Answer:
What I would conclude when a random sample of 23 time intervals between eruptions has a larger mean longer than 108 minutes is that there must be an error that occurred somewhere while computing the result.
Step-by-step explanation:
Technically error can be explained as the estimated difference between the real value or calculated value and an observed value of a certain quantity.
basically we have three types of error which are;
1. systematic errors.
2.random errors.
3.Bluders.
Answer:
Answer:
Pythagoras law:h²=p²+b²
needed to apply
4²+8²=12²
80≠144 not a right angled triangle
again
2²+√5²=3²
9=9/
<em><u>side</u></em><em><u> </u></em><em><u>are</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>right</u></em><em><u> </u></em><em><u>angled</u></em><em><u> </u></em><em><u>triangle</u></em>
again
2²+2²=(√8)²
4+4=8
8=8
<em><u>side are a right angled triangle</u></em>
8 - 2 = 6
6 - 1 = 5
9 x 5 = 45
Answer: hay 16 vagones de pasajeros y 48 de carga
Step-by-step explanation:
To factor a trinomial, first we should factor out the GCF, or greatest common factor, shared by all of the coefficients and constants. The greatest common factor of -3, -21, and -30 is -3, therefore, this is the number we must factor out first.
When we factor out the GCF of -3, we get:
-3(q^2 + 7q + 10)
Next, we must look for two numbers that will serve as coefficients for the variables in factored form. These two numbers must add to 7 (the middle term) and multiply to 10 (the constant or last term). The two numbers that satisfy these parameters are 5 and 2.
Therefore, we must use these numbers to create factors of the innermost factor that we have left, to get:
-3(q+5)(q+2)
The above expression is your final answer, because you cannot factor any more. And remember: you can always check to make sure that your factoring is correct by multiplying out the factors and making sure you get your original trinomial.
I hope this helps!
