Answer:
Meter
Step-by-step explanation:
The standard unit of length based on the metric system is a meter (m). According to the length that needs to be measured, we can convert a meter into various units like millimeters (mm), centimeter (cm), and kilometer (km).
Answer: the graph farthest to the right is almost correct. If you substitute values for x in the function f(x)= -3√x , the output does not match the curve on the graphs shown.
If you have a choice that includes only a curve to the right of the y- axis, that would be better.
Step-by-step explanation: Square roots of Negative x-values will result in imaginary numbers. Otherwise the graph with the curve passing through coordinates (1,-3) (4,-6) and (9,-9) is a good choice.
(And ask your teacher about the square root of negative numbers on this graph.)
Answer:
Step-by-step explanation:
Total number of trials =600.
Number of heads = 342.
Number of tails = 258
On tossing a coin,
![let \: E_1 \: and \: E_2 \: be \: the \: events \: of \: getting \: a \: head](https://tex.z-dn.net/?f=let%20%20%5C%3A%20E_1%20%20%5C%3A%20and%20%20%5C%3A%20E_2%20%20%5C%3A%20be%20%20%5C%3A%20the%20%20%5C%3A%20events%20%5C%3A%20%20of%20%5C%3A%20%20getting%20%20%5C%3A%20a%20%20%5C%3A%20head)
