Suppose a box contains 3 defective light bulbs and 9 good bulbs. Three bulbs are chosen from the box without
replacement. What is the probability that at least one of the bulbs drawn is defective?

Answer:

No, It is not a function!

Step-by-step explanation:

Answer:

This is a linear graph.

Step-by-step explanation:

Since the x values increase at a constant of 1. The y-values have a 1st difference of -4 which means the graph is linear.

Answer:

Step-by-step explanation:

Let the length of the side of the square be x

Perimeter of the square = 4x

Let the sides of the triangle be s1, s2 and s3

If each side of the triangle is 3 inches longer than each side of the square, then

s1 = x+3

s2 = x+3

s3 = x+ 3

Perimeter of the triangle P = s1+s2 + s3

If the square and thr triangle have the same perimeter then;

perimeter of square = perimeter of triangle

4x = s1+s2+s3

4x =  x+3+ x+3+ x+3

4x = 3(x+3)

Hence the required equation is 4x = 3(x+3) where x is the side of the square.

Step-by-step explanation:

1. Solution for 3(6a)a=3 equation:

Simplifying

3(6a) * a = 3

Remove parenthesis around (6a)

3 * 6a * a = 3

Multiply 3 * 6

18a * a = 3

Multiply a * a

18a2 = 3

Solving

18a2 = 3

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Divide each side by '18'.

a2 = 0.1666666667

Simplifying

a2 = 0.1666666667

Take the square root of each side:

a = {-0.408248291, 0.408248291}

2.Solution for 5d(4)d=-2 equation:

Simplifying

5d(4) * d = -2

Reorder the terms for easier multiplication:

5 * 4d * d = -2

Multiply 5 * 4

20d * d = -2

Multiply d * d

20d2 = -2

Solving

20d2 = -2

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Divide each side by '20'.

d2 = -0.1

Simplifying

d2 = -0.1

Reorder the terms:

0.1 + d2 = -0.1 + 0.1

Combine like terms: -0.1 + 0.1 = 0.0

0.1 + d2 = 0.0

Answer:

90 and 90

Step-by-step explanation:

If they are perpendicular it means they cross at a 90 degree angle so since both L and M are perpendicular to N both the answers would be 90

Hope This Helps :)

The measure of the angle where line L meets line N is 90° ;

and the measure of the angle where line M meets line N is 90°.

In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).

Now it is given that,

Two distinct lines, L and M, are each perpendicular to the same line N.

Line L is perpendicular to line N.

Since angle between two perpendicular lines =  90°.

So, angle between line L and line N = 90°

Similarly, Line M is also perpendicular to line N.

Therefore, angle between line M and line N = 90°

Thus, The measure of the angle where line L meets line N is 90° ;

and the measure of the angle where line M meets line N is 90°.

Answer:

the answer is x equals 22 and y equals 8

Step-by-step explanation:

first equation is x+y=30

Second equation is x-y/2=7 that simplify's to x-y=14

then you add then so they will cancel out and you are left with 2x=44 so divide two by both sides which gives x=22

then you subsitute the 22 in the first equation. It will be 22+y=30 then you subtract 22 from the 30 that gives you y=8

so the two numbers are 22 and 8

Hope this helps!!!!

The numbers satisfying the given conditions are 22 and 8.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following problem -

Two numbers have a sum of 30. Half of their difference is 7.

We can write the equations as -

x + y = 30

1/2(x - y) = 7

Rearranging, we get -

y = - x + 30

y = x - 14

Plot the graph, the point of intersection is the solution. The number will be 22 and 8.

y = - x + 30

y = x - 14

Equating both, we get -

- x + 30 = x - 14

30 + 14 = 2x

2x = 44

x = 22

and

y = 22 - 14

y = 8

Therefore, the numbers satisfying the given conditions are 22 and 8.

Answer:

g > -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(g+4)=15

(5)(g)+(5)(4)=15(Distribute)

5g+20=15

Step 2: Subtract 20 from both sides.

5g+20−20=15−20

5g=−5

Step 3: Divide both sides by 5.

5g/5 = −5/5

G > -1

The solution of the inequality 5(g+4)>15 is g> -1.

Given Inequality:

5(g+4)>15

To solve the inequality, divide the inequality by 5

5(g+4) / 5 >15 / 5

g + 4 > 3

Now, subtract 4 from both side of inequality as

g + 4 - 4 > 3-4

g > -1.

Therefore, the solution is g > -1.
