Answer:
Terms:
<em>5, 2x, 4, 3x</em>
Coefficients:
<em>2 in 2x, and 3 in 3x</em>
Constants:
<em>5 and 4</em>
Factors:
<em>5, 2x, and 4</em>
Step-by-step explanation:
For terms, all of them are terms because they are all in the expression.
For coefficients, coefficients are ones that have a variable (think of it as a <em>copilot</em> kind of thing).
For factors, factors are terms that are multiplied together together to get a <em>product</em> (the answer).
For constants, these are terms that stand alone, by themselves. They are not attached to variables.
The answer is <em>13x + 20, </em>too, just in case you needed that.
Have a great day and hope this helps!
Answer:
12
Step-by-step explanation:
3 divided by 1/4 = 3 x 4 = 12
First calculate the function of x-2y=6:
x-2y=6 | - x
-2y=6-x | ÷ (-2)
y=0.5x-3
Now you have the function. Because the slope you search is parallel to this one, the slope is the same (in this case 0.5). A slope of 0.5 means for 2 steps to the right go one up. To define the function you are searching you have to find out the y intercept. For this take your point (-2|4). Now go as many steps to the right until you reach the y intercept or x=0 in this case you need 2 steps. So for 2 steps right you go one up. Now you have the y intercept (5).
The resulting function is: f(x) = 0.5+6.
Answer:
The 95% confidence interval for the population variance is (8.80, 32.45).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the population variance is given as follows:
It is provided that:
<em>n</em> = 20
<em>s</em> = 3.9
Confidence level = 95%
⇒ <em>α</em> = 0.05
Compute the critical values of Chi-square:
*Use a Chi-square table.
Compute the 95% confidence interval for the population variance as follows:
Thus, the 95% confidence interval for the population variance is (8.80, 32.45).
