A box contains 10 light bulbs, of which 3 are defective and the other 7 work. If two bulbs are drawn in succession without replacement, what is the probability of getting 1 working bulb and 1 defective bulb?

Answer:

29

Step-by-step explanation:

The length of side b is 36.

Triangle 1 and 2 are similar triangles. In order to determine the length of side b, the ratio of the lengths given has to be determined.

45/10 = 4.5

This means that triangle 2 is 4.5 times larger than triangle 1.

Length of side b = 4.5 x 8= 36

Answer:

(7x4-x2+10x+15) / (x+1)

Step-by-step explanation:

The diameter of a tire is the distance across the tire through the center. Since tires are circular, you can find the circumference of the tire from the diameter. The circumference represents the distance the tire travels when it makes one revolution. If you know the number of inches in a mile and the circumference, you can find the number of times the wheel turns per mile.

First, measure the diameter of the tire in inches.

Secondly, multiply the diameter by pi, which is approximately 3.1416, to find the tire circumference. For example, if the tire has a 20 inch diameter, multiply 20 by 3.1416 to get 62 inches.

Answer:

finding the product of 9,10,and 9

810

Step-by-step explanation:

Answer:

-√1/5

Step-by-step explanation:

If the product of 5 and w to the second power is equal to the sum of 9 and k, this is expressed as;

(5w)² = 9 + k

Given that k = -4, on substituting;

(5w)² = 9 + (-4)

(5w)² = 9-4

(5w)² = 5

25w² = 5

5w² = 1

w² = 1/5

w = ±√1/5

w = -√1/5

Hence the NEGATIVE value of w is -√1/5

Step-by-step explanation:

So lets work this out:

First, we will need to convert 85 cm to meters. That would be 0.85 meters.

Now we can take 0.85 meters and subtract it from 3.6. This equals 2.75.

Dimensions of cube = 1 in × 1in .

No. of cubes in each layer = 15 .

No. of layers = 2 .

• Therefore the volume of one cube :-

[tex]\tt \to Volume_{(cube)}= side^3 = (1 \ in.)^3 = \red{1in.^3}[/tex]

• Therefore the volume of one layer :-

[tex]\tt\to 1\ in.^3\times 15 =\orange{15\ in.^3} [/tex]

• Therefore the volume of whole box :-

[tex]\tt\to 2\ in.^3\times 15 =\orange{30\ in.^3} [/tex]

Therefore our required answer is 30 inch ³.

15x2=30 polegadas

Answer:  2/8  

Step-by-step explanation: becau

Here, we have to write a fraction equivalent to [tex]\sf{ \dfrac{1}{4}} [/tex].

Multiply 2 with the numerator and the denominator of the fraction.

→ [tex]\sf{ \dfrac{1}{4} = \dfrac { 1 \times 2}{ 4 \times 2} } [/tex]

→ [tex]\sf{ \dfrac{1}{4} = \dfrac { 2}{ 8} } [/tex]

So, a fraction equivalent to [tex]\sf{ \dfrac{1}{4}} [/tex] is [tex]\sf \red{ \dfrac{2}{8}} [/tex].

Similarly, we can multiply with another numbers (ex : 3,4,5,6) with numerator and the denominator of the given fraction to find the fractions equivalent to the given fraction.

Hi

Let's call X  the amount in the beginning.  

we  have X*1.03^6 = 1819.77

                X =  1819.77 /  1.03^6

                X ≈ 1524.03

Answer:

(a) Same slope and different y intercept

Step-by-step explanation:

Given

[tex]y = \frac{3}{7}x + 11[/tex]

[tex]-3x + 7y = 13[/tex]

Required

Are the lines, parallel?

To do this, we first convert both equations to slope intercept;

[tex]y = mx+ b[/tex]

Where

[tex]m = slope[/tex]

So, we have:

[tex]y = \frac{3}{7}x + 11[/tex]

[tex]-3x + 7y = 13[/tex]

Solve for 7y

[tex]7y = 3x + 13[/tex]

Solve for y

[tex]\frac{7y}{7} = \frac{3x}{7} + \frac{13}{7}[/tex]

[tex]y = \frac{3}{7}x + \frac{13}{7}[/tex]

So, the two equations are now:

[tex]y = \frac{3}{7}x + 11[/tex]

[tex]y = \frac{3}{7}x + \frac{13}{7}[/tex]

When two lines have the same slope but different y intercepts, then they are parallel.

Recall that:

In [tex]y = mx + b[/tex]

[tex]m = slope[/tex]

[tex]b = y \ intercept[/tex]

So:

In [tex]y = \frac{3}{7}x + 11[/tex] and [tex]y = \frac{3}{7}x + \frac{13}{7}[/tex]

The slopes are:

[tex]m = \frac{3}{7}[/tex] and [tex]m = \frac{3}{7}[/tex]

The y intercepts are:

[tex]b = 11[/tex] and [tex]b = \frac{13}{7}[/tex]

Since the values of m (the slope) are the same and the values of b (the y intercepts) are differenr, then they are parallel
