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 ..

You bike 3 miles the first day of your​ training, 3.3 miles the second​ day, 3.9 miles the third​ day, and 5.1 miles the fourth
docker41 [41]

Answer:

The answer to your question is 21.9 mi

Step-by-step explanation:

Data

1st day = 3 mi

2nd day = 3.3 mi

3rd day = 3.9 mi

4rd day = 5.1 mi

7fh day = ?

Process

1.- Calculate the pattern

Day            1           2           3         4        5          6         7

MIles          3          3.3         3.9     5.1    7.5       12.3     21.9

Gradient          0.3         0.6       1.2    2.4    4.8      9.6

We notice that the gradient is duplicating so the miles that I bike the seventh day are 21.9.
