Answer:

outcomes (top to bottom): SS, SG, GS, GG

all probabilities are 0.25

Step-by-step explanation:

Each outcome is identified by the labels on the ends of the corresponding tree branch, in order left-to-right. The top one is SS, for example, and the next one down is SG. Continuing down the tree, the outcomes are GS and GG.

Each letter has a probability of 1/2, so any pair of letters will have a probability of (1/2)(1/2) = 1/4 = 0.25.

This method of identifying outcomes and their probabilities can ensure that you find all outcomes. The sum of probabilities should be 1.00 if the tree is properly constructed.

Answers

Answer:

EFG = 104°

GFH = 76°

Step-by-step explanation:

The sum of a linear pair is always equal to 180°

So lets solve for the variable n

2n + 32 + 4n + 16 = 180

6n + 48 = 180

6n = 132

n = 22

So now we know N

EFG = 4n + 16

EFG = 88 + 16

EFG = 104°

GFH = 2n + 32°

GFH = 44 + 32

GFH = 76°

The sides of a rectangle are in a ratio of 7 : 4. If the perimeter of the rectangle is 176 ft, what is the area of the rectangle? The area of the rectangle is

Answers

Answer:

1792

Step-by-step explanation:

The sides of the rectangle is 7 and 4

7x, 4x

2(7x+4x) = 176

14x + 8x= 176

22x= 176

Divide both sides by the coefficient if x which is 22

x= 176/22

x= 8

= 7(8)

= 56

= 4(8)

= 32

Area of the rectangle

Answers

Answer:

B. 63

Step-by-step explanation:

There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.

Therefore:

(6 + 3)/3 = x/21

9/3 = x/21

3 = x/21

Cross multiply

21*3 = x

63 = x

x = 63

Caity is 50 inches tall. Caity's brother Michael is 5 inches taller than she is. What is Michael's height in feet and inches?

Which linear equation has a slope greater -1 but less than 0?
1. 5x+4y=20
2. 4x+5y=20
3. 5x-4y=20
4. 4x-5y=20

Answers

Answer:

2. 4x + 5y = 20

Step-by-step explanation:

Determine the slope of each of the equations;

y = mx + c

where;

m is the slope

In each of the given equations, make y the subject of the formula

1. 5x + 4y = 20

4y = 20 - 5x

y = (20/4) - (5x/4)

y = 5 - 5x/4

m = -5/4

2. 4x + 5y = 20

5y = 20 - 4x

y = 4 - 4x/5

m = -4/5 = -0.8

3. 5x - 4y = 20

4y = 5x - 20

y = 5x/4 - 5

m = 5/4

4. 4x - 5y = 20

5y = 4x - 20

y = 4x/5 - 4

m = 4/5

The question says, which of the slope is greater than - 1 but less than 0

- 1 < m < 0

The only equation with slope greater than -1 but less than 0 is 4x + 5y = 20, with slope -4/5 = -0.8

find the measure of angle G

Answers

Answer:

135 degrees

Step-by-step explanation:

It is as isosceles trapezoid, so the the base angles are congruent. The sum of the inner angles is 360 degrees

2(4x-7) + 2(11x -8) = 360

8x - 14 + 22x -16 = 360

30x = 390

x = 13

angle F = angle G

angle G = 11 * 13 - 8 = 135 degrees

Option (6)

Step-by-step explanation:

By applying sine rule the given triangle XYZ,

sin(X) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

Measure of opposite side (XY) = 12

Measure of Hypotenuse (XZ) = 37

113+90+90+12x+7=360(sum of four angles is always 360 degree)

300+12x=360

12x=360-300

x=60/12

x=5

Answer:

X = 5

Step-by-step explanation:

Shapes with 4 sides have angles that add to 360 degrees

So you have two right angles and 113 degrees.

This is

90+90+113=293

360-293=67

12x5=60

60+7=67

This means that x=5

Step-by-step explanation:

Complementary angles = 90°

90° = x + x+14

90° = 2x + 14

x = 52°

the next angle should be 52 - 14 = 38°

So x = 38°

So we are trying to get the “y” alone, so to undo the division by -8, we will multiply both sides by -8, then simplify.

(-8) y/(-8) = (-8) 1/16

y = -8/16

Ken is thinking of a number. Nine more than the product of 4 & the number is 73. Find Ken's number.

Answers

Answer:

x = 16

Step-by-step explanation:

Let the unknown number be x.

Translating the word problem into an algebraic expression, we have;

4x + 9 = 73

4x = 73 - 9

4x = 64

x = 64/4

x = 16

Therefore, the unknown number is 16.

Answer:

angle FDA = 75 degrees

angle JAI = 75 degrees

Step-by-step explanation:

In ΔDCE,

angle D + angle C + angle E = 180......(sum of the interior angles of a triangle is always 180 degrees)

angle D + 80 + 25 = 180

angle D + 105 = 180

angle D = 180 - 105

angle D (I. e angle CDE ) = 75 degrees

Now, angle CDE and angle FDA are vertically opposite angles, so,

angle CDE = angle FDA..... (vertically opposite angles are congruent to each other)

therefore, angle FDA = 75 degrees

Now, angle CDE and angle BAD are corresponding angles, so,

angle CDE = angle BAD...... ( corresponding angles are congruent to each other)

angle BAD = 75 degrees

Now, angle BAD and angle JAI are vertically opposite angles, so,

angle BAD = angle JAI..... (vertically opposite angles are congruent to each other)

therefore, angle JAI = 75 degrees
