em>
