Answer:
x>2
Step-by-step explanation:
3x + 5 < 6x -1
subtract 6x on both sides
3x - 6x + 5 < -1
subtract 5 on both sides
-3x < -1 -5
-3x < -6
divide -3 on both sides
x > 2
Answer: 0.0328
Step-by-step explanation:
Standard error is the standard deviation of the sampling distribution.
The formula to find the standard error is given by :-
,where n= sample size.
= Sample proportion.
Given : Of the 2266 high school students surveyed, 952 admitted to smoking marijuana at least once.
A study done 10 years earlier estimated that 45% of the students had tried marijuana.
i.e. Population proportion : p= 0.45
Sample size : n= 226
Sample proportion : ![\hat{p}=\dfrac{952}{2256}\approx0.42](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cdfrac%7B952%7D%7B2256%7D%5Capprox0.42)
Then , the standard error for this test will be :-
Hence, the standard error for this test= 0.0328
Answer:
12 - m = 20
Explanation: Less than can also be a subtraction symbol so 12 less than a number, which the number is unknown in this case would be replaced with m then equals to 20. 12 - m =20
Let the variable "b" represent the number of bagels you buy
let the variable "R" represent the amount of money you have left
R = 25 - 1.25b
is your equation
then to find out after you bought 2 bagels
R = 25 - 1.25(2) = 25 - 2.5 = 22.5
do you would have $22.50 left on the card after you buy 2 bagels
