Answer:
X=-10
Step-by-step explanation:
Flip it
7X=-70
Divide both sides by 7
7x/7= -70/7
Answer:
(p green) 1/3
(p red) = 1/2
Step-by-step explanation:
Add the number of balls together to get the total.
3 + 7 + 5 = 15
Find the probability of choosing green.
(p green) = 5/15
reduce by 5
(p green) 1/3
Since you kept the green ball, there are now a total of 14 balls.
Find the probability of choosing red.
(p red) = 7/14
reduce by 7
(p red) = 1/2
Answer:
3
Step-by-step explanation:
Alright so here's the deal. Fractions are basically a way to represent a part of a whole item (or number). The number on the bottom (denominator) is the number of pieces that the item is broken into and the number on top (numerator) is how many of those pieces you have you have. For example. If you take a cup and pour it evenly into 3 glasses, you will have broken it into 3 parts. Each glass now contains 1 out of the 3 total parts.
If you need any more help or don't understand part of my answer just let me know!!
The probability that the machine produces fewer than 5 defective widgets in a production run of 100 items is 0.10
<h3>What is the probability?</h3>
A probability refers to the ratio of favorable events to the n number of total events.
Also, it means the chance that a particular event (s) will occur expressed on a linear scale from 0 to 1 which can also be expressed as a percentage between 0 and 100%.
<u>Given data</u>
An industrial machine produces 5 widgets.
It has a 0.07 defective rate.
Defective rate fewer than 5
Total Probability = P of 4 defective + P for 3 defective + P for 2 defective + P for 1 defective.
Total Probability = 4/100 + 3/99 + 2/98 + 1/97
Total Probability ≈ 0.10
Therefore, the required probability for fewer than 5 defective rate is 0.10
