Answer:
105 inventions
Step-by-step explanation:
Find how many inventions Inventor B had by dividing 630 by 6:
630/6
= 105
So, Inventor B had 105 inventions
The answer is B which is (x-9)(x+4)

Answer: 0.6826894
Step-by-step explanation:
Given : The length of similar components produced by a company are approximated by a normal distribution model with a 5 cm and a 0.02 cm.
Let x be the random variable that represents the length of similar components produced by a company.
z-score :
For x= 4.98
For x= 5.02
By using the standard z-value table (right -tailed) , the probability that the length of this component is between 4.98 and 5.02 will be :_
Hence, the probability that the length of this component is between 4.98 and 5.02= 0.6826894
Answer:
Step-by-step explanation:
I think the question below is the one you wanted to ask:
<em>A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 6 centimeters per minute. After 20 minutes, the water level is 220 centimeters
</em>
<em>Graph the pool's water level (in centimeters) as a function of time (in minutes).</em>
Here is my answer:
To draw the linear line, we need to identify the equation that modles this situation. As we know the water level rises at a rate of 6 cm per minute which mean the slope m = 6
The standard form is: y = mx + b <=> y = 6x + b
After 20min the water level is 220 cm
<=> 220 = 6(20) +b
<=> b = 100
So your equation is : y = 6x + 100 and the initial amount of water in it is 100
