Answer:
x = 6
Step-by-step explanation:
first you would put them equal because they have the same angle: 9x + 10 = 2x + 52
subtract 10 from both sides: 9x = 2x + 42
subtract 2x from both sides: 7x = 42
divide by 7 on both sides x = 6
hope this helps! :)
Answer: is there a picture?
Step-by-step explanation:
Answer:
The z-scores of both the mean and the median are zero.
Step-by-step explanation:
In a normal distribution, the mean and median values will be the same, in this case, 100. Therefore, both the mean and median will have the same score.
The z-score is given by:

For X = 100:

The z-scores of both the mean and the median are zero.
Answer:
Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:
https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php
you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis
Do you have a picture of the diagram that might help more
