1 answer:
The height of statue is 12.2 inches in Troy's drawing.
Step-by-step explanation:
Given,
Actual height of statue = 305 feet
Scale used by Troy;
25 feet = 1 inch
1 feet =
305 feet =
305 feet =
305 feet = 12.2 inches

Answer:
Her expenses are $25 per week.
Step-by-step explanation:
Given :Jessica earns a commission on each sale but has to pay for her own expenses.
She writes the equation of the function like this: , where x is the number of doors she knocks on during the week and E(x) is her earnings for the week in dollars.
To Find: Which of the following are reasonable interpretations of the y-intercept of Jessica's function?
Solution:
x is the number of doors she knocks on during the week
E(x) is her earnings for the week in dollars.
Calculate y intercept
Substitute x = 0
Since E(x) is her total earning after clearing the payment of all her expenses.
So, 25 is her expenses per week.
Since we are given that she need to pay her expenses .
So, if there is no sale , still she need to pay expenses.
Thus the reasonable interpretations of the y-intercept of Jessica's function is Her expenses are $25 per week.
Answer:
The probability is 0.31
Step-by-step explanation:
To find the probability, we will consider the following approach. Given a particular outcome, and considering that each outcome is equally likely, we can calculate the probability by simply counting the number of ways we get the desired outcome and divide it by the total number of outcomes.
In this case, the event of interest is choosing 3 laser printers and 3 inkjets. At first, we have a total of 25 printers and we will be choosing 6 printers at random. The total number of ways in which we can choose 6 elements out of 25 is , where
. We have that
Now, we will calculate the number of ways to which we obtain the desired event. We will be choosing 3 laser printers and 3 inkjets. So the total number of ways this can happen is the multiplication of the number of ways we can choose 3 printers out of 10 (for the laser printers) times the number of ways of choosing 3 printers out of 15 (for the inkjets). So, in this case, the event can be obtained in
So the probability of having 3 laser printers and 3 inkjets is given by
