The probability that in any one sample, two calculators or less will be faulty is; 100%

<h3>Probability and Random sampling</h3>

According to the task content;

  • A statement of fact indicates that; 20% of the calculators produced in a factory are faulty.

Hence, it follows that, when a sample of 10 calculators is selected randomly each day, 2 of the calculators are faulty by proportion.

Ultimately, the probability that in any one sample, two calculators or less will be faulty is; 100%.

Can someone explain how to do this cuz my computer ain’t doing such a good job
RideAnS [48]

Answer:

L=36

W=6

Step-by-step explanation:

If the length is six times the width than the width is equal to x. This would make the length 6x or 6 times x. The perimeter of the rectangle is all of the sides added together. So 6x+6x+x+x=14x

The perimeter equals 84 which gives you

14x=84

Divide by 14 on each side and x=6

The length is six times longer than the width which is 6x6 or 36 and the width would just remain 6.

-4x+5 + -13x+39=180 angle measure
mylen [45]

Step-by-step explanation:

−4x+5−13x+39=180

Step 1: Simplify both sides of the equation.

−4x+5−13x+39=180

−4x+5+−13x+39=180

(−4x+−13x)+(5+39)=180(Combine Like Terms)

−17x+44=180

−17x+44=180

Step 2: Subtract 44 from both sides.

−17x+44−44=180−44

−17x=136

Step 3: Divide both sides by -17.−17x

−17

=

136

−17

x=−8

Answer:

x=−8
