Answer:
Odd number: 13/25 (52%)
Multiples of 5: 5/25 (20%)
Step-by-step explanation:
There are 13 odd numbers between 1 and 25 so you have a 13/25 chance which is 52% (13/25 = 0.52). There are 5 multiples of 2 between 1 and 25 so you have a 5/25 chance which is 20% (5/25 = 0.2).
X^2+2x-5x-10
x(x+2)-5(x+2)
(x-5)(x+2)
The answer is Translation since the shape never changed any angle or position it is safe to say that they just used a translation to move it.
<u>Answer:</u>
The element is Chromium.
<u>Explanation:</u>
The atom has 24 protons and 12 neutrons.
We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)
Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.
So, the atomic number is 24 and the atomic mass is (24+12)= 36
Therefore, the symbol is 
Answer:
b = - 21
Step-by-step explanation:
calculate m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (- 6, 3)
m =
=
= - 4
y = - 4x + b ← is the partial equation
to find b substitute either of the 2 given points into the partial equation
using (- 4, - 5 ), then
- 5 = 16 + b ⇒ b = - 5 - 16 = - 21
