As a percent : 124%
As mixed fraction : 1 6/25
As improper fraction : 31/25
Answer:
i think the answer is 7
Step-by-step explanation:
Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
Answer: <span>The probabilit</span>y is 0.1056
Step-by-step explanation:
f(x) × g(x)
= (x2 + 5x )× (3x2 -4x )
=3x4 + 15x3 - 4x3 -20x2
3x^4 + 11 x3 - 20x2
Given:
The vertices of the triangle are (-10,-3), (1,4) and (-1,7).
To find:
The perimeter of the triangle.
Solution:
Distance formula:

Let the vertices of the triangle are A(-10,-3), B(1,4) and C(-1,7).
Using distance formula, we get





Similarly,


Now, the perimeter of the triangle is




Therefore, the perimeter of the triangle is 30.098 units.
