Answer:
Cat sleeps 420 hours than Alice in a month
Step-by-step explanation:
Given:
Number of hours Alice sleeps per night = 9 hours
Number of hours Cat sleeps per night = 20 hours
To Find:
How many more hours does a cat sleep in 1 month that Alice
Solution:
Let
The total number of hours for which Alice Sleeps in one month be x
The total number of hours for which Cat sleeps in one month be y
Step 1: Number of hours for which Alice Sleeps in one month
X = number of days in a month X Number of hours Alice sleeps per night
X = 30 X 9
X = 180 Hours
Step 2: Number of hours for which Cat Sleeps in one month
y= number of days in a month X Number of hours cat sleeps per night
y = 30 X 20
y = 600 Hours
Now ,
=> y – x
=>600 – 180
=>420 hours
True. Integers are whole numbers both positive and negative. Natural numbers are only whole positive numbers. So it is true whenever you are dealing with positive integers and it is false when you are dealing with negative integers.
We are given the equation of a line
y = -2x + 1
We have to find the value of y at three different values of x i.e. at x =0, -3 and 1
In order to find the value of y at any given x, simply replace x by that number.
So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)
Similarly for x=-3, we get:
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)
And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y= -1
This can be expressed as an ordered pair as (-1, -1)
solution:
P(passed)=P(Dr. J and passed)+P(Dr. S and passed) =0.4*0.8+(1-0.4)*0.6=0.68
hence probability that she was enrolled in Dr. J's section given passed
=P(Dr. J and passed)/P(passed)=0.4x0.8/0.68=0.4706
