Answer:
Step-by-step explanation:
Assuming this is a linear equation in the form of 
, we can first solve for the slope using 
, for these points, the slope would be 
. Now we plug in the points to get the equation:
plugging in (7,5), we get 
×
+ 
and solving for b, we get b = 
therefore, the equation of the line passing through (7,5) and (1,2) is .
hope this helps!
Answer:
280 mangoes
Step-by-step explanation:
sum the parts of the ratio, 7 + 11 = 18 parts
Divide the total by 18 to find the value of one part of the ratio.
720 ÷ 18 = 40 ← value of 1 part of the ratio , then
7 × 40 = 280 ← number of mangoes
Answer:
area of the two faces plus sides
Don’t take my word for it but I think 3rd option
So, the total number of balls is 11. We want to pick 2 red balls and 1 green ball. WLOG (since order doesnt matter here), we can say he picks red, green, red. That means on his first pick, he has a 
chance of picking the red ball, and he places it back in the bag. The probability of picking a green ball is 
, and then he places the ball back in the bag. The probability of picking the last red ball is the same as the last red ball example, and we simply multiply the probabilities together as per the multiplication rule to get:
Now, without replacement the order does matter. He picks a red ball, a red ball then a green ball. The probability of picking the first red ball is
, and the probability of picking the second red ball is 
and the probability of picking the green ball is
. We want to multiply thm again, as per the multiplication rule like the last problem.
