The probability is 0.5
rounded off is just 0.50
The function of 5 (or y when x is 5) can not be determined with this little information.
Answer:
x = 7/
or 4.949747468
Step-by-step explanation:
45-45-90 triangles have a specific pattern.
The smaller sides are x, & the hypotenuse is 
With this knowledge, we know we have to divide the hypotenuse by
to get the smaller sides, so we divide 7 by the
to find x.
The answer is 2 1/5 because 1 3/8 is =11/8 TIMES 2/5 IS 2 1/5
