Answer:
3.98
Step-by-step explanation:
First, let us go to the second decimal place. the number here is 7, the number after is 5 which is greater than or equal to 5. Thus we round the 7 up to 8 giving us
3.98
Answer, Step-by-step explanation:
According to the exercise, we evaluate the delivery time of a courier company and we will hypothesize the best case with a sample size of 10, which is:
Small sample T test for single mean
The hypothesis that we will develop will be the following:
null hypothesis = mu> = 6
hypothesis alternativa: <6
Here is the equation: (gas=g)
8.5g= 23.94
All you need to do is the inverse of multiplication on the other side. (division)
23.94/8.5= 2.81647.....
g= 2.82 (rounded to the hundredths place)
I hope this helps!

Answer:
det(A) = (-6)(-2) - (-4)(-7)
Step-by-step explanation:
The determinat of the following matrix:
Is given by: Determinant a*d - b*c
In this case, a=-6, b=-7, c=-4 and d=-2.
Therefore the determinant is: (-6)(-2) - (-7)(-4).
Therefore, the correct option is the third one:
det(A) = (-6)(-2) - (-4)(-7)
Answer:
x = 3√2 , y = 6
Step-by-step explanation:
In given triangle,
3√2 = x
and y is hypotenuse.
Using Pythagoras theorem
hypotenuse = √Perpendicular² + Base²
hypotenuse = √(3√2)² + (3√2)²
hypotenuse = √18 + 18
hypotenuse = √36
hypotenuse = 6
So,
x = 3√2 , y = 6
