Define probability. Each number from 1 to 20 is written on a slip of paper and placed in a hat. If a slip of paper is randomly-chosen from the hat, determine the probability that a prime number will be selected.

Answer:

-11/4

Step-by-step explanation:

The y intercept has the coordinates of (0,2)

We have two points (0,2) and (4,-9) so we can find the slope using

m= (y2-y1)/(x2-x1)

   = ( -9-2)/(4-0)

   = -11/4

Answer:

-11/4

Step-by-step explanation:

y = mx + c

Point (x,y)

intercept c

slope m

-9 = m(4) + 2

-9 = 4m + 2

make m the subject of the formula

4m = -9-2

4m = -11

divide both sides by 4

m = -11/4

Answer:

150.8cm

Step-by-step explanation:

Area= π r²

make r subject of the formula

A = π r²

A/π= πr² (dividing both sides by π)

r²= A/ π

r =

[tex] \sqrt{ \frac{a}{\pi} } [/tex]

r=√(1809.56)/(π)

r=√576.0008

r≈24cm

:. circumference= 2π r

= 2× π × 24

=150.7964

≈150.8cm

Answer:

y = -2x + 8 (B)

Step-by-step explanation:

Just expand y + 2 = -2(x-5)

y + 2 = -2x +10

y = -2x +8 (minus both sides by 2)

Answer:

23,11333753

Step-by-step explanation:

1. Use The Coordinates To Find The Distances Of The Four Sides

2. The Formula For Perimeter Or A Quad =

AB + BC + CD + AD

Basically Add The Distances Of The Four Sides

So: WX + XY + YZ + WZ

[tex] \sqrt{34} + 5 + \sqrt{61} + 2 \sqrt{5} [/tex]

= 23,11333753

.°. 23,1

b.????

We can write the parameter as -

In geometry a quadrilateral is a four-sided polygon, having four edges and four corners.

Given is that WXYZ has vertices W(6, 2), X(3, 7), Y(-1, 4), and Z(4, -2).

       {d} = √{(x₂ - x₁)² + (y₂ - y₁)²}

{ a } -

WX = 5.83

XY = 5

YZ = 7.8

ZW = 4.5

So the perimeter would be -

P = WX + XY + YZ + ZW

P = 5.83 + 5 + 7.8 + 4.5

P = 23.13

{b} - After the dilation, the sides will become -

WX' = 5.83/2 = 2.9

XY' = 5/2 = 2.5

YZ' = 7.8/2 = 3.9

ZW' = 4.5/2 = 2.25

The perimeter will be -

P = WX' + XY' + YZ' + ZW'

P = 2.9 + 2.5 + 3.9 + 2.25

P = 11.55

Therefore, we can write the parameter as -

Answer:

a

Step-by-step explanation:

Answer:

8 cm

Step-by-step explanation:

[(x+5)*2.5]/2 =  16.25

(x+5)*2.5 = 32,5

2.5x + 12,5 = 32,5

2.5x = 20

x = 8

Let x = 3

f(3) = -(3)^2

f(3) = -(9)

f(3) = -9

Answer:

the answer is 4.5 in term of the measurement because Figure A has a larger scale and B has a smaller scale

Answer:

0.25

Step-by-step explanation:

Divide one side of Figure B by the congruent side of Figure A and you would get the scale factor.

If you multipy every side of figure A by 0.25 you would get the sides of figure B.

Complete question :

It takes 313131 employees and \$7500$7500dollar sign, 7500 to build a car, and it takes 191919 employees and \$4300$4300dollar sign, 4300 to build a motorcycle. Genghis Motors wants to spend more than \$84000$84000dollar sign, 84000 to build cars and motorbikes using at most 706706706 employees. Let CCC denote the number of cars they build and MMM the number of motorbikes they build. Write an inequality that represents the condition based on the number of employees. Write an inequality that represents the condition based on the number of dollars.

Answer:

31C + 19M ≤ 706

7500C + 4300M > 84000

Step-by-step explanation:

C = number of cars built

M = number of motorcycles built

Cost of building a car :

Cost = 31 + $7500

Cost of building a motorcycle,:

Cost = 19 + 4300

To build, C cars :

Number of employees = 31C

7500 * C = 7500C

To build, M motorcycles :

Number of employees = 19M

4300 * M = 4300M

Genghis budget :

Amount > 84000

Number of employees ≤ 706

Hence, the constraints

31C + 19M ≤ 706

7500C + 4300M > 84000

Answer:

1 woman isnt married

Step-by-step explanation:

right?

Answer:

5 females aren't married

Step-by-step explanation:

25 teachers

16 married

15 women

6 MALES aren't married

16 married teachers - 6 not married men = 10 married teachers

15 of those teachers are female so,

15 - 10 = 5

5 female teachers not married.

Answer:

18 7/12 miles

Step-by-step explanation:

Luis is running a 26 mile marathon. He has completed 7 5/12 miles so far. How much farther does he have to run?

We solve the above question using the Subtraction operation

= 26 miles - 7 5/12 miles

= 26 miles - 89/12 miles

Lowest Common Denominator = 12

= 26/1 miles - 89/12 miles

= 312 - 89/12

= 223/12

= 18.583333333 miles

= 18 7/12 miles

He has 18 7/12 miles farther to go

Answer:

7.5

35.2

1.5

20

Step-by-step explanation:

1. vertical angles are equal

(2x+17)=(4x+2)

15= 2x

x= 7.5

2. adjacent angles equal 180

(2m+8)+(3m-4)= 180

5m+4= 180

5m= 176

m= 35.2

3. (30s+5)=(20s+20)

10s= 15

s=1.5

4. 4p+5p=180

9p=180

p=20
