Answer:
The rule is y = -7x + 5
→ Other values of x;
→ Other values of y;
Step-by-step explanation:
» Take points (1, -2) and (3, -12) from the table.
☑ General equation of a line is y = mx + c
- m is the slope
- c is y-intercept

Answer:
a) The required sample size n= 55011,57025
b) The sample size is not practical, because that size is extremely large and would be very costly to collect, normally the size have to be significant but no to large to avoid cost unnecessary
Step-by-step explanation:
Range

⇒ 0,99
Sample size can be determinate using equation:
Using confidence level desired 99%
= 2,58
Table used :
<em>Confidence
</em>
<em> 90 % 1,60</em>
<em> 95 % 1,96</em>
<em> </em><em> 99 % 2,58</em>
<em> 99,9 % 3,291</em>
So replacing:

<span>The <u>correct answers</u> are:
x=-3 and x=-8.
Explanation<span>:
We can first write this in standard form, ax</span></span>²<span><span>+bx+c=0. To do this, we will add 11x to both sides:
x</span></span>²<span><span>+24+11x=-11x+11x
x</span></span>²<span><span>+11x+24=0.
Now we can factor this. Look for factors of c, 24, that sum to b, 11. Factors of 24 are:
1 and 24 (sum 25)
2 and 12 (sum 14)
3 and 8 (sum 11)
4 and 6 (sum 10).
The factors we need are 3 and 8, since they sum to 11. This gives us factored form:
(x+3)(x+8)=0.
Using the zero product property, we know that in order to have a product of 0, one or both of the factors must be 0. This means we have:
x+3=0 or x+8=0.
Solving the first equation:
x+3-3=0-3
x=-3.
Solving the second equation:
x+8-8=0-8
x=-8.</span></span>
