Answer:
<em>The answer would be 8x + 24</em>. And it's not a trinomial form. Why? Maybe the given is not just (3+5), it's (3x+5). So that we can get trinomial product.
Sol.
(x + 3) (3x + 5)
Each parenthesis has a binomial (two numbers)
A. Note that whenever you have two parenthesis next to each other like this, it implies factoring. So let's factor.
3x^2 + 5x + 9x + 15
We get a quartnomial (containing 4 numbers), but we're looking for a trinomial. Can we reduce this?
B. Yeah, so we reduce
3x^2 + 14x + 15
There you go, this is a trinomial.
Answer:
Is the question to develop the equation for the straight line shown?
If so,<u> y = (3/4)x + b</u>
Step-by-step explanation:
Look for an equation with the form y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
Calculate Slope using the Rise/Run.
Pick any two points. I chose (-4,0) and (4,6).
Going from left to right:
Rise = (6 - 0) = 6
Run = (4 - (-4)) = 8
Slope is Rise/Run, 6/8 or 3/4
So we have: y = (3/4)x + b
We can see that the y-intercept, b, is 3 (the value of y when x = 0).
The full equation becomes :<u> y = (3/4)x + 3 </u>
double x + 3= 2x + 6. double four is 8. 8 * 2x + 6 = 16x + 48
Answer:
D. No, because 50% is within the bounds of the confidence interval.
Step-by-step explanation:
"52% of registered voters plan on voting for Robert Smith with a margin of error of plus or minus±3%"
This means that the 95% confidence interval for the percentage of people that plan on voting for Robert Smith is
(52-3 = 49%, 52+3 = 55%).
We can't say that he will win the election, because at the 95% confidence level, the proportion is not guaranteed to be above 50%.
So the correct answer is:
D. No, because 50% is within the bounds of the confidence interval.
Answer:
Yes, C is the correct answer
