How many defective telephones

Mathematics
1 answer:
zhenek [66]3 years ago
5 0

Answer:

Option 3: 300 phones

Step-by-step explanation:

Given

Phone produces each day: 1000

Number of phones that were checked = 30

Defective phones = 9

So the probability of defective phones will be calculated by dividing the number of defective phones by total number of phones checked.

So, the probability of defective phones

= 9/30

= 0.3 or 30%

So, from 1000 phones the defective phones will be:

1000*0.3

= 300 Phones ..

Answer:

The remaining side has a length of six units.

Step-by-step explanation:

We know that this is an Isosceles triangle because angles A and C are marked as being the same angle.  So we know that AB and CB are the same length.

As we're given their lengths, we can simply equate the two, and solve for x:

x + 4 = 3x - 8\\12 = 2x\\x = 6

So we know that the remaining side has a length of 6.

Solve the system of equations:<br> y = x-4<br> -2x + y = 18
Pie

Answer:

x = 7.3

Step-by-step explanation:

-2x + x-4 = 18

First, Combine Like Terms

-3x + (-4) = 18

Then, do Inverse Operations

-3x + -4 = 18

       + 4   +4

Cancel out the -4 +4 because it will equal zero and won't matter to the equation

-3x = 22

Do Inverse Operations again. In this case, you will divide.

-3x = 22

-3x/-3 = 22/-3

Cancel out the -3x/-3

22/-3 = x

7.3 = x
