Answer:
first 25%
Step-by-step explanation:
A quartile is a quarter, so the first 25% falls between the minimum and lower quartile
Answer:
1
Step-by-step explanation:
By order of operations, we first evaluate the parentheses, which is 2 * 1 = 2. We then evaluate the brackets, which are 3 / 2 = 
. Finally, * 
= 
or 1.
Answer:
y = 2x
the formula for linear equations are y = mx+c,
where m is the gradient,
and c is the y-intercept
to find m (the gradient):
1. pick to points on the graph (eg. -2,-4 and 2,4)
2 substitute the values into the formula for gradient y2-y1/x2-x1.
m = y2-y1/x1-x2
= -4 -4/-2-2
= -8/-4
= 2
to find c (y-intercept):
- the y-intercept is where the graph cuts the y axis
- in this graph, the y-intercept is 0
hence,
c = 0
substitute m = 2 and c = 0 to y = mx+c,
y = 2x + 0
y = 2x
hence, the equation that best represents the relationship shown in the graph is y = 2x.
Answer:
C. The situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.
Step-by-step explanation:
The initial number of accidents = 5200 = Po
It increases 5% every year.
So r = 5% = 0.05
y = Po(1 + r)^x
y = 5200(1 + 0.05)^x
y = 5200(1.05)^x
This sequence is an exponential. Which is a geometric sequence.
Answer: C. The situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.
Thank you.
