Answer:
a
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
let x be the other leg to be found, then
155² = 124² + x²
24025 = 15376 + x² ( subtract 15376 from both sides )
8649 = x² ( take the square root of both sides )
= x
Hence x = 93 cm ← length of other leg → a
Number two should correspond for the graphs, with graph paper, just follow the color coded lines. Hope this helps.
Answer:
D
Step-by-step explanation:
If C represents the number of children you aren't gonna want to multiple like how it shows in option b and you aren't gonna wanna subtract.
Assuming the distribution is continuous, you have

If instead the distribution is discrete, the value will depend on how the interval of number between 1 and 29 are chosen - are they integers? evenly spaced rationals? etc
