The above two way table shows the number of girls and boys who scored below average and above average grades.
We have to find the probability that a randomly selected girl will have above average grades.
Probability is the measure of an likelihood that an event will occur.
Probability is calculated by the formula =
Total number of girls = 38
Number of girls Girls who have above average grades = 22
P(randomly selected girl with above average grades)= ![\frac{22}{38}](https://tex.z-dn.net/?f=%20%5Cfrac%7B22%7D%7B38%7D%20)
= 0.58
Answer:
1650 profit 10%
Step-by-step explanation:
Original Price of Watch = x
15% of x = x*15% = x*0.15
Given
Selling pirce = 1275
Original Price - 15% of original pirce = Selling Price
x-0.15x=1275
0.85x=1275
0.85x/0.85=1275/0.85
x=1500
Original Price of Watch = Rs. 1500
10% of 1500 = 10/100 * 1500 = 1/10 * 1500 = 1500/10 = 150
Selling price at 10% profit = 1500 + 150 = 1650
He sould sell watch to kae for Rs. 1650 to get a profit of 10%
When y is 0
x is -2
When x is 0
y is -4
The slope is negative -4/2 which is also -2/1 which is -2
Keep in mind its been a while since i did this type of work lol.....
did you try to draw it out on a grid paper....what will be helpful is if you got the coordinates and put the points down and then if you connect the dots you get your shape now you will count the unis in which the width and length is timed. so like if you had grid and it gave you coordinates and you did all that now you will count how many units is in the width and how many in the length.
but your best answer might be 14 units x 4 units
