Answer:
[-6, 8]
Step-by-step explanation:
Domain: set of all possible <u>input</u> values (x-values)
Range: set of all possible <u>output</u> values (y-values)
The <u>closed circles</u> on the <u>endpoints</u> of the curve mean that those points are <u>included</u> in the interval.
From inspection of the graph, the smallest y-value is -6 and greatest y-value is 8.
To express this in <u>interval notation</u> write the beginning and ending numbers of the interval inside <u>square brackets</u> as the end values are <u>included</u>.
(If the circles were open, and therefore the end values should not be included, use curved brackets).
Therefore the range of the given graph is: [-6, 8]
Answer:
<u>953.78in^3</u> of grain
Step-by-step explanation:
You use the equation π r^2 h to find the volume of the cylinder
r = radius of the base = 9/2
= 4.5 in and the height h = 15 in
the volume is 3.14 * 4.5^2 * 15
= 953.78 in^3.

Answer: a) 0.1216
b) 0.8784
Step-by-step explanation:
Let P(watch) = 0.19 ;
And p(don't watch) = 0.81
Find the probability that none of the households are tuned to Found.
P(none) = (0.81)^10 = 0.1216
Find the probability that at least one household is tuned to Found.
P(at least one) = 1-P(none)
1 - 0.1216 = 0.8784
Answer:
-240°, -600°
Step-by-step explanation:
Coterminal angles are angles that land in the same spot around a circle.
So, that means they do full turns of the circle to reach each other.
To find coterminal angles of a given angle (here 120 degrees), you add or subtract 360 (the number of degrees in a full circle). That can go in both positive or negative directions.
So, from 120 degrees, let's find the coterminal angle that is 1 rotation above and one rotation below:
120 + 360 = 480
120 - 360 = -240
You see that 480 isn't among the possible answers, so one part of the answer is -240. If you subtract another 360 degrees, you end up with -600 degrees... so the answer is -240°, -600°
