Answer:16x-6
Step-by-step explanation:4(4x-1) distributed is 16x-6
Answer:
29 degrees
Step-by-step explanation:
The arc intercepted by inscribed angle x = 360 -180 -122 = 58 degrees
inscribed angles intercept twice as many degrees of arc
x = 58/2 = 29 degrees
It is a
9/4=2.25*2=4.5
Hope it helps :)
So because of PEMDAS you want to distribute the 2 to the parentheses so you'll get
6x-19=2x-2+11
Then you can just add like terms
6x-19=2x+9
Now you want to get all your variables on one side so you'd add 19 and subtract 2x
4x=28
Now you divide 28 by 4
x = 7
Answer:
True.
Step-by-step explanation:
If we have for a sample of size n=25 a sample variance of 400, the standard error can be written as:

This way of calculating the standard error is the same used for estimating the standard deviation of the sample means for samples of size n=25.
