Answer
C
Area of a circle is pi r to the power of 2.
so the radius is 6
so pi(6)^2= 36pi
Answer:
29
Step-by-step explanation:
(7-5)^2 is 4 and (20-19)^2 is 1
4+1=5
3*5=15
15+14=29
Area if the rectangle = 42 sq. inch
Area of a rectangle = l × b
42 = 12 × b
b = 42/12 = 3.5 inch
Now, perimeter of a rectangle= 2(l + b)
= 2(12+3.5) = 2(15.5) = 31 inches
well i cannot help u graph but u need to get them in y=mx+b form first
2x+y=4
y=-2x+4
2y-4x=6
2y=4x+6
y=2x+3
now that the problems are in y=mx+b form, u can graph them. the "b" is your y-intercept. you need to graph this first so what ever ur be is, put a point there on the y axis. then use your slope to plant your line. slope is rise/run. so for the top problem start at your y intercept and go down 2 and to the right 1. and for the bottem problem, start at your y intercept then go up 2 and to the right 1
HOPE THIS HELPED!
I believe the answer is A, the standard deviation is preferable to the range as a measure of variation because the standard deviation takes into account all of the observations, whereas the range considers only the largest and the smallest. Range gives an overall spread of data from the lowest to the largest and thus can be influenced by anomalies, standard deviation on the other hand, takes into account the variable data/spread about the mean and allows for statistical use so inferences can be made.<span />
