The expression that evaluates to true if a discount should be given is:
<h3>What is the meaning of the expression?</h3>
The symbols above represent less than and greater than respectively. So, the instruction is that children who are less than 10 should be given a discount while those who are greater than 55 should also be given a discount.
So, the symbols as used respectively are less than and greater than. So, the expression provided above is correct.

The correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is; 1
<h3>What is the Correct Scale Calibration?</h3>
We are told that a certain scale is not calibrated correctly,
Mass displayed = 0.75 kg (less than its actual mass).
The scale of display = 1
Thus, the correlation between actual mass and displayed mass is 1 due to the fact that correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.
Thus, the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is 1.

Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again
Simple
Nine less than a number times four equals fifteen
basically, x*4-9=15 would be your equation, or something similar
Well, we know x can't equal 1,2,3,OR 4. Five is also out, because 5*4=20-9=11, so cross that out.
But if you try doing 6*4-6=15, it fits.
6*4=24, 24-9=15
Thus, x=6, so your answer to Nice less than four times a number equals fifteen is 6.
~Hope this helps!
