2 x 10 to the 3rd power is
2x10^3
There are 22 fourths in 5 1/2
Answer:
0.23
Step-by-step explanation:
Given the data:
____(x) __(y)__(x - m1) /s1 ___(y-m2) /s2
1 ___6 ___8__ - 0.2 _______0.625
2 __5 ___ 5__ - 0.7________ - 1.25
3 __9____6__ 1.3 ________ - 0.625
4__ 4____ 7__ - 1.2 ______ 0
5__ 8 ____9 _ 0.8 _______ 1.25
For English :
Mean score(m1) = 6.4
Standard deviation (s1) = 2.0
For Science :
Mean score (m2) = 7.0
Standard deviation (s2) = 1.6
n = number of observations = 5
Correlation Coefficient (r) :
r = 1/(n - 1) Σ[((X - m1) / s1) * ((Y - m2) /s2)]
(-0. 2 * 0.625) + (-0.7 * - 1.25) + (1.3 * - 0.625) + (-1.2 * 0) + (0.8 * 1.25) = 0.9375
r = 0.9375/(5-1)
= 0.234
= 0.23
Answer: the length of each of the congruent sides is 29 inches.
The length of the third side is 22 inches.
Step-by-step explanation:
In an isosceles triangle, two sides are equal. The base angles are also equal.
Let x represent the Length of each of the congruent side.
The congruent sides are 7 inches longer than the third side of the triangle. This means that the length of the third side of the triangle is
x - 7
The formula for determining the perimeter of a triangle is
a + b + c
Where a, b and c are the length of each side of the triangle.
If the isosceles triangle has a perimeter of 80 inches, it means that
x + x + x - 7 = 80
3x - 7 = 80
3x = 80 + 7 = 87
x = 87/3 = 29 inches
The length if the third side would be
29 - 7 = 22 inches
