A set of exam marks has mean 70,median 65, inter-quartile range 25 and 15 Marks. It is decided to 10 from all the marks. For the new set of marks (a)what is the new mean (b)what is the new median (c)what is tje new inter-quartile range? (d)what is the new SD?​

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
