A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 15 bulbs?

Answers

Answer:

2

Step-by-step explanation:

Given that:

Flawed bulbs = 4

Not flawed = 26

Total examined = (flawed + not flawed)

Total examined = (4 + 26) = 30

P(flawed) = flawed / total

P(flawed) = 4 / 30 = 0.1333333

If 15 is examined :

Expected number of flawed bulbs :

(4/30) * 15 = 2

In ΔMNO, n = 92 inches, ∠N=119° and ∠O=20°. Find the length of m, to the nearest 10th of an inch.

Answers

Answer:

Step-by-step explanation:

The length of the side of the triangle will be 69 inches.

What is the sine law?

The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.

The sine law in the triangle ΔMNO is given as,

n / sin N = m / sin M = o / sin O

The third angle is calculated as,

∠M + ∠N + ∠O = 180°

∠M + 119° + 20° = 180°

∠M = 41°

The length m is calculated as,

n / sin N = m / sin M

92 / sin 119° = m / sin 41°

m = 69 inches

The length of the side of the triangle will be 69 inches.

More about the sine law link is given below.

Answer:

x=1

Explanation:

3x+4*2x=11

(We move all terms to the left)

3x+4*2x-(11)=0

( We multiply elements )

3x+8x-11=0

(We add all the numbers together, and all the variables )

11x-11=0

( We move all terms containing x to the left, all other terms to the right )

11x=11

x=11÷11

Step-by-step explanation:

I created a proportion from similar sides HB ≈ LY and NH ≈ RL

28/21 = (3x - 7)/(x + 11)

then cross-multiply to get

28(x + 11) = 21(3x - 7)

28x = 63x - 455

Peter works two part time jobs. He is paid $6 er hour at job a and $9 per hour at job b. Last wee eter worked a total of 24 hours at both jobs and madr $189. Hobmny hours dud peter work at job a?

Answers

Answer: Peter worked 9 hours at job a

Step-by-step explanation:

Step 1

Let the number of hours worked in  job a = x

and number of hours worked in job b = y such that the total hours worked would be expressed as

x=y= 24 ---eqn 1

also since $6 and $9 dollar are paid per hour for the job  and the total amount made is $189, it should be expressed as

6x + 9y =$189--- equation 2

Step 2

Now we have gotten two expressions to solve for number of hours, we can now solve

x+y= 24 ---eqn 1

6x + 9y =$189--- eqn 2

Using elimination method, we multiply equation 1 by 6 and subtract from equation 2

6x + 9y =189

-6x+6y=144

3y=45

y= 45/3 =15

To find x

x+y = 24

x+15=24

x= 24-15

x= 9

fff

Therefore Peter worked 9 hours at job a  and 15 hours at job b
