B. I promise it’s b because I took the test
Answer:
k = 3, q = 9
Step-by-step explanation:
hmm.... what k will end up giving that 6x on the right side of the equation?
Since 6x is the second thingy in that expression, its a good idea to try dividing by 2, lets try k = 6/2 = 3!
(x+3)^2 = x^2+3x+3x+9
(x+3)^2 = x^2+6x+9
that fits pretty good!
So, k = 3, q = 9
Well, if the truck traveled for one hour, that means the car traveled for two.
60+70+70=200
It's not that difficult to just guess and check, even if it's a bit time consuming.
Let's try three hours for the truck.
60+60+60+70+70+70+70=460
That's too much, so we'll try two hours.
60+60+70+70+70=330
The truck traveled two hours, and the car traveled three hours, since the car traveled one hour longer than the truck.
All together, the car and truck drove a total of 5 hours.
Answer:
Step-by-step explanation:
Volume = mass * density
<u>Substitute values and calculate:</u>
- V = 618.7 * 2.7 = 1670.49 mL
Answer:
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
Step-by-step explanation:
Alpha, α = 0.05
We conduct a hypothesis test at 5% significance level.
The null hypothesis will be rejected when
Option (B) a 95% confidence interval does not include the hypothesized value of the parameter
- When a 95% confidence interval is constructed,it contains all the possible values for the parameter being estimated.
- If the value of the parameter stated in the null hypothesis is contained in the 95% confidence interval, then we fail to reject the null hypothesis 0.05 level and accept it.
- If the value stated in the null hypothesis is not in the interval, then we fail to accept the null hypothesis and reject the null hypothesis at the 0.05 level.
