Answer:
The variance of the temperatures of the 10 day period must be at least zero.
Step-by-step explanation:
The variance is the expectation of the squared deviation of a random variable from its mean. It measures how far a set of numbers are spread out from their average value.
Its unit of measure corresponding to the square of the unit of measure of the variable. In this case, the variance of the temperatures is expressed in (°C)². The variance has a minimum value of 0.
Since the variance is squared, it will always have values greater than zero.
Answer:
The number of trees in a garden is discrete because you can count them easily.
Step-by-step explanation:
Discrete= The amount of something that is counted.
Continuous= Something that has to be measured.
Hope that helps. x
Answer:
Selena is correct because she simplified correctly and then evaluated correctly after substituting the values for the variables.
I did this lesson i asked my teacher to help me but i did this problem on my own so i hope its right :)
Step-by-step explanation:
I'm not sure what your variables are, but I will try task 3 with you.
y=$500(in billions)
x= the number of years that have passed since 2009
percentage of decrease: 1 - % =
so your formula will look like this: y(1 - %)^x
