Answer:

3.88%

Step-by-step explanation:

The probability that 1 is defective and 3 are not (out of four) is ...

P(1 of 4) = 4(0.01)(0.99)^3 ≈ 0.0388 = 3.88%

The multiplier of 4 comes from the number of ways that 1 can be chosen from 4.

Answer: yes

Step-by-step explanation:

solve for y. will give brainiest

Answers

Answer:

y = 81°

Step-by-step explanation:

let the 5 th angle in the pentagon be x

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, then

sum = 180° × 3 = 540°

sum the angles and equate to 540

x + 95 + 125 + 116 + 105 = 540

x + 441 = 540 ( subtract 441 from 540 )

x = 99°

x and y are adjacent angles and supplementary, sum to 180° , that is

x + y = 180°

99° + y = 180° ( subtract 99° from both sides )

y = 81°

5(4x-10)+10x = 4(2x-3)+ 2(x-4)? is equal to - 7/4 or - 1/4 or 3/20 or 3/2 ?

Answers

Answer:

x is equal to 3/2

Step-by-step explanation:

Let's solve it!

5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)

expand:

20x - 50 + 10x = 8x - 12 + 2x - 8

group like terms:

30x - 50 = 10x - 20

factor out common multiples:

3x - 5 = x - 2

group terms again:

3x - x = -2 + 5

2x = 3

and divide both sides by two:

x = 3/2

What is the equation of a line with Point A(0, 4) and Point B(2,-6) ?

Answers

9514 1404 393

Answer:

y = -5x +4

Step-by-step explanation:

The slope can be found using the slope formula:

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

m = (-6 -4)/(2 -0) = -10/2 = -5

The point (0, 4) tells you the y-intercept is b = 4. So, the equation in slope-intercept form is ...

y = mx +b . . . . . where m is slope and b is y-intercept

y = -5x +4

Sasha walks at a constant rate. She meets her friend Hannah 0.6 kilometer along the way, and thet continue walking at the same constant rate. When thay get to school, Sasha has walked for 0.6 hour and Hannah has walked 0.45 hour. What is the rate in kilograms per hour at which they walked to school

Answers

Answer:

4 km/hr

Step-by-step explanation:

Sasha walks at a constant rate. She meets her friend Hannah 0.6 kilometer along the way, and they continue walking at the same constant rate. When thay get to school, Sasha has walked for 0.6 hour and Hannah has walked 0.45 hour.

Let

the rate of the speed at which they walked to school be represented by r

Distance to school for Sasha = Distance to school for Hannah

Distance = Speed (rate × time)

Hence:

0.6r = 0.45r + 0.6

Collect like terms

0.6r - 0.45r = 0.6

0.15r = 0.6

r = 0.6/0.15

r = 4 km/hr

The rate in Kilometer per hour at which they walked to school is 4km/hr

Answers

Answer: D. 150

Step-by-step explanation:

Given equation: [tex]3(3x-10)=5(x+10)[/tex] , it shows the relationship between the perimeter of an equilateral triangle and the perimeter of an equilateral triangle.

Consider [tex]3(3x-10)=5(x+10)[/tex]

[tex]\Rightarrow\ 9x-30=5x+50\\\\\Rightarrow\ 9x-5x= 50+30\\\\\Rightarrow\ 4x= 80\\\\\Rightarrow\ x=\dfrac{80}{4}\\\\\Rightarrow\ x= 20[/tex]

Now, perimeter of pentagon = 5(x+10) = 5 (20+10)

= 5(30) = 150

Hence, option D is correct.

Step-by-step explanation:

how do you solve this using the substitution method?

Answers

Answer:

x=13, y=36

Step-by-step explanation:

y−2x=10

6x−2y=6 −2x+y=10

6x−2y=6

6x=2y+6

x= 1/6(2y+6)

x=1/3y+1

-2(1/3y+1)+y=10

-2/3y-2+y=10

1/3y=12

y=36

Substitute y to check your answer

x=1/3*36+1

x=12+1

x=13

Answer:

b = 43

Step-by-step explanation:

So let's plug things in first:

y= 2x - 20 and y= -5x +b which can become →

2x - 20 = -5x + b (now you said that x=9 so let's plug that in)

2(9) -20 = -5(9) + b (now try solving that)

18 -20 = -45 + b → -2 = -45 + b ( so then add 45 to both sides)

43 = b ( and there's your answer )
