Answer:
x > 3
Step-by-step explanation:
-7x < -21
Divide each side by -7, remembering to flip the inequality
-7x/-7 > -21/-7
x > 3
Answer:
a)
b)
c)
But we see that the distribution is defined ust between 49.62 and 50.04
And in order to find this we can use the CDF (Cumulative distribution function) given by:

And if we replace we got:

And makes sense since all the values are between 49.62 and 50.04
Step-by-step explanation:
For this case we define the random variable X ="net weigth in pounds of a packaged chemical herbicide" and the distribution for X is given by:

Part a
For the uniform distribution the expected value is given by
where X is the random variable, and a,b represent the limits for the distribution. If we apply this for our case we got:
Part b
The variance for an uniform distribution is given by:
And if we replace we got:
Part c
For this case we want to find this probability:
But we see that the distribution is defined ust between 49.62 and 50.04
And in order to find this we can use the CDF (Cumulative distribution function) given by:

And if we replace we got:

Answer:
B = R 100 000
Step-by-step explanation:
B will be <u> 2 </u> out of <u>4 + 3 + 2</u> = 2/9 of the total
2/9 * 450 000 = 100 000
2 1/2 pounds of apple makes serve 6
(2 1/2 x 24)/6 = 10 pounds of apple will make serve 24.
Therefore, she will use 10 pounds of apples.
