Answer:
(1) <em>Y</em>-axis: number of students who spends respective hours studying.
(2) The number of students who spent 2 or more hours studying is 12.
(3) The number of students who spent fewer than 2 hours a night studying is 8.
Step-by-step explanation:
Consider the Frequency table and Histogram provided below.
(1)
The <em>y</em>-axis of the histogram represents the frequencies or the number of students who spends respective hours studying.
(2)
Compute the number of students who spent 2 or more hours studying as follows:
N (X ≥ 2) = n (X = 2 - 2:59) + n (X = 3 - 3:59) + n (X = 4 - 4:59)
Thus, the number of students who spent 2 or more hours studying is 12.
(3)
Compute the number of students who spent fewer than 2 hours a night studying as follows:
N (X < 2) = n (0 - 0:59) + n (1 - 1:59)
Thus, the number of students who spent fewer than 2 hours a night studying is 8.
I cant see the picture im sorry
Answer:
Then the alternate interior angles are congruent.
Answer:
1. So the porpotion should be 25/100 = x/120
You have this because you know that 25% of the dogs who go to ABC veterinarian need a rabies booster. So 100% of the dog should be 120 dogs, and now our job is to find how many dogs make up 25% percent of the total number.
According to our porpotion, we have:
(120 . 25)/100 = 30 (dogs)
Another way of understanding this is that you have to find 25% of the total amount, so just take that total number and multiply it with 25% or 25/100 which is 0.25 as well, that's why we multiply it with 25 first and then divide it to 100 later.

*I guess there is no need of explaining it
0.9 × 550 = 495
Answer:
8 months
Step-by-step explanation:
Given that:
Amount of money present in the bank account = $2,571.68
Automatic monthly rental payments for car loan = $321.46
Any deposits in the bank account are stopped.
To find:
The number of months taken so that the automatic payments make the value of the account as zero?
Solution:
Let the number of months taken to make the value of the account zero = 
months
To find the value of , we need to divide the total amount initially present in bank account with the monthly rental payment amount.
Therefore, the equation to find the value of , can be written as:
On solving the above equation, we get the value as following:
months
