Answer:
Step-by-step explanation:
a) <u>Number of girls:</u>
<u>Percentage:</u>
b) <u>Number of students prefer watching TV:</u>
<u>Percentage:</u>
Answer: No
Step-by-step explanation:
No, because 4^2 is 16, 8^2 is 64, 10^2 is 100 and 16+64 = 80 and 80≠100
You add 1/4. Because 19/4 is 4 3/4.
Answer:
Step-by-step explanation:
A) License plates are made using 3 letters followed by 3 digits
If repitition is allowed we have
number of plates = ![(26)^3 (10)^3 =17576000](https://tex.z-dn.net/?f=%2826%29%5E3%20%2810%29%5E3%20%3D17576000)
Option B
Out of 10 members 6 can be selected in
10C6 =210
Option B
3 tax returns from 13 can be selected in
13C3 =286
Option D
Prob of taking 3 cherry from 11 cherries is
6C3/11C3=20/165=0.1212
Option B
Slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
Let's find m, the slope:
The formula for slope when using two points on a line is:
In this case...
^^^Plug these numbers into the formula for slope...
![\frac{-2}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B-2%7D)
1
^^^This is your slope
So far this is our equation:
y = 1x + b OR y = x + b
Now let's find b, the y-intercept:
To do that you must plug in the point the line goes through in the x and y of the equation.
For this question I have chosen to plug in the point (-1, -5)
-5 = -1 + b
-5 + 1 = -1 + 1 + b
-4 = 0 + b
-4 = b
Your equation is:
y = x - 4
Hope this helped!
