According to the information provided the statement of both people is incorrect (option D)

Ahmad's statement is false because he claims that in the situation where 1000 people spend $ 1000 on lottery tickets they would get back $ 5000. However, the recovery would be $ 500 This statement can be verified by doing the following operation:

0.50 x 1000 = 500

On the other hand, Juana's statement is false because she says that people who buy a lottery ticket have a probability of winning of 0.50 on average. However, the true probability is 0.02. This statement can be checked by doing the following operation:

1 ÷ 50 = 0.02

According to the above, none of the statements of the characters is true.

(05.05) On a coordinate plane the coordinates of vertices R and T for a polygon are R(-7, 3) and T(3,3). What is the length of S

Talja [164]

Answer:

c) 10 units

The length of side RT of the polygon RT = 10

Step-by-step explanation:

Given the coordinates of vertices R and T

R( -7 ,3) and T (3 ,3)

we have to find the length of side RT

We will use distance formula

RT = $\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }$

RT $= \sqrt{(3-3)^{2} +(3-(-7))^{2} }$

$RT = \sqrt{0+(10)^{2} }$

RT = √100

RT = 10

The length of side RT of the polygon RT = 10

Jessie designed a sculpture that is shaped like a circle. The circumference of the sculpture is 10π meters. Which measurement is

BlackZzzverrR [31]

Answer:

25πm²

Step-by-step explanation:

Circumference of the circular sculpture = πd

d is the diameter

Given

Circumference = 10π metres

Substitute into the formula

10π = πd

10 = d

d = 10m

Area of the sculpture = πd²/4

area of the sculpture = π(10)²/4

area of the sculpture = 100π/4

area of the sculpture = 25π m²

Hence the measurement closest to the area of the sculpture in square meters is 25πm²

Find an equation of the circle that has center (6, 2) and passes through (-2,-6).

Irina18 [472]

Answer:

(x - 6)² + (y - 2)² = 128

Step-by-step explanation:

Given as the circle has center ( 6 , 2)

and it passes through points (-2 , -6)

Now , standard equation of circle is (x -a)² + (y- b)² = r² , where (a , b) is center and r is the radius .

Again from given center the circle equation is

(x- 6)² + (y- 2)² = r²

Now this circle passes through points (-2 , -6)

so, (-2 -6)² + (-6 -2)² = r²

so, 8² + 8² = r²

Or, 128 = r²

i.e Radius pf this circle = 8 $\sqrt{2}$

Hence the circle equation formed is

(x- 6)² +( y-2)² = 128 Answer
