Answer:
In a coordinate axis, the horizontal line is called the x-axis, and the vertical line is called the y-axis.
1) Then if you have a point (x, y), to graph this you go at the horizontal axis to find the value x,
2) Starting from the point you already found, now you need to move y units in the vertical axis.
Now we want to graph the point (0, 3.5).
First we need to locate the value 0 in the horizontal axis, this is the point where both axes intersect.
Now we move 3.5 units, because the number is positive, we move 3.5 units upwards.
The graph of the point is shown below.
Answer:
0.15866
Step-by-step explanation:
First, we calculate z-score
Mathematically;
z-score = value-mean/SD
here, mean = 47 , SD = 5 and value = 52
z-score = (52-47)/5 = 5/5 = 1
The probability we want to calculate is;
P(z<1) and we can access this from the standard score table
P(Z<1) =0.15866
600 mean 100%
x ---------- 7%
-------------------------
x = 600*7/100 = 6*7 = 42

A quadratic equation is a polynomial with an order of two. Its general form is ax² + bx + c = 0. From the choices given, the first option seems to be the quadratic equation. Simplifying the equation gives 6x² + 18x + 27 = 0.
