Answer:
-2sqrt(3)/3
Step-by-step explanation:
cosec(300) = -cosec(360-300)
= -cosec(60)
= -1/sin(60)
= -1/(sqrt(3)/2)
= -2/sqrt(3)
= -2sqrt(3)/3

The sample proportion is never a point estimate of the population proportion. I need help ASAP
Step-by-step explanation:
Hello!
In order to find the x-intercepts of the graph, we need to use the zero product property.
The zero product property states: if a · b = 0, then a = 0 or b = 0.
(x + 1)(x + 4)(x - 7) = 0 With this equation, we can find the x-intercepts.
x + 1 = 0 (subtract 1 from both sides)
x = -1
x + 4 = 0 (subtract 4 from both sides)
x = -4
x - 7 = 0 (add 7 from both sides)
x = 7
Therefore, the x-intercepts of the graph of this function is x = -1, -4, 7 or (-1, 0), (-4, 0), and (7, 0).
Choose the most appropriate unit to measure the weight of each.
Write oz., lb., or T.
#1. Car = T
#2. Computer = lb.
#3. Bowling Ball = lb.
#4. Onion = oz.
#5. Tyrannosaurus Rex = T.
#6. Vacuum Cleaner = lb.
#7. Q. A hippo weighs about 5,000 lb.. Does the same hippo weigh more or less than 5,000 oz.?
A. If one ounces is 0.0625 pounds then 5000 ounces are 312.5 pounds so the same hippo weighs more than 5,000 oz.
