Answer:
Step-by-step explanation:
Remark
<u>Question One</u>
It's equilateral. All three sides are equal. The base is 34 as well. So two right angles can be formed on the base by dropping the altitude from the top vertex.
Givens
altitude = h
a = 34/2 = 17
hypotenuse = 34
Formula
a^2 + h^2 = c^2
Solution
17^2 + h^2 = 34^2
289 + h^2 = 1156
h^2 +289 =1156
h^2 = 1156 - 289
h^2 = 867
sqrt(h^2) = sqrt(867)
h = 29.444
==============
<u>Question Two</u>
Givens
b = 10 feet
c = ?
height = h = 16
Formula
c^2 = b^2 + h^2
Solution
c^2 = 10^2 + 16^2
c^2 = 100 + 256
c^2 = 356
sqrt(c^2) = sqrt(356)
c = 18.87

i can have a rectangle whose length is extremely close to 0 (ie 1 X 10⁻⁴⁴⁴⁴⁴⁴⁴⁴)
and have an extremely wide width. But it's still a rectangle that has perimeter 60.
Answer:
The new mean is 76.2
Step-by-step explanation:
Given
Given
Old mean = 71.3
Every observation is increased by 4.9.
Let the data set has N entries, then
The new mean would be
(71.3 *N + 4.9*N)/N
The new mean = 71.3 + 4.9 = 76.2
