Answer:
a) Figure attached
b) For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:
Step-by-step explanation:
For this case we define the random variable X= depth (in centimeters) of the bioturbation layer in sediment for a certain region, and we know the distribution for X, given by:
Part a
For this case we can see the figure attached.
Part b
For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:
Answer:
He needs to work for 40 whole hours
Step-by-step explanation:
In this question, we are tasked with calculating the amount a Tv will cost Bob in terms of the number of hours he needs to work.
Let’s look at the total cost he has to pay.
a. $500
b. 8% tax = 8/100 * 500 = $40
c. He is paying 2 bills of $35 each making a total of 2 * $35 = $70
The total amount he is to pay is thus; 500 + 40 + 70 = $610
Let’s look at his income ;
a. Bonus $45
b. Birthday gift $85
The total amount of money he has asides his salary to offset the bill is 45 + 85 = $130
The balance to pay from his salary would be $610 - $130 = $480
The number of hours he has to work since he earns $12 per hour would be 480/12 = 40 hours of work
Answer:
The number is 8 because 
And if you add 4, you get 20
Hence, the number is 8
Well a yard is 3 ft
so divide 3 into 13
3 goes into 13 4 times and you get 12
you have 4 whole yards and 1 ft left or 1/3 of a yard.
