Answer:
y=3x^2-24x +52
group x's:
y=(3x^2-24x) +52
factor out a 3:
y=3(x^2-8x) +52
complete square:
y=3(x^2-8x+16) +52 - (3*16)
y=3(x^2-8x+16) +52 - 48
y=3(x^2-8x+16) 4
y=3(x-4)^2 +4
Step-by-step explanation:
Hello!
We can solve this algebraically
7 = p - 3/5(10p - 5)
Distribute the -3/5
7 = p - 6p + 3
Combine like terms
7 = 5p + 3
Subtract 3 from both sides
4 = 5p
Divide both sides by 5
4/5 = p
The answer is 4/5
Hope this helps!
Answer:
0
Step-by-step explanation:
the x after the 10 is literally just 1
so 10 x 1 =10
-10 + 10 = 0
Answer:
1) x ≤ 30
2) 5x + 2x ≥ 14
3) x × y ≤ 4
4) y - 5 < 20
Step-by-step explanation:
At most means " no more than, " " less than or equal to, " or " not greater than"
The math symbol that you will use for at most is ≤
At least means " no less than " or " greater than or equal to "
The math symbol that you will use for at least is ≥
Answer:
One can be 95% confident that the drive-through service times of fast-food chain is between 169 seconds and 172 seconds.
Step-by-step explanation:
The confidence interval gives a range of value for the population mean or parameter, which is calculated from the statistic value of the data (that is sample statistic). This range gives the interval which is associated with a certain level of confidence for which the interval will contain the true value of the unknown parameter (true value). In the scenario above, the associated confidence level is 95%.Hence, we can be 95% confident that the true value will be continued with the interval (169 ; 172)
