This is the steps for equation solving for the value of x,
x/3-7 = 11
now 7 goes to the other side of equation by changing the sign from - to +,
x/3 = 11 + 7
x/3 = 18
now when we multiply both sides of equation with 3 or 3 goes to the other side of equation and multiply with 18 leaving x alone here for finding the value of x,
and we get, x = 54
at the end of equation we get x = 54, if the equation was in the form 3x - 7 = 11, then we will get x = 6
The answer is 6,811.1
The reason the 0 moved up to a 1 is because the number in the hundredth place was 5 or over. If it were 4 or under, then it would have remained a 0.
Answer: 1.303639
Step-by-step explanation:
The t-score for a level of confidence 
is given by :_
, where df is the degree of freedom and 
is the significance level.
Given : Level of significance : 
Then , significance level : 
Sample size : 
Then , the degree of freedom for t-distribution: 
Using the normal t-distribution table, we have
Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639
Answer:
I'm pretty sure it's 13.
Step-by-step explanation:
Answer:
y=(-2/5)x
Step-by-step explanation:
Assuming that the goal is to find the linear equation in slope-intercept form, this problem is pretty simple.
Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. We just have to plug in the information
y=(-2/5)x+0
Simplifies to:
y=(-2/5)x
