Answer:

Option D is correct

Step-by-step explanation:

From the question, we have:

[tex]Sack\ 1: B, W[/tex]

[tex]Sack\ 2: G, Y[/tex]

[tex]Sack\ 3: S, R[/tex]

Required

The tree diagram

The selection process is as follows:

[tex]Sack\ 1: B, W[/tex]

[tex]Sack\ 1\ and\ Sack\ 2: B (G,Y); W(G,Y)[/tex] -- i.e. we write sack 2 as a subset of 1

[tex]Sack\ 1, 2\ and\ 3: B (G(S,R),Y(S,R)); W(G(S,R),Y(S,R))[/tex] -- i.e. we write sack 3 as a subset of 2

The only tree diagram that illustrates this is: option D

Answer:

um u gotta give numbers how r we gonna answer?

Step-by-step explanation:

Answer:

C. 27.5

Step-by-step explanation:

since 24 and 31 are one standard deviation below or above the mean, we could subtract the two values and divide them by two to help find the mean.

we would first subtract the two values

31-24 = 7

we would then divide that number by 2 since we are finding the average between the two numbers

7/2 = 3.5

using the 3.5, you add it to the lower value (24) and subtract it from the higher value (31)

24+3.5 = 27.5

31-3.5 = 27.5

since both calculated numbers were equal, we know that we calculated the mean correctly.

Answer:

h=1/2Ab

Step-by-step explanation:

========================================================

Work Shown:

The tangent ratio involves the opposite over adjacent.

tan(angle) = opposite/adjacent

tan(A) = BC/AC

tan(A) = sqrt(75)/5

tan(A) = ( 5*sqrt(3) )/5 .... see the section below

tan(A) = sqrt(3)

---------------------------

sqrt(75) = sqrt(25*3)

sqrt(75) = sqrt(25)*sqrt(3)

sqrt(75) = 5*sqrt(3)

Answer:

1.2r

Step-by-step explanation:

The arc length in terms of r will be equal to 1.2r.

The distance between two places along a segment of a curve is known as the arc length. Curve rectification is the process of measuring the length of an irregular arc section by simulating it with connected line segments.

It is given that the angle in radians is 1.2 and the radius is r then the arc length will be calculated as below:-

The arc length = Angle x radius

The arc length  = 1.2 x r

The arc length  = 1.2r

Therefore, the arc length in terms of r will be equal to 1.2r.

Answer:

129.89 m²

Step-by-step explanation:

Area of a circle of radius r is A = πr².

If r = 6.43 m, then A = π(6.43 m)²  =  129.89 m²

Answer:

T = (m × 20) + 25

(2.5 × 20) + 25 = 75

Answer:

Option 4

Step-by-step explanation:

"Angle formed between a secant and a tangent at a point outside a circle is equal to half of the difference of the measure of the intercepted arcs"

By applying this theorem in the figure given in the picture,

m∠RST = [tex]\frac{1}{2}[\text{m(arc TU - m(arc RT))}][/tex]

[tex]x=\frac{1}{2}(155-65)[/tex]

[tex]x=\frac{1}{2}(90^0)[/tex]

[tex]x=45^0[/tex]

Therefore, Option 4 is the correct option.

Answer:

x = 46, y = 67

Step-by-step explanation:

x = ∠ AEC = 46 ( alternate angles )

Since Δ ACE is isosceles then the base angles are congruent, then

y = [tex]\frac{180-46}{2}[/tex] = [tex]\frac{134}{2}[/tex] = 67

Answer:

x=46° and y=67°

Step-by-step explanation:

triangle ACE is isosceles, meaning <A=<B=y

any triangle is add up to 180. <A+<B+<C=180

y+y+46=180

2y=180-46

2y=134

divide both sides by 2

y=134/2

y=67°

for angle x°

since AB is parallel to CD,hence

<AEC=<ECD

x=46°

Answer:

$52.08

Step-by-step explanation:

There are 12 months in a year, so 3 years will have 36 months.

Find how much money she has to save in total:

6375 - 4500

= 1875

Divide this by 36 to find how much she has to save each month:

1875/36

= $52.08

So, she will have to save approximately $52.08 each month
