what is the question??
Answer:
49 red marbles
Step-by-step explanation:
There is a bag with only red marbles and blue marbles.
We are told in the question that:
The probability of randomly choosing a blue marble is 2/9 . There are 63 marbles in total in the bag
Hence: since
P(Blue marbles) = 2/9
Hence,
The number of blue marbles = 63 ÷ 9
= 7
Hence:
2 × 7/9 × 7 = 14/63
Hence, the number of blue marbles = 14 blue marbles
The number of red marbles bus calculated as:
63 - 14 blue marbles
= 49 red marbles
we know that
The formula to calculate the slope between two points is equal to
we have
Step 1
<u>Find the slope GH</u>
substitute in the formula
Step 2
<u>Find the slope HJ</u>
substitute in the formula
Step 3
<u>Find the slope JG</u>
substitute in the formula
Step 4
Verify if triangle GHJ is a right triangle
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so
compare slope GH with slope JG
we have
-----> side GH and side JG are perpendicular
The triangle GHJ is a right triangle
The answer in the attached figure
Slope or m is -2
Y intercept or b is (0,-1) or -1
