4 x 7 = 28 - 30 = -2. His change is 2 dollars.
100x 0.18 as it equals 18 when you multiply it
Answer:
Step-by-step explanation:
First off, steam isn't a math website.
On discord, it doesn't show steam specifically, but if you're playing a game THROUGH steam then yes, it will show.
To hide this, go to options -> game activity -> and disable "Display currently running game as a status message" on discord.
If you want to hide your status on steam, just put your status to invisible :)
Answer: We should reject the null if the test statistic is greater than <u>1.895</u>.
Step-by-step explanation:
We assume the population to be normally distributed.
Given: Sample size : , which is asmall sample (n<30), so we use t-test.
We always reject the null hypothesis if the absolute t-value is greater than critical value.
Therefore, We should reject the null if the test statistic is greater than <u>1.895</u>.
Number of aircrafts = 2939.93 + 233.517 * (years since 1990).
The predicted number of aircrafts flying in 1992 (1922 does not make sense for this equation because it returns a negative number of aircrafts) is found by pluging in the years since 1990 to 1992 = 1992 -1990 = 2 =>
number of aircrats = 2939.93 + 233.517 * (2) = 3406.96.
That is the predicted number.
The actual number is on the graph. You just go to the explanatory value 2 (years since 1990) on the horizontal axis, move straight upward until you reach the corresponding point on the graph, and read its vertical coordinate (go horizontally to the left until the vertical axis)
