Answer:
4a² - 3
Step-by-step explanation:
24a²-18 = 6 x (4a² - 3)
3 3/8= 27/8
27/8= 81/24
5/12= 10/24
91/24
3 19/24
I'm pretty sure that's the answer in simplest form
Answer:
Step-by-step explanation:
The happiest used in a test in statistics are the null and the alternative hypothesis. The null hypothesis is usually the default statement while the alternative hypothesis is thevopposite of the null hypothesis.
In this case study, the null hypothesis is u1 = u2: the average mean time it takes to accelerate to 30 miles per hour for car 1 is the same as that for car 2.
The alternative hypothesis is u1 > u2: the mean time it takes to accelerate to 30 miles per hour is greater than that for car 2 thus car 1 is slower to accelerate as it takes more time.
Answer:
(-5, 3)
Step-by-step explanation:
Let O(x, y) be the centroid of the triangle.
The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.
The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.
For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:
The centroid is at (-5, 3)
Answer:
Circumference would be 25.12ft
Step-by-step explanation:
So circumference formula is pi(diameter)
We know the radius so to find the diameter we multiply the radius by 2.
so 4(2)=8
and since pi is 3.14 then multiply 8(3.14)
youll get 25.12
