Answer:
A = 10.5%
B = 28.9%
C = 39.5%
D = 18.4%
F = 2.6%
Step-by-step explanation:
Add all the frequencies together = 38
- 4/38 × 100 = 10.5%
- 11/38 × 100 = 28.9%
- 15/38 × 100 = 39.5%
- 7/38 × 100 = 18.4%
- 1/38 × 100 = 2.6%
10.5 + 28.9 + 39.5 + 18.4 + 2.6 = 100%
Answer:
Step-by-step explanation:
Proportional functions can be represented by 
, where 
is a constant of proportionality and 
represents any point the line passes through.
In the graph, we can see the line passes through (20, 40). Therefore, we can plug in these coordinates to find the constant of proportionality:
(a-b)^2 = a^2-2ab+b^2
(8-5i)^2 = 8^2-2(8)(5i)+(5i)^2
= 64-80i+25i^2
i^2=-1
So
= 64-80i+25(-1)
=64-25-80i
= <em><u>39 - 80i</u></em>
which is your answer :)
Answer:
x = -6/5
Step-by-step explanation:
distribute -4 on the left side of the equation first, then distribute 2 on the right side of the equation to get:
16x - 4 - 4x = 2x - 14 - 2
combine 'like terms':
12x - 4 = 2x - 16
subtract '2x' from each side to get:
10x - 4 = -16
add 4 to each side to get:
10x = -12
x = -12/10 or x = -6/5
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :
Here, a = -9, b = 2 and c =3
Put the values,
So, the solution are -0.47 and 0.69.
