The reason you chose the form y=mx+b is because that is the equation of any straight line, also known as a linear equation.
Since they have the same denominator (4) which is the number on the bottom of the fraction, you can just add the numerators (3 and 4), which are on the top of the fraction, together:
3/4 + 4/4 = 7/4
Answer:
the probability that the average diameter of those sand dollars is more than 4.73 centimeters is 0.5910
Step-by-step explanation:
Given information:
mean, x = 5
standard deviation, σ = 0.9
number of sample, n = 16
now we calculate the probability that the average diameter of those sand dollars is more than 4.73 centimeters.
P(x>4.73) = P (z > (4.73 - x) / (σ
)
= P (z > (4.73 - 4) / (0.9
)
= P (z > 0.203)
= 0.5910
For this case, the first thing you should do is know that dilation is a transformation that is used<em> to lengthen or shorten a geometric figure.
</em>
Geometric figures can be triangles, squares, circles, or any polygon.
There is a point on the plane, at which the dilation begins to be drawn.
This point on the plane is what we know as the center of dilation
.
Answer:
B. the center of dilation
