Answer: Part A: In which grade did the students do the best? Answer; 4th grade, they have a higher median of 68
Part B: what best describes the shape of the two graphs? Answer: 5th grade is roughly symmetrical without letters in fourth grade is skewed right
Step-by-step explanation: That’s for the answers for the 3rd question on Topic 4 of Section 9. Hope that helped:))
The time the difference between two decimals is an integer is when the decimal value is the same for both numbers. For example, 1.20 - 0.20 = 1. 1.20 and 0.20 are decimals while 1 is an integer. 0.20 is the decimal value while 1 is the whole number.
1.) 3.5% * 500 = 17.5
2.) 70.0% * 50 = 35.0
3.) 25.0% * 440 = 110.0
4.) 10.0% * 46 = 4.6
86 because out of all of the answer choices there are 2 small arcs and QR is the second smallest and 86 is the second smallest number so it kinda makes sense
The minimum y-value of the function for the parabolic equation is -13.
<h3>What is the vertex of a parabolic equation in quadratic form?</h3>
The vertex for an up-down facing parabola of the form y = ax² + bx + c is 
From the given equation:
y = x² + 8x + 3
The parameters for the parabola are:
a = 1, b = 8, c = 3
If we replace the value of to find the minimum value of 
value, we have:
Thus, the parabola vertex is (-4,-13). If a< 0, the vertex is a maximum value and If a>0, the vertex is a minimum value.
