-(1.5, -3)
think of the y axis intercepting the x axis at coordinates (0,0)
-they then said their point is 1.5 left of the y axis
-now all you have to do is to find another x value of that same distance (x,y)
Answer:
Pattern seen is arithmetic progression. The both equations are same.
Step-by-step explanation:
a.The given pattern is 8,12,16,20,24....We can see that the difference between any two consecutive terms is 4.Therefore this is an AP(arithmetic progression).
b.Percy's equation , 
⇒
⇒
⇒
which is the same as Stella's equation . So , we can see that both equations are the same.
Diameter = 10.0002 inches, or 10 inches since were rounding to the nearest whole number.
Answer:
Graph D
Step-by-step explanation:
So we have 5 Batting averages and their respective frequencies.
0.330-339 is the most occurring batting average (14 times)
Now look at the histograms, you should be looking for a peak at 0.330-339.
There is only one histogram that represents peak at 0.330-339 and that is Graph D.
All other options depict wrong peaks at either 0.340-0.349 or 0.350-0.359
We know for sure that 14 is greater than all other frequencies so there must be a peak corresponding to the average of 0.330-339.
Answer:
The area of the circle is 19.5 in²
Step-by-step explanation:
First of all to solve this problem we have to know the formula to calculate the volume of a cone
v = volume = 52 in³
r = radius
h = height = 8 in
π = 3.14
v = 1/3 * π * r² * h
we solve r
3 * v /h * π = r²
we replace the known values
3 * 52 in³ / 3.14 * 8 in = r²
156 in³ / 25.12 in = r²
6.21 in² = r²
√6.21 in² = r
2.49 in = r
now that we have the radius we need to use the area formula of a circle:
a = area
r = radius = 2.49 in
π = 3.14
a = π * r²
we replace the known values
a = 3.14 * (2.49 in)²
a = 3.14 * 6.21 in²
a = 19.5 in²
The area of the circle is 19.5 in²
